Publication number: 20130272929Abstract: A sanitization station including a fluid source and one or more plasma generators for generating non-thermal plasma is disclosed. One or more nozzles spray a mist or stream of fluid through plasma generated by the one or more plasma generators to activate the fluid. The fluid is then used to sterilize an object. Another sanitization station includes a chamber for holding a fluid and a plasma generator in fluid communication with the chamber for generating plasma. A circulating source moves the fluid in the chamber past plasma generated by the plasma generator to activate the fluid and one or more spray nozzles coat the surface of an object with fluid that is activated by plasma.Type: ApplicationFiled: March 14, 2013Publication date: October 17, 2013Applicant: EP Technologies LLCInventors: Keith Allen Pelfrey, Robert Gray, Nick E.

Patent number: 7837684Abstract: A method of ablating tissue in the heart to treat atrial fibrillation introduces into a selected atrium an energy emitting element. The method exposes the element to a region of the atrial wall and applies ablating energy to the element to thermally destroy tissue. The method forms a convoluted lesion pattern comprising elongated straight lesions and elongated curvilinear lesions. The lesion pattern directs electrical impulses within the atrial myocardium along a path that activates the atrial myocardium while interrupting reentry circuits that, if not interrupted, would cause fibrillation. The method emulates the surgical maze procedure, but lends itself to catheter-based procedures that do not require open heart surgical techniques. A composite structure for performing the method is formed using a template that displays in planar view a desired lesion pattern for the tissue. An array of spaced apart element is laid on the template.Type: GrantFiled: October 24, 2007Date of Patent: November 23, 2010Assignee: EP Technologies, Inc.Inventors: David K. Swanson, Sidney D. Fleischman, Thomas F. Kordis, David L. McGee

Patent number: 7451807Abstract: A heat exchanger and a method for drying a humid medium. In the heat exchanger an internal cross-over passage, allowing a humid medium to double back on itself in a zone delimited by a barrier, is provided. In a first step the heat exchanger cools itself and in a final step the heat exchanger heats itself. Separation areas allow condensation and collection of water within the heat exchanger. The heat exchanger and method enable drying of compressed air within one and the same heat exchanger package.Type: GrantFiled: January 29, 2004Date of Patent: November 18, 2008Assignees: Advanced Flow Technology Inc., EP Technology ABInventor: Lars Persson

Patent number: 7337836Abstract: A heat exchanger with a leakage vent. A fully brazed heat exchanger has an arrangement preventing the two media inside the heat exchanger from mixing in case of leakage. The heat exchanger includes plates having a pattern of grooves and inlet and outlet connections. The plates are placed in a pack and brazed together so as to form separate channels for two media between alternating pairs of plates. A separation zone is created around the connection so as so block off the medium that is not to reach the respective connection. The other medium can flow on by. A leakage vent to the exterior is provided in the separation zone so as to allow detection of any leakage.Type: GrantFiled: February 17, 1998Date of Patent: March 4, 2008Assignee: EP Technology ABInventor: Lars Persson

Patent number: 7334431Abstract: An evaporator including an evaporating chamber equipped with a drainage. The drainage drains accumulated liquid from the evaporator's lower parts and includes an external expansion driven injector and/or an external pump. The evaporator can be used e.g. in a heat exchanger, e.g. in a heat pump system or air condition system, and the vacuum driven injector can be integrated with an expansion device of the heat exchanger. A condenser can be used together with the evaporator in a heat exchanger of the plate type realizing an integrated superheater/supercooler. This is accomplished by the definition and use of delimited interacting zones through which the cooling medium circulates under heat exchange with itself.Type: GrantFiled: April 15, 2004Date of Patent: February 26, 2008Assignee: EP Technology ABInventor: Lars Persson

Patent number: 7063682Abstract: A catheter assembly having a sheath, which includes a side wall enclosing an interior bore, and a distal region. The assembly also has a bendable catheter tube, which is carried for sliding movement in the interior bore. A pull wire also runs through the interior bore of the sheath, preferably within a lumen. The catheter tube has a distal portion with a coupling which joins the distal portion of the catheter tube and the distal portion of the pull wire. Relative movement of the pull wire and the sheath causes bending of the catheter tube outwardly through the opening, in response to sliding movement of the catheter tube within the interior bore toward the distal region of the sheath.Type: GrantFiled: February 21, 2000Date of Patent: June 20, 2006Assignee: EP Technologies, Inc.Inventors: James G.
