Abstract
The present disclosure provides improved medical devices for occluding a left atrial appendage. In one embodiment, the medical device includes a temperature activated memory shape foam that is constructed to transition from a first collapsed conformation to a second expanded conformation upon an increase in temperature such that it can expand to provide an occlusive benefit inside a left atrial appendage. In another embodiment the medical device includes a flowable thermoset that is injected into the left atrial appendage where is it cured so that it may assume the conformation of the left atrial appendage and provide an occlusive benefit.
