1. A system, comprising:
- an elongate delivery catheter;
an elongate mesh body including an expandable region positioned around at least a portion of the elongate delivery catheter;
a retractable member that extends through the elongate delivery catheter to connect to the elongate mesh body, where the retractable member moves to radially expand the expandable region of the elongate mesh body from an undeployed state to an intermediate state;
a valve positioned around at least a portion of the elongate delivery catheter position; and
a filter positioned around at least a portion of the elongate delivery catheter.

Abstract
A system having an elongate delivery catheter, an elongate mesh body including an expandable region positioned around at least a portion of the elongate delivery catheter, a retractable member that extends through the elongate delivery catheter to connect to the elonga'"'"'te mesh body, where the retractable member moves to radially expand the expandable region of the elongate mesh body from an undeployed state to an intermediate state. The system also includes a valve positioned around at least a portion of the elongate delivery catheter position, and a filter positioned around at least a portion of the elongate delivery catheter to filter and control fluid flow.

11. A system, comprising:
-
an elongate delivery catheter; an elongate mesh body including an expandable region positioned around at least a portion of the elongate delivery catheter; a retractable member that extends through the elongate delivery catheter to connect to the elongate mesh body; a valve positioned around at least a portion of the elongate delivery catheter; a filter positioned around at least a portion of the elongate delivery catheter; and an inflatable balloon coupled to an inflation lumen that extends through the elongate delivery catheter, the inflatable balloon positioned around at least a portion of the elongate delivery catheter between the elongate delivery catheter and the elongate mesh body, where the inflatable balloon expands to transition the expandable region from a delivery state to an intermediate state, and the expandable region expands from the intermediate state to a deployed state when the retractable member moves a distal end of the elongate mesh body towards a proximal end of the elongate mesh body. - View Dependent Claims (12, 13, 14)

15. A method, comprising:
-
positioning an elongate filter body around a portion of an elongate delivery catheter; joining a valve structure to the elongate filter body to form a path through which fluid can flow and be filtered by the elongate filter body; positioning an elongate mesh body having an expandable region around at least a portion of the elongate delivery catheter distal to the elongate filter body and the valve structure; and placing a prosthetic valve over the expandable region of the elongate mesh body, where the expandable region radially expands to at least partially deploy the prosthetic valve. - View Dependent Claims (16, 17, 18, 19)
