Patent number: 11559679Abstract: A fixation mechanism of an implantable lead includes a plurality of depressions of an outermost surface of the lead and a relatively flexible sleeve mounted around the outermost surface. The depressions are spaced apart from one another along a length, and each extends circumferentially, wherein a longitudinal center-to-center spacing between each adjacent depression is uniform along the length, and each depression is of substantially the same size. The sleeve has an internal surface in sliding engagement with the outermost surface of the lead, and an external surface, in which suture grooves are formed. A longitudinal center-to-center spacing between adjacent suture grooves may be substantially the same as, or a multiple of, the longitudinal center-to-center spacing between adjacent depressions of the outermost surface of the lead. The sleeve may also include a ridge protruding from the internal surface, aligned with, or offset (by center-to-center spacing of depressions) from, the grooves.Type: GrantFiled: March 30, 2020Date of Patent: January 24, 2023Assignee: Medtronic, Inc.Inventors: Kevin R. Seifert, Maggie J. Pistella, Thomas D. Brostrom, Keith D. Anderson, Gareth Morgan

Publication number: 20210369386Abstract: An implantable medical lead may include an electrode at a distal portion of the lead that is configured to monitor or provide therapy to a target site. The lead may include a visible indicator that is visible to the naked eye of a clinician at a medial portion of the lead that is configured to indicate when the electrodes of the lead are longitudinally and radially aligned properly to monitor or treat the target site. A clinician may insert the lead into the patient using an introducer sheath inserted to a predetermined depth into the patient and subsequently aligning the distal portion of the lead by orienting the indicator at an entry port of the introducer sheath.Type: ApplicationFiled: August 12, 2021Publication date: December 2, 2021Inventors: George W. McFall, Thomas D. Brostrom, Mark T. Marshall, Dina L. Williams, Megan Harris, Keith D. Anderson, Maggie J. Pistella

Publication number: 20210204879Abstract: Various embodiments of a bioelectric sensor device and a method of utilizing such device are disclosed. The bioelectric sensor device includes a central portion and an arm extending from the central portion, where at least a portion of the arm extends along an arm axis. The central portion includes an anatomical alignment mark adapted to align the central portion with an anatomical feature of a lateral surface of a torso of a patient. Further, the arm is adapted to be disposed on an anterior or posterior surface of the torso. The bioelectric sensor device also includes a sensor disposed on the arm along the arm axis, and a connector electrically connected to the sensor.Type: ApplicationFiled: July 31, 2020Publication date: July 8, 2021Inventors: Daniel M. Gelfman, Paul M. Narr, Elizabeth A. Schotzko, Lindsey T. Dahlberg, Jordyn Reich, Nicole Parks, Maggie J. Pistella

Publication number: 20200129758Abstract: A medical electrical lead includes a plurality of longitudinally spaced electrodes and a fixation element helix located between a proximal-most pair of adjacent electrodes of the plurality, so that a piercing tip of the helix is centered therebetween. A grip sleeve of a connector terminal of the lead may be gripped to apply a torque which is transferred to the fixation element, thereby engaging the helix thereof with tissue. The lead may include means for limiting the amount of torque that can be transferred from the connector terminal grip sleeve to the fixation element. The torque limiting means may be an external contour of the lead along a length thereof that extends between the connector terminal grip sleeve and the fixation element. The plurality of lead electrodes may further include a distal-most pair of adjacent electrodes, between which the lead extends in pre-set a curvature.Type: ApplicationFiled: October 23, 2019Publication date: April 30, 2020Inventors: William Clemens, Vania Lee, Maggie J.
