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.

Patent number: 11400281Abstract: A tine portion of an implantable medical device includes a hook segment and a distal segment terminated by a tissue-piercing tip, wherein the distal segment extends from a distal end of the hook segment to the tip. The hook segment, which is elastically deformable from a pre-set curvature, for example, defined by a single radius, preferably tapers from a first width thereof, in proximity to a proximal end thereof, to a smaller, second width thereof, in proximity to the distal end thereof, wherein the tip has a width that is greater than the second width of the hook segment. Alternately, the tine portion may include a hook segment that is defined by two radii and a straight section extending therebetween.Type: GrantFiled: December 18, 2019Date of Patent: August 2, 2022Assignee: Medtronic, Inc.Inventors: Jonathan L.

Patent number: 9987483Abstract: A tine portion for an implantable medical device includes a hook segment and a distal segment terminated by a tissue-piercing tip, wherein the distal segment extends from the hook segment to the tip. The hook segment, which is elastically deformable from a pre-set curvature, has one of: a round cross-section and an elliptical cross-section, while the distal segment has a flattened, or approximately rectangular cross-section. One or a pair of the tine portions may be integrally formed, with a base portion, from a superelastic wire, wherein the base portion is configured to fixedly attach to the device, for example, being captured between insulative members of a fixation subassembly.Type: GrantFiled: February 27, 2017Date of Patent: June 5, 2018Assignee: Medtronic, Inc.Inventors: Kenneth D Rys, Thomas A Anderson, Vladimir Grubac, Jonathan L Kuhn

Patent number: 9283381Abstract: A tine portion of an implantable medical device includes a hook segment and a distal segment extending therefrom, wherein the hook segment is pre-set to extend along a curvature and is elastically deformable therefrom to an open position. The distal segment includes a tooth and an end that surrounds the tooth, wherein the end includes a pair of legs and a distal arch. The legs extend along a length of, and on opposing sides of the tooth, and the distal arch extends between the legs, distal to a tissue-piercing tip of the tooth. When the hook segment is in the open position, and a force is applied along a longitudinal axis of the device, to push the distal arch of the distal segment against tissue, for initial tissue penetration, the legs of the end of the distal segment bend in elastic deformation to expose the tissue-piercing tip to the tissue.Type: GrantFiled: September 15, 2015Date of Patent: March 15, 2016Assignee: Medtronic, Inc.Inventors: Vladimir Grubac, Jonathan L Kuhn, Kenneth D Rys, Richard W Swenson

Patent number: 9248300Abstract: A relatively compact implantable cardiac medical device includes a wireless communications module, which employs a directional antenna and which is adapted to receive input concerning ventricular wall motion. When the cardiac medical device is anchored to a ventricular wall, transmitter elements of the communications modules are only activated for communication during a detected period of reduced ventricular wall motion. The period of reduced ventricular wall motion may be defined as at least one time interval during which an axis of the directional antenna does not rotate out from a baseline orientation by more than 15 degrees. The communication may be conducted with an external programmer-type device, or with another implanted device, for example, located remote from the heart.Type: GrantFiled: September 9, 2011Date of Patent: February 2, 2016Assignee: Medtronic, Inc.Inventors: Kenneth D.
