description Devices, methods and systems are provided for occluding a left atrial appendage. In one embodiment, a medical device includes a cover portion and a foam anchor portion with a flexible member coupled therebetween. The cover portion is configured to be positioned over an ostium of the left atrial appendage. The foam anchor portion extends between a proximal end and a distal end to define a length and an axis defined along the length of the foam anchor portion. The foam anchor portion defines a curved external surface radially extending relative to the axis such that the curved external surface extends between the proximal and distal ends of the foam anchor portion. The foam anchor portion is configured to self-expand to provide an outward biasing force from the curved external surface such that a circumferential surface area of the curved external surface biases against tissue of the left atrial appendage.
