The slide drives the second support clamp to move relative to the base plate, thereby easily achieving relative movement of the adjustable bend structure and the outer sheath structure, while also achieving a stable fixation of the distal tube and the adjustable bend tube.

[0205] 3) The present invention can well clamp the delivery tube of the delivery handle of the transfemoral valve repair system by arranging a sliding support clamp at the proximal end, and the sliding support clamp can slide on the slide, thereby easily realizing the relative movement between the delivery handle and the adjustable bending structure and the outer sheath structure.

[0206] 4) The seat covers and elastic support members of the first support clamp and the second support clamp of the present invention are staggered and engaged, so they can be adapted to conveyors of different diameters, and have greater versatility.

[0207] 5) The first support clamp and the second support clamp are clamped at the distal tube of the outer sheath structure of the transfemoral valve repair system and the adjustable bend structure. The rubber material at this part is relatively soft and has moderate friction. During the operation, the transfemoral valve repair system can be rotated according to the needs of the operation to control the direction of the distal clamp of the transfemoral valve repair system, and the transfemoral valve repair system can be effectively prevented from rotating due to the existence of the rotation force after rotation. It can also avoid the transfemoral valve repair system from having relative movement with the first support clamp and the second support clamp during axial movement.

[0222] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0223] In the field of interventional medical devices, when describing the support frame for the transfemoral valve repair system of the present invention, "proximal end" and "proximal segment" refer to the side of the support frame for the transfemoral valve repair system of the present invention that is located in the direction of the end manipulated by the user, and accordingly, "distal end" and "distal segment" refer to the side of the support frame for the transfemoral valve repair system of the present invention that is away from the end manipulated by the user.

[0224] In the present invention, when one or more elements or components are described as being connected, joined, fixed, pivoted, hinged, coupled, attached, or otherwise interconnected, such interconnection may be direct between the components or may be indirect, such as through the use of one or more intervening components. Moreover, as used herein, references to "assembly," "component," "member," or "portion" should not be limited to a single structural component, member, or element, but may include an assembly of components, parts, or elements.

[0225] In the present invention, the terms "integrated", "integrally connected" and "integrally formed" refer to a structure formed in one step through a processing technology such as stamping, cutting, pouring, casting and the like, and the structure as a whole is an element and cannot be divided.

[0226] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0227] In the present invention, "axial" and "axis line" refer to the line between the distal end and the proximal end or the direction of these lines, as well as the parallel lines of the lines. Of course, sometimes it refers to the axial symmetry line of a certain axially symmetrical component or element itself. The specific understanding can be made appropriately based on the description and drawings.

[0228] like Figures 2A to 2DAs shown, the support frame for the transfemoral valve repair system of the present invention generally has a base plate 10, a guide frame 20 and a slide 30. The distal end of the base plate 10 can support the distal section of the transfemoral valve repair system. The guide frame 20 is fixed to the middle section and the proximal section of the base plate 10, and the guide frame 20 and the base plate 10 form an inclined angle with a lower distal end and a higher proximal end, for example, an angle between 10° and 30°. The slide 30 can be slidably arranged on the guide frame 20, and the slide 30 can support the middle section and the proximal section of the transfemoral valve repair system, and can drive the middle section and the proximal section of the transfemoral valve repair system to move relative to the distal section of the transfemoral valve repair system. The support frame for the transfemoral valve repair system of the present invention can also have a first support clamp 40a, a second support clamp 40b, a distal frame 60, an intermediate frame 70 and other structures. In one example, the support frame of the present invention can be provided with a sliding support clamp 50, such as Figure 2A In another example, the support frame of the present invention may also not have a sliding support clip 50, such as Figure 2B As shown, in another example of the present invention, the structures of the first support clamp 40a and the second support clamp 40b are similar to the sliding support clamp 50, except that there is no lower slidable work seat, such as Figure 2C shown.

[0229] like Figure 3A As shown, the base plate 10 is a flat, long, thin plate placed horizontally. It belongs to the base part of the entire support frame and is used to support other components. The distal end, middle part and proximal end of the base plate 10 respectively extend a small section toward both sides, so that the width of the distal end, middle part and proximal end of the base plate 10 is greater than the width of other parts, thereby forming a distal wide part, a middle wide part and a proximal wide part respectively. Such widening can make it more convenient to install other components. In this example, a first support clamp 40a is fixed to the distal wide part of the base plate 10, and the distal end and proximal end of the guide frame 20 are fixed to the middle wide part and the proximal wide part of the base plate 10 respectively. In another example, as Figure 3B As shown, the bottom plate 10 can be a flat, long thin plate placed horizontally, with the width from the far end to the near end always consistent, and can have two through holes on it to reduce material consumption and reduce costs.

[0230] like Figure 4As shown, the guide frame 20 is a long, inclined stent. The lower portion of the guide frame 20 has a short column 23 and a tall column 24. The short column 23 is located at the distal end of the guide frame 20, with its base fixed to the middle, wide portion of the base plate 10. The tall column 24 is located at the proximal end of the guide frame 20, with its base fixed to the proximal, wide portion of the base plate 10. The upper portion of the guide frame 20 has a guide groove 21 with an upward-facing opening. This is generally elongated and has a roughly U-shaped radial cross-section. The axial direction of the guide groove 21 aligns with the axial direction of the transfemoral valve repair system. The distal end of the lower surface of the guide groove 21 is fixedly connected to the top of the short column 23 and supported by the short column 23. The proximal end of the lower surface of the guide groove 21 is fixedly connected to the top of the tall column 24 and supported by the tall column 24. This secures the guide frame 20 to the middle and proximal sections of the base plate 10. The arrangement of the short posts 34 and tall posts 24 creates an angle between the guide slot 21 of the guide frame 20 and the horizontal, for example, between 10° and 30°. This tilted arrangement facilitates operation of the transfemoral valve repair system by medical personnel. Two parallel rails 22 are fixed to the inner sidewalls of the guide slot 21. A slider 32 at the bottom of the slide 30 slides between the two rails 22, with its eccentric wheel positioned within the guide slot 21.

[0231] like Figures 5A-5B As shown, in this example, the slide 30 can slide between the distal end and the proximal end on the guide frame 20, and the sliding direction of the slide 30 is the direction of the guide groove 21 inclined on the guide frame 20. The slide 30 has a flat plate 31 and a slider 32, and the slider 32 is fixed to the lower surface of the flat plate 31. The flat plate 31 can be a long flat thin plate, and the distal end can be slightly narrower, called the narrow section; the proximal end can be slightly wider, called the wide section. In one example, a long sliding hole 311 is set in the middle of the wide section of the flat plate 31 along the length direction, that is, in the axial direction, as shown in FIG. Figure 2A As shown, the axial direction of the sliding hole 311 is consistent with the axial direction of the transfemoral valve repair system. The lower part of the support clip 50 can slide in the sliding hole 311. In another example, the middle part of the wide section of the flat plate 31 may also not have a sliding hole, such as Figure 2B As shown, the delivery handle 220 of the transfemoral valve repair system can be placed directly on the wide section of the plate 31. In another preferred embodiment, baffles 312 are provided on both sides of the upper surface of the proximal section of the slide 30, such as the wide section, to prevent the delivery structure 200 of the transfemoral valve repair system from sliding off the slide 30.

[0232] like Figure 5BAs shown, in this example, the slider 32 is fixed to the lower surface of the flat plate 31. The flat plate 31 is located above the guide slot 21 of the guide frame 20, and the slider 32 is therefore located within the guide slot 21. The slider 32 comprises a slider body 321, two pairs of eccentrics 322, and a locking member 323. The slider body 321 is a rectangular block structure with a locking cavity 3211 in the middle. The slider 32 is fixed to the lower surface of the flat plate 31 by the slider body 321. The two pairs of eccentrics 322 are connected to the lower surface of the slider body 321. The two pairs of eccentrics 322 are located within the guide slot 21 and respectively abut against the two slide rails 22, allowing them to slide between the two slide rails 22. Figures 5C-5D As shown, the eccentric wheel 322 has a fixed end 3221, a resting end 3222 and a wheel axle 3223. The fixed end 3221 is embedded in the slider body 321; one end of the wheel axle 3223 is passed through a non-center portion of the fixed end 3221, and the other end is passed through the center portion of the resting end 3222. Since the wheel axle 3223 is passed through a non-center portion of the fixed end 3221, eccentric rotation can be achieved. The side surface of the resting end 3222 is a concave arc surface, while the slide rail 22 is a circular track with a convex arc surface on the outer surface. Therefore, the concave arc surface of the resting end 3222 can be rested on the slide rail 22 with a convex arc surface to achieve a better fit and prevent the eccentric wheel 322 from slipping when sliding on the slide rail 22. The locking member 323 is radially inserted through the slider body 321. By adjusting the locking member 323, the inner end of the locking member 323 can be pressed against the slide rail 22 for locking. Specifically, the locking member 323 comprises a locking inner block 3231 and a threaded knob 3232. The locking inner block 3231 is located within the locking cavity 3211. The threaded knob 3232 is radially threaded onto the sidewall of the slider body 321. The inner end of the threaded knob 3232 is fixedly connected to the locking inner block 3231. By rotating the threaded knob 3232, the locking inner block 3231 is adjusted to tightly abut against the slide rail 22, achieving locking. Once locked, the entire slider 30 cannot slide relative to the guide frame 20. When unlocked, relative sliding is possible again.

[0233] like Figures 6A to 6C As shown, the first support clip 40a and the second support clip 40b are fixed at the distal ends of the base plate 10 and the slide 30, respectively. The first support clip 40a and the second support clip 40b are used to support the outer sheath structure and the adjustable bending structure of the transfemoral valve repair system, respectively. The first support clip 40a and the second support clip 40b each have a base 41, a seat cover 42, an elastic support member 43, a pressure member 44, and a hinge 45.

[0234] In this example, the bases 41 of the first support clamp 40a and the second support clamp 40b are fixed to the distal wide portion of the base plate 10 and the distal end of the narrow section of the slide plate 30, respectively. The base 41 is roughly square in shape and has a hollow inner cavity 411, so the base 41 can be regarded as a box-shaped body, and the hollow inner cavity 411 can accommodate the elastic support member 43. The base 41 of the first support clamp 40a has a lower seat 412 and an upper seat 413, and is fixed to the distal wide portion of the base plate 10 by the bottom of the lower seat 412 of the first support clamp 40a. The upper seat 413 is integrally connected to the lower seat 412, and the lower seat 412 and the upper seat 413 form an angle, which is approximately 150 to 170 degrees. This angle allows the upper seat 413 to form a certain angle in the longitudinal direction, which is more convenient for the tilting posture of the transfemoral valve repair system during operation. The bottom of the second support clamp 40b is directly fixed to the bottom of the far end of the skateboard 30. Due to the arrangement of the short column 23 and the high column 24 of the guide frame 20, the skateboard 30 located on the guide frame 20 is still in an inclined posture. Therefore, although the base of the second support clamp 40b also has a lower section seat 412 and an upper section seat 413 integrally connected to the lower section seat 412, the lower section seat 412 and the upper section seat 413 of the second support clamp 40b only need to be in the same straight line plane, that is, the angle between them is 180 degrees. The base 41 has a first side wall and a second side wall that are arranged opposite to each other. The second side wall of the base 41 is provided with a snap 414, which can be snapped with the fastener of the seat cover 42. One of the side chain arms of the hinge 45 is connected to the upper surface of the base 41 and is close to the first side wall. The base 41 has a third side wall and a fourth side wall that are relatively arranged and adjacent to the first side wall and the second side wall of the base 41. The third side wall and the fourth side wall of the base 41 respectively have seat openings 415 for the transfemoral valve repair system to pass through at corresponding positions in the middle of the elastic support member 43.

[0235] In this example, a cover 42 snaps onto the base 41, and a pressure piece 44 is provided on the inner surface of the cover 42. The cover 42 is roughly square and, like the base 41, has a first sidewall and a second sidewall disposed opposite each other. The first sidewall of the cover 42 is on the same side as the first sidewall of the base 41, and the second sidewall of the cover 42 is also on the same side as the second sidewall of the base 41. The other arm of the hinge 45 is connected to the lower surface of the cover 42, near the first sidewall. Thus, the lower edge of the first sidewall of the cover 42 is pivotally connected to the upper edge of the first sidewall of the base 41 by the hinge 45. In other words, the cover 42 can be opened and closed on the base 41 using the hinge 45 as a pivot. The second sidewall of the cover 42 is snap-fitted to the second sidewall of the base 41. In one example, a fastener is provided on the second sidewall of the cover 42, and a snap-fit 414 is provided on the second sidewall of the base 41. The fastener of the cover 42 snaps into contact with the snap-fit 414 of the base 41. The fastener comprises a U-shaped buckle 421 and a buckle spring 422. One end of the U-shaped buckle 421 is movably mounted on the second side wall of the base 42, and the other end can be engaged in a slot 414 on the second side wall of the base 41. One end of the buckle spring 422 is pressed against a pressing member 44 in the base 42, and the other end presses against the U-shaped buckle 421. When one end of the U-shaped buckle 421 is pressed, the buckle spring 422 is squeezed, and the other end of the U-shaped buckle 421 can be released from the slot 414 of the base 41, thereby opening the base 42. The U-shaped buckle 421 comprises a vertical buckle body 4211, which fits against the inner surface of the second side wall of the base 42. A horizontal pressing post 4212, at one end of the U-shaped buckle 421, is movably mounted on the second side wall of the base 42 and vertically connected to one end of the vertical buckle body 4211. A horizontal locking post 4213, at the other end of the U-shaped buckle 421, has an inclined surface on the side of the horizontal locking post 4213 facing away from the vertical buckle body 4211. It movably locks into a slot 414 on the second side wall of the base 41 and vertically connects to the other end of the vertical buckle body 4211. In another example not shown, a slot is provided on the second side wall of the base 42, and a fastener is provided on the second side wall of the base 41. The fastener of the base 41 engages with the slot of the base 42. The structure of the fastener of the base 41 is identical to that of the base 42. The difference is that one end of the U-shaped buckle of the fastener of the base 41 is movably inserted into the second side wall of the base, and the other end can be engaged in the bayonet of the second side wall of the base cover. One end of the buckle spring is pressed onto the elastic support member 43 in the base 41. In a preferred example, the top wall of the base cover 42 has a through hole 423 just above the elastic support member 43 for convenient observation of the conveying progress. The area of the through hole 423 is smaller than the area of the elastic support member 43 to prevent the elastic support member 43 from falling out of the through hole 423. Alternatively, a baffle 4231 can be provided on the side of the through hole 423 to block the elastic support member 43 to prevent the elastic support member 43 from falling out of the through hole 423.

[0236] In another example not shown in the figure, the seat cover 42 has a third side wall and a fourth side wall arranged opposite to each other, adjacent to the first side wall and the second side wall of the seat cover 42, and the third side wall and the fourth side wall of the seat cover 42 respectively have cover openings for the transfemoral valve repair system to pass through at corresponding positions in the middle of the pressure piece 44.

[0237] In this example, the elastic support member 43 is placed in the hollow inner cavity 411 of the base 41. The elastic support members 43 of the first support clamp 40a and the second support clamp 40b are used to support the distal tube of the outer sheath structure and the adjustable bend tube of the adjustable bend structure of the transfemoral valve repair system, respectively. The upper part of the elastic support member 43 has a support column 431, which is located in the upper part of the hollow inner cavity 411 of the base 41; the support column 431 has a positive U-shaped groove 432 for engaging and supporting the transfemoral valve repair system in an axial direction. Two side stepped holes 433 are formed on both sides of the support column 431 in the base 41, and the two side stepped holes 433 can respectively accommodate the two pressure columns of the pressure member 44. In another example not shown in the figure, the elastic support member 43 has two parallel support blocks spaced a certain distance apart, which are located in the upper part of the hollow inner cavity 411 of the base 41; the two support blocks have a positive U-shaped groove for engaging and supporting the transfemoral valve repair system in an axial direction. A central stepped hole is formed in the base 41 between the support blocks. The central stepped hole can accommodate the pressing block of the pressing member 44 .

[0238] In this example, the lower portion of the elastic support member 43 comprises several pairs of support springs 434, which are located below the hollow inner cavity 411 of the base 41. The upper ends of the support springs 434 are connected to the lower surface of the support column 431, while the lower ends of the support springs 434 are connected to the lower surface of the hollow inner cavity 411 of the base 41. For example, a spring groove 435 or a spring boss (not shown) may be provided on the lower surface of the support column 431. The upper ends of the support springs 434 are embedded in the spring groove 435 of the support column 431 or are sleeved around the spring boss (not shown) of the support column 431. The lower surface of the hollow inner cavity 411 of the base 41 is provided with a spring boss 416 or a spring groove (not shown). The lower ends of the support springs 434 are sleeved around the spring boss 416 of the hollow inner cavity 411 of the base 41 or are embedded in the spring groove (not shown) of the hollow inner cavity 411 of the base 41.

[0239] In this example, the pressure piece 44 and the elastic support piece 43 are arranged in a staggered manner relative to each other. The pressure pieces 44 of the first support clamp 40a and the second support clamp 40b are respectively used to compress the distal tube of the outer sheath structure of the transfemoral valve repair system and the adjustable bend tube of the adjustable bend structure. The pressure piece 44 is two parallel pressure columns 441 spaced a certain distance apart. The upper ends of the pressure columns 441 are connected to the inner surface of the seat cover 42. The two pressure columns 441 are respectively located above the two sides of the support column 431 and located in the stepped holes 433 on both sides, thereby achieving a staggered arrangement to reduce the pressure of squeezing the transfemoral valve repair system. The pressure column 441 has an axially arranged inverted U-shaped groove 442 for engaging and squeezing the transfemoral valve repair system. The inverted U-shaped groove 442 of the pressure column 441 is opposite to the positive U-shaped groove of the support column 431, so that the two opposing U-shaped grooves can be docked to engage and compress the distal tube or the adjustable bend tube of the transfemoral valve repair system. In another embodiment (not shown), the pressure member 44 is a pressure block, the upper end of which is connected to the inner surface of the seat cover 42. The pressure block is positioned directly above the two support blocks and within the central stepped hole, thus achieving a staggered arrangement. The pressure block has an axially arranged inverted U-shaped groove for engaging and compressing the transfemoral valve repair system. The inverted U-shaped groove of the pressure block and the positive U-shaped groove of the support block face each other, allowing the two opposing U-shaped grooves to mate and compress the distal tube or adjustable elbow of the transfemoral valve repair system.

[0240] like Figures 7A to 7D As shown, in this example, the first support clamp 40a and the second support clamp 40b can be support clamps with the same structure as the sliding support clamp 50. The first support clamp 40a, the second support clamp 40b, and the sliding support clamp 50 respectively have a base 51, a clamping seat 52, and a locking member 53. The base 51 is the lower part of the support clamp. The base 51 of the support clamp 50 is slidably disposed in the sliding hole 311 of the wide section of the flat plate 31 of the slide 30. The base 51 has a work-shaped seat 511. The two sides of the work-shaped seat 511 respectively have symmetrically opposed U-shaped side grooves 512. The work-shaped seat 511 is slidably disposed in the sliding hole 311, and the two side walls of the sliding hole 311 are clamped in the U-shaped side grooves 512. The base 51 also has a column 513. The bottom of the column 513 is vertically and integrally connected to the upper surface of the work-shaped seat 511, and the top of the column 513 is fixedly connected to the lower surface of the clamping seat 52. The bottom of the column 513 is provided with a rod hole 514, into which a rod handle (not shown) can be inserted for gripping to push the support clamp 50. The work-shaped seat 511 has a T-shaped upper seat, and the bottom of the column 513 is vertically and integrally connected to the upper surface of the T-shaped upper seat; the work-shaped seat 511 also has a flat plate lower seat, which is connected to the lower end of the T-shaped upper seat, thereby forming the work-shaped seat 511. The base 51 of the first support clamp 40a and the second support clamp 40b is a column 513, and the bottom of the column 513 is provided at the distal end of the base plate 10 and the distal end of the slide 30. Because the support clamp 40a and the second support clamp 40b do not need to slide on the slide, the base 51 of the support clamp 40a and the second support clamp 40b does not need to be provided with a work-shaped seat.

[0241] In this example, the clamp seat 52, as the name implies, is used to clamp the transfemoral valve repair system. The clamp seat 52 is fixed on the base 51 and is integrally connected to the top of the column 513. The upper surface of the clamp seat 52 is recessed with an axial clamping groove 521, which is roughly a U-shaped groove. Specifically, the axial clamping groove 521 can be used to clamp the delivery tube 210 of the delivery structure 200 of the transfemoral valve repair system. The side wall of the clamp seat 52 has a lock hole cavity that passes through the side wall. The function of the lock hole cavity is to accommodate the locking element 53 and the inner end of the locking element 53 is squeezed on the delivery tube 210 of the delivery structure 200 of the transfemoral valve repair system to achieve a locking function. The lock hole cavity has a cavity body 5221, which is arranged in the side wall of the clamp seat 52; the radial area of the inner hole 5222 is smaller than the cavity body 5221, and the two ends are respectively connected with the axial clamping groove 522 and the cavity body 5221, so that the inner end of the lock piece 53 can pass through the inner hole 5222 and be squeezed on the conveying pipe; the two spring holes 5223 are symmetrically extended from the axial sides of the cavity body 5221, are axially parallel to and connected with the cavity body 5221, and are axially staggered with the inner hole 5222.

[0242] In this example, the locking element 53 is radially penetrated on the side wall of the clamp seat 52, and the locking element 53 has an inner end that can clamp the delivery tube of the transfemoral valve repair system. The locking element 53 has an elastic locking block, a side cover 532 and a push button 533 from the inside to the outside, so that the inner end of the locking element 53 is the elastic locking block. The elastic locking block is axially movable and arranged in the lock hole cavity of the clamp seat 52; the side cover 532 is attached to the outside of the side wall of the clamp seat 52, sealing the elastic locking block in the lock hole cavity; the push button 533 is axially movable through the side cover 532, and the inner end of the push button 533 abuts against the elastic locking block, so that the inner end of the elastic locking block can clamp the delivery tube 210 of the transfemoral valve repair system. The elastic locking block has a block body 5311, which is arranged in the cavity body 5221 of the lock hole cavity of the clamp seat 52, and the inner end of the block body 5311 can freely move through the inner hole 5222 of the lock hole cavity; the two spring blocks 5312 are symmetrically connected to the axial circumferential wall of the block body 5311 and close to the outer end, and the spring blocks 5312 are located on the outside of the spring hole 5223 of the lock hole cavity; the two locking springs 5313 are located in the spring hole 5223 of the lock hole cavity, one end of the locking spring 5313 rests on the inner wall of the lock hole cavity, and the other end rests on the spring block 5312, so as to push the elastic locking block away so that the block body 5311 no longer squeezes the delivery tube of the transfemoral valve repair system, so that it is separated from the transfemoral valve repair system. The side cover 532 is fixed to the side wall of the clamping base 52 by bolts. A threaded hole 5321 is formed in the middle of the side cover 532. A stud 5331 is formed in the middle of the push button 533. The stud 5331 of the push button 533 passes through the threaded hole 5321 of the side cover 532, and the inner end of the stud 5331 abuts against the elastic locking block, so that the elastic locking block can clamp the delivery tube of the transfemoral valve repair system. Due to the provision of the locking spring 5313 and the action of the push button 533, when the push button 533 is tightened, the inner end of the block body 5311 abuts against the delivery tube, thereby locking it. When the push button 533 is rotated in the opposite direction, the reaction of the locking spring 5313 causes the block body 5311 to move away from the delivery tube, thereby unlocking it.

[0243] The support frame further comprises a distal frame 60, which includes a frame post 61, the bottom of which is fixed to the distal end of the base plate 10. The distal frame 60 has a handle slot 62 with an upwardly opening arcuate groove on the frame post 61. The handle slot 62 can support the sheath handle of the outer sheath structure of the transfemoral valve repair system. The support frame further comprises an intermediate frame 70, which also includes a short frame post 71 and a housing slot 72 with an upwardly opening arcuate groove on the short frame post 71. The bottom of the short frame post 71 is fixed to the middle portion of the flat plate 31 of the slide 30. The housing slot 72 can support the bendable housing of the bendable structure of the transfemoral valve repair system.

[0244] With this design, the delivery structure 200 (having a delivery tube 210 and a delivery handle 220), the adjustable bend structure 300 (having a bend adjustment shell 324 and an adjustable bend tube 310), and the outer sheath structure 500 of the entire transfemoral valve repair system are all supported and clamped by the support frame. Each part can be operated as needed instead of being randomly placed, which is convenient for medical staff to operate.

[0245] like Figure 8 FIG2 is a schematic diagram of the three-dimensional structure of another exemplary support frame according to the present invention. This support frame is primarily designed to better control the clamping force between the support clip, the distal end of the outer sheath structure of the transfemoral valve repair system, and the adjustable bend of the adjustable bend structure. The support clip is designed to be controlled by a thread, similar to the structure of the sliding support clip 50.
