摘要：
A steerable delivery catheter includes an outer sheath with a housing disposed at a distal end thereof to define a chamber for a medical device, the chamber having an open distal end and a proximal inner shelf. An inner shaft is slidably disposed within the sheath and has an abutment attached to the distal end of the shaft, the abutment being slidably contained within the chamber. During navigation of the catheter, when the inner shaft is tensioned the abutment engages the shelf to apply a compressive force to the sheath to selectively deflect a distal region of the catheter. When the catheter has been navigated to the deployment site the sheath is withdrawn while the abutment maintains the medical device in place as it is deployed. A delivery method also is disclosed.
