US Patent:

6527739, Mar 4, 2003

Filed:

Dec 29, 2000

Appl. No.:

09/752203

Inventors:

Steve Bigus - San Jose CA
Carl Simpson - Los Altos CA
Kevin M. Mauch - Windsor CA

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61M 2900

US Classification:

60410101

Abstract:

A catheter balloon arrangement for application in tortuous blood vessels. First and second spiraled balloons are coupled to a catheter body portion. The spiraled balloons can have first and second apexes with a pitch length there between configured to encourage tortuous compatibility between the catheter balloon arrangement and a body lumen. A method of treatment with an embodiment of a catheter balloon arrangement is also provided.

International Classification:

A61B 1736

US Classification:

606 7

Abstract:

An intravascular device for forming a channel within a patient's ventricular wall which engages the tissue of the ventricular wall to prevent undesirable movement of the channel forming device while forming the channel.

International Classification:

A61B 1736

US Classification:

606 7

Abstract:

The method for intra-operative myocardial revascularization of a human heart includes a inserting a portion of an elongated flexible lasing apparatus into the chest cavity of a patient, and lasing channels from the epicardium through the myocardium of the heart, without mechanical tearing of the heart tissue. The apparatus is guided to an area exterior to a ventricle of the patient's heart, and the distal end of the optical fiber apparatus is directed to an area of interest where the exterior wall of the heart is irradiated with laser energy to form a channel through the myocardium.
