Publication number: 20210252283Abstract: A fixation mechanism of an implantable medical device is formed by a plurality of tines fixedly mounted around a perimeter of a distal end of the device. Each tine may be said to include a first segment fixedly attached to the device, a second segment extending from the first segment, and a third segment, to which the second segment extends. When the device is loaded in a lumen of a delivery tool and a rounded free distal end of each tine engages a sidewall that defines the lumen, to hold the tines in a spring-loaded condition, the first segment of each tine, which has a spring-biased pre-formed curvature, becomes relatively straightened, and the third segment of each tine, which is terminated by the free distal end, extends away from the axis of the device at an acute angle in a range from about 45 degrees to about 75 degrees.Type: ApplicationFiled: May 3, 2021Publication date: August 19, 2021Inventors: Xin Chen, Michael D.

Patent number: 10898707Abstract: Methods and systems of making a medical electrical lead type having a set of tines. A system for implantation of a lead medical electrical lead in contact with heart tissue, comprises an elongated lead body; a set of curved tines mounted to and extending from a distal end of the lead body, the tines having a length (dD) and an effective cross sectional area, and a delivery catheter. The delivery catheter encloses the lead body and has a distal capsule portion enclosing the tines. The tines exerting a spring force against the capsule and provide a stored potential energy. The delivery catheter has an elastic, not stiff and low column strength ejection means for advancing the lead and tines distally from the capsule and fixating the tines within the heart tissue, the controllable and the stored potential energy of the tines together provide a deployment energy. The tines when so fixated in the tissue provide a fixation energy. The deployment energy and the fixation energy of the tines are equivalent.Type: GrantFiled: November 8, 2018Date of Patent: January 26, 2021Assignee: Medtronic, Inc.Inventors: Michael D.
