Patent number: 10531893Abstract: Implant tools and techniques for implantation of a medical lead, catheter or other implantable component are provided. The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An example implant tool for implanting a medical lead includes a rod having a handle and a shaft, and a sheath configured to be placed on the shaft of the rod. The sheath includes a body having proximal end and a distal, a channel formed by the body, the channel extending from the proximal end to the distal end of the body, and an opening that extends along the body of the sheath from the proximal end to the distal end, wherein the channel is accessible via the opening.Type: GrantFiled: March 4, 2014Date of Patent: January 14, 2020Assignee: Medtronic, Inc.Inventors: Kevin R. Seifert, Roger A. Christopherson, Nathan L. Olson, Rebecca L. Poindexter

The implant tools and techniques are particularly useful in implanting medical electrical leads in extravascular locations, including subcutaneous locations. An example implant tool for implanting a medical lead includes a rod and a sheath configured to be placed on the rod. The rod includes a handle, a shaft having a proximal end adjacent to the handle and a distal end, and an attachment feature toward the distal end of the shaft, the attachment feature configured to couple to the medical lead. The sheath is configured to be placed in multiple positions along the rod including a first position in which the sheath does not interact with the attachment feature and second position in which the sheath does interact with the attachment feature.Type: GrantFiled: April 3, 2017Date of Patent: September 3, 2019Assignee: Medtronic, Inc.Inventors: Kevin R.

Patent number: 9642555Abstract: An apparatus for subcutaneous lead guidance includes a flexible guide strap, a navigation catheter and a tunneling tool. The guide strap includes an upper layer having a plurality of retainer formations and a substrate attachable on a patient's skin extending between an incision and a target site. The navigation catheter is coupled to the upper layer via the retainer formations from a first end to a second end of the guide strap. The navigation catheter includes a plurality of position sensors for generating a subcutaneous navigation volume between the incision and the target site when the navigation catheter is coupled to a navigation system. The tunneling tool has a distal portion with a leading end and at least one position sensor on the distal portion for viewing digital representation of the distal portion in relation to the navigation volume on a display coupled to the navigation system.Type: GrantFiled: July 15, 2009Date of Patent: May 9, 2017Assignee: Medtronic, Inc.Inventors: Matthew Bonner, Kenneth Gardeski, Bruce R. Mehdizadeh, Roger Christopherson, Michael R. Neidert

Patent number: 5405140Abstract: A family vacation board game provides a geopolitical map of the United States as a game board, with plural playing paths thereacross. The object of the game is to be the first player to complete a round trip across the board, using a randomly selected playing path each way. Special dice are used for the playing path selection at the beginning of the game and at the beginning of the return trip, and for the determination of the magnitude of each move and drawing of dividend and hazard cards during the course of play. Simulated currency is provided at the beginning of the game, with simulated financial transactions occurring according to the cards drawn. In addition, positions are provided adjacent to the playing paths, which provide an opportunity for players to accrue additional money by correctly answering questions relating to U.S. geography when the players achieve those positions.Type: GrantFiled: September 28, 1994Date of Patent: April 11, 1995Inventors: Joyce A. Terlinden, Roger A. Christopherson
