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.
