Patent number: 12042658Abstract: A biostimulator, such as a leadless pacemaker, having electrode(s) coated with low-polarization coating(s), is described. A low-polarization coating including titanium nitride can be disposed on an anode, and a low-polarization coating including a first layer of titanium nitride and a second layer of platinum black can be disposed on a cathode. The anode can be an attachment feature used to transmit torque to the biostimulator. The cathode can be a fixation element used to affix the biostimulator to a target tissue. The low-polarization coating(s) impart low-polarization to the electrode(s) to enable an atrial evoked response to be detected and used to effect automatic output regulation of the biostimulator. Other embodiments are also described and claimed.Type: GrantFiled: March 11, 2021Date of Patent: July 23, 2024Assignee: PACESETTER, INC.Inventors: Gene A. Bornzin, Wesley Alleman, Tyler J.

Patent number: 12042651Abstract: A method of pacing a His bundle of a patient heart using a stimulation system including a memory, a pulse generator, a stimulating electrode and at least one sensing electrode includes applying a plurality of impulses through the stimulating electrode to induce a plurality of responses from the patient heart. Each impulse of the plurality of impulses is delivered at a different impulse energy corresponding to a respective output setting of the stimulation system. The response characteristics for each of the plurality of responses are measured and each impulse is assigned a classification based on whether the respective response characteristics indicate capture of one or both of the His bundle and a ventricle of the patient heart. The output setting and classification for each impulse is then stored in the memory.Type: GrantFiled: March 18, 2021Date of Patent: July 23, 2024Assignee: Pacesetter, Inc.Inventors: Julie Prillinger, Gene A.

Publication number: 20240157154Abstract: Described herein are implantable medical devices (IMDs), and methods for use therewith. In certain embodiments, a controller of an IMD controls when a pacing capacitor of the IMD is charged using a first voltage, when the pacing capacitor is being charged using a second voltage, and when the pacing capacitor is discharged to deliver a pacing pulse between anode and cathode electrodes of, or electrically coupled to, the IMD. By selectively charging the pacing capacitor for a portion of a charge duration using the second voltage, that is greater in magnitude than the first voltage that is used for delivering the pacing pulse, a magnitude of a polarization artifact superimposed on an evoked response within a cardiac electrical signal, sensed using a sensing circuit of the IMD, is reduced compared to if the pacing capacitor were instead charged using the first voltage for the entire charge duration.Type: ApplicationFiled: September 29, 2023Publication date: May 16, 2024Applicant: Pacesetter, Inc.Inventors: Gene A.
