Filed:

Jan 12, 2004

Appl. No.:

10/755752

Inventors:

Karen Larson - Lino Lakes MN, US
Karl A. Jagger - Deephaven MN, US

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.

International Classification:

A61F 2/06

US Classification:

623 111

Abstract:

Implantable medical endoprosthesis delivery systems and methods for making and using the same. An example implantable medical endoprosthesis delivery system may include an inner member having a first lumen disposed therein. An outer member may at least partially surround the inner member so that a second lumen is disposed between the inner and outer members. The second lumen may be configured so that an implantable medical endoprosthesis can be disposed therein. The delivery system may also include a hub including a fluid introduction port, a first fluid flow path in fluid communication with the fluid introduction port, and a second fluid flow path in fluid communication with the fluid introduction port.

International Classification:

A61F 2/06

US Classification:

623 111

Abstract:

Endoprothesis delivery systems and methods for making an using the same. An example medical endoprosthesis delivery system may include an inner member. An outer member may at least partially surround the inner member. The inner member and the outer member may be configured so that an implantable medical endoprosthesis can be disposed therebetween. A coupling device may be coupled to a portion of the outer member so that, when there is substantially no slack in the coupling device, as the coupling device moves in a proximal direction the portion of the outer member moves in the proximal direction. An adjustable stop may be coupled to the coupling device so that, when there is slack in the coupling device, as the adjustable stop is moved in the proximal direction, the amount of slack in the coupling device can be reduced.

International Classification:

A61M 29/00

US Classification:

604103, 604529

Abstract:

A catheter tip assembly comprises a catheter tip having a fill port and an inner lumen having at least one cavity. The cavity is in communication with the fill port. The cavity is constructed and arranged to receive a radiopaque material through the fill port. The radiopaque material adhesively engages the catheter tip to a catheter.

International Classification:

A61F 2/06

US Classification:

623 112, 606108

Abstract:

Medical systems and related methods are described. In some embodiments, the medical systems include an outer member defining a slot. In certain embodiments, the outer member at least partially surrounds an inner member, and the outer and inner members are configured so that an implantable medical endoprosthesis can be disposed between the outer and inner members.
