    Abstract: Various fixation techniques for implantable medical device (IMDs) are described. In one example, an assembly comprises an IMD; and a set of active fixation tines attached to the IMD. The active fixation tines in the set are deployable from a spring-loaded position in which distal ends of the active fixation tines point away from the IMD to a hooked position in which the active fixation tines bend back towards the IMD. The active fixation tines are configured to secure the IMD to a patient tissue when deployed while the distal ends of the active fixation tines are positioned adjacent to the patient tissue.

    Abstract: An implantable medical device assembly includes a mounting structure, an electrode protruding from a surface of the structure, between opposing sides thereof, and tissue-penetrating fixation tines, each extending from a corresponding shoulder of the structure surface, adjacent to the opposing sides. In a relaxed condition, each tine extends away from the surface and then bends toward a proximal end of the structure and back toward the surface. In an extended condition, each tine bends toward a distal end of the structure and extends along the corresponding shoulder. A holding member of a delivery tool has opposing sidewalls defining a cavity, wherein each sidewall includes a rail-like edge that fits in sliding engagement with a corresponding shoulder, to deform a corresponding tine into the extended condition, when an operator passes the assembly into the cavity. Applying a push force, to move the assembly back out form the cavity, releases the tines.

    Abstract: A fixation member of an electrode assembly for an implantable medical device includes a tissue engaging portion extending along a circular path, between a piercing distal tip thereof and a fixed end of the member. The circular path extends around a longitudinal axis of the assembly. A helical structure of the assembly, which includes an electrode surface formed thereon and a piercing distal tip, also extends around the longitudinal axis and is located within a perimeter of the circular path. The tissue engaging portion of the fixation member extends from the distal tip thereof in a direction along the circular path that is the same as that in which the helical structure extends from the distal tip thereof. The electrode assembly may include a pair of the fixation members, wherein each tissue engaging portion may extend approximately one half turn along the circular path.
