Publication number: 20220023646Abstract: A leadless biostimulator including an attachment feature to facilitate precise manipulation during delivery or retrieval is described. The attachment feature can be monolithically formed from a rigid material, and includes a base, a button, and a stem interconnecting the base to the button. The stem is a single post having a transverse profile extending around a central axis. The transverse profile can be annular and can surround the central axis. The leadless biostimulator includes a battery assembly having a cell can that includes an end boss. A tether recess in the end boss is axially aligned with a face port in the button to receive tethers of a delivery or retrieval system through an inner lumen of the stem. The attachment feature can be mounted on and welded to the cell can at a thickened transition region around the end boss. Other embodiments are also described and claimed.Type: ApplicationFiled: October 4, 2021Publication date: January 27, 2022Inventors: Thomas B. Eby, Benjamin F.

Patent number: 10105536Abstract: A leadless pulse generator is disclosed herein. The leadless pulse generator has a body, a helical anchor, an electrode, and a sleeve. The body includes a distal end and a proximal end opposite the distal end. The helical anchor distally extends from the distal end. The electrode is at the distal end. The sleeve distally extends from the distal end and has a proximal face and a distal face opposite the proximal face. The proximal face is adjacent the body. The sleeve coaxially extends about the helical anchor and further has a biased state wherein the distal face is near a distal tip of the helical anchor. The sleeve is configured to compress such that the distal face displaces proximally towards the proximal face upon the distal face being forced against the cardiac tissue in the course of the helical anchor screwing into the cardiac tissue.Type: GrantFiled: January 16, 2018Date of Patent: October 23, 2018Assignee: PACESETTER, INC.Inventors: Sondra Orts, Carl Lance Boling, Matthew G. Fishler, Benjamin F. James, IV, Xiangqun Chen

Publication number: 20120151765Abstract: A lead connector end is disclosed herein. The lead connector end may include a generally cylindrical body of unitary construction. The unitary construction may include an electrically non-conductive material extending between three ring contacts imbedded in the electrically non-conductive material. The three ring contacts are offset from each other along a longitudinal length of the unitary body. An electrical conductor extends between two of the three ring contacts and is recessed within an outer circumferential surface of the generally cylindrical body of unitary construction. The electrical conductor is electrically connected to the two of the three ring contacts and forms an integral shunt between the two of the three ring contacts.Type: ApplicationFiled: December 21, 2010Publication date: June 21, 2012Applicant: PACESETTER, INC.Inventors: Benjamin F.

Patent number: 6932517Abstract: An improved connector capable of transferring both energy and electrical signals between an energy generator and an energy transfer device is disclosed. The connector attaches the energy transfer device to the energy generator by rotation about a longitudinal axis. The connector carries at least one contact pad that has a surface on a plane parallel to the longitudinal axis. A line passing through the surface of the contact pad perpendicular to the plane is skew to the longitudinal axis, so that rotation of the connector engages the contact pad with conductive contacts associated with the energy generator in a direction substantially perpendicular to the contact pad.Type: GrantFiled: September 28, 2001Date of Patent: August 23, 2005Assignee: Ethicon Endo-Surgery, Inc.Inventors: Jeffrey S.
