Abstract:
1. A catheter assembly comprising: a catheter, the catheter comprising a catheter shaft, the catheter shaft defining a first guide wire lumen for passage of a first guide wire therethrough; a rotatable sheath, the rotatable sheath extending around an exterior of at least a portion of the catheter shaft and rotatable relative to the catheter shaft at a position radially outward from the catheter shaft, the rotatable sheath having a length substantially less than that of the catheter shaft; a secondary guide wire housing, the secondary guide wire housing defining a secondary guide wire lumen for passage of a secondary guide wire therethrough, at least a first distal portion of the guide wire housing in contact with at least a first proximal portion of the rotatable sheath; and a stent, the stent being expandable from a reduced stent state to an expanded stent state, and defining a flow path between a proximal end opening and a distal end opening, the stent being at least partially constructed from a plurality of interconnected stent members that define a plurality of cell openings therebetween, each of the cell openings being in fluid communication with the flow path, in the reduced stent state the stent is positioned radially outward from and extends around an exterior of at least a portion of the rotatable sheath and at least a portion of the secondary guide wire housing, a distal end portion of the secondary guide wire housing exiting the flow path of the stent through one of the plurality of cell openings.
