Abstract: A fixation member component, for example, employed by a relatively compact implantable medical device, includes a plurality of fingers; each finger includes a first segment extending from a fixed end of the corresponding finger, and a second segment extending from the corresponding first segment to a free end of the corresponding finger. Each first segment is elastically deformable from a relaxed to an extended condition, and from the relaxed to a compressed condition, and includes a peripheral portion and a central cut-out portion, framed by the peripheral portion. In the compressed condition, a free tip of the cut-out portion of some or all of the fingers may lodge against opposing tissue surfaces, via a spring force of the compressed fingers. Each second segment and cut-out portion is preferably configured to prevent penetration thereof within tissue at the implant site.

Abstract: A medical fixation device which may include an elongate body with a proximal portion, a distal portion, and define a longitudinal axis extending therethrough. A first fixation member on the proximal portion of the elongate body and a second fixation member on the distal portion of the elongate body may also be included with the medical fixation device. The first fixation member and the second fixation member may each have a delivery configuration in which the first fixation member and the second fixation member are collapsed along the longitudinal axis, and an anchoring configuration in which the first fixation member and the second fixation member each extend radially outward from the elongate body, define a septal aperture therebetween, and each have a tip facing away from each other.

Abstract: The medical device may comprise an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough. Also, the medical device may include an expandable element coupled to the distal portion of the elongate body and in fluid communication with the lumen. The expandable element may define a first end and a second end, the second end being proximal to the first end. The medical device may further include a cannula surrounding at least a portion of the elongate body and the cannula may define a proximal end and a distal end. The distal end of the cannula may be disposed proximal and adjacent to the second end of the expandable element. An outer dimeter of the cannula may be substantially equal to or lesser than an outer diameter of the expandable element when inflated. The medical device may be maneuvered through a patient's body.

Abstract: 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.
