摘要： The invention provides a rotational atherectomy system, device and method comprising a flexible, elongated, rotatable drive shaft with an abrasive section within a pre-curved section of the drive shaft. The device may further comprise a concentric or eccentric enlarged diameter section that is at least partially covered with abrasive material to comprise the abrasive section. The abrasive section may further comprise an abrasive crown or burr mounted to the drive shaft. The pre-curved drive shaft allows smaller diameter and/or massive abrasive regions to be used while sweeping larger diameters during high-speed rotation. The pre-curved region is substantially straightened for insertion into vasculature and placement adjacent stenosis by insertion of the guide wire. Removal of guide wire proximally from the pre-curved region allows the drive shaft to return to its pre-curved form for ablation. Reinsertion of the guide wire beyond the pre-curved region straightens the drive shaft for ease of removal.

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.
