Abstract
A holder for a hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a non-expandable, non-compressible prosthetic valve and a self-expandable anchoring stent, thereby enabling attachment to the annulus without sutures. A first suture connects the holder to the valve and constricts an inflow end of the anchoring stent. A second suture connects the holder to the valve and extends down three holder legs to loop through fabric on the valve. Both sutures may loop over a single cutting well on the holder so that severing the first and second sutures at the single cutting well simultaneously releases the tension in the first suture, permitting the inflow end of the anchoring stent to expand, and disconnects the valve holder from the prosthetic heart valve.
Core Innovation
The invention is a system for delivering a prosthetic heart valve to a native valve annulus. The valve includes an annular support structure and a self-expandable anchoring stent that together define a flow orifice, with valve leaflets attached to the support structure. A valve holder adapted to mate with a delivery handle attaches to the valve at multiple locations by a connecting suture.
The connecting suture is routed over a single cutting well and extends around the anchoring stent in tension, constricting its second end to a contracted state for delivery. Severing the suture at the cutting well detaches the holder, and the described arrangement permits release of the stent. The problem being solved in the background section is not explicitly described in the provided patent content.
Claims Coverage
The provided relevant claims identify one independent claim, claim 1, covering three principal inventive features of the delivery system.
Prosthetic heart valve with a self-expandable anchoring stent
The prosthetic heart valve includes an annular support structure and a self-expandable anchoring stent together defining a flow orifice, with valve leaflets attached to the support structure and mounted to alternately open and close across the flow orifice.
Valve holder adapted to mate with a delivery handle
The valve holder has a structure adapted to mate with a delivery handle.
Connecting suture routed over a single cutting well
A connecting suture attaches the valve holder to the prosthetic heart valve at multiple locations and is routed over a single cutting well, such that severing it at the cutting well detaches the holder. The suture extends around the anchoring stent in tension and constricts its second end to a contracted state for delivery to the native valve annulus.
Claim 1 covers the valve and self-expandable anchoring stent, a holder configured for a delivery handle, and a connecting suture that both secures the holder and constricts the stent for delivery, with severing at the single cutting well detaching the holder.
