1. A catheter assembly comprising:
- a catheter, the catheter comprising a catheter shaft and a balloon disposed about a distal region of the catheter shaft, the balloon being expandable from and between a reduced diameter configuration and an expanded diameter configuration;
a rotatable sheath, the rotatable sheath being rotatably disposed about at least a portion of the balloon and rotatable relative to the balloon, the rotatable sheath having a length less than that of the balloon, the rotatable sheath comprising a first end region, a second end region and a stent receiving region therebetween;
a stent, the stent having a proximal opening and a distal opening, the stent being expandable from a reduced stent state to an expanded stent state, in the reduced stent state the stent being disposed about the stent receiving region of the rotatable sheath, the first end of the rotatable sheath extending beyond a proximal end region of the stent and the second end region of the rotatable sheath extending beyond a distal end region of the stent, the stent at least partially constructed from a plurality of interconnected members, the interconnected members defining a plurality of cell openings, the cell openings positioned between the proximal opening and distal opening; and
a guidewire housing, the guidewire housing defining a guidewire lumen for passage of a guidewire therethrough, at least a portion of the guidewire housing being fixed attached to at least a proximal portion of the rotatable sheath, at least a portion of the guidewire housing extending distally through one of the cell openings.

Abstract
A catheter assembly comprises a catheter, a rotatable sheath, a guidewire housing and a stent. The rotatable sheath is disposed about at least a portion of the catheter shaft and is rotatable thereabout. The stent is disposed about a stent receiving region of the rotatable sheath and at least a portion of the guidewire housing. The first end of the rotatable sheath extends beyond a proximal end region of the stent and the second end region of the rotatable sheath extends beyond a distal end region of the stent.

39. A catheter assembly comprising:
-
a catheter shaft having a proximal region and a distal region; a balloon disposed about a portion of the distal region of the catheter shaft, the balloon being expandable between a reduced diameter configuration and an expanded diameter configuration; a rotatable sheath, the rotatable sheath being rotatably disposed about at least a portion of the balloon and rotatable relative to the balloon, the rotatable sheath comprising a first end region, a second end region and a stent receiving region therebetween, the rotatable sheath having limited longitudinal movement relative to the balloon; a stent, the stent having a proximal opening and a distal opening, the stent being expandable from a reduced stent state to an expanded stent state, in the reduced stent state the stent being disposed about the stent receiving region of the rotatable sheath, the stent at least partially constructed from a plurality of interconnected members, the interconnected members defining a plurality of cell openings, the cell openings positioned between the proximal opening and distal opening; a guidewire housing, the guidewire housing defining a guidewire lumen for passage of a guidewire therethrough, at least a portion of the guidewire housing being fixed attached to at least an outer surface of the rotatable sheath; and further comprising a collar rotatably disposed about a portion of the catheter shaft, wherein the collar is directly attached to the guide wire housing to limit longitudinal movement of the rotatable sheath relative to the balloon. - View Dependent Claims (40)
