Abstract: Disclosed are methods and devices for containing embolic material within a left atrial appendage of a patient. The device is deployed such that a barrier substantially obstructs the passage of embolic material from the left atrial appendage. The barrier may be self expandable, and may include a polymeric or wire mesh. The device may additionally include a plurality of tissue engagement members, for engaging tissue.

Abstract: Disclosed is an adjustable occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device is removably carried by a deployment catheter. The device may be enlarged or reduced to facilitate optimal placement or removal. Methods are also disclosed.

Abstract: Disclosed is an apparatus for facilitating access to the left atrium, and specifically the left atrial appendage. The apparatus may comprise a sheath with first and second curved sections that facilitate location of the fossa ovalis and left atrial appendage. The apparatus may further comprise tissue piercing and dilating structures. Methods are also disclosed.

Abstract: A dilatation catheter having a balloon (20) of unique and novel configuration which enhances critical properties of the catheter. In at least one section (26), the balloon (20) has a substantially semi-circular cross section when in an uninflated, unwrapped condition. A groove (28) is formed in the resulting flat surface (30) of the balloon (20) accommodate an elongate guide wire lumen (40) and improves fold memory. The guide wire lumen (40) extends along and beside a distal section (23) of the catheter, and is bonded near its distal end into the groove (28) in the balloon (20). At the distal end of the groove (28), the balloon (20) is configured such that the guide wire lumen (40) passes through the balloon wall, such that the distal end of the lumen is disposed in the interior inflation chamber of the balloon (20). In this way, the guide wire (42) follows an essentially straight path in the region of the balloon (20).
