Abstract
Official abstract text for this publication.
A delivery system and method for delivering a prosthetic heart valve to the aortic valve annulus. The system includes a delivery catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve to the aortic annulus in an antegrade fashion through an introducer passing into the left ventricle through its apex. The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall while preserving good operating field stability. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation within the aortic annulus. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of deploying and implanting a prosthetic heart valve into a beating heart, comprising: while the heart is beating, forming an incision and passing an introducer having a stiff proximal section into the left side of the heart; advancing a balloon catheter having a heart valve mounted on a distal balloon into and through the introducer such that the heart valve is positioned within the aortic annulus, the balloon catheter having a proximal control h…
