Collapsible prosthetic heart valves
First Claim
Patent Images
1. A prosthetic heart valve, comprising:
- a stent having an inside, an outside, an inflow end with an inflow edge, an outflow end, a collapsed condition and an expanded condition, the stent extending in a longitudinal direction between the inflow end and the outflow end;
a valve element mounted within the stent; and
a structure having an inside wall on the inside of the stent and an outside wall on the outside of the stent, the structure including a single layer of material extending around the inflow edge from the inside wall to the outside wall, the inside wall having a first length in the longitudinal direction and the outside wall having a second length in the longitudinal direction less than the first length.

Abstract
Prosthetic heart valves, which are collapsible to a relatively small circumferential size for less invasive delivery into a patient and which then re-expand to operating size at an implant site in the patient, include a collapsible/expandable stent-like supporting structure and various components of flexible, sheet-like material that are attached to the supporting structure. For example, these sheet-like other components may include prosthetic valve leaflets, layers of buffering material, cuff material, etc. Improved structures and techniques are provided for securing such other components to the stent-like supporting structure of the valve.

17. A prosthetic heart valve, comprising:
-
a stent having an inside, an outside, a proximal end at an inflow end with an inflow edge, a distal end at an outflow end, a collapsed condition and an expanded condition, the stent having a length from the inflow end to the outflow end; a valve element mounted within the stent so as to define a plurality of pockets on the inside of the stent, each of the pockets having an inner pocket wall and an outer pocket wall, the plurality of pockets residing at a predetermined position along the length of the stent; and a structure extending around a periphery of the stent and having an inside wall on the inside of the stent and an outside wall on the outside of the stent, the inside wall being connected to the stent, the structure extending around the inflow edge from the inside wall to the outside wall and including at least one opening at the periphery of the stent, the opening being located at the predetermined position along the length of the stent and radially outward of at least one of the outer pocket walls, a distal end of the structure being positioned proximally of the distal end of the stent. - View Dependent Claims (18, 19, 20, 21, 22)

23. A prosthetic heart valve, comprising:
-
a stent having an inside, an outside, an inflow end with an inflow edge, an outflow end, a collapsed condition and an expanded condition, the stent having a length from the inflow end to the outflow end; a valve element mounted within the stent, the valve element including a plurality of pockets disposed on the inside of the stent, each of the pockets having an inner pocket wall and an outer pocket wall; and a structure extending around a periphery of the stent and having an inside wall on the inside of the stent and an outside wall on the outside of the stent, the inside wall being connected to the stent, the structure extending around the inflow edge from the inside wall to the outside wall and including at least one opening at the periphery of the stent, the opening being located radially outward of at least one of the pockets, the pockets and the opening each having a portion positioned an equal longitudinal distance from the inflow edge of the stent. - View Dependent Claims (24, 25, 26, 27)
