Description

Implants and implant systems Technical Field

[0001] The present disclosure relates to the field of interventional medical devices, and in particular to an implant with a wireless sensor and an implant system. Background Art

[0002] For patients with cardiovascular diseases, therapeutic devices placed in the heart or blood vessels can improve the symptoms caused by heart or blood vessel diseases. For example, some patients need to install occluders in their hearts or blood vessels to improve cardiovascular function, and some patients with vascular diseases need to implant vascular stents. In addition to treating related symptoms through therapeutic devices, it is also very meaningful to monitor the hemodynamic parameters of the patient's cardiovascular system. For example, for patients with heart failure, in addition to implanting shunts, atrial pressure monitoring is also a very important disease management method. However, since implants are usually very small in size, have different shapes, and are usually made of metal, they are prone to interference with wireless signals. Therefore, how to combine monitoring devices with different types of therapeutic devices without generating new signal interference factors during the combination process and without significantly increasing the overall size is a major technical difficulty in this field.

[0132] The following is an exemplary description of the embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the present disclosure can be implemented in many ways and should not be construed as being limited to the embodiments described herein. The embodiments described herein are only for a more thorough and complete understanding of the present disclosure.

[0133] It should be understood that the term "including" and its variations used in the present disclosure are open inclusions, ie, "including but not limited to." The term "according to" means "at least in part according to."

[0134] It should be understood that although the terms “first” or “second” etc. may be used in the present disclosure to describe various elements, these elements are not limited by these terms, and these terms are only used to distinguish one element from another.

[0135] An embodiment of the present disclosure provides an implant for implantation into a target site in a living body. The implant includes a therapeutic device, a wireless sensor, and a connector. The therapeutic device is used to be arranged at a target site to improve the physiological function of the living body; the wireless sensor includes a detection element and a wireless signal transmission element, which are used to monitor target physiological parameters in the living body. The detection element is used to obtain target physiological parameters, and the wireless signal transmission element is used to transmit the target physiological parameters obtained by the detection element to the outside of the living body, such as a remote controller; wherein the connector is used to connect the housing of the wireless sensor to the therapeutic device, and the connector is configured to retain the signal transmission path of the wireless signal transmission element when connected to the housing. Specifically, the connector retains the signal transmission path of the wireless signal transmission element by selecting one or more of its own materials, structures, and setting positions, thereby preventing the signal transmission path of the wireless signal transmission element from being blocked or shielded due to the setting of the connector. Of course, the operator can also send wireless signals to the wireless signal transmission element through a remote controller to perform two-way signal transmission, and this application does not impose any restrictions on this; the "signal transmission path" referred to in this application can also be understood as a virtual path for the signal to be transmitted from the wireless signal transmission element in the shell to the outside of the organism or from the outside of the organism to the wireless signal transmission element in the shell. When the wireless signal is transmitted through the signal transmission path, the wireless signal transmission element has the ability to transmit the signal.

[0136] Furthermore, the wireless sensor further includes a shell, and the detection element and the wireless signal transmission element are arranged in the shell.

[0137] When the connector is made of metal, the connector does not completely surround the shell (for example, the connector has an opening) so that the signal of the wireless signal transmission element of the wireless sensor is not blocked or shielded by the connector, or the connector and the wireless signal transmission element are staggered so that the signal is not blocked or shielded by the connector. When the connector completely surrounds the shell, a non-electromagnetic shielding structure (for example, a non-metallic material sleeve) can be used to connect the shell so that the signal transmission path of the wireless signal transmission element will not be blocked or shielded by the connector. The shell is made of non-metallic materials, such as glass, and will not block or shield the signal transmission path. Electromagnetic shielding structure refers to a closed metal cover, metal cage or other structure that can shield electromagnetic signals. Non-electromagnetic shielding structure does not include the above structure and will not shield electromagnetic signals. In this way, the implant can achieve therapeutic and diagnostic effects at the same time, and can prevent the signal of the wireless sensor from being affected by the implant or connector, thereby achieving more accurate signal transmission.

[0138] Refer to Figures 1 and 2. Figure 1 is a schematic diagram of an implant and its application scenario according to an embodiment of the present disclosure. Figure 2 is a structural schematic diagram of the wireless sensor 200 of the implant in Figure 1. The implant includes a treatment device 100, a wireless sensor 200 and a connector 300. The wireless sensor 200 can be hung on the treatment device 100. In this embodiment, the treatment device 100 is a valve stent, which can be used to treat valve diseases between the left atrium and the left ventricle. The wireless sensor 200 is a sensor that can detect fluid pressure and can wirelessly transmit relevant signals to an external receiver. In some optional embodiments, the detection element can also be a detection device for detecting physiological parameters such as blood oxygen saturation, acceleration, pH value, blood viscosity, and temperature.

[0139] The treatment device 100 is a mesh-shaped stent having an expanded diameter section and a non-expanded diameter section, wherein the expanded diameter section has a larger diameter than the non-expanded diameter section. In this embodiment, the wireless sensor 200 is connected to the lower edge of the non-expanded diameter section of the treatment device 100.

[0140] The wireless sensor 200 includes a detection element 210 and a wireless signal transmission element 220. The detection element 210 is used to detect fluid pressure data. The wireless signal transmission element 220 is used to wirelessly transmit the pressure data outside the human body. In some optional embodiments, the wireless sensor 200 also includes a housing 230, which is used to accommodate the detection element 210 and the wireless signal transmission element 220. The housing 230 is tubular, and a matching structure 231 is provided on the outer peripheral surface of the housing 230. The matching structure 231 is an annular groove, which is used to connect with the connector 300. In some optional embodiments, the wireless sensor 200 may also include an energy supply element for providing electrical energy to the detection element 210 and the wireless signal transmission element 220.

[0141] The connector 300 includes a hooking rod 310 and a hoop 320. The hoop 320 is an open ring structure (i.e., an annular structure with an opening) and is provided with an opening 330 and a receiving cavity 321. The hooking rod 310 is fixed to the outer circumference of the hoop 320 and extends parallel to the axial direction of the hoop 320. The connector 300 is sleeved onto the mating structure 231 of the housing 230 via the hoop 320. The connector 300 is fixed to the bottom of the treatment device 100 via the hooking rod 310, thereby connecting the wireless sensor 200 to the treatment device 100. Specifically, the end of the hooking rod 310 can be welded to the grid of the treatment device 100, connected by crimping, bonding, or other methods, or can be integrally formed with at least a portion of the treatment device 100. In some alternative embodiments, the hooking rod 310 can also have other structures, such as an anchor hook, a sleeve, or a rod, and the corresponding connection structure can be selected according to different treatment devices.

[0142] In this embodiment, the connector 300 is a metal component, thus securely connecting the treatment device 100 and the wireless sensor 200. The hoop 320 of the connector 300 is a thin-walled, open-loop sleeve. This is not circumferentially closed (equivalent to a longitudinal opening in the sleeve wall), thus not shielding electromagnetic signals and not significantly increasing the radial dimensions when connected to the housing 230. Furthermore, the housing 230 is provided with a corresponding mating structure 231 (annular groove) to accommodate the hoop 320, ensuring a smooth outer surface of the wireless sensor 200 without bosses or grooves, thereby preventing thrombosis. Furthermore, the connection between the hoop and the annular groove provides axial positioning, strengthening the connection between the two. In alternative embodiments, the housing 230 may not have an annular groove, with the entire outer surface or a portion of the outer surface of the housing 230 being the mating structure. The hoop 320 is directly mounted on the entire or partial outer circumference of the housing 230. Furthermore, the contact surface between the hoop 320 and the housing 230 can be bonded to enhance connection strength. In other optional embodiments, the housing 230 and the connector 300 are integrally formed, further reducing size, enhancing strength, and reducing assembly complexity. Furthermore, the hoop 320 is provided with an opening 330, thereby preventing signal shielding of the wireless signal transmission element 220. In other optional embodiments, the hoop 320 is a metal open ring structure with an axial length that matches the axial length of the housing 230. The hoop 320 is provided with an opening. The axial length of the opening can match the axial length of the housing 230, or can be less than the axial length of the housing 230 but greater than the axial length of the wireless signal transmission element 220. The opening is positioned corresponding to the wireless signal transmission element 220 of the wireless sensor 200, thereby forming a wireless signal transmission window for wireless signal transmission.

[0143] In some optional embodiments, the hoop 320 is a closed ring structure (i.e., a ring structure without an opening). Correspondingly, in order not to hinder the transmission of wireless signals, the wireless signal transmission element 220 and the detection element 210 are distributed at both ends of the lumen, and the position of the matching structure 231 of the shell 230 is staggered with the wireless signal transmission element 220 in the axial direction. In this way, it is equivalent to retaining the signal transmission path of the wireless signal transmission element 220 by giving way to the connector 300. In other optional embodiments, the hoop 320 is a closed structure and completely covers the shell 230 in the axial direction, but the hoop 320 is a non-shielding material, such as a polymer material. Therefore, the hoop 320 is a non-shielding structure and will not shield the wireless signal of the wireless signal transmission element 220, thereby retaining the signal transmission path of the wireless signal transmission element. The signal transmission path can be a predetermined area in a certain direction at a certain position of the wireless signal transmission element 220 (such as a cylindrical area corresponding to the outer surface of the wireless signal transmission element 220), or it can be the space facing the entire circumference or part of the circumference of the wireless signal transmission element 220. No specific restrictions are given here.

[0144] In some optional embodiments, the number of hooking rods 310 can be two or more, thereby increasing the connection strength between the connector 300 and the treatment device 100. In some optional embodiments, the connector 300 can further include an upper cover or a lower cover connected to the hoop 320. The upper cover and / or the lower cover are sleeved on the end without the housing 230. Preferably, the upper cover or the lower cover and the hoop 320 are integrally formed. In some optional embodiments, the treatment device 100 includes a mesh stent cut from a metal tube, and the hooking rods 310, the hoop 320, and the mesh stent are cut and formed integrally. Alternatively, the hooking rods 310, the hoop 320, the upper cover or the lower cover are cut and formed integrally with the mesh stent, and then expanded through a diameter expansion process. This method can further simplify the connection process between the treatment device 100 and the housing 230 and enhance the connection strength between the two.

[0145] Refer to Figures 3 to 5. Figure 3 is a schematic diagram of the structure of a wireless sensor implanted in another embodiment. Figure 4 is a schematic diagram of the structure of the wireless sensor in Figure 3 from another perspective. Figure 5 is a schematic diagram of the structure of another embodiment of the connector of the implant in Figure 3. Figure 6 is a schematic diagram of the structure of the housing of the wireless sensor in Figure 3.

[0146] In this embodiment, the connector 300a is made of metal. It includes a hooking rod 310a and two hoop rings 320a. The hoop rings 320a are provided with openings 330a. The two hoop rings 320a are spaced a predetermined distance apart in the axial direction. A portion of the hooking rod 310a connects the two hoop rings 320a in series. The wireless sensor 200a is cylindrical in structure, and its housing 230a is provided with two mating structures 231a. In this embodiment, the mating structures 231a are specifically annular grooves, with the axial spacing between the two annular grooves being equal to the axial spacing between the two hoop rings 320a. The two hoop rings 320a of the connector 300a engage with the two mating structures 231a of the housing 230a. The two axial mating structures between the connector 300a and the housing 230a provide a more stable connection. The openings 330a in the hoop rings 320a provide an open ring structure, thus preventing interference with wireless signals. In the embodiment shown in Figure 5, the hoop 320a is further provided with reinforcement holes 321a near the opening 330a. By inserting reinforcement members, such as sutures, through the two reinforcement holes 321a, the connection strength between the connector 300a and the housing 230a can be further strengthened. In some alternative embodiments, the housing 230a may not have an annular groove, and the two hoop rings 320a may be directly mounted on the circumferential surface of the housing 230a.

[0147] The wireless sensor 200a can be connected to a treatment device via a hooking rod 310a. The treatment device can be the valve stent shown in FIG1 .

[0148] Refer to Figures 7 and 8. Figure 7 is a schematic diagram of the structure of an implanted wireless sensor in another embodiment. Figure 8 is a schematic diagram of the structure of the housing 230b of the wireless sensor 200b in Figure 7. In this embodiment, the portion of the connector 300b used to connect to the housing 230b of the wireless sensor 200b is a spiral structure 320b, and the portion used to connect to the treatment device is a hook rod 310b. The hook rod 310b and the spiral structure 320b are formed by bending and winding the same metal strip. The surface of the housing 230b is provided with a matching structure 231b, specifically a spiral groove. The connector 300b is embedded in the spiral groove of the housing 230b through the spiral structure 320b, so that the two can be tightly connected. In addition, the spiral structure 320b is formed by spirally winding a metal strip, without an electromagnetic shielding structure (for example, a metal closed loop structure), and will not hinder the transmission of wireless signals. The spiral structure 320b forms an open-loop cylindrical structure.

[0149] The wireless sensor 200b can be connected to a treatment device via a hooking rod 310b. The treatment device can be the valve stent shown in FIG1 .

[0150] Refer to Figures 9 and 10. Figure 9 is an implant and its application scenario according to another embodiment of the present disclosure. Figure 10 is a structural schematic diagram of the wireless sensor in Figure 9. In this embodiment, the implant includes a treatment device 100c and a wireless sensor 200c. The treatment device 100c is an annuloplasty ring in an open form. The annuloplasty ring shown in the figure is arranged between the two valves between the left atrium and the left ventricle in the heart. Annuloplasty mainly treats symptoms of valvular annular lesions or valvular insufficiency caused by other heart diseases. It can restore the valve function itself by correcting the annulus.

[0151] Wireless sensor 200c is connected to one end of the annuloplasty ring via connector 300c. Connector 300c is an open-loop cannula, specifically, one with an axially defined opening 330c on its sidewall and a receiving cavity 321c. One end of the cannula is sleeved onto a terminal segment 231c of wireless sensor 200c, while the other end is sleeved onto one end of treatment device 100c.

[0152] Specifically, the connector 300c can be made of either a metal or a polymer material. The diameter of the accommodating cavity 321c of the connector 300c can be slightly smaller than the outer diameter of the housing 230c and the treatment device 100c, allowing for a tight fit between the two through an interference fit. Alternatively, the connector 300c can be a heat shrink tubing, tightly connected to the housing 230c and the treatment device 100c through a heat shrink process. Furthermore, the connector 300c, the treatment device 100c, and the housing 230c can be reinforced by bonding. When the connector 300c is made of metal, the opening is positioned to correspond to the wireless signal transmission element in the wireless sensor 200c. In some optional embodiments, the connector 300c may also be a complete sleeve without an opening, which surrounds the end section 231c of the shell 230c. The connector 300c may be made of a metal material or a polymer material. When the connector 300c is made of a metal material, the wireless signal transmission element in the wireless sensor 200c is not arranged in the end section 231c, that is, it is staggered with the connector 300c, so the connector 300c will not hinder the transmission of the wireless signal.

[0153] Referring to FIG11 , FIG11 is a schematic diagram of the structure of a wireless sensor implant according to another embodiment of the present disclosure. In this embodiment, the treatment device 100d is an annuloplasty ring. The wireless sensor 200d is connected to one end of the annuloplasty ring via a connector 300d. A connection hole is provided on the end surface of the housing 230d of the wireless sensor 200d. The connector 300d includes a sleeve portion 310d and a plug portion 322d, which are coaxially arranged. The sleeve portion 310d is sleeved on one end of the treatment device 100d. The plug portion 322d is inserted into the connection hole at the end of the housing 230d and is fixed by glue, a threaded structure, or a welding process. In some optional embodiments, the connector 300d includes only the plug portion 322d, one end of which is plugged into the housing 230d and the other end is inserted into the treatment device.

[0154] Refer to Figures 12 to 14. Figure 12 is a structural schematic diagram of an implant and its application scenario according to another embodiment of the present disclosure. Figure 13 is an enlarged schematic diagram of the implant in Figure 12. Figure 14 is an assembly schematic diagram of the therapeutic device and the sensor in the implant. In this embodiment, the therapeutic device 100e is a left atrial appendage occluder. The connector 300e is a sleeve with one end closed, and the accommodating cavity 321e of the sleeve accommodates the shell 230e of the wireless sensor 200e. The left atrial appendage occluder is generally disc-shaped, with a cup-shaped connecting structure provided at the center. The shell 230e of the wireless sensor and the connector 300e are inserted into the connecting structure of the left atrial appendage occluder. The connector 300e can be formed by curing glue, which firmly connects the therapeutic device 100e and the shell 230e of the wireless sensor together. The wireless signal transmission element in the wireless sensor 200e is staggered with the cup-shaped connecting structure of the therapeutic device 100e. In some optional embodiments, the connector 300e may also be a structure as shown in FIG10 or FIG11 , and a rod-shaped connecting structure is provided at the center of the left atrial appendage occluder, which can also connect the left atrial appendage occluder to the wireless sensor.

[0155] Refer to Figure 15, which is a schematic diagram of the structure of a wireless sensor in an implant according to another embodiment of the present disclosure. In this embodiment, wireless sensor 200f is a cylindrical structure, with a cylindrical housing 230f housing a detection element and a wireless signal transmission element. Connector 300f is a polymer heat-shrink tubing. The therapeutic device is a stent-type device, such as a vascular stent, shunt, or occluder. A first connecting wire 110f and a second connecting wire 120f can be extended from the stent-type device. The first connecting wire 110f and the second connecting wire 120f are inserted between the housing 230f and the heat-shrink tubing from the two edges of the tubing, respectively. When heated, the heat-shrink tubing shrinks, clamping the first and second connecting wires 110f, 120f. The first and second connecting wires 110f, 120f can be metal wires of a certain strength. This type of connection allows the wireless sensor 200f to be connected to the outer surface, inner surface, or end of the therapeutic device. In some optional embodiments, the connector 300f may also be a metal sleeve having an inner diameter that matches the outer diameter of the housing 230f. When the connector 300f is sleeved within the housing 230f, it may be axially offset from the wireless signal transmission components within the housing 230f to prevent shielding of the wireless signal. In other embodiments, the connector 300f may also be a non-enclosed metal sleeve, such as one having a longitudinal opening in the sleeve wall that axially corresponds to the wireless signal transmission components within the housing 230f to prevent shielding of the wireless signal.

[0156] Refer to Figure 16, which is a schematic diagram of the structure of a wireless sensor in an implant according to another embodiment of the present disclosure. In this embodiment, the housing 230g of the wireless sensor 200g is cylindrical and houses the detection element and wireless signal transmission element. The connector 300g comprises two arranged sleeves. The therapeutic device is a stent-type device, such as a vascular stent, shunt, or occluder. A filamentous structure can extend from the stent-type device to connect to the sleeve. In this embodiment, the filamentous structure is a first connecting wire 110g and a second connecting wire 120g, both of which are connected to the connector 300g. Specifically, the first connecting wire 110g and the second connecting wire 120g are inserted between the housing 230g and the sleeves, respectively, from the edges of the two sleeves. The first connecting wire 110g passes through the lower sleeve and extends from the middle to the lower end. The second connecting wire 120g passes under the upper sleeve and extends from the middle to the upper end. When the connector 300g is a heat shrink tubing, its initial diameter is larger than the diameter of the housing 230g. When the connecting piece 300g is a metal tube, it has an inner diameter that is adapted to the outer diameter of the housing 230g. In some optional embodiments, the filamentous structure can also be a U-shaped or V-shaped structure after bending. In some optional embodiments, the filamentous structure can also be a q-shaped structure or an inverted q-shaped structure after bending, that is, after passing through the sleeve, the end portion of the filamentous structure can be wound into a circle to prevent it from escaping from the sleeve. Furthermore, the end portions of the two filamentous structures that penetrate the sleeve from opposite directions can be clamped to each other to further prevent the filamentous structure from escaping from the sleeve. In some optional embodiments, a sheet structure can also be used to replace the connecting wire. The sheet structure has a smaller thickness and greater strength, which can improve the connection strength.

[0157] Refer to Figure 17, which is a schematic diagram of the structure of a wireless sensor in an implant according to another embodiment of the present disclosure. Wireless sensor 200h in this embodiment is substantially identical to wireless sensor 200f in Figure 15, except that it is provided with an opening 310h. The first and second connecting wires 110h, 120h are inserted into the sleeve from the opening 310h rather than from the edge of the sleeve, and extend toward both ends of wireless sensor 200h. When connector 300h is a heat shrink tubing, its initial diameter is greater than the diameter of housing 230h. When connector 300h is a metal tube, it has an inner diameter that matches the outer diameter of housing 230h.

[0158] Referring to Figure 18, Figure 18 is a schematic diagram of the structure of a wireless sensor in an implant according to another embodiment of the present disclosure. The housing 230i of the wireless sensor 200i is cylindrical. The connecting member is a sleeve formed by combining a first half shell 310i and a second half shell 320i, which is equivalent to a sleeve split longitudinally into two parts. A connecting hole 311i is provided on the longitudinal end surface of the first half shell 310i, and a corresponding positioning pin 321i is provided on the longitudinal end surface of the second half shell 320i. The first half shell 310i and the second half shell 320i are connected to form a single unit through the matching connecting hole 311i and the axial hole of the positioning pin 321i. The therapeutic device is a stent-type device, such as a vascular stent, shunt, or occluder. A first connecting wire 110i and a second connecting wire 120i can be extended from the stent-type device to connect to the wireless sensor 230i. The first connecting wire 110i and the second connecting wire 120i are pressed against the surface of the housing 230i by the first half shell 310i and the second half shell 320i respectively.

[0159] It can be understood that in the embodiments shown in Figures 15 to 18, the first connecting wire and the second connecting wire can be either a metal wire forming the stent-type device body or a filamentous structure cut from a metal tube, or other filamentous structures connected to the stent-type device body by welding, bonding, or the like, or can be replaced by a sheet-like structure. The first connecting wire and the second connecting wire can also be referred to as the first joining segment and the second joining segment. The stent-type device body can also include an elastic curved segment, which is connected to the first joining segment and the second joining segment.

In this embodiment, the therapeutic device 100j is a stent-type device, such as a vascular stent, a valve stent, a shunt, an occluder, etc. The stent-type device can be constructed by braiding or winding elastic wire or by cutting a tubular structure into a mesh tube. The housing 230j and the connector 300j are integrally formed. The connector 300j includes an insertion rod and a sleeve disposed on the surface of the housing 230j. The sleeve is mounted on the filamentary structure of the stent-type device, and the insertion rod is inserted between the filamentary structure and the sleeve. The sleeve can be made of either metal or polymer material. The insertion rod has a portion perpendicular to the housing 230j and a portion parallel to the housing 230j. The portion parallel to the housing 230j is spaced slightly apart from the housing surface and inserted into the sleeve.

The shell 230m is a cylindrical structure, which accommodates the detection element and the wireless signal transmission element. The connector 300m is a groove provided on the circumference of the shell 230m, and the groove is used to form a mortise and tenon structure with the corresponding protrusion of the treatment device. The mortise and tenon structure refers to a connection formed by "convex-concave matching". The treatment device can be a stent-type device, such as a vascular stent, a valve stent, a shunt, an occluder, etc., and the groove can be directly connected to the wire of the stent. Alternatively, the treatment device can also be specially provided with a male head structure (such as a pin), which is plugged into the groove of the shell 230m through the male head structure.

[0163] Referring to FIG. 23 , FIG. 23 is a schematic diagram of the structure of an implantable wireless sensor according to another embodiment of the present disclosure. In this embodiment, the housing 230n of the wireless sensor is integrally formed with the connector 300n and is made of a non-metallic material. The housing 230n is a cylindrical structure that houses the detection element and the wireless signal transmission element. The end surface of one end is provided with a threaded hole, and the end with the threaded hole is the connector 300n. A corresponding external thread structure can be provided on the treatment device to connect to the connector 300n. The treatment device can specifically be an occluder, an annuloplasty ring, or other device. Threaded rods can be provided at the center of the occluder and at the end of the annuloplasty ring to secure the connector 300n.

[0164] Refer to Figure 24, which is a structural diagram of a wireless sensor of an implant according to another embodiment of the present disclosure. In this embodiment, the shell 230p is a cylindrical structure, which accommodates the detection element and the wireless signal transmission element. The therapeutic device can be a leadless pacemaker, and can also be accommodated in the shell 230p, which is equivalent to the shell 230p being used as a connector at the same time. A connecting spring 300p is provided at one end of the shell 230p, which is coaxially arranged at the end of the shell 230p. The connecting spring can be anchored to the affected area. In some optional embodiments, the connecting spring 300p is the connecting member, and the therapeutic device is not provided inside the shell 230p. The sensor is connected to the therapeutic device through the connecting spring 300p.

[0165] Refer to Figures 25 and 26. Figure 25 is a structural schematic diagram of the shell of a wireless sensor according to another embodiment of the present disclosure. Figure 26 is a connection method between a wireless sensor having the shell shown in Figure 25 and a therapeutic device. In this embodiment, the shell 230v and the connector are formed integrally. Specifically, the connector is two annular grooves 231v provided on the outer peripheral surface of the shell 230b. The therapeutic device is a stent-type device, such as a heart stent formed by braiding metal wires. Two connecting wires can be led out of the stent-type device and clamped in the two annular grooves 231v of the shell 230v, so that the wireless sensor is arranged side by side on the outside or inside of the therapeutic device. The therapeutic device in Figure 26 can be an interatrial shunt.

[0167] In this embodiment, the connector of the wireless sensor 200w is integrally formed with the housing 230w and is made of a non-metallic material. The housing 230w is a cylindrical shell that houses the detection element and the wireless signal transmission element. The connector is at least one through-hole 231w provided in the wall of the housing 230w, parallel to the axial direction. Preferably, the connector is two through-holes 231w provided in the wall of the housing 230w, parallel to the axial direction. The therapeutic device is a stent-type device, such as a vascular stent, an interatrial shunt stent, or a hemangioma / dissection isolation stent formed of braided metal wire. In the embodiment shown in Figure 28, two connecting wires are extended from the stent-type device and passed through the through-holes 231w of the housing 230w, allowing the wireless sensor 200w and the therapeutic device to be tightly aligned side by side. In the embodiment shown in Figure 29, a single connecting wire is extended from the stent-type device. The connecting wire passes through one through-hole 231w, bends into a larger-diameter ring, then re-enters through the other through-hole 231w, and continues to bend as part of the stent. The wireless sensor 200w can be positioned at the end, center, interior surface, or exterior surface of the stent, depending on actual needs. This allows the wireless sensor 200w to be securely inserted into the main body of the stent-like device. In the embodiment shown in Figure 30 , the therapeutic device 100w is further provided with a reinforcing rib 110w. The reinforcing rib 110w extends through a through-hole 231w in the housing 230w to secure the wireless sensor 200w to the therapeutic device 100w.

[0168] It can be understood that in the embodiments shown in Figures 27 to 30, the connecting wire can be either a metal wire forming the stent-type device body or a filamentous structure cut from a metal tube, or other filamentous structures connected to the stent-type device body through welding, bonding, or other processes. The connecting wire can also be called a joining segment, and the stent-type device body can also include an elastic curve segment, which is connected to the joining segment.

Specifically, the connector 300q is a cannula, one end of which is positioned over the wireless sensor 200q and the other end is inserted into the main body of the valve clip, on the same side as the clips. In some alternative embodiments, the wireless sensor 200q can also be inserted into the other side of the main body of the valve clip, with the wireless sensor 200q and the clips located on opposite sides of the main body; alternatively, one end of the wireless sensor 200q can be positioned on one side of the main body of the valve clip, and the other end on the other side, to simultaneously sense both the atria and the ventricles.

[0170] Refer to Figures 33 and 34. Figure 33 is a schematic structural diagram of an implant and its application scenario according to another embodiment of the present disclosure.

The connector 300t is a sleeve, which clamps the artificial tendons to the surface of the wireless sensor 200t. The artificial tendons and the anchors 310t are distributed at both ends of the connector 300t. The anchor 310t is a spring anchored at the apex of the heart; the artificial tendons are fixed to the valve to pull the valve.

[0172] Refer to Figures 37 and 38. Figure 37 is a schematic diagram of the structure of an implant and its application scenario according to another embodiment of the present disclosure. Figure 38 is a schematic diagram of the structure of the implant in Figure 37. In this embodiment, the therapeutic device 100u is a leadless pacemaker, which is covered by a connector 300u. The leadless pacemaker is coaxially fixed to the wireless sensor 200u by the connector 300u. The entire implant is fixed to the heart via the leadless pacemaker's anchor hook 310u.

[0173] It can be understood that when the connectors 300r, 300t, 300u are made of metal material, the connectors 300r, 300t, 300u are open-loop sleeves or are axially staggered with the wireless signal transmission elements of the wireless sensors 200r, 200t, 200u.

[0174] Refer to Figure 39, which is a schematic structural diagram of an implant and its application scenario according to another embodiment of the present disclosure. In this embodiment, the therapeutic device 100v is a cardiac catheter pump assembly. The cardiac catheter pump assembly can be placed in the left ventricle to guide blood from the left ventricle to the ascending aorta. The cardiac catheter pump assembly is a short-term implant and includes a guidewire 110v, a catheter 120v, and a pump body 130v. The guidewire 110v and catheter 120v will also remain in the body for a period of time along with the pump body 130v. In this embodiment, the wireless sensor 200v can be placed on the guidewire 110v or catheter 120v. In this case, the connector can adopt the structure shown in Figure 27, with the guidewire 110v inserted into the through hole 231w of the housing 230w, or as shown in Figure 19, a sleeve can be placed on the catheter 120v, and the insertion rod can be inserted between the catheter 120v and the sleeve. When the wireless sensor 200v is placed on the catheter 120v, its position within the heart is the ascending aorta. When wireless sensor 200v is located on guidewire 110v, it is located in the left ventricle within the heart. Wireless sensor 200v can also be placed on the outer surface of pump body 130v. Because pump body 130v has a stent-like mesh structure, the connector can adopt any of the configurations shown in Figures 15 to 20 or Figures 25 to 27. In this case, it is located in the left ventricle within the heart.

[0175] In the following, for a better understanding of the present disclosure, an implant and an implant system are described by taking the application of the implant in cardiovascular system as an example.

[0176] Atrial shunt surgery is a procedure used to improve left atrial hypertension. Atrial septal puncture is performed to divert blood flow from the left atrium to the right atrium, thereby reducing the left atrial burden. Atrial shunt surgery can be divided into implantable and non-implantable shunts. Implantable shunts require an implant to be fixed within the artificially created atrial septal puncture to prevent the puncture from closing. Currently, atrial septal puncture and implant fixation are typically performed through vascular intervention.

[0177] In addition to the shunts suitable for patients with heart failure mentioned above, there are other stent-type implants suitable for placement in the heart or blood vessels for patients with cardiovascular diseases. For example, some patients need to place occluders in their hearts or blood vessels to improve cardiovascular function, and patients with vascular stenosis may need to implant vascular stents. However, in addition to treating related symptoms through implants, monitoring the hemodynamic parameters of the patient's cardiovascular system is also very meaningful. For example, for patients with heart failure, in addition to surgical treatment, atrial pressure monitoring is also an important health management method. However, how to combine pressure monitoring devices with these stent-type implants is a major technical difficulty in this field. The applicant found that if the pressure monitoring device is installed in the stent, since the stent is usually a mesh structure made of woven metal wires or cut from pipes, the mesh structure will interfere with or even shield the wireless signal transmission of the pressure monitoring device. If the pressure monitoring device is axially arranged at the proximal or distal end of the stent, the pressure monitoring device will increase the length of the overall structure, hinder the normal flow of blood, affect the size of the stent port, and create the risk of long-term stenosis.

[0178] The present disclosure provides an implant for implantation in a living organism to improve the organism's physiological functions and simultaneously obtain target physiological parameters. The implant comprises a stent, a wireless sensor, and a connector. The stent is positioned at a target site to improve the organism's physiological functions. The stent can be a mesh structure such as a shunt, occluder, or vascular stent. The stent comprises at least a main body formed by multiple elastic curved segments. "Elastic curved segments" herein refer to elastic, generally curved segments of wire, but localized regions of the "elastic curved segments" may still exhibit a straight shape. Multiple elastic curved segments can also be formed from the same wire or from multiple different wires, such as braided metal wire, though this application is not limited thereto. The wireless sensor comprises an electrically connected detection element and a wireless signal transmission element. The detection element is used to obtain the target physiological parameters. The wireless signal transmission element is used to transmit the target physiological parameters obtained by the detection element to the outside of the organism. The connector connects the wireless sensor to the stent, allowing the wireless sensor to be positioned outside the stent and in contact with the outer circumference of the stent. With such an arrangement, the bracket will not affect the signal transmission of the wireless sensor, and the wireless sensor will not affect the port size at both ends of the bracket. In particular, when the bracket is a diverter, the diversion capacity of the bracket will not be affected.

[0179] The stent can be fixed to the wireless sensor by various means such as crimping, bonding, suturing, welding, etc. In this embodiment, the stent and the wireless sensor are fixed by a specially designed connector, which includes a first connector and a second connector that are connected to each other, the first connector is connected to the wireless sensor, and the second connector is connected to the elastic curve segment of the stent. Specifically, the stent also includes at least one joining segment, which is arranged in a predetermined area of ​​the main body and is connected to a part of at least one of the elastic curve segments. The joining segment is inserted into the second connecting portion so that the connector is attached to the stent in a predetermined area (for example, the surface of the stent, preferably the outer peripheral surface of the stent). The wireless sensor is maintained at the periphery of the stent by the connector and is arranged roughly side by side with the stent. The wireless sensor is fixed to the surface of the stent by cooperating with the connector connected to the elastic curve segment. The connection structure is simple, reliable and compact, and the elastic curve segment itself is part of the stent. There is no need to set up other structures to connect with the connector, which will not significantly increase the radial size of the implant and further reduce the risk of thrombosis.

[0180] Figure 40 is a schematic structural diagram of a target site m1 in a living organism according to an embodiment of the present disclosure. Specifically, the target site m1 is a hole in the atrial septum m2 between the left and right atria. This hole can be an unsealed foramen ovale or an artificially created hole. For some patients with heart failure, this hole can reduce left atrial pressure and alleviate heart failure symptoms. The stent provided in this embodiment of the present disclosure is a shunt. The shunt can be positioned within the hole to maintain the shape of the hole and guide blood flow from the left atrium to the right atrium. Preferably, the wireless sensor is positioned in the middle of the outer circumference of the shunt. Therefore, when the implant in this embodiment is positioned on the atrial septum m2, the wireless sensor and the stent are positioned together within the target site m1 and in contact with the target site. Furthermore, two detection elements can be positioned at each end of the wireless sensor to simultaneously measure pressure in the left and right atria. It should be noted that the wireless sensor can also be positioned at other suitable locations on the shunt, depending on the specific application scenario, as long as it does not affect signal transmission.

[0181] Referring to Figures 41 to 44, Figures 41 to 44 are schematic diagrams of the structure of an implant according to an embodiment of the present disclosure. In this embodiment, the implant includes a stent 100 and a wireless sensor 200. Figure 41 is a schematic diagram of the structure of an implant according to an embodiment of the present disclosure. Figure 42 is a schematic diagram of the structure of the implant in Figure 41 without the wireless sensor 200. Figure 43 is a partially enlarged schematic diagram of the connection between the connector 300 and the stent 100 in Figure 41. Figure 44 is a front view of the end face of the implant in Figure 40.

[0182] The implant includes a stent 100, a wireless sensor 200 and a connector 300. The stent 100 and the wireless sensor 200 are arranged side by side, and the connector 300 connects the two into one. It should be understood that the "side by side arrangement" in the present application is not limited to a parallel arrangement, and the stent 100 and the wireless sensor can also form a predetermined angle (but not perpendicular to each other). Of course, preferably, the stent 100 and the wireless sensor 200 are arranged in parallel, and as shown in Figure 44, when the main body of the stent is a cylindrical structure and the wireless sensor 200 is also a cylindrical structure, under the action of the coupling section and the connector, the wireless sensor 200 and the stent 100 present an circumscribed shape. Such a design can make the implant have a smaller radial dimension during the transportation process, which is convenient for being pressed and gripped in the transportation device.

[0183] In this embodiment, the stent 100 includes a main body 110, a first clamping arm 112, a second clamping arm 113, and a coating 120. The main body 110 is a tubular structure woven from metal wires and is generally cylindrical. The coating 120 is applied to the inner and / or outer surface of the main body 110. The first clamping arm 112 and the second clamping arm 113 extend radially outward from the surface of the main body 110 to form a cantilever structure. The first clamping arm 112 and the second clamping arm 113 form at least one clamping arm group, which are used to be distributed on both sides of the atrial septum m2 to clamp the atrial septum m2. The main body 110, the first clamping arm 112, and the second clamping arm 113 are all formed by winding and bending the elastic curved segment 101. Specifically, the main body 110 is divided into an upper tube and a lower tube. The number of the first clamping arm 112 and the second clamping arm 113 are both three. The three first clamping arms 112 are evenly distributed on the surface of the upper tube. The three second clamping arms 113 are evenly distributed on the surface of the lower cylinder. Part of the elastic curved section 101 extends in a wave-like manner in the axial direction and simultaneously extends in the circumferential direction to form a mesh cylinder; another part of the elastic curved section 101 extends radially outward from the surface of the mesh cylinder and then folds back to the cylinder surface to form a U-shaped clamping arm.

[0184] In some alternative embodiments, the main body 110 can also be cut from metal. The number of the first clamping arms 112 and the second clamping arms 113 can also be greater than or less than three, for example, two, as long as the clamping function can be achieved. The elastic curved segment 101 can also take other forms, which are not limited by this application.

[0185] Furthermore, the three first clamping arms 112 and the three second clamping arms 113 form three clamping arm groups. The first clamping arm 112 and the second clamping arm 113 of each clamping arm group are spaced apart in the axial direction. The first clamping arm 112 is spaced apart from the first end (the upper end in FIG. 41 ) of the main body 110 by a predetermined distance. The second clamping arm 113 is spaced apart from the second end (the lower end in FIG. 41 ) of the main body 110 by a predetermined distance. The free ends of the first clamping arm 112 and the second clamping arm 113 overlap in axial projection, while the fixed ends of the first clamping arm 112 and the second clamping arm 113 are staggered in axial projection, thereby achieving a larger clamping area (the area of ​​the clamping region formed by the first clamping arm 112 and the second clamping arm 113) and obtaining a better clamping effect. The fixed ends of the first clamping arm 112 and the second clamping arm 113 are the ends at which the first clamping arm 112 and the second clamping arm 113 are connected to the main body 110. The upper tube and the lower tube are coaxially distributed, and the two can be connected by a coating 120 and / or an elastic curve segment. The elastic curve segment of the lower tube extends in a circular form in the circumferential direction in the initial stage, and extends upward in a spiral form after one circle. The elastic curve segment of the upper tube extends upward in a spiral form in the circumferential direction in the initial stage, and extends in a circular form in the last circle. In the above embodiment, the axial distance of the clamping arm is 3mm. The optional range of the axial distance is greater than 0mm and less than or equal to 3mm. In the above embodiment, the elastic metal wire constituting the clamping arm and the elastic metal wire of the cylinder to which the base of the clamping arm is attached are the same elastic metal wire. In some optional embodiments, the clamping arm can be a separate U-shaped or V-shaped part, which is welded to the elastic curve segment of the cylinder by welding.

[0186] The clamping arm design in this embodiment is different from the waist-shaped or flange-shaped anchoring design in the prior art. It can effectively reduce the volume of the shunt device in the cavity and the contact area with the anchor point to avoid adverse effects on blood flow, and can firmly anchor the main body in the target area.

[0187] In this embodiment, the length of the coating 120 is equal to the sum of the lengths of the upper and lower tubes. Since the coating 120 is a cylindrical structure with a certain strength, its application to the inner and outer surfaces of the main body 110 can also strengthen the main body 110 and the connection between the upper and lower tubes. It also maintains the preset shape of the elastic curve segment, thereby preserving the shape of the main body 110. The coating 120 smoothes the inner lumen of the tube, preventing atrial septal tissue hyperplasia from blocking the lumen and maintaining a clear lumen. The coating 120 can be made of a polymer or biomaterial, including but not limited to polyester, polytetrafluoroethylene, or animal pericardium. The surface of the coating 120 can be coated to improve surface smoothness and enhance long-term patency. In some alternative embodiments, the coating 120 can also be applied to the outer surface of the main body 110. In other alternative embodiments, the coating 120 can be applied to both the inner and outer surfaces of the main body 110. Another beneficial effect of the coating 120 is its insulation, which can isolate the main body 110 from the wireless sensor 200 to a certain extent, preventing signal interference. The film 120 and the main body 110 can be connected by heat pressing or sewing. In order to more clearly distinguish the film 120 from the main body 110, the thickness of the film 120 is deliberately exaggerated and the film 120 is drawn on the inner surface of the main body 110. The actual thickness is smaller than the illustrated size.

[0188] Those skilled in the art will appreciate that, although in this embodiment, the bracket 100 and the wireless sensor 200 are connected via the connector 300 , in other embodiments, the bracket 100 may also be used as an independent diverter.

[0189] In this embodiment, the joining section includes a first joining section and a second joining section, each integrally formed with a portion of the two elastic curved sections. In other words, the first joining section is formed by a natural extension of a portion of the elastic curved section, and the second joining section is formed by a natural extension of a portion of the other elastic curved section. Referring to Figures 42 and 43 , in the middle portion of the main body 110, the initial section (upper portion) of the elastic curved section of the lower tube forms the first joining section 114, and the terminal section (lower portion) of the elastic curved section of the upper tube forms the second joining section 115.

[0190] Please refer to Figure 41. The wireless sensor 200 includes a detection element 210 and a wireless signal transmission element 220. The detection element 210 can be a pressure detection element that can measure, for example, the pressure of blood flow. The detection element 210 is arranged at one end of the wireless sensor 200 to monitor the pressure of the left atrium. The wireless signal transmission element 220 is used to transmit the signal collected by the detection element 210 to the outside of the human body in the form of electromagnetic waves. The detection element 210 and the wireless signal transmission element 220 are encapsulated as a whole by a sealing structure (also referred to as a shell). In other embodiments, two detection elements 210 can also be arranged at the two ends of the wireless sensor 200 to detect the pressure of the left atrium and the right atrium, and the wireless signal transmission element 220 is arranged between the two detection elements 210.

[0191] Referring to Figures 42 and 43 , in this embodiment, the connector 300 is an annular sleeve. A portion of the annular sleeve slightly protrudes outward, forming a second connecting portion 320m. The remainder of the annular sleeve, excluding the second connecting portion 320m, forms the first connecting portion 310m. The outward protrusion of the second connecting portion 320m may be formed by the connector 300 pulling the bracket 100 and wireless sensor 200 together, or it may be a permanent protrusion applied during manufacturing. The first connecting portion 310m is disposed around the center of the wireless sensor 200. The second connecting portion 320m is an overall thin sheet structure, comprising a sheet portion 321. The sheet portion 321 is generally rectangular. The sheet portion 321 has two parallel edges: an upper edge and a lower edge, perpendicular to the axis of the annular sleeve. The upper edge and at least a portion of the adjacent area form an edge portion 322, while the lower edge and at least a portion of the adjacent area form another edge portion 322. The two edge portions 322 are used to be clamped by the first engaging segment 114 and the second engaging segment 115 , that is, the two edge portions 322 form a clamped portion 323 .

[0192] In this embodiment, the width (axial dimension) of the annular sleeve is small, while the first and second engaging segments 114, 115 are long. Therefore, the first and second engaging segments 114, 115 each clamp two edge portions 322, that is, the first and second engaging segments 114, 115 clamp the entire axial area of ​​the sheet portion 321. In some alternative embodiments, the axial dimension of the sheet portion 321 is larger, and / or the first and / or second engaging segments 114, 115 are shorter, so that the first engaging segment 114 can only clamp the edge portion 322 corresponding to the lower edge, while the second engaging segment 115 only clamps the edge portion 322 corresponding to the upper edge. Relative to the overall size of the connector, the height of the protrusion of the second connecting portion 320m is very small. In some alternative embodiments, the first connecting portion can also be a complete cylindrical structure, and the second connecting portion 320m can be considered to be arranged to fit the outer contour of the first connecting portion 310m, so that the radial dimensions of the second connecting portion 320m and the first connecting portion 310m are not significantly increased. The so-called fitting here can be that the two adjacent surfaces are in contact with each other (but can be separated by external force, such as being separated by the insertion of the joining segment), or that the two adjacent surfaces have a small distance, thereby allowing the first joining segment to be inserted.

[0193] Through this connection method, the second connecting portion 320m of the connector 300 is clamped between the first and second connecting segments 114, 115, and the coating 120, effectively pressing the second connecting portion 320m against the surface of the main body 110. The stent 100 and the wireless sensor 200 are connected together in a parallel and circumferential manner. Furthermore, the first and second connecting segments 114, 115 are also clamped between the wireless sensor 200 and the second connecting portion 320m. This connection is simple and reliable, facilitating the assembly and connection of small components such as shunts. Furthermore, the free ends of the first and second connecting segments 114, 115 point in opposite directions, further preventing the second connecting portion 320m from axially dislodging. This connection method, in which the connecting segments on the surface of the stent 100 clamp the sheet structure on the surface of the wireless sensor 200, results in a very small radial dimension, allowing for a tight connection between the wireless sensor 200 and the stent 100 without causing the overall radial dimensions of the implant to be excessively large.

[0194] The shape of the connector 300 is not limited to that described in the aforementioned embodiment, as long as the first connector 310m is capable of fixedly connecting to the wireless sensor 200, the second connector 320m is disposed in contact with the surface of the first connector 310m, and can be clamped by the joint section of the main body 110. Therefore, the first connector 310m can also be a ring-shaped structure with an opening that can enclose the wireless sensor 200; or a closed or open box-shaped structure that matches the shape of the wireless sensor 200 and can accommodate the wireless sensor 200; or a structure that is adapted to fit the connected portion of the wireless sensor 200, such as a snap-fit, threaded, or adhesive surface structure (of course, the wireless sensor itself must be provided with a corresponding slot, threaded, or adhesive surface structure); and the second connector 320m can be an arched structure or a cantilever structure that can be clamped by the joint section.

[0195] Preferably, the connector 300 is a sleeve, a portion of which is the first connecting portion and the other portion is the second connecting portion. When the connector 300 and the wireless signal transmission element 220 at least partially overlap in the axial direction, the connector 300 is a non-metallic sleeve, and the cross-section of the non-metallic sleeve is a closed structure (for example, an O-shaped structure) or an open structure (for example, a C-shaped structure). In this way, the connector 300 itself can be prevented from affecting signal transmission; or the annular sleeve is a metal sleeve, and the cross-section of the metal sleeve is an open structure, which can also prevent the connector 300 itself from affecting signal transmission. When the connector 300 and the wireless signal transmission element 220 do not overlap at all in the axial direction, there is no restriction on the material of the connector 300.

[0196] Refer to Figure 50, which shows the implant installed at the target site. Target site m1 is the hole connecting the left and right atria. The implant is fully inserted into the hole and clamped to the atrial septal tissue by first and second clamping arms 112, 113 to prevent the implant from axially dislodging from target site m1. Sensing element 210 is located in the left atrium and is capable of detecting blood pressure within the left atrium. When the left atrium contracts, blood flows not only into the left ventricle but also partially into the right atrium through the lumen of stent 100. Wireless sensors 200 are positioned side by side on the exterior of stent 100, thus not obstructing blood flow within the lumen or at either end of stent 100. Stent 100 does not surround wireless sensors 200, thus not hindering wireless signal transmission. Wireless sensors 200 can be installed side by side with stent 100 in the atrial septal hole, eliminating the excessive atrial space occupied by traditional axial serial placement. The connector 300 is tightly connected to the joint section of the stent 100, so that the stent 100 and the wireless sensor 200 are tightly against each other, which can not only enhance the connection strength between the two, but also reduce the radial size of the two, which is beneficial to the operation of transvascular interventional implantation.

[0197] Refer to Figures 45 and 46. Figure 46 is a schematic diagram of the implant according to the aforementioned embodiment in a compressed state within a delivery tube. Figure 47 is a schematic cross-sectional view of the delivery tube and implant shown in Figure 46. The implant's support 100 is formed from elastic curved segments 101, allowing it to deform under external compressive force and return to its original shape upon removal of the force. The implant and the delivery tube used in interventional surgery form an implant system.

[0198] In the implant, the elastic curved segment forms the main body of the stent 100, giving the stent 100 its overall elasticity. When pressure is applied to the stent 100 from the wireless sensor 200 along the line connecting their centers, the stent 100 is compressed. Specifically, the stent 100 is resiliently deformed in a first radial direction within the confined space (the radial dimension in the direction of the applied force decreases, while the radial dimension perpendicular to the direction of the applied force increases; the "first radial direction" herein refers to the radial direction aligned with the direction of the applied force). This allows the wireless sensor 200 to partially embed within the recessed area of ​​the stent 100. Once the external force is removed, the stent 100 returns to its original shape and resumes its positional relationship with the wireless sensor 200. During the placement of the implant into delivery tube 400, the walls of delivery tube 400 exert pressure on stent 100 and wireless sensor 200 both along and perpendicular to the line connecting the centers of wireless sensor 200 and stent 100. This compresses stent 100 along a first radial direction into a C-shaped cross-section, while wireless sensor 200 partially embeds within a recessed portion of stent 100. Furthermore, first clamping arm 112 and second clamping arm 113 are compressed along the longitudinal section to align with the surface of stent 100, with the free ends of first clamping arm 112 and second clamping arm 113 converging toward the ends of stent 100. After placement into delivery tube 400, the implant's overall radial dimensions are compressed. This compression deformation occurs by flattening the cylindrical body, while maintaining its circumference. This radial dimension reduction, rather than through axial elongation, results in no significant change in the implant's axial dimensions. A shorter implant facilitates bending of delivery tube 400, facilitating easier implantation.

[0199] Referring to Figures 47 to 49 , the surgical procedure for implanting a shunt at a target site via an interventional catheter is illustrated. Figure 47 is a schematic diagram of a delivery tube 400 containing an implant reaching the target site m1. Figure 48 is a schematic diagram of an implant extending from one end of the delivery tube 400 and the first clamping arm 112. Figure 49 is a schematic diagram of the delivery tube 400 being withdrawn so that the first clamping arm 112 of the implant reaches the surface of the atrial septum m2. Figure 50 is a schematic diagram of the delivery tube 400 being removed so that the implant is installed at the target site m1.

[0200] One end of the delivery tube 400 containing the implant enters the right atrium through a larger blood vessel in the human body and enters the left atrium through the hole in the atrial septum m2. At this point, the implant is extended from the end of the delivery tube 400 by withdrawing the delivery tube or pushing the implant outward, allowing the first clamping arm 112 to expand into a cantilevered position. After the first clamping arm 112 is expanded, the implant's overall radial dimension is larger than the diameter of the hole in the atrial septum m2. The delivery tube is further withdrawn, and the implant moves with it until the first clamping arm 112 contacts the atrial septum m2. Further withdrawal of the delivery tube 400 will cause the implant to remain in this position due to the obstruction of the atrial septum m2 and will not be withdrawn with the delivery tube 400. Once the implant is completely free of the delivery tube 400, the second clamping arm 113 will also expand. The second clamping arm 113 and the first clamping arm 112 will hold the stent 100 and wireless sensor 200 in the hole in the atrial septum m2. The stent 100 radially returns to its original shape, and its lumen allows blood flow from the left atrium to enter the right atrium. After the stent 100 is in place, the detection element 210 of the wireless sensor 200 can monitor the blood pressure of the left atrium in real time and transmit the relevant information to an external receiving device via the wireless signal transmission element 220.

[0201] Refer to Figures 51 to 54. Figure 51 is a schematic structural diagram of an implant according to another embodiment of the present disclosure. Figure 52 is a view of the implant in Figure 51 from another angle. Figure 53 is an enlarged view of the connection structure between the connector and the coupling section in Figure 51. Figure 54 is a schematic structural diagram of the main body of the implant in Figure 51. The implant in this embodiment has basically the same structure as the implant in the aforementioned embodiment, such as the first clamping arm 112a, the second clamping arm 113a and the coating are the same in structure as the first clamping arm 112, the second clamping arm 113 and the coating 120. The main difference between the two is the structure of the connector and the structure of the corresponding coupling section on the main body. In order to facilitate the explanation of the structure of the connector, the sensor is hidden in the schematic diagram of this embodiment.

[0202] In this embodiment, the elastic curved segment 101a extends circumferentially and axially to form the main body of the stent 100a. The elastic curved segment is wavy in shape and includes multiple wave segments 102a. A trough 114a of one wave segment 102a in the middle of the stent 100a forms a first joining section, while a crest 115a of another wave segment 102a in the middle of the stent 100a forms a second joining section. The troughs 114a and crests 115a provide a larger area in the axial and circumferential directions, providing greater strength and clamping force, resulting in a more stable connection.

[0203] The connecting member 300ma is an annular sleeve with two through ends. The width (axial dimension) of the annular sleeve in this embodiment is greater than that of the annular sleeve in the embodiment shown in Figure 41. The annular sleeve comprises two parts: one is a sleeve with a semi-open cross-section and a two-thirds ring shape, which forms the first connecting portion 310ma; the other is a sleeve with a semi-open cross-section and a roughly rectangular shape, which forms the second connecting portion 320ma. Of course, in other embodiments, a diaphragm can be provided at the junction of the two to divide the sleeve into two chambers. The first connecting portion 310ma is disposed around the wireless sensor. The second connecting portion 320ma is used to be clamped by the first connecting segment 114a (trough) and the second connecting segment 115a (peak). The second connecting portion 320ma is a roughly rectangular thin film sheet, which is pressed against the surface of the main body 100a by the first connecting segment 114a (trough) and the second connecting segment 115a (peak). The second connecting portion 320ma can also be further bonded or sewn to the covering film 120a to strengthen the connection strength.

[0204] Refer to Figure 55, which is a schematic diagram of the structure of the connector 300mb and the joint segment 114b in an implant according to another embodiment of the present disclosure. To more clearly illustrate the connection between the connector and the joint segment, this embodiment only illustrates the sensor 200mb, the connector 300mb, and a portion of the elastic curved segment in the stent; other structures are omitted. The connector 300mb is an annular sleeve formed from a polymer material. The upper and lower edges of a portion of the annular sleeve, as well as the area between them, form a clamped portion, which in this embodiment is the second connecting portion. The other portion of the annular sleeve is the first connecting portion, which is fixed around the middle of the sensor 200mb. The joint segment 114b in the stent is an inverted V-shaped structure formed by bending the elastic curved segment. It is inserted between the second connecting portion and the sensor 200mb from the lower edge of the second connecting portion. The length of the joint segment 114b is greater than the axial dimension of the connector 300mb, so one end of the joint segment 114b extends from between the connector 300mb and the sensor 200mb.

[0205] Referring to Figure 56, the structure of the sensor 200mb, connector 300mb and coupling segment 114b shown in Figure 56 is basically the same as the structure shown in Figure 16, except that the top and two base ends of the coupling segment 114b are sutured to the membrane of the diverter bracket through the suture structure 600 (not shown in the figure).

[0206] Referring to Figure 57, Figure 57 is a schematic diagram of the structure of the connector and the joint section in an implant according to another embodiment of the present disclosure. In this embodiment, the sensor 200mc is clamped by the connector 300mc, and the connector 300mc is connected to the first joint section 114c and the second joint section 115c. Specifically, two slit-shaped openings 324c are provided on the second connecting portion of the connector 300mc, and the two openings 324c are parallel to the edges of the connector 300mc and have a predetermined distance in the axial direction. The first joint section 114c is a trough portion, and the second joint section 115c is a crest portion, and the two are arranged opposite to each other. The first joint section 114c and the second joint section 115c are inserted between the connector 300mc and the sensor 200mc through the two openings 324c. The respective edges of the two openings 324c and the area therebetween are the clamped portions.

[0207] Referring to Figure 58, Figure 58 is a schematic diagram of the structure of the connector and joint section in an implant according to another embodiment of the present disclosure. The sensor 200md and connector 300md in this embodiment are identical to the corresponding structures shown in Figure 56, except that the first joint section 114d and the second joint section 115d are different. The first and second joint sections 114d, 115d in this embodiment are similar in structure to the joint section shown in Figure 42, but unlike the joint section of a single rod, in this embodiment, the elastic curved section is disconnected at the wavy section, and the ends of the elastic curved section extend and fold back along its length to form a U-shaped joint section. Furthermore, the first and second joint sections 114d, 114d formed by the two folded ends overlap in the length direction and are radially embedded in each other. The specific manufacturing process can be to bend two metal wires separately and then interlock them together, or to provide a detour section on the same metal wire during the winding process, and then cut or remove a section of the detour section in the middle to form two U-shaped joint sections.

[0208] Refer to Figure 59, which is a schematic diagram of the structure of the connector 300md and the joint segment in an alternative embodiment. The connection method shown in Figure 59 is similar to the connection method shown in Figure 58, except that the first and second joint segments 114d, 115d are inserted between the connector 300md and the sensor 200md, rather than from the edge of the connector 300md. Instead, they are inserted through two openings 324d provided in the connector 300md. Both openings 324d are rectangular and have a predetermined axial distance between them. In the connection method shown in Figure 58, the first and second joint segments 114d, 115d, covered by the connector 300md, cannot connect with the stent coating, resulting in a weakened stent at this location. By providing openings 324d in the connector 300md, the length of the first and second joint segments 114d, 115d covered by the connector 300md can be reduced, thereby leaving more area for the joint segments to connect with the coating and preventing significant weakening of the stent at this location. Furthermore, since the first and second joining segments 114d and 114d are U-shaped, they have a larger area to clamp the connector 300md, and the connection strength between them can be further improved. In some optional embodiments, the first and second joining segments 114d and 114d can be further connected to the connector 300md by adhesive.

[0209] Reference is made to Figure 60, which shows a schematic structural diagram of a connector 30 in an optional embodiment. The connector 30 includes a first connecting portion 31 and a second connecting portion 32. The structure of the connector 30 in this embodiment is basically the same as the structure of the connector 300 shown in Figure 41, except that its axial dimension is larger, so that it can completely surround the wireless sensor in the axial direction. This arrangement can make the surface of the implant smoother as a whole, reduce holes or gaps, and reduce the chance of thrombosis. Preferably, the connector 30 is made of a polymer material, which can not only prevent itself from affecting signal transmission, but also protect the wireless sensor, preventing the stent from damaging the wireless sensor during transportation.

[0210] In order to better connect the wireless sensor to the bracket, the connector in the above embodiments can be made of heat shrinkable material. After the connector is connected to the wireless sensor through the joint section, the joint section is firmly fixed between the connector and the wireless sensor through the heat shrink process, thereby achieving a stable connection between the wireless sensor and the bracket. In the above embodiments, the joint section and the elastic curve section are integrally formed as an example, but those skilled in the art will understand that in other embodiments of the present invention, the joint section can also be made of a material different from the elastic curve section, for example, the elastic curve section is a metal wire, the joint section is a hard plastic tube or a stainless steel sheet, etc., and the joint section and the elastic curve section are fixedly connected (for example, welded), which can also achieve the purpose of the invention of this application. However, from the convenience of the processing technology and the effect of use, the preferred method of integrally forming the joint section and the elastic curve section is not only simple, reliable and compact; and the elastic curve section itself is part of the bracket, and no additional structure is required to connect with the connector, which will not significantly increase the radial size of the implant, and can also completely avoid the safety issues caused by the connection firmness or smoothness of the additional joint section and the elastic curve section.

[0211] Referring to Figures 61a to 61e, some alternative embodiments of the stent are shown.

[0212] Figure 61a is a schematic diagram of the front profile shape of the bracket in an optional embodiment. In this embodiment, the diameter of the middle part of the bracket is smaller than the diameter of the two ends, forming an X-shaped front profile shape. Figure 61b is a schematic diagram of the front profile shape of the bracket in another optional embodiment. In this embodiment, the upper section of the bracket is trumpet-shaped, and the lower section is straight-cylindrical, forming a Y-shaped front profile shape. Figure 61c is a schematic diagram of the longitudinal cross-sectional projection shape of the bracket in another optional embodiment. In this embodiment, the diameter of one end of the bracket is larger than the diameter of the other end, and the diameter of the cylinder changes linearly in the axial direction, forming a V-shaped front profile shape. Figure 61d is a schematic diagram of the front profile shape of the bracket in another optional embodiment. In this embodiment, the diameter of the two ends of the bracket is different from the diameter of the middle part, and the centers of the two ends are not coaxial with the center of the middle part, and the bracket has a K-shaped front profile shape. Figure 61e is a schematic diagram of the front profile shape of the bracket in another optional embodiment. In this embodiment, the bracket is Z-shaped as a whole.

[0213] The present disclosure also provides an implant system. The implant system includes a delivery catheter and an implant. The delivery catheter is used to accommodate the compressed implant and deliver the implant to the target site through an artificial or natural chamber / pipeline. The implant may include a stent and a wireless sensor. The stent may be a shunt for atrial shunt surgery as described in the aforementioned embodiment, or an occluder or a vascular stent. The implant is in a compressed state within the delivery catheter. Specifically, the stent is compressed into a C-shaped cross-section, and the outer surface of the compressed stent at least partially surrounds the sensor, thereby reducing the diameter of the implant. When the delivery catheter delivers the implant to the target site, the implant can be pushed out of the catheter through the inner catheter.

[0214] In some optional embodiments, the implant system further includes a signal receiving device for receiving signals from wireless sensors in the implant, so as to allow medical personnel to track changes in physiological parameters of the organism in real time.

[0215] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
