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: 20030163184Abstract: A single-pass endocardial lead electrode adapted for implantation in, on or about the heart and for connection to a system for monitoring or stimulating cardiac activity includes a lead body which is adapted for implantation within a single chamber of the heart, or multiple chambers of the heart. The lead includes a first distal end electrode which has a first electrical conducting surface. The lead body also has a second electrode which has a second electrical conducting surface. The first and second electrodes are either passively or actively attached to the wall of the heart. The lead body also includes a curved portion which facilitates the positioning of the second electrode. The main lead body alternatively includes a recess into which an atrial lead body and an active fixation element attached to one end can travel from a recessed position to a position for fixation to the wall of the heart. The lead is attached to a pulse generator for producing pulses to the multiple sites within the heart.Type: ApplicationFiled: January 6, 2003Publication date: August 28, 2003Applicant: Cardiac Pacemakers, Inc.Inventors: Avram Scheiner, William Hsu, David M.

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: 6141594Abstract: A single pass endocardial lead is provided which is adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity. The lead includes a main body which extends into two distal leg portions, each having at least two electrodes coupled therewith. The first leg is for positioning within the ventricle of the heart. The second leg is for positioning within the atrium of the heart. Both the first leg and the second leg are bipolar and are adapted for positioning and fixation to the heart wall. The first and second legs can be fixated to the heart wall using either passive or active fixation structures. A movement assembly for advancing a helix comprises an externally threaded collar which engages with an internally threaded housing or housing insert.Type: GrantFiled: July 22, 1998Date of Patent: October 31, 2000Assignee: Cardiac Pacemakers, Inc.Inventors: David M.
