Patent number: 6506201Abstract: An assembly for delivery and deployment of an inflation expandable stent within a vessel is comprised of a catheter, an inflation expandable stent, an expandable balloon, and a securement device such as a corrugated tube component or an expandable tube component. The tube component is mounted on the inner shaft beneath the balloon and provides increased securement to the stent in a reduced delivery diameter to maintain the stent on the catheter during delivery to the deployment site. The tube component is adhered to the inner shaft and has a plurality of ribs or is fluid expandable to no more than the delivery diameter, and may be comprised of more than one separately inflatable pouch expandable to provide the stent with a substrate seat with increased friction and to decrease the slack in stent recoil crimping. The assembly is used in a method for delivering and deploying a stent, and also adds safety when loading/crimping the stent onto a balloon.Type: GrantFiled: December 12, 2000Date of Patent: January 14, 2003Assignee: Scimed Life Systems, Inc.Inventors: Fernando Di Caprio, Stanley A. Nordin, Louis G. Ellis, Andrew J. Dusbabek

Patent number: 6395008Abstract: An assembly and a method to deliver and deploy and inflation expandable stent is described. The assembly has a catheter with an annular collar is coaxially located on the catheter distal end. An expandable balloon, in a contracted state, is coaxially mounted over the collar at the catheter distal end. A stent, in a reduced configuration, is coaxially mounted on the balloon and conformed to the catheter and collar. At least one cup is coaxially mounted on the catheter distal end. The cup and collar are cooperate to retain the end portion of the reduced stent on the catheter. The balloon is inflated to expand the stent and release the stent from the cup or cups. The cup can be axially spaced from the collar. The cup can be fixed to the catheter or can be freely sliding on the catheter. The cup can overlie at least a portion of the collar. The collar can be shaped as a single member with the catheter.Type: GrantFiled: August 23, 1996Date of Patent: May 28, 2002Assignee: SciMed Life Systems, Inc.Inventors: Louis G. Ellis, Andrew J.

Patent number: 6387117Abstract: An apparatus for reducing a medical device such as a stent in size is formed of cooperating crimping dies which are joined via a crimping die moving device. As the cooperating dies are moved together, an inward force is applied to the medical device to reduce the medical device in size.Type: GrantFiled: September 22, 1999Date of Patent: May 14, 2002Assignee: SciMed Life Systems, Inc.Inventors: John E. Arnold, Jr., Terry V. Brown, Andrew J. Dusbabek, Christopher J. Elliott, Louis G. Ellis, Christopher R. Larson, Gary J. Leanna
