Patent number: 7491163Abstract: A multilumen catheter that maximizes the blood flow into and out of the patient's vasculature while also providing for passive and/or active perfusion of tissue downstream of where the catheter resides in the vasculature. The inventive catheter comprises a proximal end, a first distal and a second distal end with first and second lumens extending from the proximal end to each of these distal ends to provide for blood circulation within one blood vessel or between two different blood vessels. The second lumen, and any additional lumens so desired, may be positioned coaxially with or radially around the first lumen. Redirecting means is provided at a distal end of at least one of said lumens for directing blood in a direction generally opposite of the direction of flow through said lumen.Type: GrantFiled: May 3, 2006Date of Patent: February 17, 2009Assignee: Orqis Medical CorporationInventors: Anthony Viole, Laksen Sirimanne, Steven F. Bolling, Shawn O'Leary, Robert Pecor, Ryan Kelly, Wolfgang Werner, Masoud Beizai

Publication number: 20080275290Abstract: An extracardiac pumping for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart, and methods of using same. One embodiment of the intravascular extracardiac system comprises a pump with inflow and outflow conduits that are sized and configured to be implantable intravascularly through a non-primary vessel, whereby it may positioned where desired within the patient's vasculature. The system comprises a subcardiac pump that may be driven directly or electromagnetically from within or without the patient. The pump is configured to be operated continuously or in a pulsatile fashion, synchronous with the patient's heart, thereby potentially reducing the afterload of the heart.Type: ApplicationFiled: May 3, 2006Publication date: November 6, 2008Inventors: Anthony Viole, Laksen Sirimanne, Steven F. Bolling, Shawn O'Leary, Robert Pecor, Ryan Kelly, Wolfgang Werner, Masoud Beizai
