Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a device and system for interventional implantable medical devices. Background Technology

[0002] Valvular annulus dilatation is the most common cause of mitral and tricuspid regurgitation. Valvular annulus reduction surgery, which is performed to treat mitral or tricuspid valve dilatation, is an important and basic surgical procedure for mitral or tricuspid valve repair. Its principle is to reduce the regurgitation caused by valve annulus dilatation by reducing the valve orifice area of ​​the mitral or tricuspid valve so that the leaflets can fit together, thereby reducing regurgitation or even completely eliminating regurgitation.

[0003] In related technologies, medical devices (such as organ repair components, anchors, or locking components) need to be implanted during tricuspid and mitral valve repair surgery. Existing devices for implanting medical devices are not only complex in structure, have many parts, occupy a large area, but also have low reliability and are prone to medical accidents. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a device and system that can improve the convenience and reliability of implanting medical devices.

[0005] In a first aspect, this application provides an apparatus for an interventional implantable medical device, comprising: a delivery member including a connecting end and a plurality of delivery bodies connected to the connecting end, the delivery bodies being provided with a slide for delivering the medical device, and the distal ends of the plurality of delivery bodies being adapted to be far apart from each other.

[0006] In the above scheme, the delivery device includes a connecting end and multiple delivery bodies connected to the connecting end. When the medical device is implanted, the connecting end is located on the side away from the organ relative to the delivery body. The multiple delivery bodies are spaced apart, and each delivery body is provided with a slide for transporting the medical device. This allows the medical device to be transported along the slide to a preset position in the organ tissue by the carrier, thereby completing the implantation of the medical device. The device for interventional implantation of medical devices provided in this application, after positioning the distal end of the delivery body with the organ tissue, transports multiple medical devices through the slides on the multiple delivery bodies. This eliminates the need for repeated installation and positioning, improves the efficiency of medical device delivery, reduces the risk of organ damage during medical device delivery, and effectively improves the safety and reliability of the medical device during the implantation process.

[0007] In some embodiments, the distal end of the conveyor is provided with a connection hole for connecting to an adjustment line on an operating handle.

[0008] In the above embodiment, by providing a connecting hole at the distal end of the delivery body, with the connecting hole spaced apart from the slide rail, and one end of the adjustment line on the operating handle connected to the connecting hole, the distal end of the delivery body can be bent and unfolded when the operating handle drives the adjustment line to move, making it easier to fix the distal end of the delivery body around the organ.

[0009] In some embodiments, each of the delivery bodies includes a connecting segment, a transition segment, and a support segment, one end of the connecting segment being connected to the connecting end and the other end being connected to one end of the transition segment, and the other end of the transition segment being connected to the support segment; wherein the transition segments of each delivery body are adapted to be spaced apart from each other and extended, and the end of the support segment is used to support an organ tissue.

[0010] In the above embodiments, the delivery body includes a connecting section, a transition section, and a support section. One end of the connecting section is connected to the connecting end, and the transition section is located between the connecting section and the support section. When the transition section and the support section reach the predetermined position of the organ tissue, the curvature of the transition section and the support section can be adjusted by the adjustment line on the operating handle. That is, the adjustment line can move multiple transition sections away from each other and unfold them, and can bend and deform the end of the support section to facilitate support on the organ and prevent damage to the organ.

[0011] In some embodiments, when the transition section is in an unfolded state, the angle between the transition section and the direction perpendicular to the connecting section is in the range of 8° to 12°; and / or, when the support section is in a state of being supported on the organ, the angle between the support section and the extension direction of the connecting section is in the range of 6° to 10°.

[0012] In the above embodiments, when implanting medical devices such as organ repair components during mitral and tricuspid valve repair surgery, the angle between the straight line of the transition segment and the direction perpendicular to the connecting segment is set between 8° and 12°, and the angle between the straight line of the support segment and the extension direction of the connecting segment is set between 6° and 10°. This allows for the adaptation to the size of the mitral or tricuspid valve, ensuring that the support segment can support the organ and improving the safety of organ repair component delivery.

[0013] In some embodiments, when the plurality of transition segments are unfolded, the connecting line at the distal end is a partial circle; wherein the diameter of the partial circle is in the range of 30mm to 55mm, and the partial circle occupies 2 / 3 to 3 / 4 of the area of ​​the circle.

[0014] In the above embodiments, when implanting organ repair components during mitral and tricuspid valve repair surgery, the distal connections of multiple delivery bodies form a partial circle when deployed. The area of ​​this partial circle, formed by the lines connecting the distal ends of the multiple delivery bodies, occupies 3 / 4 to 2 / 3 of the total circle area, corresponding to the outer contour of the mitral or tricuspid valve. The end of the support segment is used to support the local periphery of the heart, preventing damage to organ tissues. Since the heart size varies among individuals and age groups, setting the diameter of the partial circle formed by the lines connecting the distal ends of the delivery bodies within the range of 30mm to 55mm allows for compatibility with the outer contour dimensions of the hearts of different populations, thus improving the product's applicability.

[0015] In some embodiments, the connecting end has an installation port, which is connected to the slide rail.

[0016] In the above embodiments, by opening an installation port for installing the conveying carrier at the connection end and connecting the installation port to the slide rail, the conveying carrier can be slidably connected to the slide rail through the installation port. The structure and principle are relatively simple and easy to implement.

[0017] For example, the connection end is tubular.

[0018] In some embodiments, the mounting port includes a first notch and a second notch communicating with the first notch, wherein the second notch extends circumferentially along the connection end and communicates with each of the slides.

[0019] In the above embodiment, the mounting port includes a first notch and a second notch. The first notch is located above the slide groove and is used to mount the transport carrier. The second notch is connected to the first notch and extends circumferentially along the connecting end and is connected to each slide. When the transport carrier is loaded into the transport channel formed between multiple transport bodies through the first notch, the sliding connection part of the transport carrier is slidably connected to the slide through the second notch. Specifically, the second notch extends circumferentially along the connecting end, so that the mounting carrier can move along the extension direction of the second notch during installation. This allows the sliding connection part of the transport carrier to selectively slide with the slides of multiple transport bodies, facilitating the transport of multiple organ repair components.

[0020] In some embodiments, a transition groove is provided between the slide and the second notch, and the width of the transition groove gradually decreases from one end connected to the second notch to the other end.

[0021] In the above embodiments, by providing a transition groove between the slide and the second notch, and setting the width of the transition groove to gradually decrease from one end connected to the second notch to the other end, the sliding connection of the conveying carrier can be slidably connected to the slide, thereby effectively improving the installation efficiency of the conveying carrier.

[0022] In some embodiments, the device further includes a transport carrier for loading the organ repair component and adapted to move along the slide.

[0023] In the above embodiments, there can be multiple transport carriers, which can carry different medical devices and can move along the slides on the transport body to achieve the transport of multiple medical devices.

[0024] In some embodiments, the slide is a groove extending along the extension direction of the conveyor body; the conveying carrier includes a carrier portion, a sliding connecting portion connected to the carrier portion, and a limiting portion connected to the sliding connecting portion, the sliding connecting portion passing through the groove, and the carrier portion and the limiting portion being located on both sides of the groove respectively.

[0025] In the above embodiments, each conveyor body is provided with a chute, and each chute extends along the extension direction of the conveyor body. The conveying carrier includes a carrier part, a sliding connecting part, and a limiting part. The carrier part is located inside the chute and is used to load the medical device; the sliding connecting part is adapted to the chute, and the conveying carrier is slidably connected to the chute through the sliding connecting part; the limiting part is located outside the chute and is connected to the sliding connecting part, thereby enabling the conveying carrier to move along the conveying path to a preset position on the organ, thus realizing the delivery of the medical device and ensuring that it does not detach from the sliding path during delivery.

[0026] In some embodiments, the plurality of conveyors surround a conveying channel; the carrier portion and the limiting portion are located inside and outside the conveying channel, respectively.

[0027] In the above embodiments, specifically, the transport carrier can move along the transport channel. When the transport carrier transports the medical device, the carrier part and the limiting part of the transport carrier are located inside and outside the transport channel enclosed by multiple transport bodies, respectively.

[0028] In some embodiments, the apparatus includes a gathering member for gathering a plurality of transport bodies.

[0029] In the above embodiments, since the conveyor body is prone to deformation during the conveying process, by setting a gathering member that is connected to multiple conveyor bodies and used to gather multiple conveyor bodies, the gathering member can play the role of fixing and binding multiple conveyor bodies, preventing them from deforming or knotting during the conveying process.

[0030] In some embodiments, the gathering member is a gathering sleeve sleeved on the outside of the plurality of conveyors; or, the gathering member includes a gathering tube and a plurality of gathering pieces spaced apart on the outer periphery of the gathering tube, the number of gathering pieces being the same as the number of conveyors; the gathering tube is located between the plurality of conveyors, and the gathering tube and each gathering piece are respectively located on both sides of the slide corresponding to the gathering piece.

[0031] In the above embodiments, the gathering element can be a gathering sleeve fitted around the outer periphery of multiple conveying bodies. The gathering sleeve can tighten and limit the movement, preventing the multiple conveying bodies from deforming or knotting during the conveying process. The gathering element can also be a gathering tube and multiple gathering plates spaced apart on the outer periphery of the gathering tube. In this case, when conveying the conveying body inside the sheath, the gathering tube is placed between the multiple conveying bodies, and the gathering tube and each gathering plate are correspondingly placed on both sides of the slide corresponding to that gathering plate. The multiple gathering plates can limit the movement, preventing the multiple conveying bodies from deforming or knotting during the conveying process.

[0032] In some embodiments, the connecting end is integrally formed with the plurality of conveying bodies; and / or, the conveying body includes a flexible sheet; and / or, the conveying component includes a nickel-titanium shape memory alloy component.

[0033] In the above embodiments, the connecting end of the conveyor is integrally formed with multiple conveyor bodies, eliminating the need for assembly and helping to improve product production efficiency.

[0034] The conveyor body includes a flexible sheet, which has a certain degree of flexibility, making it easy to adjust the far end of the conveyor body through devices such as operating lines, so that multiple conveyors are kept apart from each other.

[0035] The conveyor is made of nickel-titanium shape memory alloy, which has a shape memory effect and can restore its original shape after use, thus making it easy to reuse.

[0036] In a second aspect, embodiments of this application provide a system for an interventional implantable medical device, comprising: a sheath; an operating handle connected to the proximal end of the sheath, the operating handle being connected to an adjustment line; and a device as described in any one of the embodiments of the first aspect, the device being adapted to be retracted within the sheath, the operating handle being used to adjust the distal ends of a plurality of delivery bodies away from each other via the adjustment line, so that the distal ends of the plurality of delivery bodies bend and unfold and are supported on organ tissue.

[0037] The system for implanting organ repair components provided in the second aspect of this application includes the device described in any one of the first aspect embodiments, and therefore has the technical effects described in any of the above embodiments, which will not be repeated here.

Detailed Implementation

[0049] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0050] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] Please refer to Figures 1 to 3 In a first aspect, embodiments of this application provide an apparatus for an interventional implantable medical device, comprising: a delivery member 100, including a connecting end 11 and a plurality of delivery bodies 12 connected to the connecting end 11, the delivery bodies 12 being provided with a slide for delivering the medical device, and the distal ends of the plurality of delivery bodies 12 being adapted to be far apart from each other.

[0052] In the above embodiments, the delivery member 100 includes a connecting end 11 and a plurality of delivery bodies 12 connected to the connecting end 11. When the medical device is implanted, the connecting end 11 is located on the side away from the organ relative to the delivery body 12. The plurality of delivery bodies 12 are spaced apart, and each delivery body 12 is provided with a slide for delivering the medical device, so that the medical device is delivered to a preset position in the organ tissue by the carrier along the slide, thereby completing the implantation of the medical device. The device for interventional implantation of medical devices provided in this application, after positioning the distal end of the delivery body with the organ tissue, delivers multiple medical devices through the slides on the multiple delivery bodies, without the need for repeated installation and positioning, which improves the efficiency of medical device delivery, reduces the possibility of organ damage during medical device delivery, and effectively improves the safety and reliability of medical devices during implantation.

[0053] Please refer to Figure 2 and Figure 3 In some embodiments, the distal end of the conveyor 12 is provided with a connection hole 125 for connecting to the adjustment line on the operating handle.

[0054] In the above embodiment, a connecting hole 125 is provided at the distal end of the delivery body 12. The connecting hole 125 is spaced apart from the slide. One end of the adjustment line on the operating handle is connected to the connecting hole 125. When the operating handle drives the adjustment line to move, it can drive the distal end of the delivery body 12 to bend and unfold, which makes it easy to fix the distal end of the delivery body 12 around the organ.

[0055] Please refer to Figure 2 In some embodiments, each delivery body 12 includes a connecting section 121, a transition section 122, and a support section 123. One end of the connecting section 121 is connected to the connecting end 11, and the other end is connected to one end of the transition section 122. The other end of the transition section 122 is connected to the support section 123. The transition sections 122 of each delivery body 12 are adapted to be spaced apart from each other and extended. The end of the support section 123 is used to support the organ tissue.

[0056] In the above embodiment, the delivery body 12 includes a connecting section 121, a transition section 122, and a support section 123. One end of the connecting section 121 is connected to the connecting end 11. The transition section 122 is located between the connecting section 121 and the support section 123. When the transition section 122 and the support section 123 reach the predetermined position of the organ tissue, the curvature of the transition section 122 and the support section 123 can be adjusted by the adjustment line on the operating handle. That is, the adjustment line can move multiple transition sections 122 away from each other and spread them out, and can bend and deform the end of the support section 123 so as to support it on the organ and prevent damage to the organ.

[0057] Please refer to Figure 3 In some embodiments, the transition section 122 is in an unfolded state, and the angle between the transition section 122 and the direction perpendicular to the connecting section 121 is in the range of 8° to 12°.

[0058] Please refer to Figure 3 In some embodiments, the support segment 123 is in a state of being supported on the organ, and the angle between the support segment 123 and the connecting segment 121 along the extension direction is in the range of 6° to 10°.

[0059] In the above embodiments, when implanting medical devices such as organ repair components during mitral and tricuspid valve repair surgery, the angle between the straight line of the transition segment 122 and the direction perpendicular to the connecting segment 121 is set between 8° and 12°, and the angle between the straight line of the support segment 123 and the extension direction of the connecting segment 121 is set between 6° and 10°. This allows for the adaptation to the size of the mitral or tricuspid valve, ensuring that the support segment 123 can support the organ and improving the safety of the organ repair component during delivery.

[0060] Please refer to Figure 4 In some embodiments, the line connecting the distal ends of the plurality of transition segments 122 when unfolded is a partial circle; wherein the diameter of the partial circle is in the range of 30mm to 55mm, and the partial circle occupies 2 / 3 to 3 / 4 of the area of ​​the circle.

[0061] In the above embodiments, when organ repair components are implanted during mitral or tricuspid valve repair surgery, the line connecting the distal ends of the multiple delivery bodies 12 when they are deployed is partially circular, and this partially circular part occupies 3 / 4 to 2 / 3 of the area of ​​the circle, so as to correspond to the outer contour of the mitral or tricuspid valve of the heart. The end of the support segment 123 is used to support the local periphery of the heart to prevent damage to organ tissues.

[0062] Since the heart size varies from person to person or age group, the diameter of the partial circle formed by the connecting lines at the distal ends of the multiple delivery bodies 12 when they are unfolded is set in the range of 30mm to 55mm. This allows the product to be adapted to the outer contour size of the heart of different people, which helps to improve the applicability of the product.

[0063] In some embodiments, the connecting end 11 has an installation port that is connected to the slide rail.

[0064] In the above embodiments, by opening an installation port for installing the conveying carrier 101 at the connecting end 11 and connecting the installation port to the slide, the conveying carrier 101 can be slidably connected to the slide through the installation port. The structure and principle are relatively simple and easy to implement.

[0065] For example, the connecting end 11 is tubular.

[0066] Please refer to Figures 1 to 3 In some embodiments, the mounting port includes a first notch 111 and a second notch 112 communicating with the first notch 111, and the second notch 112 extends circumferentially along the connecting end 11 and communicates with each slide.

[0067] In the above embodiment, the mounting port includes a first notch 111 and a second notch 112. The first notch 111 is located above the slide groove 124 and is used to mount the transport carrier 101. The second notch 112 is connected to the first notch 111 and extends circumferentially along the connecting end 11 and is connected to each slide. When the transport carrier 101 is loaded into the transport channel 13 formed between multiple transport bodies 12 through the first notch 111, the sliding connection part 1012 of the transport carrier 101 is slidably connected to the slide through the second notch 112. Specifically, the second notch 112 is arranged to extend circumferentially along the connecting end 11, so that the mounting carrier can move along the extension direction of the second notch 112 during installation, thereby enabling the sliding connection part 1012 of the transport carrier 101 to selectively slide with the slides of multiple transport bodies 12, which facilitates the transport of multiple organ repair components.

[0068] Please refer to Figure 2 In some embodiments, a transition groove 126 is provided between the slide and the second notch 112, and the width of the transition groove 126 gradually decreases from one end connected to the second notch 112 to the other end.

[0069] In the above embodiment, by providing a transition groove 126 between the slide and the second notch 112, and setting the width of the transition groove 126 to gradually decrease from one end connected to the second notch 112 to the other end, the sliding connection portion 1012 of the conveying carrier 101 is slidably connected to the slide groove 124, thereby effectively improving the installation efficiency of the conveying carrier 101.

[0070] Please refer to Figure 6 In some embodiments, a transport carrier 101 is also included, which is used to load organ repair components and is adapted to move along a slide.

[0071] In the above embodiments, there can be multiple transport carriers 101. Multiple transport carriers 101 can be loaded with different medical devices and can move along the slide on the transport body 12 to realize the transport of multiple medical devices.

[0072] Please refer to Figure 5 In some embodiments, the slide is a groove 124 extending along the extension direction of the conveyor 12; the conveyor 101 includes a carrier portion 1011, a sliding connection portion 1012 connected to the carrier portion 1011, and a limiting portion 1012 connected to the sliding connection portion 1012. The sliding connection portion 1012 passes through the groove 124, and the carrier portion 1011 and the limiting portion 1012 are located on both sides of the groove 124.

[0073] In the above embodiments, each conveyor 12 is provided with a groove 124, and each groove 124 extends along the extension direction of the conveyor 12. The conveying carrier 101 includes a carrier part 1011, a sliding connection part 1012, and a limiting part 1012. The carrier part 1011 is located inside the groove 124 and is used to load medical devices. The sliding connection part 1012 is adapted to the groove 124, and the conveying carrier 101 is slidably connected to the groove 124 through the sliding connection part 1012. The limiting part 1012 is located outside the groove 124 and is connected to the sliding connection part 1012, so that the conveying carrier 101 can move along the conveying path to a preset position of the organ to realize the delivery of medical devices and ensure that it will not detach from the sliding path during the delivery process.

[0074] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, a plurality of conveying bodies 12 surround a conveying channel 13; the carrier portion 1011 and the limiting portion 1012 are located inside and outside the conveying channel 13, respectively.

[0075] In the above embodiments, specifically, the transport carrier 101 can move along the transport channel 13. When the transport carrier 101 transports the medical device, the carrier part 1011 and the limiting part 1012 of the transport carrier 101 are located inside and outside the transport channel 13 enclosed by multiple transport bodies 12, respectively.

[0076] Please refer to Figure 7 In some embodiments, the apparatus includes a gathering member 102 for gathering a plurality of transport bodies 12.

[0077] In the above embodiment, since the conveyor body 12 is prone to deformation during the conveying process, by setting a gathering member 102 connected to multiple conveyor bodies 12 and used to gather multiple conveyor bodies 12, the gathering member 102 can play the role of fixing and binding multiple conveyor bodies 12, preventing them from deforming or knotting during the conveying process.

[0078] Please refer to Figure 9 In some embodiments, the gathering member 102 is a gathering sleeve 103 sleeved on the outside of the plurality of conveyors 12.

[0079] In the above embodiments, the gathering member 102 may be a gathering sleeve 103 sleeved on the outer periphery of the multiple conveying bodies 12. The gathering sleeve 103 can play a tightening and limiting role to prevent the multiple conveying bodies 12 from deforming or knotting during the conveying process.

[0080] Please refer to Figure 8 In some embodiments, the gathering member 102 includes a gathering tube 1021 and a plurality of gathering pieces 1022 spaced apart on the outer periphery of the gathering tube 1021. The number of gathering pieces 1022 is the same as the number of conveyors 12. The gathering tube 1021 is located between the plurality of conveyors 12, and the gathering tube 1021 and each gathering piece 1022 are located on both sides of the slide corresponding to the gathering piece.

[0081] In the above embodiments, the gathering member 102 may also be a gathering tube 1021 and a plurality of gathering pieces 1022 spaced apart on the outer periphery of the gathering tube 1021. When conveying the conveying member 100 in the sheath, the gathering tube 1021 is placed between the plurality of conveying bodies 12, and the gathering tube 1021 and each gathering piece 1022 are correspondingly placed on both sides of the slide corresponding to the gathering piece. The plurality of gathering pieces 1022 can play a limiting role to prevent the plurality of conveying bodies 12 from deforming or knotting during the conveying process.

[0082] In some embodiments, the connecting end 11 and the plurality of conveying bodies 12 are integrally formed.

[0083] In some embodiments, the transport body 12 includes a flexible sheet.

[0084] In some embodiments, the conveyor 100 includes a nickel-titanium shape memory alloy component.

[0085] In the above embodiments, the connecting end 11 of the conveyor 100 is integrally formed with multiple conveyor bodies 12, eliminating the need for assembly and helping to improve product production efficiency.

[0086] The conveyor body 12 includes a flexible sheet, which has a certain degree of flexibility, making it easy to adjust the far end of the conveyor body 12 through devices such as operating lines, so that multiple conveyor bodies 12 are separated from each other.

[0087] The conveyor 100 is a nickel-titanium shape memory alloy component. Therefore, the nickel-titanium shape memory alloy component has a shape memory effect and can restore its original shape after use, thus making it easy to reuse.

[0088] In a second aspect, embodiments of this application provide a system for an interventional implantable medical device, comprising: a sheath; an operating handle connected to the proximal end of the sheath, and the operating handle being connected to an adjustment line; and a device as described in any of the embodiments of the first aspect, the device being adapted to be retracted within the sheath, the operating handle being used to drive the device to be transported along the sheath, and to adjust the curvature of the distal ends of a plurality of delivery bodies 12 via the adjustment line, so that the distal ends of the plurality of delivery bodies 12 unfold and are supported on organ tissue.
