SYSTEMS AND DELIVERY HANDLES FOR DELIVERING PROSTHETIC HEART VALVES DISPOSED ON VALVE HOLDERS

摘要

A system delivering a prosthetic heart valve includes a delivery handle, a heart valve, and a valve holder. The delivery handle includes a rod, a button, and a valve holder attachment interface, where the button is configured to move between a first position and a second position along an axial length of the rod, and the valve holder attachment interface is mechanically coupled to the button and configured to move between an engaged position and a disengaged position. The heart valve includes a prosthetic valve. The valve holder is connected to a proximal end of the heart valve and includes a boss, a holder ring, and a handle attachment interface. The holder ring includes the heart valve mounted thereto and is coupled to the boss, and the handle attachment interface is formed on the boss and is configured to receive and mate with the valve holder attachment interface.

1. A system for delivering a prosthetic heart valve, comprising:
a delivery handle including;
a rod;a shaft disposed on a distal end of the rod and having an axial slit;a button extending through the axial slit and configured to move along a portion of a length of the axial slit between a first position and a second position, the button including a slot; andtwo prongs each having a stem extending from a proximal end of the prong, the stem extending through the slot of the button and rotationally coupled to the shaft to provide a pivot point, a prosthetic heart valve; and a valve holder coupled to the heart valve including a handle attachment interface configured to receive and mate with the valve holder attachment interface; wherein: when the button is in the first position, the two prongs are in a contracted position for mechanically coupling to the valve holder, and when the button is moved to the second position, the two prongs rotate at the pivot point on the shaft to an expanded position to mechanically release from the valve holder.
