Patent number: 8834344Abstract: 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.Type: GrantFiled: September 9, 2013Date of Patent: September 16, 2014Assignee: Maquet Cardiovascular LLCInventors: Walid Najib Aboul-Hosn, Jodi Akin, Michael Guidera, William R. Kanz, Robert G. Matheny

Patent number: 7930014Abstract: A system and method for providing a vascular image are disclosed wherein a single composite display simultaneously provides a first view of a patient including an angiogram image and a second view including an intravascular image rendered from information provided by an imaging probe mounted on a distal end of a flexible elongate member. A cursor, having a position derived from image information provided by a radiopaque marker proximate the imaging probe, is displayed within the angiogram image to correlate the position of the imaging probe to a presently displayed intravascular image and thus provide an easily discernable identification of a position within a patient corresponding to a currently displayed intravascular image. The resulting composite display simultaneously provides: an intravascular image that includes information about a vessel that is not available from an angiogram and a current location within a vessel of a source of intravascular image data from which the intravascular image is rendered.Type: GrantFiled: January 11, 2006Date of Patent: April 19, 2011Assignee: Volcano CorporationInventors: R. Scott Huennekens, Stephen M. Fry, Blair D. Walker, Jon D. Klingensmith, Nancy Perry Pool, Vincent J. Burgess, William R. Kanz
