Appl. No.:

10/755752

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.

US Classification:

623 111

Abstract:

A catheter assembly comprises a catheter, a rotatable sheath, a guidewire housing and a stent. The rotatable sheath is disposed about at least a portion of the catheter shaft and is rotatable thereabout. The stent is disposed about a stent receiving region of the rotatable sheath and at least a portion of the guidewire housing. The first end of the rotatable sheath extends beyond a proximal end region of the stent and the second end region of the rotatable sheath extends beyond a distal end region of the stent.

Abstract:

A balloon folding system specifically configured to reduce a side branch balloon of a bifurcated balloon catheter assembly includes a die that defines at least one chamber for receipt of the sidebranch balloon, and at least one pin sized to fit into the chamber and reduce the balloon to a substantially flattened state. The system also may include a housing for the reduction and folding of a primary branch balloon. The system is configurable to fold and reduce both branches simultaneously or separately.
