TIP FOR MEDICAL IMPLANT DELIVERY SYSTEM

摘要

A delivery system for delivering and deploying a medical implant, such as a prosthetic heart valve, includes an elongated support member (28), a sheath (30), and a tip (132). The sheath is movable relative to the elongated support member between a distal position overlying the medical implant and a proximal position exposing the medical implant for release from the delivery system. The tip is attached to the elongated support member and is positioned at a distal end of the sheath when the sheath is in the distal position. The tip has a compressed condition and an expanded condition, and a maximum diameter in the expanded condition that is larger than the outer diameter of the sheath.
