SYSTEMS AND METHODS FOR RETRIEVING SIDE-DELIVERABLE TRANSCATHETER PROSTHETIC VALVES

WIPO Patent Application WO/2023/164489

A3

A delivery/retrieval system includes a control device and a retrieval element. The control device is removably coupleable to a side-deliverable prosthetic valve and is operable to (i) exert a distally directed force to advance the compressed valve through a delivery sheath and into a chamber of the heart and (ii) exert a proximally directed force to pull the expanded valve from the chamber of the heart into a retrieval sheath. A proximal end portion of the retrieval element is coupleable to a proximal end portion of the control device. A distal end portion of the retrieval element forms an engagement member operable to engage and exert a proximally directed force on a proximal subannular anchoring element of the valve to pull the valve into the retrieval sheath. A guide member is operable to guide at least one edge of the valve as it is pulled into the retrieval sheath.
