Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a delivery system for an artificial mitral valve implant. Background Technology

[0002] An artificial mitral valve implant is an artificial device used to replace a damaged or dysfunctional mitral valve. The mitral valve is located between the left atrium and left ventricle of the heart, and its core function is to ensure unidirectional blood flow during the heart's pumping cycle: it opens during ventricular diastole, allowing oxygenated blood to flow from the left atrium into the left ventricle; and it closes rapidly during ventricular systole, effectively preventing blood from flowing back into the left atrium. When the mitral valve becomes insufficient (regurgitation) or narrowed due to degenerative changes, rheumatic diseases, or other reasons, it severely disrupts hemodynamics, leading to excessive cardiac volume or pressure load. In the long term, this can cause left ventricular enlargement and heart failure. In cases of serious consequences, artificial mitral valve implants precisely replace diseased valves, restoring their normal "one-way valve" function and thus rebuilding the heart's normal blood flow regulation mechanism. Based on materials and design, they are mainly divided into mechanical valves and bioprosthetic valves. Mechanical valves are made of high-strength synthetic materials (such as pyrolytic carbon) and have good durability, but patients need to take anticoagulants for life to prevent thrombosis. Bioprosthetic valves use processed animal tissue (such as porcine valves or bovine pericardium) or allogeneic valves, and their hemodynamics are closer to those of natural valves. They usually do not require lifelong anticoagulation, but there is a risk of calcification or degeneration over time, and their durability is relatively short.

[0003] To implant an artificial mitral valve into the target location, a surgical approach is necessary. The traditional method is open-heart surgery, where the heart is directly exposed for valve replacement under cardiopulmonary bypass. In recent years, minimally invasive techniques such as transcatheter mitral valve replacement (TMVR) have developed rapidly. These techniques allow the compressed valve device to be delivered to the location of the native mitral valve via a catheter through the femoral vein or apex and then released. Regardless of the method used, precise delivery, accurate positioning, and secure fixation are crucial. This not only ensures the normal function of the implanted valve but also minimizes damage to surrounding tissues (such as ventricular structures and the conduction system), reducing the risk of complications such as paravalvular leakage and conduction block. These are key to surgical success and a good long-term prognosis for the patient.

[0004] However, in existing technologies, stents mostly employ mechanical locking or traction release mechanisms. These methods often make it difficult to achieve the step-by-step, orderly deployment of the upper and lower stents, which can easily lead to stent displacement, tilting, or twisting during implantation, affecting precise anchoring and increasing the risk of complications such as paravalvular leakage and conduction block. At the same time, existing artificial heart valve devices mostly adopt an integrated design of valve and stent. Once the bioprosthetic valve undergoes structural degeneration or functional failure, the entire stent system needs to be replaced through open-heart surgery or complex interventional procedures. This not only significantly increases the surgical risks and trauma for patients but also increases medical costs. Furthermore, existing systems generally do not have the function of independent replacement of bioprosthetic valves, which limits the maintenance and repair capabilities after long-term implantation and makes it difficult to meet patients' clinical needs for long-lasting, maintainable implantable devices.

[0005] Therefore, the present invention provides a delivery system for an artificial mitral valve implant. Summary of the Invention

[0012] As a preferred technical solution of this application, the third receiving cavity is provided with an implant component, and the magnetism of the upper and lower sides of the first electromagnetic block can be independently controlled.

[0013] As a preferred technical solution of this application, the implant component includes a vertical support rod, the outer surface of which is disposed inside the third receiving cavity, a folded mesh is fixedly connected to the middle of the outer surface of the vertical support rod, a second sewing cloth is fixedly connected to the inside of the vertical support rod, and a bio-valve is fixedly connected to the inside of the second sewing cloth.

[0014] As a preferred technical solution of this application, the suction assembly includes an integrated box, the upper surface of which is fixedly connected to the bottom end of the delivery tube, a sealing plug is inserted into the bottom end of the integrated box, and an extraction tube is fixedly connected to one side of the outer surface of the integrated box.

[0015] As a preferred technical solution of this application, a fastening tube is fixedly connected to the other side of the outer surface of the integrated box, and the inside of the fastening tube is fixedly connected to one end of the outer surface of the extension tube.

[0016] As a preferred technical solution of this application, the upper and lower ends of the vertical support rod are outwardly flared and adapted to the shapes of the lower and upper supports.

[0017] The beneficial effects of this invention are as follows: 1. The artificial mitral valve implant delivery system of the present invention, through the setting of a first protective component, attracts a second electromagnetic block under the action of a first electromagnetic block, which can drive the second receiving cavity away from the first receiving cavity, thereby realizing the unlocking and release of the stent. The operation is simple and quick, the release process is highly controllable, and the release sequence is to first release the upper stent, and after it is fully unfolded and fixed, the first receiving cavity is moved down to release the lower stent.

[0018] 2. The artificial mitral valve implant delivery system of the present invention, through the inflatable component, can apply radial support force to the upper and lower stents when the airbag inflates, pushing the stents to fully expand synchronously at both ends, ensuring that the stent body achieves complete and uniform expansion at the target position, which helps the stent to fit tightly against the tissue wall of the implantation site, improves fixation stability, and effectively improves the accuracy and safety of implantation.

[0019] 3. The artificial mitral valve implant delivery system of the present invention, through the setting of a second protective component, can attract a third electromagnetic block under the action of a first electromagnetic block, thereby driving a fourth receiving cavity away from the third receiving cavity, realizing the release of the bottom end of the vertical support rod. After the folded mesh unfolds under the action of hemodynamics and its position is corrected to be stably located in the middle of the inner wall of the lower stent and the upper stent, the third receiving cavity is controlled to move upward, which can release the top end of the vertical support rod, and finally complete the precise unfolding and fixation of the bioprosthetic valve, thereby realizing the independent implantation and release of the bioprosthetic valve without replacing the entire external stent system, simplifying the operation process, reducing the frequency of repeated surgery due to valve failure, extending the overall service life of the stent system, and improving the flexibility and safety of treatment.

[0020] 4. The artificial mitral valve implant delivery system of the present invention, through the set suction component and delivery tube, after the bottom end of the integrated box and the guide wire are sealed by the sealing plug, the vacuum negative pressure device connected to the suction tube can promptly suction and remove blood clots, tissue debris or other obstructions, as well as excess blood fluid that may accumulate at the front end of the delivery tube during the delivery process, effectively maintaining the cleanliness and unobstructedness of the delivery channel, significantly ensuring the smoothness and stability of the artificial valve delivery process, and reducing the operational risks caused by obstruction or unclear vision.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Reference Figure 1 - Figure 9 This invention provides three technical solutions: Example 1: A delivery system for an artificial mitral valve implant includes a guide wire 1, a delivery tube 2 slidably connected to the outer surface of the guide wire 1, a suction component fixedly connected to the bottom end of the delivery tube 2, a first protective component fixedly connected to the bottom end of the outer surface of the delivery tube 2, a second protective component fixedly connected to the top end of the outer surface of the delivery tube 2, and a first electromagnetic block 3 fixedly connected to the middle part of the outer surface of the delivery tube 2. The first protective component includes a first receiving cavity 4. The bottom end of the inner wall of the first receiving cavity 4 is fixedly connected to the bottom end of the outer surface of the conveying pipe 2. A first annular electromagnet 5 is fixedly connected to the upper surface of the first receiving cavity 4. A second annular electromagnet 6 is attracted to the upper surface of the first annular electromagnet 5. A second receiving cavity 7 is fixedly connected to the upper surface of the second annular electromagnet 6. A second electromagnetic block 8, which is attracted to the lower surface of the first electromagnetic block 3, is fixedly connected to the upper surface of the second receiving cavity 7. Through an external control system, the first annular electromagnet 5 and the second annular electromagnet 6 are remotely de-energized, causing them to... Once the magnetic attraction is lost, the first electromagnetic block 3 generates a magnetic attraction force to attract the second electromagnetic block 8, which can drive the second storage cavity 7 away from the first storage cavity 4, thereby unlocking and releasing the stent. The operation is simple and quick, and the release process is highly controllable. The release sequence is as follows: first release the upper stent 11, and after it is fully unfolded and fixed, the lower delivery tube 2 drives the first storage cavity 4 to move down to release the lower stent 10. This ensures that the stent system maintains stable orientation during implantation, effectively avoids displacement or twisting, facilitates precise stent positioning, and improves surgical safety and success rate. The first receiving cavity 4 is provided with a first suture fabric 9, and the frame assembly is fixedly connected inside the first suture fabric 9. The first suture fabric 9 is a polymer fabric coated with bioactive factors. The first suture fabric 9 is sewn to the frame assembly with polyethylene sutures. The first suture fabric 9 can not only effectively improve the biocompatibility of the frame, reduce the host's immune rejection response to the implant, and significantly reduce the risk of local inflammatory response and restenosis of vascular or valve perivalve tissues, but also enhance the overall structural integrity and support stability of the stent. Moreover, its flexible and dense fabric properties help promote the adhesion and growth of endothelial cells.

[0026] The frame assembly includes a lower support 10, with the inner surface of the first sewn fabric 9 fixedly connected to the outer surface of the lower support 10. An upper support 11 is fixedly connected to the upper surface of the lower support 10. Chamfers 12 are fixedly connected to both sides of the lower support 10 and the upper support 11. The arrangement of the lower support 10 and the upper support 11 can provide limiting support at both ends of the device, thereby significantly improving the stability and fixation of the entire frame at the target position, ensuring the firm installation of the device at the mitral valve, and reducing the risk of displacement. In addition, the design of the chamfers 12 further enhances the limiting effect, effectively preventing the frame from falling off or misaligning, and ensuring the long-term stable use of the device.

[0027] There are several lower stents 10 and several upper stents 11. The lower stents 10 and the upper stents 11 are equipped with inflatable components. The specific number of lower stents 10 and upper stents 11 is between 2 and 6. Several lower stents 10 and upper stents 11 are arranged in a ring by chamfering 12 in order to support the bioprosthetic valve 23.

[0028] The inflation assembly includes an airbag 13. The outer surface of the airbag 13 is disposed inside the lower support 10 and the upper support 11. An air distribution tube 14 is fixedly connected inside the airbag 13. An extension tube 15 is fixedly connected to one end of the air distribution tube 14. The bottom end of the inner wall of the airbag 13 is fixedly connected to the delivery tube 2, and the top end of the inner wall of the airbag 13 is slidably connected to the delivery tube 2. When the airbag 13 is not deployed, it is contracted inside the first receiving cavity 4 and the second receiving cavity 7. An external air supply device is connected through the extension tube 15 to deliver waterless and oil-free medical pure air to the inside of the airbag 13 through the air distribution tube 14, causing the airbag 13 to inflate. This applies radial support force to the upper support 11 and the lower support 10, pushing the two ends of the support to expand synchronously and fully, ensuring that the support body achieves complete and uniform expansion at the target position. This helps the support to fit tightly against the tissue wall of the implantation site, improves fixation stability, and effectively improves the accuracy and safety of implantation.

[0029] Example 2: Based on Embodiment 1: The second protective component includes a third receiving cavity 16. The top end of the inner wall of the third receiving cavity 16 is fixedly connected to the top end of the outer surface of the conveying pipe 2. A third annular electromagnet 17 is fixedly connected to the lower surface of the third receiving cavity 16. A fourth annular electromagnet 18 is attracted to the lower surface of the third annular electromagnet 17. A fourth receiving cavity 19 is fixedly connected to the lower surface of the fourth annular electromagnet 18. A third electromagnetic block 20, which is attracted to the upper surface of the first electromagnetic block 3, is fixedly connected to the lower surface of the fourth receiving cavity 19. When the third annular electromagnet 17 and the fourth annular electromagnet 18 are de-energized and lose their magnetic attraction, the first electromagnetic block 3 is then energized and generates a magnetic attraction force, which can attract the third electromagnetic block 20, thereby driving... The fourth receiving cavity 19 is moved away from the third receiving cavity 16, allowing the release of the bottom end of the vertical support rod 21. After the folded mesh 28 unfolds under deformation memory and hemodynamics, and its position is corrected to make it stable in the middle of the inner wall of the lower stent 10 and the upper stent 11, it is then moved upward through the upper delivery tube 2 to control the upward movement of the third receiving cavity 16, which can release the top end of the vertical support rod 21. Finally, the precise unfolding and fixation of the bioprosthetic valve 23 is completed, thereby achieving independent implantation and release of the bioprosthetic valve 23 without the need to replace the entire external stent system. This simplifies the operation process, reduces the frequency of repeated surgery due to valve failure, extends the overall service life of the stent system, and improves the flexibility and safety of treatment.

[0030] The third receiving cavity 16 contains an implant assembly. The magnetism of the upper and lower sides of the first electromagnetic block 3 can be independently controlled. By setting independent magnetic circuits on the upper and lower sides of the first electromagnetic block 3, independent control of the magnetism can be achieved. This design allows the first electromagnetic block 3 to precisely attract and release the second electromagnetic block 8 and the third electromagnetic block 20 in a preset order according to the surgical procedure. By controlling the magnetic field step by step, the lower stent 10 and the upper stent 11 can be deployed in sequence, as well as the subsequent release of the bioprosthetic valve 23, ensuring that the entire implantation process has good timing and controllability.

[0031] The implant component includes a vertical support rod 21. The outer surface of the vertical support rod 21 is disposed inside the third receiving cavity 16. A folded mesh 28 is fixedly connected to the middle of the outer surface of the vertical support rod 21. A second suture fabric 22 is fixedly connected inside the vertical support rod 21. A bioprosthetic valve 23 is fixedly connected inside the second suture fabric 22. The folded mesh 28 is mesh-shaped and made of nickel-titanium alloy. During release, the folded mesh 28 can drive the vertical support rod 21 to expand radially in all directions, thereby pushing the second suture fabric 22 to fully unfold. The second suture fabric 22 is also a polymer fabric coated with bioactive factors. The second suture fabric 22 is made of polyethylene. The bioprosthetic valve 23 is sutured with a suture-like suture and a folded mesh 28. The second suture 22 not only provides a stable mounting base for the bioprosthetic valve 23, ensuring its precise positioning and firm fixation, but also plays a protective role during delivery. Its flexible structure can effectively buffer external forces and prevent the bioprosthetic valve 23 from being damaged by mechanical friction or compression when passing through tortuous anatomical paths such as the vascular system. When the device reaches the target position, the orderly unfolding of the second suture 22 can also guide the bioprosthetic valve 23 to open smoothly and symmetrically, ensuring its functional integrity and hemodynamic performance, and significantly improving the safety and reliability of implantation.

[0032] The vertical strut 21 has outward-expanding ends that match the shapes of the lower support 10 and the upper support 11. The vertical strut 21, the folded mesh 28, the lower support 10, the upper support 11, and the chamfer 12 are all made of nickel-titanium alloy with shape memory. The outward-expanding structure design facilitates the installation and positioning of the bioprosthetic valve 23, while ensuring that it can fit tightly against the inner walls of the lower support 10 and the upper support 11 after release, improving the stability and sealing of the overall structure and effectively reducing the risk of complications such as paravalvular leakage. At the same time, each frame is made of titanium alloy with shape memory properties, which is easy to transport in a compressed state. When it reaches the target position and is released from restraint, the deformation recovery ability of the material can realize the automatic and orderly unfolding of each frame, which simplifies the implantation operation, improves the accuracy and reliability of release, and enhances the adaptability of the stent in complex anatomical environments.

[0033] Example 3: Based on Embodiments 1 and 2: The aspiration assembly includes an integrated box 24, the upper surface of which is fixedly connected to the bottom end of the delivery tube 2. A sealing plug 25 is inserted into the bottom end of the integrated box 24, and an extraction tube 26 is fixedly connected to one side of the outer surface of the integrated box 24. After the sealing plug 25 seals the bottom end of the integrated box 24 and the guide wire 1, a vacuum negative pressure device is connected to the extraction tube 26. During the delivery process, blood clots, tissue debris or other obstructions that may accumulate at the front end of the delivery tube 2, as well as excessive blood, can be promptly aspirated and removed. This effectively maintains the cleanliness and unobstructedness of the delivery channel, significantly ensuring the smoothness and stability of the artificial valve delivery process and reducing the operational risks caused by obstruction or unclear vision.

[0034] A fastening tube 27 is fixedly connected to the other side of the outer surface of the integrated box 24. The inside of the fastening tube 27 is fixedly connected to one end of the outer surface of the extension tube 15. The fastening tube 27 is fixedly connected to the extension tube 15 at a suitable position. The fastening tube 27 can fix the protruding part of the extension tube 15, which not only effectively prevents the extension tube 15 inside the delivery tube 2 from bending, shaking or retracting during operation, ensuring structural stability, but also ensures the stability of the position of the external extension tube 15, which facilitates the quick and reliable connection of the extension tube 15 to the external gas supply device, improves assembly efficiency and sealing, and ensures the continuity and safety of the gas delivery process.

[0035] Working principle: First, the sealing plug 25 seals the bottom of the integrated box 24 and the guide wire 1. Then, through the coordinated operation of navigation image guidance and vascular access planning, the delivery tube 2 is precisely delivered to the target position of the mitral valve along the guide wire 1. At the same time, a vacuum negative pressure device connected to the extraction tube 26 can continuously or as needed aspirate any blood clots, tissue debris, or other obstructions and excess blood fluid that may accumulate at the front end of the delivery tube 2 during the delivery process, promptly clearing potential obstacles. Next, the first annular electromagnet 5 and the second annular electromagnet 6 are... The power is cut off, causing it to lose its magnetic attraction. Then, the first electromagnetic block 3 is energized and generates a magnetic attraction force, which attracts the second electromagnetic block 8. This drives the second storage cavity 7 away from the first storage cavity 4, thus enabling the priority release of the upper support 11. After the upper support 11 has been fully deployed and initially fixed at the target position, the first storage cavity 4 is moved down simultaneously, releasing the lower support 10 and completing the anchoring of the lower end of the support. At the same time, the arrangement of the lower support 10 and the upper support 11 can provide limiting support for both the upper and lower ends of the device, and the design of the chamfer 12 can further enhance the... The strong limiting effect is achieved by firstly supplying a gas supply device via the extension tube 15, allowing waterless and oil-free medical pure air to be evenly delivered to the inside of the airbag 13 through the air distribution tube 14. This controls the expansion of the airbag 13, applying radial support force to the lower support 10 and the upper support 11, thus pushing the two ends of the support to expand radially synchronously and symmetrically. Finally, the third annular electromagnet 17 and the fourth annular electromagnet 18 are de-energized, releasing their magnetic constraints. Subsequently, under the action of the first electromagnetic block 3, the third electromagnetic block 20 is attracted, driving the fourth receiving cavity 19 to move away from the third electromagnetic block 20. After the third receiving cavity 16 is removed, the bottom end of the vertical support rod 21 is initially released. At this time, the folded net 28 gradually unfolds under the combined action of the recovery force of its own shape memory material and the blood flow force, and automatically corrects its position. After X-ray fluoroscopy confirms that it is stably located in the central area of ​​the inner wall of the lower support 10 and the upper support 11, the third receiving cavity 16 is then controlled to move upward, releasing the constraint on the top end of the vertical support rod 21 and completing the top end release. This process pushes the second suture cloth 22 to unfold evenly, thereby driving the bio-valve 23 to open symmetrically and smoothly.
