Filed:

Jul 23, 1999

Appl. No.:

09/360257

Inventors:

Chien-Suu Kuo - Lexington KY
John C. Gurley - Lexington KY

Assignee:

University of Kentucky Research Foundation - Lexington KY

International Classification:

A61B 1818

US Classification:

606 41, 606 42, 607101, 607113

Abstract:

An electrode catheter is provided having a predetermined flexibility throughout the entire length or at least at the contact portion, such as the electrode region, to allow for the molding of the contact portion such that it conforms to the shape of the heart at a preselected desired target area, such as the isthmus between the inlet of inferior vena cava and posterior tricuspid annulus. The catheter also includes a guiding sheath that is preferably semirigid and may be pre-shaped with at least one bend or angulation to assist in molding to ensure that the electrode region overlies the desired target treatment area. A remotely controlled anchoring device is provided at the distal end of the catheter for anchoring it in position to facilitate the molding operation and placement over the target treatment area. A method of cardiac ablation using the catheter of the present invention is also disclosed.

International Classification:

A61B 8/06

US Classification:

600454

Abstract:

A diagnostic system for detecting a right-to-left cardiopulmonary shunt in a patient. The system includes at least one Doppler ultrasound transducer, a transducer housing, a transducer housing placement device to affix the Doppler ultrasound transducer housing over a peripheral blood vessel, and a control system configured to receive and process the echoes and transform the echoes into data indicative of the presence or absence of a bubbles within the peripheral blood vessel, thereby determining whether or not the patient has a right-to-left cardiopulmonary shunt. A method of detecting a right-to-left cardiopulmonary shunt in a patient is also provided.
