US Patent:

6689110, Feb 10, 2004

Filed:

Nov 25, 2002

Appl. No.:

10/303945

Inventors:

Stephen Brushey - Pittsburgh PA

Assignee:

Micor, Inc. - Allison Park PA

International Classification:

A61M 500

US Classification:

604264, 60416409, 600500

Abstract:

The present invention provides a catheter which combines the benefits of improved drug dispersion, increased accuracy of placement and kink and collapse resistance. The catheter comprises a flexible cylindrical tube having a proximal portion open at one end and a distal portion, the portions in fluid communication, the distal portion comprising a closed, rounded tip and a diffusion area having at least one opening therein which permits fluid flow, the proximal portion including a proximal tip, and at least one reinforcement member attached at the distal tip and at the proximal tip of the flexible cylindrical tube, with the remainder of the at least one reinforcement member movable within the flexible cylindrical tube. The catheters of the present invention can find use in a variety of local, regional and peripheral pain management applications.

Appl. No.:

10/797958

Inventors:

Stephen Brushey - Pittsburgh PA, US

Assignee:

Micor, Inc. - Bethlehem PA

International Classification:

A61B 17/20

US Classification:

604 21, 604 19, 604 20

Abstract:

A catheter is comprised of a flexible cylindrical tube defining a proximal portion and a distal portion terminating in a distal tip. The tube has a plurality of openings formed therethrough to form a diffusion area. The catheter includes a conductive end cap enclosing a distal tip. A flexible conductive member is attached to the conductive end cap and extends to the proximal portion where it is attached to the inside diameter of the flexible tube. The member is movable within the tube. Because of the rules governing abstracts, this abstract should not be relied upon in construing the claims.
