Publication number: 20050113631Abstract: 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: November 12, 2003Publication date: May 26, 2005Inventors: Steven Bolling, Shawn O'Leary, Robert Pecor, Brad Sharp, Anthony Viole, Wolfgang Werner

Patent number: 6889082Abstract: 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: GrantFiled: November 6, 2002Date of Patent: May 3, 2005Assignee: Orqis Medical CorporationInventors: Steven F.

Publication number: 20040236173Abstract: 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: June 28, 2004Publication date: November 25, 2004Inventors: Anthony Viole, Laksen Sirimanne, Steven F. Bolling, Shawn O'Leary, Robert Pecor, Ryan Kelly, Wolfgang Werner, Masoud Beizai

Publication number: 20040138519Abstract: 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. Lumens extending from the proximal end to each of these distal ends provide for blood circulation within one or between two blood vessels. At least one aperture in one of the lumens positioned near the proximal end provides for active perfusion of blood to the patient's vasculature downstream of where the aperture resides in the vasculature when the catheter is inserted into the patient for treatment. The inventive catheter may comprise a third lumen positioned entirely within the patient's vasculature, providing passive perfusion of blood to the patient's vasculature downstream of where the third lumen resides in the vasculature when the catheter is inserted into the patient for treatment.Type: ApplicationFiled: December 22, 2003Publication date: July 15, 2004Inventors: Anthony Viole, Laksen Sirimanne, Steven F.

Patent number: 6712816Abstract: Methods, systems, and kits for treating breast tissue rely on transferring energy to or from cells lining an individual breast duct. Energy can be introduced into the breast duct, e.g., by filling the duct with an electrically conductive medium and applying radiofrequency energy to the medium. Other energy forms could also be used, such as light, ultrasound, radiation, microwave energy, heat, cold, direct current, and the like. By treating individual breast ducts, cancerous and pre-cancerous conditions originating in the duct can be effectively treated.Type: GrantFiled: May 15, 2002Date of Patent: March 30, 2004Assignee: Cytyc Health CorporationInventors: David Hung, Chris Ken, Julian Nikolchev, Susan Love, Shawn O'Leary

Patent number: 6413228Abstract: The invention provides methods, devices and systems for collecting breast ductal fluid comprising cellular material and other useful markers for analysis. The methods typically comprise access of at least one breast duct and collecting materials from that duct separate from all other ducts in the breast. The devices comprise ductal access devices that provide the opportunity to collect fluid from a single duct separate from all the other ducts in the breast. The systems employ the methods and devices that used together provide systems for analysis of a breast condition in a patient specific to accessed breast ducts. The methods, devices and systems are particularly useful for indentification of breast precancer or cancer in patient.Type: GrantFiled: December 28, 1999Date of Patent: July 2, 2002Assignee: Pro Duct Health, Inc.Inventors: David Hung, Christopher G.

Patent number: 5693015Abstract: A balloon catheter includes a flexible small-diameter guide wire provided with an enlarged-diameter distal end portion, and a flexible elongated tubular shaft with at least one dual-function fluid-conducting lumen adapted to both receive the guide wire extending therethrough, and to communicate pressurized inflation fluid to a distal balloon of the catheter. A distal orifice of the catheter communicates with the balloon and is provided with selective valving means for releasably engaging sealingly with the enlarged distal end portion of the guide wire. Apparatus is disclosed for axially moving the guide wire to effect engagement and disengagement of the enlarged distal end portion with the selective valving means of the catheter shaft. A torquer device is also provided by means of which the guide wire may be rotated relative to the catheter shaft for steering of the guide wire along a vascular pathway.Type: GrantFiled: June 6, 1995Date of Patent: December 2, 1997Assignee: Advanced Cardiovascular Systems, Inc.Inventors: Blair Walker, Manouchehr Miraki, William Rice, Kambiz Ghearzadeh, Brett Trauthen, Hye Lee, Greg Welsh, Henry Nita, Shawn O'Leary
