Patent number: 8623010Abstract: An instrument including an elongated shaft and a non-conductive handle is disclosed. The shaft defines a proximal section and a distal section. The distal section forms an electrically conductive tip. Further, the shaft is adapted to be transitionable from a straight state to a first bent state. The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. The instrument is useful for epicardial pacing and/or mapping of the heart for temporary pacing on a beating heart, for optimizing the placement of ventricular leads for the treatment of patients with congestive heart failure and ventricular dysynchrony and/or for use in surgical ablation procedures.Type: GrantFiled: June 9, 2009Date of Patent: January 7, 2014Assignee: Medtronic, Inc.Inventors: Jon M. Ocel, Roderick E. Briscoe, David E. Francischelli, Scott E. Jahns, James R. Keogh, Katherine S. Jolly, Matthew D. Bonner

Patent number: 6615695Abstract: Spiral electrodes and similar structures are manufactured using a high-pressure fluid stream. Specifically, spiral electrodes are made from tubular structures by using a high-pressure water stream to precisely cut, or etch spirals of predetermined geometries to conform to a particular current distribution and conduction requirements. In an embodiment, the high-pressure water stream is tangentially and rotatably oriented against a rotating and translating tubular element. The tangential orientation enables limited cutting or etching of the tubular surface that is only in direct contact with the high pressure stream. Various geometries and spiral structures could be formed by managing the pressure and rotation of the high-pressure water stream source and the rotation and translation of the tubular element.Type: GrantFiled: June 27, 2000Date of Patent: September 9, 2003Assignee: Medtronic, Inc.Inventors: Mark A. Hjelle, Jon M. Ocel, James T. Gates, Randolph Ahnen

Patent number: 6038463Abstract: An implantable electrical lead of the type having a rigid, insulative electrode head carrying an advanceable helical electrode. The electrode head is mounted to an elongated insulative lead body less rigid than said electrode head and which carries an extensible conductor coupled to the helical electrode and an inextensible conductor mechanically coupled to the proximal end of the lead. A second electrode is mounted to said lead body adjacent the electrode head and is coupled to the inextensible conductor. The inextensible electrical conductor is mechanically coupled to the electrode head such that poximally directed traction forces applied to the proximal end of the lead body are applied to the head by the inextensible conductor and not by the second electrode.Type: GrantFiled: September 26, 1997Date of Patent: March 14, 2000Assignee: Medtronic, Inc.Inventors: Timothy G. Laske, Jon M. Ocel

Patent number: 5837006Abstract: In an endocardial, active fixation, screw-in lead of the type having a fixation helix adapted to be rotated in a first, advancement direction out of an electrode head chamber and into cardiac tissue by rotation of a lead connector end and attached lead conductor with respect to an insulating sheath in the first direction and retracted into the chamber by rotation of the lead connector in the opposite, retraction direction, a retraction stop mechanism for preventing over rotation of the helix in the retraction direction. The rotational motion of the lead conductor is transmitted to the helix by a connecting assembly and is translated into axial advancement and retraction of the helix by a guide cooperating with the helix turns. A retraction stop mechanism stops rotation of the helix in the retraction direction upon full retraction of the helix into the chamber and allows rotation of helix in the advancement direction.Type: GrantFiled: September 10, 1996Date of Patent: November 17, 1998Assignee: Medtronic, Inc.Inventors: Jon M. Ocel, Gregory A. Boser, Timothy W. Holleman

Patent number: 5728149Abstract: A cardioversion/defibrillation lead, and method of manufacture thereof, for location in a human heart. An elongated lead body having an insulating outer sheath extends between proximal and distal ends thereof, and an elongated defibrillation conductor within the lead body extends from a connector at the proximal end to a distal end at a predetermined location along the lead body length. A spiral band defibrillation electrode extends in spiral turns around the exterior of the insulating outer sheath for a pre-determined defibrillation electrode length. The defibrillation electrode is fabricated of a single tube of body compatible, electrically conductive material having first and second tube ends and an inside diameter selected to fit over the outer sheath and the internally disposed defibrillation lead conductor.Type: GrantFiled: December 20, 1995Date of Patent: March 17, 1998Assignee: Medtronic, Inc.Inventors: Timothy G.
