摘要： A stent delivery system which includes a self dividing and retracting stent retaining sleeve having a ribbed configuration. The ribbed configuration providing the sleeve with reduced columnar strength and an improved radial strength characteristics. The present stent delivery system further providing for a perforated portion on the sleeve which will rupture at a predetermined pressure thereby dividing the sleeve into a proximal portion and a distal portion. The ribbed sleeve portions providing a recoil action in opposite longitudinal directions to the individual sleeve portions which assists in actively retracting the sleeve portions off of the stent being expanded.

摘要： An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel. The freely-spinning motor allows the large angular momentum of the system to dissipate rapidly and safely, without excessive torque to the drive shaft.
