1. A filter system, comprising:
- an elongate filter body including an expandable filter region defining a lumen; and
a valve defining a lumen and having a reversibly sealable opening for unidirectional flow of a fluid through the lumen, the valve adjoined the expandable filter region of the elongate filter body, wherein the expandable filter region filters the unidirectional flow of the fluid passing through the lumen of the valve and the lumen of the expandable filter region.

Abstract
A filter system, comprising an elongate filter body defining a lumen and having a proximal end and a distal end. A valve can be provided defining a lumen and having a reversibly sealable opening for unidirectional flow of a fluid through the lumen. The valve can be adjoined proximal the distal end of the elongate filter body, wherein the elongate filter body filters the unidirectional flow of the fluid passing through the lumen of the valve and the lumen of the elongate filter body.

25. A system, comprising:
-
an elongate filter body including an expandable filter region, the elongate filter body and the expandable filter region defining a lumen and having a proximal end and a distal end;
a first cutting head having a blade and an elongate pulling member, the first cutting head positioned proximal the distal end of the elongate body with the elongate pulling member extending through a first lumen of a catheter, wherein the elongate pulling member slides within the first lumen to move the first cutting head relative the distal end of the elongate body;
a second cutting head having a blade, the second cutting head positioned adjacent the distal end of the elongate body between the distal end and the first cutting head, where the blade of the first cutting head moves relative the blade of the second cutting head to provide a shearing action for cardiac tissue, wherein the catheter extends though the lumen of the elongate filter body and the lumen of the valve;
a second lumen of a catheter extending between the proximal end and the distal end of the elongate body;
the inflatable balloon positioned adjacent the distal end of the elongate body and proximal to the second cutting head, the inflatable balloon in fluid tight communication with the second lumen;
a cardiac valve including a reversibly sealable opening for unidirectional flow of a liquid through a lumen of the cardiac valve, the cardiac valve releasably positioned over the inflatable balloon; and
the expandable stent positioned over at least a portion of the inflatable balloon, where the inflatable balloon deploys the cardiac valve and expandable stent over sheared cardiac tissue. - View Dependent Claims (26)

27. A method, comprising:
-
providing an elongate filter body including an expandable filter region defining a lumen;
providing a valve defining a lumen and having a reversibly sealable opening for unidirectional flow of a fluid through the lumen; and
adjoining the valve to the elongate filter region to form a single lumen through which the fluid flows through the valve and the elongate filter region to filter the fluid. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36)
