Abstract: Aspects of the disclosure generally relate to systems and methods for transcatheter delivery of an implant, such as a prosthetic heart valve, to a target site. Such systems can include a delivery system and an implant having a brim secured to an anchoring member. Systems and methods of the disclosure can include everting the brim of the prosthetic heart valve so that the everted brim and a capsule of the delivery system collectively sheathe the anchoring member of the prosthetic heart valve during delivery of the prosthetic heart valve to the target site.

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.
