Description

Technical Field

[0001] The present disclosure relates to the technical field of interventional medical devices, and in particular, to an implant with a wireless sensor. 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 vascular diseases. For example, some patients need to have occluders placed in their hearts or blood vessels to improve cardiovascular function, and some patients with vascular diseases need to have vascular stents implanted. 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 an important disease management tool. 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 the monitoring device with different types of therapeutic devices without generating new signal interference factors and significantly increasing the overall size during the combination process is a major technical difficulty in this field.

[0076] 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 a variety of ways and should not be construed as being limited to the embodiments described here. The embodiments described here are only for a more thorough and complete understanding of the present disclosure.

[0077] 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 “based on” means “at least in part based on.”

[0078] 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.

[0079] The disclosed embodiment provides an implant for implantation into a target part in a living body. The implant includes a therapeutic device and a wireless sensor. The therapeutic device is used to be arranged at the target part to improve the physiological function of the living body; the wireless sensor includes a detection element, a wireless signal transmission element, a shell and a connector, which are used to monitor the target physiological parameters in the living body. The detection element and the wireless signal transmission element are arranged in the shell; the detection element is used to obtain the 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 shell 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 shell. 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, so as to prevent 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 the present invention does not limit this; the "signal transmission path" referred to in the present invention 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.

[0080] 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 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 it will not block or shield the signal transmission path. The electromagnetic shielding structure refers to a closed metal cover, metal cage or other structure that can shield electromagnetic signals. The non-electromagnetic shielding structure does not include the above structure and will not shield electromagnetic signals. In this way, the implant can achieve both therapeutic and diagnostic effects, and can make the signal of the wireless sensor unaffected by the implant or connector, thereby achieving more accurate signal transmission.

[0081] refer to Figure 1 and Figure 2 . Figure 1It is a schematic diagram of an implant and its application scenario according to an embodiment of the present disclosure. Figure 2 yes Figure 1 Schematic diagram of the structure of the wireless sensor 200 implanted in the present invention. The implant includes a treatment device 100 and a wireless sensor 200. The wireless sensor 200 can be mounted 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 related 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, temperature, etc.

[0082] The treatment device 100 is a mesh-tube-shaped stent having an expanded diameter section and a non-expanded diameter section, wherein the diameter of the expanded diameter section is larger than that of 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 .

[0083] The wireless sensor 200 includes a detection element 210, a wireless signal transmission element 220, a housing 230 and a connector 300. 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 to the outside of the human body. 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. The housing 230 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 for connecting with the connector 300.

[0084] The connecting member 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 peripheral surface of the hoop 320 and extends parallel to the axial direction of the hoop 320. The connecting member 300 is sleeved on the matching structure 231 of the housing 230 through the hoop 320, and the connecting member 300 is fixed to the bottom of the treatment device 100 through the hooking rod 310, so as to connect the wireless sensor 200 with the treatment device 100. Specifically, the end of the hooking rod 310 can be welded to the grid of the treatment device 100, or connected by crimping, bonding, etc., or can be integrally formed with at least a portion of the treatment device 100. In some optional embodiments, the hooking rod 310 can also be other structures, such as connecting structures such as anchor hooks, sleeves, and plugs, and the corresponding connecting structure can be selected according to different treatment devices.

[0085] In this embodiment, the connector 300 is a metal part, so the treatment device 100 and the wireless sensor 200 can be firmly connected. The hoop 320 of the connector 300 is a thin-walled open-loop sleeve, which is not closed in the circumferential direction (equivalent to providing a longitudinal opening on the sleeve wall), so it will not shield electromagnetic signals, and will not significantly increase the radial size when connected to the shell 230. In addition, the shell 230 is provided with a corresponding matching structure 231 (annular groove) to accommodate the hoop 320, so that the outer peripheral surface of the wireless sensor 200 can be smooth as a whole, without bosses or grooves, and thrombosis can be prevented. In addition, the connection between the hoop and the annular groove also forms axial positioning, which strengthens the connection strength between the two. In other optional embodiments, the surface of the shell 230 may not be provided with an annular groove, and the entire outer peripheral surface or part of the outer peripheral surface of the shell 230 is a matching structure. The hoop 320 is directly sleeved on the entire outer circumference of the housing 230 or part of the outer circumference; further, the contact surface between the hoop 320 and the housing 230 can also be bonded to strengthen the connection strength. In other optional embodiments, the housing 230 and the connector 300 are integrally formed, which can further reduce the size and strengthen the strength, and also reduce the complexity of the assembly process. In addition, the hoop 320 is provided with an opening 330, so that the signal shielding of the wireless signal transmission element 220 will not be formed. In other optional embodiments, the hoop 320 is an open ring structure made of metal material and its axial length is consistent with the axial length of the housing 230. The hoop 320 is provided with an opening, and the axial length of the opening can be consistent with the axial length of the housing 230, or it can be less than the axial length of the housing 230 but greater than the axial length of the wireless signal transmission element 220, and the opening is set corresponding to the wireless signal transmission element 220 of the wireless sensor 200, thereby forming a wireless signal transmission window for wireless signal transmission.

[0086] 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 from 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, so 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 circumference 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 made here.

[0087] In some optional embodiments, the number of the hooking rods 310 can also be 2 or more, so that the connection strength between the connector 300 and the treatment device 100 is greater. In some optional embodiments, the connector 300 can also include an upper cover or a lower cover connected to the hoop 320, and the upper cover and / or the lower cover are sleeved on the end without the shell 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 rod 310, the hoop 320 and the mesh stent are integrally cut and formed, or the hooking rod 310, the hoop 320, the upper cover or the lower cover and the mesh stent are integrally cut and formed and the expanded mesh stent is formed through a diameter expansion process. In this way, the connection process of the treatment device 100 and the shell 230 can be further simplified, and the connection strength between the two can be enhanced.

[0088] 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 yes Figure 3 Schematic diagram of the structure of the wireless sensor from another perspective. Figure 5 yes Figure 3 A schematic structural diagram of another embodiment of a connector for an implant in the art. Figure 6 yes Figure 3 Schematic diagram of the structure of the shell of the wireless sensor.

[0089] In this embodiment, the connecting member 300a is made of metal material. The connecting member 300a includes a hanging rod 310a and two hoops 320a. An opening 330a is provided on the hoop 320a. The two hoops 320a have a predetermined distance in the axial direction. A part of the rod section of the hanging rod 310a connects the two hoops 320a in series. The wireless sensor 200a is a cylindrical structure, and the surface of its shell 230a is provided with two matching structures 231a. In this embodiment, the matching structure 231a is specifically an annular groove, and the axial spacing of the two annular grooves is equal to the axial spacing of the two hoops 320a. The two hoops 320a of the connecting member 300a are stuck in the two matching structures 231a of the shell 230a. Since the connecting member 300a and the shell 230a have two matching points in the axial direction, the connection between the two is more stable. The opening 330a on the hoop 320a makes the hoop an open ring structure, so it will not interfere with the wireless signal. In such as Figure 5 In the illustrated embodiment, a reinforcement hole 321a is further provided on the hoop 320a near the opening 330a. By inserting a reinforcement member, such as a suture, into the two reinforcement holes 321a, the connection strength between the connector 300a and the housing 230a can be further strengthened. In some optional embodiments, the surface of the housing 230a may not be provided with an annular groove, and the two hoop rings 320a may be directly sleeved on the circumferential surface of the housing 230a.

[0090] The wireless sensor 200a can be connected to the treatment device via the hook rod 310a. Figure 1 The valve stent shown in .

[0091] refer to Figure 7 and Figure 8 . Figure 7 is a schematic diagram of the structure of a wireless sensor implanted in another embodiment. Figure 8 yes Figure 7 Schematic diagram of the structure of the shell 230b of the wireless sensor 200b. In this embodiment, the part of the connector 300b used to connect the shell 230b of the wireless sensor 200b is a spiral structure 320b, and the part used to connect 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 belt. The surface of the shell 230b is provided with a matching structure 231b, specifically a spiral groove. The connector 300b is embedded in the spiral groove of the shell 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 belt, and there is no electromagnetic shielding structure (for example, a metal closed loop structure), which will not hinder the transmission of wireless signals, and the spiral structure 320b forms an open-loop cylindrical structure.

[0092] The wireless sensor 200b can be connected to the treatment device via the hook rod 310b. Figure 1 The valve stent shown in .

[0093] refer to Fig. 9 and Fig.10 . Fig. 9 An implant and its application scenario according to another embodiment of the present disclosure. Fig.10 yes Fig. 9 Schematic diagram of the structure of the wireless sensor in the figure. In this embodiment, the implant includes a treatment device 100c and a wireless sensor 200c. The treatment device 100c is an open valvuloplasty ring. The valvuloplasty ring shown in the figure is arranged between two valves between the left atrium and the left ventricle in the heart. Valvuloplasty mainly treats the symptoms of valvular insufficiency caused by valvular ring lesions or other heart diseases, and the valve function itself can be restored by correcting the valvular ring.

[0094] The wireless sensor 200c is connected to one end of the annuloplasty ring through a connector 300c. The connector 300c is an open-loop sleeve, that is, the sleeve has an opening 330c arranged on the side wall along the axial direction, and the sleeve has a receiving cavity 321c. One end of the sleeve is sleeved on a terminal section 231c of the wireless sensor 200c, and the other end is sleeved on one end of the treatment device 100c.
