Publication number: 20060270965Abstract: 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: ApplicationFiled: May 3, 2006Publication date: November 30, 2006Inventors: Anthony Viole, Laksen Sirimanne, Steven Bolling, Shawn O'Leary, Robert Pecor, Ryan Kelly, Wolfgang Werner, Masoud Beizai

Publication number: 20060270963Abstract: A percutaneous cannula is provided that directs blood into a vessel of a patient. The cannula includes a main cannula portion and a tip portion. The tip portion directs blood-flow in a direction generally counter to the direction of flow through the lumen. The cannula is configured to prevent blood-flow exiting the distal end from immediately discharging against a wall of the vessel.Type: ApplicationFiled: May 3, 2006Publication date: November 30, 2006Inventors: Steven Bolling, Shawn O'Leary, Robert Pecor, Brad Sharp, Anthony Viole, Wolfgang Werner

Publication number: 20060270893Abstract: 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 provides a vascular graft that has a first end that is sized and configured to couple to a non-primary blood vessel and a second end that is fluidly coupled to a pump to conduct blood between the pump and the non-primary blood vessel. An outflow conduit is also provided that has a first end sized and configured to be positioned within the same or different blood vessel, whether primary or non-primary, through the vascular graft. The outflow conduit is fluidly coupled to the pump to conduct blood between the pump and the patient. The vascular graft may be connected to the blood vessel subcutaneously to permit application of the extracardiac pumping system in a minimally-invasive procedure.Type: ApplicationFiled: May 3, 2006Publication date: November 30, 2006Inventors: Steven Bolling, Anthony Viole, Shawn O'Leary

Publication number: 20060270894Abstract: 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 30, 2006Inventors: Anthony Viole, Laksen Sirimanne, Steven Bolling, Shawn O'Leary, Robert Pecor, Ryan Kelly, Wolfgang Werner, Masoud Beizai

Publication number: 20050131385Abstract: A perfusion cannula system for directing blood through the vasculature of a patient comprises a cannula body having a proximal end, a distal end, and at least one lumen extending therebetween. The perfusion cannula system enhances blood flow past the cannula when the cannula body resides within the patient. A first balloon can be located on an exterior surface of the cannula body and the balloon can be deployed within the vasculature whereby space may be provided between a vessel wall and the cannula body. A cannula body can have an aperture formed therein in fluid communication with a lumen. A sleeve can be carried by the cannula and can be configured to be moveable relative to the aperture to selectively cover and uncover the aperture as desired.Type: ApplicationFiled: December 12, 2003Publication date: June 16, 2005Inventors: Steven Bolling, Anthony Viole, Shawn O'Leary, Robert Pecor
