    Abstract: A rapid exchange sheath comprising an elongate tubular member, a guidewire, and support wire having an expandable filter at a distal end. The guidewire passes through a first opening at a distal end of the tubular member and a second opening a short distance proximal from the distal end. The support wire is received in a lumen of the tubular member, or, in certain embodiments, extends proximally through a third opening a short distance proximal from the distal end. Methods of using the sheaths for deploying and/or exchanging medical device(s) in a patient's vessel are also disclosed.

    Abstract: An apparatus for positioning an introducer sheath includes a sheath having a distal end including first and second ports, the second port being located distally from the first port. An obturator is slidable within the sheath that includes a distal region that sealingly engages an interior surface of the sheath. The obturator includes first and second openings in the distal region that are alignable with the first and second ports in the sheath. A housing is slidable on the exterior of the sheath that releasably holds a closure element. The sheath may be inserted into an incision communicating with a blood vessel, the first and second ports providing backbleed indication of the depth of the insertion of the sheath into the vessel. The housing is actuated to deploy the closure element to engage and close the incision.

    Abstract: The system (2) includes a catheter drive unit (22) and a catheter (24) extending therefrom movably mounted to a catheter drive sled (26). The catheter drive unit rotates and translates the catheter core (34) within the catheter sheath (36). The sled has a serrated, conical drive unit interface (82), with a bag-piercing tip (86) mateable with a translator drive ouput (92) so that a sterile drape (112) enclosing the catheter drive unit is automatically pierced when the catheter drive unit is mounted to the sled. A control unit (6) is spaced apart from the catheter drive unit and provides power and commands to the catheter drive unit and receives information and data from the catheter drive unit. The rotator and translator drive motors (54, 90) are operated from both the control unit and the catheter drive unit. Both the control unit and catheter drive unit have translation displacement displays (10, 30).
