6458070, Oct 1, 2002

Filed:

Dec 21, 1999

Appl. No.:

09/469103

Inventors:

Ron Waksman - Atlanta GA
Thomas D. Weldon - Gainesville GA
Richard A. Hillstead - Duluth GA

Raphael F. Meloul - Atlanta GA

Assignee:

Novoste Corporation - Norcross GA

International Classification:

A61N 500

US Classification:

600 3

Abstract:

Apparatus and method are described for delivery of a treating element, such as a radiation source, through a catheter to a desired site in the vascular system of a patient, such as a coronary artery, for inhibiting the formation of scar tissue such as may occur in restenosis following balloon angioplasty. The apparatus includes an elongated flexible catheter tube having proximal and distal end portions, with a lumen extending therebetween, and a diameter sufficiently small for insertion in to a patients vascular system. One or more treating elements, such as a capsule or pellet containing radioactive material, is positionable within the lumen and movable between the proximal and distal end portions under the force of liquid flowing through the lumen. A method for using such apparatus, including a method for using such apparatus simultaneously with a balloon angioplasty procedure, is disclosed.

Assignee:

Novoste Corporation - Norcross GA

International Classification:

A61M 3100

US Classification:

604 9301, 604 48, 604 35

Abstract:

Methods and apparatus are disclosed for treating body tissue whereby a section of tissue is drawn into contact with the open distal end of the first passageway of the apparatus. A tissue treatment fluid is introduced into the second passageway for treating the desired section of tissue retained within the first passageway. Methods and apparatus are also disclosed for positioning a medical device at a desired location within the heart. A portion of the apparatus is retained at a desired location of the heart and a medical device is extended through a passageway of the apparatus for contacting the heart at the desired location.
