1. A valve having a proximal end and a distal end, the valve comprising:
- an expandable valve body extending from the proximal end to the distal end of the valve, the valve body defining a lumen; and
an obstructer retained between the proximal and distal ends of the valve and within the lumen of the valve body when the valve is in an expanded configuration, the obstructer longitudinally moveable within the lumen;
the valve body being an expandable mesh, the expandable mesh including end loops at the distal end of the expandable valve body, the one end of the expandable valve body further comprising an end ring interconnecting the end loops, the end ring defining an end lumen opening.

Abstract
A valve that includes an expandable valve body defining a lumen and a longitudinally moveable obstructer retained within the lumen of the valve body between the proximal and distal ends of the valve when the valve is in an expanded configuration. The valve, in the collapsed configuration, is delivered to a native valve site by a catheter where the valve body is expanded to anchor the valve at the valve annulus and the collapsed obstructer is subsequently expanded so that the valve is in the expanded configuration.

13. A valve having a proximal end and a distal end, the valve comprising:
-
an expandable valve body extending from the proximal end to the distal end of the valve, the valve body defining a lumen; and an expandable obstructer; the valve having an expanded configuration wherein the expandable valve body is in an expanded state and the obstructer is in an expanded state, wherein the obstructer in the expanded state is retained between the proximal and distal ends of the valve and within the lumen of the valve body, the obstructer longitudinally moveable within the lumen; the valve having a collapsed configuration wherein the expandable valve body is in a collapsed state and the obstructer is in a collapsed state; the valve in combination with a catheter, the valve being in the collapsed configuration, the catheter comprising; a tubular outer sheath defining an outer lumen; a tubular intermediate shaft defining an intermediate lumen, the tubular intermediate shaft positioned within the outer lumen; and a tubular inner shaft defining an inner lumen, the inner shaft positioned within the intermediate lumen; the outer sheath, the intermediate shaft, and the inner shaft being longitudinally moveable relative to one another; wherein the valve body is positioned within the outer lumen and the obstructer is releasably engaged to the tubular inner shaft and the obstructer is proximal to the expandable valve body. - View Dependent Claims (14)
