Patent number: 10583272Abstract: Catheter shaft handles and deflection actuators are disclosed. The actuators include at least one pull wire guide wall and a means for anchoring the proximal portion of a pull wire or of a fiber attached to a pull wire. Each actuator is pivotable relative to the catheter handle housing, and may comprise at least one boss for pivoting the actuator relative to the catheter handle housing. The actuators transfer rotational motion based upon user input on a boss into longitudinal motion of a pull wire. The actuators may include a tensioning mechanism comprising a tension adjustment pin and a pin block, wherein the tension adjustment pin is rotatably attached to the pin block to enable adjustment of tension in a pull wire (e.g., during assembly of the catheter handle).Type: GrantFiled: December 1, 2017Date of Patent: March 10, 2020Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Alex Yu, Stephen W. Evans, Genevieve L. Gallagher, Troy T. Tegg

Patent number: 8348937Abstract: An irrigated ablation catheter includes a tubular catheter body having an inner tubular member and an outer tubular member. The catheter body has a proximal portion and a distal portion. The catheter also includes an electrode extending from the distal portion of the catheter body, a flow distributor positioned at least partially within distal portion of the catheter body and at least partially overlapping the electrode, and a flow path extending through the catheter body and the flow distributor. The flow path is configured to provide cooling fluid to an external surface of the electrode.Type: GrantFiled: December 31, 2008Date of Patent: January 8, 2013Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Huisun Wang, Harry A. Puryear, Stephen W. Evans

Patent number: 7527605Abstract: A medical-balloon inflator includes a pump piston assembly, a movable pivot, and an actuator handle. The actuator handle is operatively connected to the movable pivot and is adapted to translate the pump piston assembly to inflate or inflatingly pressurize a medical balloon when the actuator handle is rotated an angular distance about the movable pivot by a user.Type: GrantFiled: June 28, 2005Date of Patent: May 5, 2009Assignee: Ethicon Endo-Surgery, Inc.Inventor: Stephen W. Evans
