An occlusion device () includes a compliant balloon () including an inflation port () for filling and unfilling a fluid into and from a balloon chamber (). A distal tip element () and a proximal base element () are disposed at distal and proximal sides (B,A) of the balloon (), respectively. An elongate actuating element () is disposed longitudinally slidable in a balloon lumen () forming a longitudinal passage () from the proximal side (A) to the distal side (B) of the balloon (), connected to the distal tip element (), and longitudinally moveable with respect to the proximal base element () so as to set a distance between the distal tip element (and the proximal base element (). A locking mechanism () is configured to maintain, between the distal tip element () and the proximal base element (), the distance set using the elongate actuating element ().

Medical occlusion device

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