SYSTEMS AND DELIVERY HANDLES FOR DELIVERING PROSTHETIC HEART VALVES DISPOSED ON VALVE HOLDERS
First Claim
1. A system for delivering a prosthetic heart valve comprising:
- a delivery handle including a rod, a button, and a valve holder attachment interface, the button configured to move between a first position and a second position along an axial length of the rod, and the valve holder attachment interface mechanically coupled to the button and configured to move between an engaged position and a disengaged position;
a prosthetic heart valve; and
a valve holder coupled to the heart valve, the valve holder including a boss, a holder ring, and a handle attachment interface, the holder ring including the heart valve mounted thereto and coupled to the boss, and the handle attachment interface formed on the boss and configured to receive and mate with the valve holder attachment interface,wherein;
when the button is in the first position, the valve holder attachment interface is in the engaged position to mechanically couple to the handle attachment interface, andwhen the button is moved to the second position, the valve holder attachment interface moves correspondingly to the disengage position to mechanically release from the handle attachment interface.

Abstract
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.

15. A delivery handle for delivering a prosthetic heart valve disposed on a valve holder, the delivery handle comprising:
-
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; and at least two 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, wherein; when the button is in the first position, the at least 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 at least two prongs rotate at the pivot point on the shaft to an expanded position to mechanically release from the valve holder. - View Dependent Claims (16)

17. A delivery handle for delivering a prosthetic heart valve disposed on a valve holder, the delivery handle comprising:
-
a rod; a hollow shaft through which the rod extends having an axial length and a slit along a portion of the axial length; a valve holder attachment interface comprising a stem and a hook, the stem disposed between the rod and the hollow shaft, and the hook extending at least partially outside of the shaft; and a button coupled to the stem. extending out of the slit of the hollow shaft, and configured to move along the axial length of the rod from a first position to a second position, wherein; when the button is in the first position, the hook is disposed in a retracted position to mechanically engage an attachment interface on the valve holder, and when the button is in the second position, the hook is in a lengthened position to mechanically release from the attachment interface on the valve holder. - View Dependent Claims (18, 19)

20. A delivery handle for delivering a prosthetic heart valve disposed on a valve holder, the delivery handle comprising:
-
a rod; a hollow shaft through which the rod extends having an axial length and a slit extending along a portion of the axial length; a valve holder attachment interface including a cylinder and at least two prongs, the cylinder disposed between the rod and the hollow shaft, and the at least two prongs spaced apart and extending from the cylinder and configured to expand and contract relative to each other; and a button coupled to a portion of the cylinder and extending through the slit to move from a first position to a second position, wherein; when the button is in the first position, the at least two prongs expand relative to each other to mechanically couple to an attachment interface on the valve holder, and when the button is in the second position, the at least two prongs contract relative to each other to mechanically release from the attachment interface on the valve holder. - View Dependent Claims (21, 22)
