1. A catheter assembly comprising:
- a catheter, the catheter comprising a catheter shaft;
a first rotatable sheath, the first rotatable sheath including a radial outer surface and a radial inner surface, the first rotatable sheath being disposed about and rotatable relative to a portion of the catheter shaft, the first rotatable sheath having a length substantially less than that of the catheter shaft, the first rotatable sheath being expandable from a reduced sheath state to an expanded sheath state, in the reduced sheath state the first sheath being rotatable about the portion of the catheter shaft;
a first guidewire housing, the first guidewire housing defining a first guidewire lumen for passage of a first guidewire therethrough, at least a portion of the first guidewire housing being engaged to the radial outer surface of the first rotatable sheath;
a first stent, the first stent being expandable from a reduced stent state to an expanded stent state, in the reduced stent state the stent being disposed about at least a portion of the first rotatable sheath and at least a portion of the first guidewire housing; and
a second stent, the second stent being expandable from a reduced stent state to an expanded stent state, in the reduced stent state the second stent being disposed about the catheter shaft adjacent to the first stent.
