Abstract:
An occlusion device (210) is provided for occluding a left atrial appendage (LA A), including a compliant balloon (230) defining a fluid-tight balloon chamber (232), and an actuating shaft (234), which is disposed at least partially within the balloon chamber (232) for setting a distance between distal and proximal end portions (236, 238) of the balloon (230). A proximal LAA-orifice cover (70) includes a frame (72) and a covering (74) fixed to the frame (72). An orifice- support stent (290) is fixed to and extends distally from the proximal LAA-orifice cover (70), and is generally cylindrical when in a radially-expanded state. Other embodiments are also described.
