Abstract
A delivery apparatus includes a steerable guide sheath. The steerable guide sheath has a steerable portion, a pull ring located in the distal portion, and a pull wire coupled at one end to the pull ring and coupled at the opposite end to a control handle. The pull wire extends longitudinally through a pull-wire conduit. The steerable guide sheath further includes a compression-resistance portion made of metal and located in the distal portion.
Claims20
A steerable guide sheath, comprising:
- a steerable portion configured to flex and unflex to adjust the curvature of a distal portion of the guide sheath;
- a pull ring located in the distal portion;
- a first pull wire coupled at one end to the pull ring and coupled at the opposite end to a control handle, wherein the first pull wire extends longitudinally through a first pull-wire conduit;
- and
- a compression-resistance portion made of metal and located in the distal portion.
A delivery apparatus for a prosthetic device, comprising:
- a steerable guide sheath;
- a steerable catheter disposed within the guide sheath;
- an implant catheter coaxially disposed within the steerable catheter, wherein the prosthetic device is mounted on a distal end of the implant catheter;
- wherein the steerable guide sheath comprises:
- a steerable portion configured to flex and unflex to adjust the curvature of a distal portion of the guide sheath;
- a pull ring located in the distal portion;
- a first pull wire coupled at one end to the pull ring and coupled at the opposite end to a control handle, wherein the first pull wire extends longitudinally through a first pull-wire conduit;
- and
- a compression-resistance portion made of metal and located in the distal portion.
A steerable guide sheath, comprising:
- a steerable portion configured to flex and unflex to adjust the curvature of a distal portion of the guide sheath;
- a pull ring located in the distal portion;
- a first pull wire coupled at one end to the pull ring and coupled at the opposite end to an adjustment knob located on a control handle, wherein the first pull wire extends longitudinally through a first pull-wire conduit;
- a second pull wire coupled at one end to the pull ring and coupled at the opposite end to the adjustment knob, wherein the second pull wire extends longitudinally through a second pull-wire conduit;
- and
- a compression-resistance portion made of metal and located in the distal portion opposite the first and second pull wire conduits,
- wherein a plane bisecting the distal portion and passing between the first and second pull-wire conduit bisects the compression-resistance portion.
