  • STEERABLE CATHETER WITH PULL WIRE
    Publication number: 20160158497
    Abstract: In one representative embodiment, a steerable catheter device comprises a shaft comprising a proximal portion, a distal portion, and a pull-wire lumen that extends at least partially through the proximal and distal portions. A pull wire extends through the pull-wire lumen and has a proximal end portion and a distal end portion, wherein the distal end portion of pull wire is fixed to the distal end portion of the shaft. An adjustment mechanism is operatively connected to the proximal end portion of the pull wire and configured to increase and decrease tension in the pull wire to adjust the curvature of the distal portion of the shaft. An axially non-compressible pull-wire sleeve extends co-axially through the pull-wire lumen and over the pull wire.

  • LOW PROFILE DELIVERY SYSTEM FOR TRANSCATHETER HEART VALVE
    Publication number: 20150272733
    Abstract: A heart valve delivery apparatus includes a valve carrying member. A prosthetic valve is crimped onto the valve carrying member at a location that is distal or proximal to the balloon member, thereby providing a smaller profile delivery apparatus.

  • Integrated heart valve delivery system
    Patent number: 8568472
    Abstract: Embodiments of the present disclosure provide a delivery apparatus for delivering a prosthetic heart valve to a native valve site via the human vasculature. The delivery apparatus is particularly well-suited for advancing a prosthetic valve through the aorta (i.e., in a retrograde approach) for replacing a stenotic aortic valve.
