Transapical delivery system for heart valves

摘要: A delivery system and method for delivering a prosthetic heart valve to the aortic annulus. The includes catheter having steering mechanism thereon balloon-expandable annulus in an antegrade fashion through introducer passing into left ventricle its apex. may have more floppy distal section than proximal reduce trauma wall while preserving good operating field stability. deflecting segment just balloon facilitate positioning of proper orientation within trigger handle be coupled deflection wire that actuates segment, slider controls retraction pusher. installed over existing calcified leaflets, pre-dilation valvuloplasty procedure also utilized.
