Publication number: 20040098082Abstract: An angioplasty and stent delivery system to facilitate introduction and placement of a stent, including a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state: a stent positioned around the distal portion of the catheter having a contracted condition and being expandable to an expanded condition, and being sized in the contracted condition to closely surround the catheter in the contracted state, the expandable distal portion of the catheter including a balloon within which or over which there is included on a catheter shaft at least one axially movable or enlargeable body of a diameter larger than the catheter shaft to which the stent and balloon are fitted, as by crimping, for holding the stent in place until it is released therefrom by expansion of the balloon.Type: ApplicationFiled: August 26, 2003Publication date: May 20, 2004Applicant: SCIMED LIFE SYSTEMS, INC.Inventors: Charles L. Euteneuer, Christopher R. Larson, Steven P. Mertens, Richard C. Mattison, David J. Blaeser, Louis G. Ellis, Andrew J. Dusbabek, Terry V. Brown

Publication number: 20030056360Abstract: A stent crimper comprising a plurality of crimping members extending between a first support and a second support. The first and optionally the second supports has an opening therethrough sized to allow a stent therethrough. The first and second supports extend from a base. The crimping members are disposed about the circumference of a circle everywhere along the length of the members. Finally, the flexible members extend through a bore in a die. The die is movable in an axial direction along the flexible members.Type: ApplicationFiled: September 22, 1999Publication date: March 27, 2003Inventors: TERRY V. BROWN, ANDREW J. DUSBABEK, LOUIS G.
