Patent number: 8593830Abstract: DC-to-DC converters are protected from damage by, among other things, monitoring and controlling forward and reverse currents in their transformer primary windings. The currents are discontinued if their values fall outside a predetermined range or if they flow during a portion of the switching cycle in a manner that would result in cross-conduction. Power switches in these converters are also protected from damage by adjusting the maximum duty cycles of these converters to vary with their input voltages. In this way, the maximum voltage across the power switches is kept within a relatively narrow range. These protective features can be combined in any number of ways to fit the application at hand.Type: GrantFiled: June 20, 2011Date of Patent: November 26, 2013Assignee: Maxim Integrated Products, Inc.Inventor: Thong Anthony Huynh

Publication number: 20080312664Abstract: A medical device is disclosed for tissue, body lumen and/or cavity closure inside a body of a patient. In one particular application, the medical device can be used for minimally invasive access and closure of a left atrial appendage of the heart. The medical device generally includes a tool used for grasping the appendage, a closure member, and at least one tool to deploy, control, and position the closure member for closing the appendage. The device can also include an expander tool for expanding the working area around the left atrial appendage to improve visibility during the procedure. In other embodiments, the medical device may include other tools, for example an imaging tool for viewing the target area and/or other tools that are considered useful in a left atrial appendage closure procedure.Type: ApplicationFiled: May 12, 2008Publication date: December 18, 2008Applicant: EPITEK, INC.Inventors: Earl Bardsley, Jianlu Ma, Jean Paul Rasschaert, Thomas J.
