COLLAPSIBLE PROSTHETIC HEART VALVES |
摘要 |
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. |

1. A prosthetic heart valve comprising:
an annularly collapsible and re-expandable supporting structure extending between an inflow end and an outflow end; a plurality of leaflets disposed inside the supporting structure; and a lower skirt disposed adjacent the inflow end of the supporting structure, the lower skirt including a single continuous sheet that extends from a luminal surface of the supporting structure, wraps around the inflow end and extends over a portion of the abluminal surface of the supporting structure, wherein the lower skirt includes a first portion disposed on the luminal surface of the supporting structure and a second portion disposed on the abluminal surface of the supporting structure and the first portion and the second portion are coupled together at a top edge of the second portion. |
