Abstract: An occlusion device (210) is provided for occluding a left atrial appendage (LAA), 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.

Abstract: A delivery system (10, 110) is provided for delivering and deploying an implantable balloon-based occlusion device (20) including an inflatable balloon (22). The delivery system (10, 110) includes a delivery handle (11), which includes a fluid-retaining chamber (41, 141); a plunger, which is slidingly disposed in the fluid-retaining chamber (41, 141); and a proximal rotatable user-control knob (31). A fluid-conveyance lumen catheter (18) defines a catheter fluid-conveyance lumen (19) in fluid communication with the fluid-retaining chamber (41, 141) and the inflatable balloon (22). A catheter lumen shaft (26) is in reversible connection with the balloon-based occlusion device (20), longitudinally slidable with respect to the delivery handle (11).

Abstract: An instrument for repairing an atrioventricular heart valve, mitral heart valve or tricuspid heart valve includes a first tube having a tube axis defining an axial direction. A leaflet grabbing structure is arranged at a distal part of the first tube and contiguous to the first tube. The leaflet grabbing structure has a main body and a jaw, the jaw being movable relative to the main body. The jaw has a first proximally facing abutment surface and the main body has a second, distally facing abutment surface. The instrument has a needle that is cannulated and forms an inner tube. The needle is releasable from the first tube and movable relative to the main body in axial directions. The leaflet grabbing structure clamps a leaflet of the heart valve between the first and second abutment surfaces, while the jaw allows the needle to extend therethrough.

Abstract: A mechanical compressor system is provided for actuating a bag of a bag valve mask. Rotatable track supports are shaped so as to define respective non-circular closed-loop tracks. Each of one or more mechanical compressors includes two pins that protrude from two sides of the mechanical compressor and engage one of the closed-loop tracks. The mechanical compressors are slidingly coupled to one or more vertical sliders configured to limit the movement of the mechanical compressors to a vertical translational pattern. A bag-coupler is configured to couple the bag to the mechanical compressor system in contact with the mechanical compressors. A motor or a manual crank is arranged to rotate the rotatable track supports, such that the pins move along the closed-loop tracks, causing vertical motion of the mechanical compressors along the one or more vertical sliders, which controls a volume of the bag. Other embodiments are also described.
