    摘要： 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.

    摘要： A medical device configured to be percutaneously delivered to a heart with a catheter of a medical device delivery system. The medical device including a framework and tissue growth member. The framework includes a hub with frame segments extending radially from the hub. The tissue growth member is attached to the framework and extends radially along the framework such that the tissue growth member extends to define an outer layer portion and an inner layer portion where the framework is coupled to the inner layer portion. Further, the tissue growth member extends with multiple voids defined therein such that a filler material is configured to temporarily fill the multiple voids of the tissue growth member.

    摘要： Medical devices, systems and methods for forming an occlusive material for occluding a left atrial appendage of a heart are provided. In one embodiment, the occlusive material includes a foam portion that extends as a single piece, seamless monolithic structure that is sized to couple to an external side of a framework of a medical device. In another embodiment, the occlusive material may include a polymeric laminate. Such polymeric laminate may be adhered to an outer side of the foam portion. Further, various embodiments for forming a polymer laminate are provided.
