Abstract:
1. Apparatus for delivering a prosthetic heart valve into a patient, comprising: a longitudinal outer shaft extending from a proximal portion of the apparatus to a distal portion of the apparatus; a longitudinal inner shaft disposed inside the outer shaft, the inner shaft being longitudinally movable relative to the outer shaft; a tip structure mounted on a distal portion of the inner shaft for substantially closing a distal end of the outer shaft when the inner shaft is pulled proximally back relative to the outer shaft; a prosthetic heart valve disposed around the inner shaft proximal of the tip structure and inside a distal portion of the outer shaft, the prosthetic valve being releasable from the apparatus when the tip structure is moved distally away from the distal end of the outer shaft and the prosthetic valve is shifted distally beyond the distal end of the outer shaft; a collar structure disposed around the inner shaft and spaced proximally from the tip structure, the prosthetic valve being positioned between the collar structure and the tip structure; and a plurality of strands releasably securing the prosthetic valve to the collar structure.
