Patent number: 8209035Abstract: A lead having an extendable and retractable fixation mechanism has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring disposed at the distal end of the lead provides information during the implantation process.Type: GrantFiled: June 23, 2008Date of Patent: June 26, 2012Assignee: Cardiac Pacemakers, Inc.Inventors: David M. Flynn, Michael Brenzel, Jason Skubitz, Larry L. Hum, Carol Werlein, Christopher Paul Knapp, Gregory R. Ley, Jason Alan Shiroff, Brian David Soltis

Publication number: 20040122498Abstract: A lead including a lead body configured into a pre-formed J-shape, and a shocking electrode coupled proximate the distal end of the lead body and located distally from a bottom of the pre-formed J-shape, wherein the lead is adapted to be placed within a heart in a J-shaped configuration with the lead extending through the right ventricle and the electrode positioned within a pulmonary artery. The lead can include a distal end adapted for being passively fixated within a pulmonary artery.Type: ApplicationFiled: December 19, 2002Publication date: June 24, 2004Inventors: Yongxing Zhang, James O. Gilkerson, Christopher Paul Knapp

Patent number: 6501990Abstract: A lead having an extendable and retractable fixation mechanism has a rotating terminal pin at the terminal end which rotates the fixation mechanism at the distal end. As the terminal pin is rotated, the fixation mechanism is extended or retracted from the distal end of the lead. A threaded collar allows for the fixation mechanism to smoothly extend and retract from the lead, and allows for a 1:1 turn ratio between the terminal pin and the fixation mechanism. A fluoroscopic ring disposed at the distal end of the lead provides information during the implantation process. The lead includes a terminal assembly having an outer terminal ring, a terminal pin, and an insulative sleeve disposed between the outer terminal ring and the terminal pin. The insulative sleeve is coupled with the outer terminal ring with a snap-fit connection.Type: GrantFiled: December 23, 1999Date of Patent: December 31, 2002Assignee: Cardiac Pacemakers, Inc.Inventors: Gregory L.

Patent number: 6361780Abstract: A drug delivery device is described comprising a porous biocompatible solid having at least one therapeutic drug within its pores, the therapeutic drug being removable from the pores by immersion in an aqueous solution. This may also be described as a drug delivery device comprising a porous annulus comprising a biocompatible solid having at least one therapeutic drug within its pores, the therapeutic drug being removable from the pores by immersion in an aqueous solution, the annulus having a top outer surface with an outside diameter, an inner surface with an inside diameter, and a side surface, at least one of the side surface and the top outer surface having openings of the pores exposed on that surface. The device may comprise pores having an average size of the greatest dimensions within the pores of between about 10−6 and 10−1 mm. The device may have a medical device or component of a medical device pass through an opening in the annulus.Type: GrantFiled: November 12, 1998Date of Patent: March 26, 2002Assignee: Cardiac Pacemakers, Inc.Inventors: Gregory R.
