US Patent:

7284401, Oct 23, 2007
Filed:

Jan 12, 2004
Appl. No.:

10/755752
Inventors:

Karen Larson - Lino Lakes MN, US
Karl A. Jagger - Deephaven MN, US
Richard C. Gunderson - Maple Grove MN, US
Michael Gerdts - Big Lake MN, US
Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN
International Classification:

B21D 37/18
B21D 41/04
US Classification:

72 44, 72 54, 72402
Abstract:

A system for reducing the diameter of a stent comprises a stent contracting assembly and a fluid source. The assembly comprises a plurality of contracting members that define a diameter reduction chamber for receiving a stent. When the chamber is in a pre-reduction configuration the stent has a first diameter and when the chamber is in a reduced configuration the stent has a second diameter. The second diameter is less than the first diameter. The fluid source is in fluid communication with the chamber and is constructed and arranged to inject a fluid therein. The fluid forms a fluid bearing between the contracting members and the stent which prevents the contracting members from contacting the stent in the reduced diameter configuration.
