Patent number: 8562555Abstract: The control of fluid introduction into and out of body conduits such as vessels, is of great concern in medicine. As the development of more particular treatments to vessels and organs continues it is apparent that controlled introduction and removal of fluids is necessary. Fluid delivery and removal from such sites, usually referred to as irrigation and aspiration, using fluid exchange devices that control also need to be considerate of potential volume and/or pressure in a vessel or organ are described together with catheter and lumen configurations to achieve the fluid exchange. The devices include several electrically or mechanically controlled embodiments and produce both controlled and localized flow with defined volume exchange ratios for fluid management. The applications in medicine include diagnostic, therapeutic, imaging, and uses for the introduction or removal of concentrations of emboli within body cavities.Type: GrantFiled: July 18, 2006Date of Patent: October 22, 2013Inventors: John M. MacMahon, Thomas G. Goff, Brian K. Courtney

Patent number: 8435225Abstract: Apparatus and methods are described for effective removal of emboli or harmful fluids during therapeutic and diagnostic vascular procedures, such as angiography, balloon angioplasty, stent deployment, laser angioplasty, atherectomy, and intravascular ultrasonography. A catheter with an occluder mounted at its distal end creates an occlusion proximal to the lesion and provides a pathway for introducing a treatment catheter. Prior to, during or subsequent to the procedure, suction is activated to establish retrograde flow to remove emboli from the site. Additionally, a thin catheter with a distal fluid ejection nozzle may be introduced distal to the treatment site to rinse emboli from the treatment site. The suction flow and/or ejected fluid flow may be varied in a pulsatile manner to simulate regular blood flow and/or perturb settled emboli into being captured that may otherwise not be collected. The method establishes a protective environment before any devices enter the treatment site.Type: GrantFiled: July 30, 2004Date of Patent: May 7, 2013Assignee: Fox Hollow Technologies, Inc.Inventors: Brian K. Courtney, John M. MacMahon, Thomas G. Goff
