Patent number: 10668251Abstract: The invention provides a deflectable catheter capable of forming many variable radius spiral forms from a single, flexible, distal end section. In one aspect, the catheter employs a variable radius control wire to extend or deform a pre-formed loop structure into a three dimensional spiral-like form or geometry. The ability of a single catheter to create a multitude of shapes and sizes allows users to access to a number of anatomical areas without changing the catheter during a procedure or treatment. In another aspect, the invention encompasses methods of producing deflectable variable radius catheters, where two or more regions of the catheter having common control wires are fused or formed onto one another.Type: GrantFiled: July 10, 2018Date of Patent: June 2, 2020Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Duy Nguyen, Sheldon Nelson, Elizabeth Nee, Guy P. Vanney

Patent number: 8170692Abstract: An implant tool for use with an endocardial or other implantable lead having an extendable/retractable active fixation tip includes a housing, a shaft rotatably supported by the housing, and a shaft rotation mechanism for rotating the shaft through a predetermined angular travel. The shaft includes a lead attachment portion for selectively coupling a lead to the shaft such that the lead is rotatable with the shaft. The implant tool may include a control tab slidably supported by the housing, wherein longitudinal movement of the control tab actuates the shaft rotation mechanism. The shaft rotation mechanism may include a gear train, an electric motor, a double acting spring mechanism, or a retractable tape wound around the shaft. The gear train includes an input member coupled to the control tab and an output gear coupled to the shaft. The input member meshes with an input gear supported by the housing.Type: GrantFiled: January 29, 2010Date of Patent: May 1, 2012Assignee: Pacesetter, Inc.Inventors: Frank Truong, Virote Indravudh, Shimul Sengupta, Jayaram Sundararajan, Elizabeth Nee, Ryan Buesseler
