Publication number: 20150297899Abstract: The invention relates to leadless cardiac pacemakers (LBS), and elements and methods by which they affix to the heart. The invention relates particularly to a secondary fixation of leadless pacemakers which also include a primary fixation. Secondary fixation elements for LBS's may passively engage structures within the heart. Some passive secondary fixation elements entangle or engage within intraventricular structure such as trabeculae carneae. Other passive secondary fixation elements may engage or snag heart structures at sites upstream from the chamber where the LBS is primarily affixed. Still other embodiments of passive secondary fixation elements may include expandable structures.Type: ApplicationFiled: August 14, 2013Publication date: October 22, 2015Applicant: Nanostim, Inc.Inventor: Alan Ostroff

Publication number: 20140074114Abstract: A delivery system for implanting a leadless cardiac pacemaker into a patient is provided. The cardiac pacemaker can include a docking or delivery feature having a through-hole disposed on or near a proximal end of the pacemaker for attachment to the delivery system. In some embodiments, the delivery catheter can include first and second tethers configured to engage the delivery feature of the pacemaker. The tethers, when partially aligned, can have a cross-sectional diameter larger than the through-hole of the delivery feature, and when un-aligned, can have a cross-sectional diameter smaller than the through-hole of the delivery feature. Methods of delivering the leadless cardiac pacemaker with the delivery system are also provided.Type: ApplicationFiled: November 19, 2013Publication date: March 13, 2014Applicant: Nanostim, Inc.Inventors: Alexander Khairkhahan, Alan Klenk

Publication number: 20140039570Abstract: A leadless cardiac pacemaker is provided which can include any number of features. In one embodiment, the pacemaker can include a tip electrode, pacing electronics disposed on a p-type substrate in an electronics housing, the pacing electronics being electrically connected to the tip electrode, an energy source disposed in a cell housing, the energy source comprising a negative terminal electrically connected to the cell housing and a positive terminal electrically connected to the pacing electronics, wherein the pacing electronics are configured to drive the tip electrode negative with respect to the cell housing during a stimulation pulse. The pacemaker advantageously allows p-type pacing electronics to drive a tip electrode negative with respect to the can electrode when the can electrode is directly connected to a negative terminal of the cell. Methods of use are also provided.Type: ApplicationFiled: August 1, 2013Publication date: February 6, 2014Applicant: Nanostim, Inc.Inventors: Kenneth J. Carroll, Alan Ostroff, Peter M. Jacobson
