Balloon release mechanism for tavi implant

Abstract

A delivery system for an implantable medical device having at least one retention member at an end thereof includes a shaft extending in a longitudinal direction. An elongated sheath surrounds the shaft. The sheath is slidable relative to the shaft in the longitudinal direction. A space is defined inside of the sheath and is adapted to receive the medical device in an assembled or collapsed condition. A retainer is positioned at a first end of the space. At least one recess is provided in the retainer and is adapted to receive the retention member of the medical device in the assembled condition. A selectively activable member is disposed in the compartment between the longitudinal shaft and the medical device. When in an activated state, the member expands radially relative to the shaft, thereby urging the retention member to disengage from the recess.

Dependencies are inferred from the claim text.
