Transcatheter heart valve prosthesis assembled inside heart chambers or blood vessels
Some embodiments described herein include a heart valve replacement system that may be delivered to the targeted heart valve site via a delivery catheter. In some embodiments, the heart valve replacement system can assemble a valve device after the valve device is delivered to the heart. In some embodiments, heart valve replacement system includes two anterior flaps that are separate but overlap each other.
1. A prosthetic tricuspid valve comprising:
a main body comprising an occluder having valve leaflets;
a first anterior flap extending laterally from an end of the main body; and
a second anterior flap extending laterally from the end of the main body in a same direction as the first anterior flap,
wherein portions of the first anterior flap and the second anterior flap overlap each other when the prosthetic tricuspid valve is deployed, and
wherein having the portions of the first anterior flap and the second anterior flap that overlap each other increases a bending resistance of the first anterior flap and the second anterior flap in combination as compared to the first anterior flap and the second anterior flap individually.
2. The prosthetic tricuspid valve of claim 1 , further comprising a posterior flap extending laterally from the end of the main body in an opposite direction as the first and second anterior flaps.
3. The prosthetic tricuspid valve of claim 2 , wherein the first and second anterior flaps extend farther laterally than the posterior flap.
4. The prosthetic tricuspid valve of claim 3 , wherein the first and second anterior flaps in combination are wider than the posterior flap.
5. The prosthetic tricuspid valve of claim 2 , wherein a framework of the prosthetic tricuspid valve that comprises the main body, the first and second anterior flaps, and the posterior flap is made of a single, unitary material that was cut and expanded.
6. The prosthetic tricuspid valve of claim 2 , wherein a distal tip portion of the posterior flap extends along an axis that is at a non-zero angle relative to a portion of the posterior flap that extends directly from the main body.
7. The prosthetic tricuspid valve of claim 1 , wherein having the portions of the first anterior flap and the second anterior flap as separate members configure the prosthetic tricuspid valve to have a pacemaker lead pass through the prosthetic tricuspid valve between the first and second anterior flaps.
8. The prosthetic tricuspid valve of claim 1 , further comprising one or more additional anterior flaps extending laterally from the end of the main body in the same direction as the first and second anterior flaps.
9. The prosthetic tricuspid valve of claim 1 , further comprising two or more posterior flaps extending laterally from the end of the main body in an opposite direction as the first and second anterior flaps.
10. The prosthetic tricuspid valve of claim 1 , further comprising a deployment system comprising:
a sheath catheter defining a first lumen;
an outer proximal catheter slidably disposed within the first lumen and defining a second lumen; and
an inner distal catheter slidably disposed within the second lumen,
wherein the prosthetic tricuspid valve is disposed within the first lumen in a low profile delivery configuration and is releasably attached to both the outer proximal catheter and the inner distal catheter.
11. The prosthetic tricuspid valve of claim 10 , wherein the main body is releasably attached to outer proximal catheter, and wherein the first and second anterior flaps are releasably attached to the inner distal catheter.
12. The prosthetic tricuspid valve of claim 11 , wherein the prosthetic tricuspid valve further comprises a posterior flap extending laterally from the end of the main body in an opposite direction as the first and second anterior flaps, and wherein the posterior flap is disposed within the first lumen while not being directly attached to the deployment system.
13. The prosthetic tricuspid valve of claim 11 , wherein the first and second anterior flaps are individually releasably attached to the inner distal catheter.
14. A prosthetic tricuspid valve comprising:
a main body comprising an occluder having valve leaflets;
a first anterior flap extending laterally from an end of the main body; and
a second anterior flap extending laterally from the end of the main body in a same direction as the first anterior flap,
wherein having the portions of the first anterior flap and the second anterior flap as separate members configure the prosthetic tricuspid valve to have a pacemaker lead pass through the prosthetic tricuspid valve between the first and second anterior flaps.
15. The prosthetic tricuspid valve of claim 14 , wherein portions of the first anterior flap and the second anterior flap overlap each other.
16. The prosthetic tricuspid valve of claim 15 , wherein having the portions of the first anterior flap and the second anterior flap that overlap each other increases a bending resistance of the first anterior flap and the second anterior flap in combination as compared to the first anterior flap and the second anterior flap individually.
17. The prosthetic tricuspid valve of claim 14 , further comprising a posterior flap extending laterally from the end of the main body in an opposite direction as the first and second anterior flaps.
18. The prosthetic tricuspid valve of claim 17 , wherein the first and second anterior flaps in combination are wider than the posterior flap.
19. A prosthetic tricuspid valve comprising:
a main body comprising an occluder having valve leaflets;
a first anterior flap extending laterally from an end of the main body;
a second anterior flap extending laterally from the end of the main body in a same direction as the first anterior flap; and
two or more posterior flaps extending laterally from the end of the main body in an opposite direction as the first and second anterior flaps.
20. The prosthetic tricuspid valve of claim 19 , wherein portions of the first anterior flap and the second anterior flap overlap each other.
21. The prosthetic tricuspid valve of claim 20 , wherein having the portions of the first anterior flap and the second anterior flap that overlap each other increases a bending resistance of the first anterior flap and the second anterior flap in combination as compared to the first anterior flap and the second anterior flap individually.
22. The prosthetic tricuspid valve of claim 19 , wherein having the portions of the first anterior flap and the second anterior flap as separate members configure the prosthetic tricuspid valve to have a pacemaker lead pass through the prosthetic tricuspid valve between the first and second anterior flaps.
