1. :
- A valve prosthesis comprising;
a valve body including a plurality of valve leaflets affixed to a skirt; and
a frame including a distal inflow section, a proximal outflow section, and a valve section between the inflow section and the outflow section, wherein;
the valve body is attached to the frame in the valve section at a plurality of commissure points,the frame includes a circumferentially repeating cell pattern in the inflow section and the valve section,the outflow section includes a plurality of loops, the plurality of loops being attached to the valve section at a plurality of junctions, anda plurality of circumferentially adjacent valve section cells are positioned entirely between a junction and a circumferentially adjacent junction of the plurality of junctions in a circumferential direction.

Abstract
Heart valve prostheses are provided having a self-expanding frame that supports a valve body comprising a skirt and a plurality of coapting leaflets. The self-expanding frame includes an inflow section, a valve section, and an outflow section. The outflow section forms attachment loops in a collapsed configuration to attach the frame to a delivery system.
