Abstract: A large lumen guide catheter has an elongate tubular body, which has an outer surface, an inner surface, and a braided wire layer between the inner surface and the outer surface, wherein the wires winding a first helical direction are thicker and wider than the wire winding in a second helical direction opposite the first helical direction.

Abstract: Various embodiments for a stent delivery device or catheter system that includes a stent disposed between an inner shaft and an outer sheath. A housing is coupled to the inner shaft and outer sheath with a rotary reel disposed in the housing and configured for rotation with respect to the housing. A hypotube is disposed in the housing and fixed thereto with the inner shaft extending into the opening of the hypotube and the outer sheath enshrouding a portion of the hypotube. Rotation of the rotary reel in a first direction pulls the outer sheath over the hypotube along the generally circular path to retract the outer sheath from the stent. In some embodiments, a rapid deployment mechanism allows for retracdtion of the outer sheat at an increased rate.

Abstract: A hemostasis pressure device is disclosed. In one embodiment, the hemostasis pressure device includes a reusable component and a disposable cuff. The disposable cuff includes a pre-inflated pad configured to be placed at an access site on a patient. A knob secured to the reusable component is configured to control the pressure applied to the pre-inflated pad, providing incremental, fine-tuned control of pressure applied to the access site to achieve patent hemostasis.
