First Claim
Patent Images
1. A prosthetic heart valve comprising:
- an annularly collapsible and re-expandable supporting structure extending between an inflow end and an outflow end, the supporting structure including a plurality of struts;
a plurality of leaflets disposed inside the supporting structure;
a cuff disposed on a surface of the supporting structure;
a plurality of commissure features for attaching the leaflets to the supporting structure;
a plurality of first eyelets disposed on the supporting structure, the first eyelets being disposed adjacent the inflow end at a position farthest from the outflow end, and spaced from the plurality of commissure features, selected ones of the plurality of first eyelets being coupled to the cuff.

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.
