Filed:

May 20, 2002

Appl. No.:

10/151354

Inventors:

Huybregts M.A.J.M. - Ouderkerk a/d Amstel, NL
Robert Todd - Salt Lake City UT, US
Alison Curtis - Riverton UT, US

International Classification:

A61F007/12

US Classification:

604/113000, 604/096010, 604/500000, 428/035200, 264/454000

Abstract:

A novel improved enhanced cardiac surgical method yields unexpected results by having an enhanced intraluminally emplaced cooling system. In preferred device embodiments improvements include a first means for draining venous blood from at least one of the right atrium, superior vena cava and inferior vena cava and an improved means for cooling involved luminal surfaces. Tissue insult and injury is substantially mitigated by engagement of the cooling means with select aspects of involved atrial tissue to facilitate transfer of heat. Methods for making embodiments of the invention are provided. A method for the treatment of cardiac disease using the improved enhanced cardiac surgical cooling system, and an article of manufacture, comprising packaging material and the device are also taught. Likewise, the alternate cooling mechanisms disclosed have applicability both on- and off-pump in a variety of procedures ranging from traditional open cardiac surgical repair and by-pass to endovascular procedures using percutaneous access and minimally invasive therapies.

Abstract:

A novel improved enhanced cardiac surgical method yields unexpected results by having an enhanced intraluminally emplaced cooling system. In preferred device embodiments improvements include a first means for draining venous blood from at least one of the right atrium, superior vena cava and inferior vena cava and an improved means for cooling involved luminal surfaces. Tissue insult and injury is substantially mitigated by engagement of the cooling means with select aspects of involved atrial tissue to augment transfer of heat. In one embodiment of the invention, the right atrium is cooled while the patient's body is maintained at a normothermic temperature during surgery. The alternate cooling mechanisms disclosed have applicability both on- and off-pump in a variety of procedures ranging from traditional open cardiac surgical repair and by-pass to endovascular procedures using percutaneous access and minimally invasive therapies.
