Abstract
An implantable medical device includes an expandable frame that is expandable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable frame including a periphery defined by the expandable frame. A covering spans at least part of the expandable frame. An expandable element is secured relative to the periphery, the expandable element is adapted to seal against an irregular body opening such as an irregular-shaped ostium of a patient's LAA (left atrial appendage).
Claims7
An implantable medical device, comprising:
- an expandable frame expandable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable frame including a periphery defined by the expandable frame;
- a covering spanning at least part of the expandable frame;
- and
- an expandable element secured relative to the periphery, the expandable element adapted to seal against an ostium of an LAA (left atrial appendage);
- wherein the expandable element comprises a plurality of bag filters that each have an open end and a closed end, and each of the plurality of bag filters are arranged around the periphery with the open end facing one direction and the closed end facing an opposing direction;
- and
- wherein at least some of the plurality of bag filters include a coagulant disposed within the bag filters.
An LAAC (left atrial appendage closure) device adapted to fit within an irregular ostium of a patient's LAA (left atrial appendage), the LAAC device comprising:
- an expandable frame expandable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable frame including a periphery defined by the expandable frame, the expandable frame having a circular profile in the expanded configuration;
- a covering spanning at least part of the expandable frame;
- and
- three or more bag filters that are arranged around the periphery.
