Claims
- 1. A prosthetic heart valve system comprising:
a prosthetic heart valve including a stent and a plurality of stent posts extending from the stent, each of the stent posts defining a free end; and a deflection device for inwardly deflecting the stent post, the deflection device including:
a line interconnecting and passing through the free ends of the stent post, a connector assembly including a tensioning component connected to the line and transitionable to a tensioning state in which the tensioning component transitions the line to inwardly deflect the stent post, the connector assembly being adapted such that the tensioning component is self-locking relative to the line in the tensioning state; wherein an entirety of the line extending distal the tensioning device in the tensioning state does not extend beyond the stent opposite the free ends.
- 2. The prosthetic heart valve system of claim 1, further comprising:
a holder having a holder body coupled to the prosthetic heart valve.
- 3. The prosthetic heart valve system of claim 2, wherein the holder includes a holder body coupled to the prosthetic heart valve, the holder body configured to selectively retain the tensioning component.
- 4. The prosthetic heart valve system of claim 3, wherein the tensioning component includes a tubular body slidably connected to the line, and further wherein the holder body defines an aperture sized to selectively retain the tubular body.
- 5. The prosthetic heart valve system of claim 4, wherein the aperture is sized to receive the tubular body via a snap fit.
- 6. The prosthetic heart valve system of claim 2, wherein the holder body and the tensioning device are separately coupled to the prosthetic heart valve.
- 7. The prosthetic heart valve system of claim 6, wherein the holder body forms a central passage, and further wherein upon final assembly, the tensioning. component is accessible via the central passage.
- 8. The prosthetic heart valve system of claim 7, wherein the tensioning component includes a rotatable spool including a post, and further wherein upon final assembly, the post is aligned with the central passage.
- 9. The prosthetic heart valve system of claim 8, wherein the post is engageable with a handle device.
- 10. The prosthetic heart valve system of claim 8, wherein the connector assembly further includes a ratchet along rotation of the spool only to wind the line around the spool.
- 11. The prosthetic heart valve system of claim 10, wherein the ratchet is accessible via the central passage.
- 12. The prosthetic heart valve system of claim 1, wherein the connector assembly is assembled to the line such that the line defines a loop distal the connector assembly, the loop interconnecting the stent post.
- 13. The prosthetic heart valve system of claim 12, wherein a length of the loop in a locked state is selected to provide a predetermined amount of inward deflection of the stent post.
- 14. The prosthetic heart valve system of claim 1, wherein the connector assembly includes:
a housing defining a proximal end, a distal end, and a central passage, wherein the line is slidably received within the central passage; and a locking element secured to the line at a fixed location so as to define a loop in the line adapted to interconnect the stent post; wherein the housing and the locking element are configured such that the locking element is slidably receivable within the central passage at the distal end and locks to the housing adjacent the proximal end thereof to define a locked state.
- 15. The prosthetic heart valve system of claim 14, wherein the distal end of the housing extends distal the locking element in the locked state such that in the locked state, a length of the loop distal the connector assembly is defined by the distal end of the housing.
- 16. The prosthetic heart valve system of claim 1, wherein the connector assembly further includes a strip of material extending from the line, the strip of material providing a plurality of locking surfaces each adapted to lock the tensioning device relative to the line.
- 17. The prosthetic heart valve system of claim 1, wherein the prosthetic heart valve is a prosthetic mitral valve.
- 18. The prosthetic heart valve system of claim 1, wherein the prosthetic heart valve is a prosthetic aortic valve.
- 19. A prosthetic heart valve system comprising:
a prosthetic heart valve including a stent and a plurality of stent posts extending from the stent, each of the stent posts defining a free end; a holder including a holder body coupled to the prosthetic heart valve; and a deflection device including a tensioning component coupled to the prosthetic heart valve apart from the holder body.
- 20. The prosthetic heart valve system of claim 19, further comprising:
a first line coupling the holder body to the prosthetic heart valve; and a second line coupling the tensioning component to the prosthetic heart valve.
- 21. The prosthetic heart valve system of claim 20, wherein the system is adapted such that severing of the first line does uncouple the tensioning component from the prosthetic heart valve.
- 22. The prosthetic heart valve system of claim 19, wherein the system is adapted such that upon uncoupling of the holder body from the prosthetic heart valve, the tensioning component remains coupled to the prosthetic heart valve.
- 23. The prosthetic heart valve system of claim 19, wherein the tensioning component is selectively maintained by the holder body.
- 24. The prosthetic heart valve system of claim 23, wherein the tensioning device includes a housing, and further wherein the holder body forms an aperture sized to selectively maintain the housing.
- 25. The prosthetic heart valve system of claim 19, wherein the holder body and the tensioning device are separately coupled to the prosthetic heart valve.
- 26. The prosthetic heart valve system of claim 25, wherein the holder body forms a central passage, and further wherein upon final assembly, the tensioning component is accessible via the central passage.
- 27. The prosthetic heart valve system of claim 26, wherein the tensioning component includes a rotatable spool including a post, and further wherein upon final assembly, the post is aligned with the central passage.
- 28. The prosthetic heart valve system of claim 27, wherein the post is engageable with a handle device.
- 29. The prosthetic heart valve system of claim 27, wherein the connector assembly further includes a ratchet along rotation of the spool only to wind the line around the spool.
- 30. The prosthetic heart valve system of claim 29, wherein the ratchet is accessible via the central passage.
- 31. The prosthetic heart valve system of claim 19, wherein the prosthetic heart valve is a prosthetic mitral valve.
- 32. The prosthetic heart valve system of claim 19, wherein the prosthetic heart valve is a prosthetic aortic valve.
