Patent number: 7329234Abstract: A self-occluding catheter includes a body portion for connection to extracorporeal equipment. An elongated tubular extension is provided for insertion into a body cavity. The body portion includes a resiliently biased spool supported therein which is slidable between an open and a closed position for alternately permitting and stopping the flow of blood through the catheter during a given medical procedure. The biasing device for resilient biasing the spool preferably comprises one or more magnets fixed within the body portion which generate a magnetic force for urging the magnetically polarized spool to its closed position.Type: GrantFiled: January 17, 2001Date of Patent: February 12, 2008Assignee: Scimed Life Systems, Inc.Inventor: Michael R. Sansoucy

Patent number: 7318814Abstract: A valve assembly includes a housing defining an aperture, a passageway, and a branch passage. The branch passage extends from the aperture and intersects and communicates with the passageway. The branch passage is disposed at an angle greater than 90 degrees with respect to the passageway. A piston is disposed at least partially within the branch passage and is movable from a first position to a second position. The piston allows communication between the passageway and the aperture when the piston is in the first position, and the piston blocks communication between the passageway and the aperture when the piston is in the second position. An angled seal may be positioned around the piston.Type: GrantFiled: August 12, 2002Date of Patent: January 15, 2008Assignee: Boston Scientific Scimed, Inc.Inventors: Andy H. Levine, Eric E. May, Anthony R. Tremaglio

Patent number: 7258712Abstract: A smoke evacuating system for use during surgical procedures, particularly minimally invasive procedures involving the use of a laser or cautery at a surgical site having an associated higher than ambient pressure, wherein the system includes a filter with a site side and an outlet side and a fluid conduit extending between the surgical site and the filter. The filter includes a filter media and a housing substantially surrounding the filter media with a space between the filter media and the housing to collect condensed vapor. The filter exhibits low resistance or a low pressure drop and resists fluid flow, whereby the higher than ambient pressure is not substantially diminished and generates a fluid flow in the fluid flow path tending to carry smoke to and through the filter.Type: GrantFiled: December 20, 2004Date of Patent: August 21, 2007Assignee: JLJ Medical Devices International, LLCInventors: Leonard S. Schultz, Jeffrey K. Drogue

Patent number: 7252649Abstract: An implantable vascular access device includes a housing having an inlet, an outlet, an interior chamber defined therein and a valve positioned between the inlet and the interior chamber. The valve is subcutaneously manipulated between an open position, in which fluid can flow between the inlet and the interior chamber, and a closed position in which the valve occludes the inlet. The device may include any combination of multiple inlets, outlets and/or interior chambers. In the preferred embodiment, the housing includes two separate interior chambers suitable for the inflow and outflow of a typical hemodialysis procedure. A method for accessing a vascular structure is provided which includes the steps of subcutaneously implanting the device connecting one end of a cannula to the outlet of the device and another end of the cannula to a selected vascular structure. The valve of the device is manipulated to permit fluid communication between the inlet of the device and the selected vascular structure.Type: GrantFiled: January 15, 2003Date of Patent: August 7, 2007Assignee: Boston Scientific Scimed, Inc.Inventor: John Sherry

Patent number: 7223253Abstract: The present invention is directed to a blood aspiration system that is configured to enable various types of aspiration through a working lumen of a catheter. The blood aspiration system facilitates natural aspiration by providing a circuit between a patient's arterial and venous vasculature, and also comprises a manually actuated pump configured to selectively vary rates of aspiration in the working lumen. The blood aspiration system further comprises an external port that allows suction-assisted aspiration or infusion through the working lumen, and further comprises a detachable filter that removes emboli prior to reperfusing blood into a patient's venous vasculature.Type: GrantFiled: July 29, 2002Date of Patent: May 29, 2007Assignee: Gore Enterprise Holdings, Inc.Inventor: Michael Hogendijk

Patent number: 7211074Abstract: A catheter apparatus is provided that includes a tubular body having a distal end. The body defines first and second lumens. The first lumen has a first adapter that includes a first valve biased to seal the proximal end. The first lumen defines a first lateral port and the second lumen defines a second lateral port. A push rod is connected to the first valve for corresponding movement therewith and extends to a tip. The tip includes a first member extending into the first lumen and a second member extending into the second lumen such that the first member seals the first lateral port and the second member seals the second lateral port in a closed position of the tip. The first valve is engageable such that fluid communication is established between the proximal end of the first lumen and the first lumen, and the first and second members move to an open position whereby fluid communication is established.Type: GrantFiled: August 12, 2003Date of Patent: May 1, 2007Assignee: Sherwood Services AGInventor: Michael Sansoucy
