Patent number: 7316667Abstract: A tool for protecting a cardiac stimulating lead from damage upon passing through a hemostasis valve of a vascular introducer in the course of an implantation procedure comprises a splittable, peal-away sheath that is rendered sufficiently rigid by a tool dilator or placement of the lead body within the sheath so that the combination can be forced through a self-closing aperture formed through the hemostatic valve member. The use of the tubular sheath in breaching the self-closing aperture shields the lead electrodes and any covering that may be present from becoming distorted as well as from contamination by silicon oil commonly found in vascular introducers having a hemostasis valve.Type: GrantFiled: March 6, 2003Date of Patent: January 8, 2008Assignee: Cardiac Pacemakers, Inc.Inventors: Curtis C. Lindstrom, James D. Kadera

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.

Publication number: 20020111664Abstract: A cardiac lead designed for implantation in the vasculature of the left side of the heart comprising a flexible lead body having a central lumen, a removable terminal pin, electrodes electrically coupled to the removable terminal pin, a mechanism for securing the electrodes in the proper position in the vasculature and a mechanism for sealing the central lumen after implantation to prevent body fluids from invading the lumen. The cardiac lead can be implanted or explanted using either a guidewire, a guide catheter or both.Type: ApplicationFiled: April 5, 2002Publication date: August 15, 2002Applicant: Cardiac Pacemakers, Inc.Inventors: Jeffrey T. Bartig, Stuart R. Chastain, Gwen Crevensten, John E. Heil, Curtis C. Lindstrom, Aaron W. Jahnke

Patent number: 6321122Abstract: A single-pass endocardial lead electrode adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity includes a lead body with a circumferential outer surface. 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 second electrode is adapted for positioning and fixation to the wall of the atrium of the heart. A passive fixation element may be used as part of the second electrode. The lead body also includes a curved portion which facilitates the positioning and passive fixation of the second electrode.Type: GrantFiled: July 22, 1998Date of Patent: November 20, 2001Assignee: Cardiac Pacemakers, Inc.Inventors: Avram Scheiner, Curtis C. Lindstrom, Robert S. Booker, III, Yayun Lin, Peter T. Kelley, John E. Heil, William Hsu, Ronald W. Heil, Jr.
