  • Publication number: 20110218566
    Abstract: Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes an occlusion member and may also include a stabilizing member. The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue in-growth onto the occlusion member. Methods are also disclosed.

  • Patent number: 6650923
    Abstract: Disclosed is an access catheter for identifying and providing access through a tissue structure such as the fossa ovalis on the intraatrial septum. The access catheter comprises an elongate flexible tubular body having a proximal and a distal end, and a retractable piercing structure such as a needle carried by the distal end. A detector such as a red, green, and blue light detector is associated with the access catheter, such that placement of the distal end of the catheter against the fossa ovalis can be detected. The piercing structure is thereafter advanceable to provide access to the left atrium through the fossa ovalis.
