Patent number: 6790221Abstract: Methods for making a loaded catheter assembly for delivering a self-expanding stent where the self-expanding stent is carried in a compressed state and the compressed stent has an inside diameter smaller than the outside diameter of the catheter distal tip. The methods can utilize catheter sub-assemblies lacking already attached tips or having partially formed distal tips. A stent can be proximally and co-axially slid over the distal end of the catheter shaft and constrained by a retractable sheath disposed co-axially about the compressed stent. The catheter distal tip can be added or more fully formed after the loading of the stent. Some catheters include a preformed distal conical tip held in position by a heat-shrink film. Other catheters have an elastomeric distal tip waist for slipping over and engaging an outward projection on the catheter shaft distal region. Some catheters are adapted to engage catheter shaft distal threaded regions.Type: GrantFiled: November 7, 2001Date of Patent: September 14, 2004Assignee: SciMed Life Systems, Inc.Inventors: Lance A. Monroe, Andrew D. Bicek, Joel Phillips, Joel R. Munsinger, David Sogard

Patent number: 6579297Abstract: The inventive stent delivery system includes a catheter having a retractable outer sheath near its distal end. A shape memory contraction member having a memorized contracted shape is connected to the retractable outer sheath. A heat generating device connected to the shape memory contraction member causes the shape memory contraction member to heat up to its transition temperature and assume its contracted position, retracting the retractable outer sheath. Another embodiment utilizes 2 springs, a “normal” spring and a shape memory alloy (SMA) spring, the two springs selected and designed so that the “normal” has an expansion force which is less than SMA spring when the SMA spring is austenitic, but greater than the SMA spring when the SMA spring is martensitic.Type: GrantFiled: March 27, 2001Date of Patent: June 17, 2003Assignee: SciMed Life Systems, Inc.Inventors: Andrew D. Bicek, Lance A. Monroe, Anthony C. Vrba, Steven E. Walak

Patent number: 6458867Abstract: The present invention relates to a medical device comprising at least one tubular member having an inner surface and an outer surface. The inner surface of the tubular member is at least occasionally subjected to contact with at least one second surface. The tubular member therefore comprises a hydrophilic lubricious coating disposed on its inner surface to reduce the friction between the inner surface of the tubular member and the second surface which is caused by movement.Type: GrantFiled: September 28, 1999Date of Patent: October 1, 2002Assignee: SciMed Life Systems, Inc.Inventors: Lixiao Wang, Dachuan Yang, John Jianhua Chen, Yiqun Bruce Wang, Lance A.

Patent number: 6113608Abstract: A stent delivery system having a hydraulically actuated retractable sheath is disclosed. A pressurizing fluid is either supplied by an inflation lumen to a portion of a piston housing or is withdrawn from a portion of a piston housing, thereby actuating a piston. As the piston moves, a retractable sheath which is connected to the piston moves as well causing the sheath to retract.Type: GrantFiled: November 20, 1998Date of Patent: September 5, 2000Assignee: Scimed Life Systems, Inc.Inventors: Lance A.
