Abstract
The present invention is a device and method for securing and releasing the distal end of a thin-walled sheath to and from a distal section of a stent delivery catheter. The invention comprises a stent delivery catheter system which includes a sheath which is releasably attached to a distal section of a stent delivery catheter. When the stent delivery system has been advanced into the body so that the stent (which is situated coaxially within the sheath) is placed at the site of an arterial stenosis where it is to be deployed, the sheath is released from the stent delivery catheter and then the sheath is pulled back in a proximal direction thereby uncovering the stent. Self-deploying stents will automatically deploy when the sheath is pulled back. Balloon expandable stents can be deployed by balloon inflation after the sheath has been pulled back. One embodiment of the distally attachable and releasable sheath utilizes a guide wire that passes through the stent delivery catheter first to hold and then to release the distal end of the sheath from a distal section of the stent delivery catheter.
