Abstract: Delivery catheters for delivery of prosthetic heart valves are provided. The delivery catheters include brim recapture funnels configured for recapture of prosthetic heart valves. The brim recapture funnels are configured to recapture valve brims of partially deployed prosthetic heart valves to reduce or minimize damage to patient anatomy during a valve withdrawal procedure. Brim recapture funnels as described herein may be activated via suture control.

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.
