1. A conformable left atrial appendage occlusion device, comprising:

  • an expandable tubular body having a compressible open cell foam sidewall, a proximal, occlusive end for facing a left atrium following implantation of the device in a left atrial appendage, a distal end for facing into the left atrial appendage following implantation of the device in the left atrial appendage, and a longitudinal axis extending therethrough, the tubular foam body having a mean diameter in an unconstrained expansion; and

    a self-expandable support carried within the expandable tubular body such that the foam sidewall provides a cushion between the support and the wall of the left atrial appendage following implantation, the support comprising a plurality of struts forming a plurality of apexes;

    wherein compression of the device from a diameter of about 25 mm to a diameter of about 15 mm along a minor axis transverse to the longitudinal axis causes no more than about a 5 mm reduction in the mean diameter.
