    摘要: A system and method for application of therapeutic and protective coatings to multiple tubular medical devices in a high volume production process. One or more tubular medical devices, such as stents, are placed on a coating-absorbent core, and coating is applied to the device(s), for example, as when the device-carrying core is passed through an extrusion coating machine to apply the coating in a uniform manner. Once coated, the medical device(s) may be quickly and efficiently removed from the core by causing the core diameter to decrease, such as by applying elongating tension to the core to cause the core diameter to radially contract, thereby allowing the coated device(s) to be simultaneously freed from the core. Improved coating uniformity, increased coated device removal ease and minimized bridging of openings in the tubular medical device may be obtained with a core that absorbs excess coating.

    摘要: A stent delivery system which includes a stent delivery catheter, the stent delivery catheter having a stent mounting region, the stent mounting region having an inflatable portion. A stent is disposed about the stent mounting region, the stent having an unexpanded position and an expanded position. At least one stent retaining sleeve is also included having first and second ends, the first end being attached to the stent delivery catheter, the at least one stent retaining sleeve disposed about at least a portion of the stent in the unexpanded position, the stent retaining sleeve being constructed and arranged to retract toward the attached first end when the stent is expanded.

    摘要: A balloon catheter comprises a balloon, an inner shaft, an outer shaft and a transition shaft. The transition shaft has a proximal portion and a distal portion joined by a tapered portion. The proximal portion has a diameter greater than the distal portion. The proximal portion has a first end portion engaged to at least a portion of the outer shaft at a first engagement site. At least a portion of the proximal waist is engaged to the proximal portion of the transition shaft at a second engagement site. At least a portion of the end region of the inner shaft is engaged to the distal portion of the transition shaft at a third engagement site. The distal portion extends through the balloon wherein at least a portion of the distal waist of the balloon is engaged to the distal portion of the transition shaft at a forth engagement site.
