    Abstract: An example fixation component for an implantable medical device (IMD) includes a base and a plurality of tines configured be deployed with a target deployment stiffness to engage tissue a target implant site while maintaining a target deflection stiffness after deployment. The base defines a longitudinal axis of the fixation component and is fixedly attached near the distal end of the IMD. Each tine is spaced apart from one another around a perimeter of the distal end of the IMD and extend from the base. A shape of each tine is selected to control each of the target deployment stiffness and target deflection stiffness.

    Abstract: 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 tines when so fixated in the tissue provide a fixation energy. The deployment energy and the fixation energy of the tines are equivalent.

    Abstract: 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.

    Abstract: 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.

    Abstract: An implantable pacemaker system includes a housing having a proximal end and a distal end. A control electronics subassembly defines the housing proximal end, and a battery subassembly defines the housing distal end. A distal fixation member extends from the housing distal end for fixing the housing distal end at an implant site. A pacing extension extends from the housing proximal end and carries a pacing cathode electrode. The pacing extension extends the pacing cathode electrode to a pacing site that is spaced apart from the implant site when the pacemaker is deployed in a patient's body.

    Abstract: A relatively compact implantable medical device includes a fixation member formed by a plurality of fingers mounted around a perimeter of a distal end of a housing of the device; each finger is elastically deformable from a relaxed condition to an extended condition, to accommodate delivery of the device to a target implant site, and from the relaxed condition to a compressed condition, to accommodate wedging of the fingers between opposing tissue surfaces at the target implant site, wherein the compressed fingers hold a cardiac pacing electrode of the device in intimate tissue contact for the delivery of pacing stimulation to the site. Each fixation finger is preferably configured to prevent penetration thereof within the tissue when the fingers are compressed and wedged between the opposing tissue surfaces. The pacing electrode may be mounted on a pacing extension, which extends distally from the distal end of the device housing.

    Abstract: An implantable medical device includes ventricular and atrial portions, and a flexible leadlet that extends therebetween. An open channel of the atrial portion, formed along a core thereof, is sized to receive the leadlet therein, when the leadlet is folded over on itself. An interventional medical system includes the device and a delivery tool; a tubular sidewall of the tool defines a lumen and has a tether extending therein. A slot formed in the sidewall extends proximally from an open end thereof, coincident with a distal opening of the lumen. When the atrial portion is contained within the lumen, a segment of the leadlet extends alongside the atrial portion; another segment of the leadlet, being folded over on itself, proximal to the atrial portion, has the tether engaged therewith. The slot may allow passage of the leadlet therethrough, when the atrial portion is positioned for deployment through the distal opening.
