Filed:

Nov 27, 2000

Appl. No.:

09/724348

Inventors:

Walid N. Aboul-Hosn - Sacramento CA
Michael Guidera - Sacramento CA
William Russell Kanz - Sacramento CA
Richard Milson - Orangevale CA

Assignee:

A-Med Systems, Inc. - W. Sacramento CA

International Classification:

A61B 132

US Classification:

600231, 600215, 600235

Abstract:

Methods and apparatus are described to manipulate the position of the heart to provide surgical access to lateral and posterior portions of the heart. A jack apparatus connected to a surgical retractor can be positioned in the surgical cavity to produce a sideways force on the heart. A tripod apparatus can be used to hold up the heart into a desired position. A band can be attached to the heart to rotate its position. Fingers attached to the bottom of a blade on a surgical retractor can be used to manipulate the hearts position.

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.

International Classification:

A61F 2/38

US Classification:

623 2033, 623 2028, 623 2029

Abstract:

An orthopaedic joint prosthesis may include a first component, a bearing component, and a third component. The first component has a base and a keel protruding from the base to extend into a first bone. The keel's longitudinal axis is offset from a geometric center of the base. The base has a first articular surface and the bearing component has a second articular surface shaped to articulate with the first articular surface. A feature unitary with the first component reversibly attaches to the bearing component. The bearing component has a third articular surface shaped to articulate with a fourth articular surface on the third component. A distraction feature of the bearing component is shaped to provide alignment and/or distraction between the first articular surface and the fourth articular surface during insertion of the bearing component into a joint space between the first and second bones.
