    Abstract: An implantable medical device having barbs reducing in height and/or changing angle as the implantable medical device transitions for an expanded state to a constrained state is disclosed which may lessen the risk of injury associated with the removal and/or repositioning of a deployed device. Within the main body of the device may be positioned a plurality of fixation struts having an end secured to the main body and a barb end exiting the main body at a point of egress and extending radially outwards from the main body. The fixation struts may be secured to the main body such that the distance between the point of attachment of the secured end of a fixation strut and the respective point of egress from the main body its free barb forming end is greater in the constrained than expanded state.

    Abstract: An example occlusive implant is disclosed. The example occlusive implant includes an expandable framework configured to shift between a first configuration and an expanded configuration and a fixation member disposed along the expandable framework. The fixation member includes a first engagement portion and an anchor portion. Further, the first engagement portion is designed to be secured to the expandable framework and the anchor portion extends away from an outer surface of the expandable framework.

    Abstract: A left atrial appendage closure implant may include a support frame including a first bend extending from a proximal collar to a second bend, a first segment extending from the second bend to a third bend, a second segment extending from the third bend to a fourth bend, and a third segment extending from the fourth bend to a distal collar, wherein the support frame is actuatable from a first constrained position to a second flowering position to a third mid-deployment position to a fourth unconstrained position. An implant may include a self-expanding support frame having a circumference and a central longitudinal axis, a membrane disposed over at least a portion of the support frame, and a plurality of anchors arranged into a first row and a second row such that the first row and the second row form a staggered pattern about the circumference of the support frame.
