Abstract: A delivery system for prosthetic heart valves are provided. The delivery system includes a flexible shaft, a distal sheath capsule configured to contain the prosthetic heart valve, an inner steerable catheter including an inner distal flex component, and an outer steerable catheter including an outer distal flex component. The inner distal flex component includes a first cut pattern and a second cut pattern distal to the first cut pattern. The outer distal flex component includes a third cut pattern. The inner steerable catheter is rotatable at least 90 degrees relative to the outer steerable catheter when the third cut pattern of the outer distal flex component is disposed over at least a portion of the first cut pattern of the inner distal flex component and each of the inner steerable catheter and the outer steerable catheter is in the flexed configuration.

Abstract: A prosthesis having a radially expanded configuration and a radially compressed configuration includes a frame with a plurality of infolding longitudinal segments. Each of the infolding longitudinal segments of the frame extend an entire length of the frame and is configured to deform radially inward when the prosthesis is in the radially compressed configuration such that a series of longitudinally aligned apices of each infolding longitudinal segment is disposed radially inward of the remainder of the prosthesis. In an embodiment, the frame also includes a plurality of outfolding longitudinal segments. Each of the outfolding longitudinal segments of the frame extend an entire length of the frame and is configured to deform radially outward when the prosthesis is in the radially compressed configuration such that a series of longitudinally aligned apices of each outfolding longitudinal segment is disposed radially outward of the remainder of the prosthesis.

Abstract: Heart valve prosthesis are disclosed that include a frame or support structure having an inflow portion, a valve-retaining tubular or central portion and a pair of support arms. The inflow portion radially extends from a first end of the valve-retaining tubular portion and the pair of support arms are circumferentially spaced apart and radially extend from an opposing second end of the valve-retaining tubular portion.
