Occlusive device with actuatable fixation members

A medical device adapted to occlude a left atrial appendage, comprising:

• an expandable member having a first end region, a second end region;
• at least one fixation member having a first leg, a second leg, and a curved connection region connecting a second end of the first leg and a second end of the second leg, the at least one fixation member configured to move from a delivery configuration to a deployed configuration in response to an expansion of the expandable member;
• wherein the curved connection region is embedded in a securement rib, the securement rib extending circumferentially about the expandable member;
• and
• wherein the expandable member is configured to expand and seal an opening of the left atrial appendage.

A medical device adapted to occlude a left atrial appendage, comprising:

• an expandable member including an inner layer and an outer layer and having a first end region, a second end region, wherein the outer layer includes at least one aperture extending from an inner surface to an outer surface of the outer layer;
• at least one fixation member having a first end and a second end coupled to the expandable member, the at least one fixation member configured to move from a delivery configuration to a deployed configuration in response to an expansion of the expandable member, wherein the at least one fixation member is configured to extend through the at least one aperture in the outer layer when the at least one fixation member is in the deployed configuration;
• and
• wherein the expandable member is configured to expand and seal an opening of the left atrial appendage.
