Abstract
Aspects of the disclosure provide a cardiac implant delivery device including catheter having a distal end and a telescoping capsule assembly secured to the distal end. The capsule assembly can include a distal capsule and a proximal capsule. Other embodiments include additional capsules positioned between the proximal and distal capsules. The capsule assembly has a loaded arrangement and a deployed arrangement. As the capsule assembly transitions from the loaded arrangement fully covering the implant to the deployed arrangement, the proximal capsule and any intermediate capsules move distally in the direction of the distal capsule to unsheathe the implant. In various embodiments, the cardiac implant is a prosthetic heart valve. Methods of delivering a cardiac implant are also disclosed. Various methods include methods of delivering a replacement tricuspid heart valve.
