Filed:

Sep 20, 1999

Appl. No.:

09/398723

Inventors:

Lyndall Erb - Montaro CA
Dany Berube - Fremont CA
Robert Matheny - Carmel IN

Assignee:

International Classification:

A61B 1818

US Classification:

606 33, 606 41, 607101, 607156, 600387

Abstract:

A securing apparatus for selectively securing an ablating element of an ablation instrument proximate to a targeted region of a biological tissue. The securing apparatus includes a support base affixed to the ablation instrument relative the ablating element, and having a support face adapted to seat against the biological tissue proximate to the ablation element. The support base further defines a passage having one end communicably coupled to a vacuum source and an opposite end terminating at an orifice at the support face. The support face together with the biological tissue forms a hermetic seal thereagainst during operation of the vacuum source to secure the ablation instrument thereagainst. Essentially, the hermetic seal and the vacuum source cooperate to form a vacuum force sufficient to retain the ablation device against the biological tissue.

International Classification:

A61N 132

US Classification:

607118, 607 9

Abstract:

A method and apparatus for facilitating coronary surgery on the beating heart wherein the vagus nerve is electrically stimulated to purposely temporarily stop or substantially reduce the beating of the heart under precisely controlled conditions. The apparatus controllably applies electrical stimulus to pre-selected locations along the vagus nerve and to pre-selected nerve branches related to the heart. The apparatus includes several clip and probe configurations for establishing electrical contact with the vagus nerve. Such purposely caused temporary stoppage or substantial reduction of the beating of the heart facilitates procedures such as suturing of an anastomosis which would otherwise be more difficult because of the motion induced by the beating heart.

International Classification:

A61B 1728

US Classification:

600232, 606207

Abstract:

An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade. The superior blade is preferably pivotally coupled to the spreader member such that it naturally rises as the blades are separated. Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, increase a surgeons working space and visual access for the dissection of an internal mammary artery. A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeons working area.

International Classification:

A61M001/10

US Classification:

600 16, 623 31

Abstract:

A cannulation system for cardiac support uses an inner cannula disposed within an outer cannula. The outer cannula includes a fluid inlet for placement within the right atrium of a heart. The inner cannula includes a fluid inlet extending through the fluid inlet of the outer cannula and the atrial septum for placement within at least one of the left atrium and left ventricle of the heart. The cannulation system also employs a pumping assembly coupled to the inner and outer cannulas to withdraw blood from the right atrium for delivery to the pulmonary artery to provide right heart support, or to withdraw blood from at least one of the left atrium and left ventricle for delivery into the aorta to provide left heart support, or both.

Abstract:

A prosthetic tissue valve for aortic, pulmonary, mitral or tricuspid valve replacement is described herein. A sewing ring for use with the prosthetic tissue valve is also described. The valve can have a circumference that is a predetermined distance larger than the circumference of an annulus in a defective valve. The valve can be substantially planar in an unstressed position before attachment at the annulus and substantially non-planar upon attachment in a biased position at the annulus. Methods are provided for placing the valve as described herein in the biased position within the annulus of the defective valve.
