Abstract: An endoprosthesis delivery catheter assembly comprises a placement catheter having first and second catheter shafts. A handle includes a body and an actuator mounted to the body for movement relative to the body. The proximal portions of the first and second catheter shafts are mounted to the handle. At least one of the proximal portions of the first and second catheter shafts are drivenly coupled to the actuator so that movement of the actuator causes rotary and/or axial movement of the first and second catheter shafts relative to one another. The actuator may be mounted to the body for both rotary and axial movement relative to the body so that rotary and axial movement of the actuator causes corresponding relative rotary and axial movement of the first and second catheter shafts. The number of turns and/or the length of the coiled endoprosthesis may be selectively changed using a single actuator and then released from the catheter.
