Publication number: 20020151870Abstract: A method and device for occluding a patient's ascending aorta, maintaining circulation of oxygenated blood in the patient and delivering cardioplegic fluid to arrest the patient's heart. An aortic occlusion catheter has an occluding member for occluding the ascending aorta. The aortic occlusion catheter passes through a cannula. Delivery of oxygenated blood is accomplished through either the cannula of the aortic occlusion catheter. In another aspect of the invention, an arterial cannula having a curved or angled distal portion. An introducer straightens the distal portion for introduction into the patient. In still another aspect of the invention, an open-mesh stabilizer is used to stabilize a discoid occluding member.Type: ApplicationFiled: June 5, 2002Publication date: October 17, 2002Inventors: Kevin V. Grimes, Jan Komtebedde, Daniel C. Rosenman, Hanson S. Gifford, Michi E. Garrison, Wesley D. Sterman, David M. Taylor, A. Adam Sharkawy, Pinaki Ray

Publication number: 20020082584Abstract: A system and method for delivering a drug to a target site within a patient's body. The system and method include a steerable guide catheter and a drug delivery catheter. The steerable guide catheter has a first extension tube and a second extension tube that are joined together and form a shoulder. The delivery catheter has a distal docking segment and a proximal docking segment. The guide catheter is inserted into the patient's body, then the delivery catheter is inserted into the guide catheter. The distal docking segment engages the first extension tube, the proximal docking segment engages the second extension tube, and the shoulder limits the distance the delivery catheter can be inserted into the guide catheter. Also, once the delivery catheter is inserted it can be rotated to attach the helical tip to the target site. The guide catheter also includes a steering mechanism as well as a friction mechanism which controls the tension on the steering mechanism.Type: ApplicationFiled: December 22, 2000Publication date: June 27, 2002Inventors: Daniel C.

Patent number: 6152141Abstract: A method for delivering a therapeutic agent directly to the heart employing minimally invasive techniques and concepts. In particular, the delivery of vascular endothelial growth factors (VEGF) is performed endovascularly or endoscopically to a region of a patient's heart treated with transmyocardial revascularization (TMR). A system is provided for inducing cardioplegic arrest. An aortic occlusion device has an inflatable balloon which occludes the ascending aorta when inflated. Cardioplegic fluid may be infused through a lumen of the aortic occlusion device to stop the heart while the patient's circulatory system is supported on cardiopulmonary bypass. A side-firing fiberoptic laser is introduced through the aortic occlusion device in the endovascular technique to perform TMR. Subsequently, a therapeutic agent delivery catheter is directed into one of the coronary arteries to deliver and dissipate the VEGF into the surrounding vascular plexus to promote angiogenesis stimulation.Type: GrantFiled: December 8, 1997Date of Patent: November 28, 2000Assignee: Heartport, Inc.Inventors: John H. Stevens, Richard B. Brewer, Daniel C. Rosenman, Hanson S. Gifford, III
