Filed:

Mar 13, 1998

Appl. No.:

09/039110

Inventors:

Celso J. Bagaoisan - Union City CA
Jeffrey C. Bleam - Boulder Creek CA
Isaac J. Kim - San Jose CA
Jeffrey F. Field - Northridge CA

Assignee:

Medtronic PercuSurge, Inc. - Sunnyvale CA

International Classification:

A61M 2900

US Classification:

604 9902, 604 9701, 604 9601, 60416703, 604537, 606194

Abstract:

Disclosed herein is a low profile catheter valve comprising a movable sealer portion positioned within the inflation lumen of a catheter. The sealer portion forms a fluid tight seal with the inflation lumen by firmly contacting the entire circumference of a section of the inflation lumen. The sealer portion may be positioned proximally of a side-access inflation port on the catheter, to establish an unrestricted fluid pathway between the inflation port and an inflatable balloon on the distal end of the catheter. As desired, the clinician may move the sealer portion to a position distal of the inflation port, thereby preventing any fluid from being introduced into or withdrawn from the balloon via the inflation port.

Appl. No.:

8/744632

Inventors:

Jeffrey F. Field - Northridge CA

Assignee:

Percusurge, Inc. - Sunnyvale CA

International Classification:

A61M 2900

US Classification:

606198

Abstract:

A stent positioning apparatus and method are provided for the attachment of a stent to a balloon to be used in the treatment of stenosis, such as coronary angioplasty. In one preferred embodiment, a first generally cylindrical member has a radially deformable wall defining a channel within which the stent and balloon assembly are inserted. A second generally cylindrical member has an opening sufficient to receive the first member with the assembly therein. The second member is then slid longitudinally over the deformable wall of the first member causing nonuniform depressions to be formed in the inner diameter of the stent, thus crimping the stent onto the balloon. Thus, the stent is attached to the balloon without damage and without risk of the stent falling off the balloon prematurely.
