Abstract
An implantable medical device such as but not limited to a left atrial appendage closure (LAAC) device includes an expandable frame that is movable between a collapsed configuration for delivery and an expanded configuration for deployment. The expandable frame may include a plurality of frame members that are biased into the expanded configuration. The expandable frame may include a biasing member. The LAAC device includes a membrane or covering that spans across an end of the expandable frame.
Claims14
An implantable medical device, comprising:
- an expandable frame defining a profile of the implantable medical device, the expandable frame moveable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable frame biased into the expanded configuration, the expandable frame comprising:
- a plurality of frame members each having a proximal end and a distal end;
- and
- a securement member adapted to secure the plurality of frame members at a location between the proximal end and the distal end of each frame member, the securement member adapted to allow the expandable frame to move between the collapsed configuration and the expanded configuration;
- and
- a biasing member that is adapted to bias the expandable frame into the expanded configuration, the biasing member comprising a threaded screw and tether arrangement;
- and
- a covering extending over the proximal end of at least some of the plurality of frame members;
- wherein each frame member extends linearly from the securement member to the proximal end in the collapsed configuration, and each frame member extends linearly from the securement member to the distal end in the collapsed configuration.
A left atrial appendage closure (LAAC) device, comprising:
- an expandable frame moveable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable frame comprising:
- a plurality of frame members each having a proximal end and a distal end, wherein each frame member is substantially straight from the proximal end to the distal end in the collapsed configuration and in the expanded configuration;
- a securement member adapted to secure the plurality of frame members, the securement member adapted to allow the expandable frame to move between the collapsed configuration and the expanded configuration;
- and
- a biasing member that is adapted to move the expandable frame into the expanded configuration when not otherwise constrained, the biasing member comprising a threaded screw and tether arrangement;
- and
- a covering extending over the proximal end of at least some of the plurality of frame members.
A left atrial appendage closure (LAAC) device, comprising:
- an expandable frame moveable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable frame including a plurality of frame members each having a proximal end and a distal end disposed on opposite sides of a securement member secured to each frame member of the plurality of frame members, each of the plurality of frame members adapted to be biased to the expanded configuration when not otherwise constrained;
- and
- a covering extending over the proximal end of at least some of the plurality of frame members;
- wherein in the expanded configuration, the proximal end of each frame member is disposed radially outward of the securement member and the distal end of each frame member is disposed radially inward of the securement member.
