Abstract

Stent-valves (e.g., single-stent-valves and double-stent-valves), associated methods and systems for their delivery via minimally-invasive surgery, and guide-wire compatible closure devices for sealing access orifices are provided.

Claims

1. A replacement valve for use within a human body comprising:

a valve component; and

a stent component comprising;
