HEART VALVE DELIVERY SYSTEM WITH VALVE CATHETER
First Claim
1. A device for treating a human heart, comprising:
- an expandable prosthetic valve;
a tubular delivery sleeve having a proximal end;
a lead screw nut coupled to the proximal end of the tubular delivery sleeve;
a valve catheter having a distal end coupled to a mop comprising a plurality of flexible extensions configured for releasable attachment to the prosthetic valve, wherein the valve catheter and the prosthetic valve are slidably advanceable through the delivery sleeve; and
a lead screw coupled to the valve catheter;
wherein the lead screw engages the lead screw nut and wherein rotation of the lead screw causes the delivery sleeve to retract relative to the valve catheter and the prosthetic valve for exposing the prosthetic valve and extensions and allowing expansion of the valve and the flexible extensions of the mop allow expansion of the valve while maintaining the attachment with the valve during adjustment of the valve at a native valve site.

Abstract
A heart valve delivery system is provided wherein a prosthetic valve is carried on a valve catheter inside a tubular delivery sleeve. The valve catheter has a distal end coupled to a mop. The mop comprises a plurality of flexible extensions configured for releasable attachment to the prosthetic valve. A lead screw nut is coupled to a proximal end of the tubular delivery sleeve and a lead screw is coupled to the valve catheter. The lead screw engages the lead screw nut and rotation of the lead screw causes the delivery sleeve to retract relative to the valve catheter and the prosthetic valve for exposing the prosthetic valve. The flexible extensions of the mop allow expansion of the valve while maintaining the attachment during placement of the valve at a native valve site.
