Publication number: 20240100325Abstract: A fixation component includes tines extending from a base portion of the fixation component. Each tine is elastically deformable between a pre-set position and an open position. Each tine includes a hook segment extending from a proximal end near the base portion to a distal end. Each tine also includes a distal segment extending from the distal end of the hook segment to a tissue-piercing tip. When positioned in the pre-set position, the hook segment extends along a pre-set curvature that encloses an angle between 135 degrees and 270 degrees, and the distal segment extends away from a longitudinal axis of the fixation component.Type: ApplicationFiled: December 5, 2023Publication date: March 28, 2024Inventors: Jonathan L.

Publication number: 20230233865Abstract: A system includes harvester circuitry configured to charge a battery for a medical device using a displacement of a harvester mass, one or more accelerometers configured to detect a motion associated with the harvester mass, and processing circuitry. The processing circuitry is configured to determine, with the one or more accelerometers, motion information for the implanted medical device during a time range that occurs when the harvester circuitry charges the battery using the displacement of the harvester mass. The processing circuitry are further configured to determine a harvester output generated by the harvester circuitry during the time range and output an indication of a potential failure of the harvester mechanism based on the motion information and the harvester output.Type: ApplicationFiled: November 29, 2022Publication date: July 27, 2023Inventors: Michael P. Campbell, Richard J. O'Brien

Patent number: 11154207Abstract: An implantable medical device, such as a sensor for monitoring a selected internally detectable physiological parameter of a patient, is attached to a fixation assembly that is deployable within the patient to position and orient the sensor to enable it to perform its function. The fixation assembly is formed having at least one flexible asymmetric connector where each fixation member includes a plurality of loops, wherein a first loop of the plurality of loops has a maximum pitch that is different from a maximum pitch of a second loop of the plurality of loops. The attachment of the housing and the fixation assembly includes providing a tubular member that is welded to the housing and crimped over a section of the fixation assembly.Type: GrantFiled: December 14, 2016Date of Patent: October 26, 2021Assignee: Medtronic, Inc.Inventors: Michael P. Campbell, George Patras, Michael A. Schugt, Amir R. Zamiri, Richard J. O'Brien, Ruth N. Klepfer
