Abstract: A medium- and high-pressure pulsed jet generator (1) for injecting controlled volumes of at least one medical liquid (7) includes a high-pressure chamber (2) and at least one connector (24) for at least one flexible pouch containing the medical liquid. The flexible pouch/es (6) is/are connected, via a connection tube, to a hydraulic sequencer (28) which is mounted in the high-pressure chamber, is exposed to the pressure inside the chamber (2), sequences the liquid discharged from the flexible pouch into a pulsed jet (11), is composed of a hydraulic connection (20) that is designed as or includes a deformable flexible sleeve (29) hydraulically communicating with the pouch/es (6) at the inlet and with a hand-held intervention element (40) or a catheter at the outlet, and includes hydraulic stops (31, 32) that are disposed on both sides of the flexible deformable sleeve (29) and are operated using a control element (33).

Abstract: The micro-electromechanical (MEMS) actuator comprises a hot arm member and a cold arm member. The cold arm member comprises at least two longitudinally spaced-apart flexors. The actuators may also be constructed with at least one among the hot arm member and the cold arm member comprising at least one spring section. The stress in this improved MEMS actuator is more uniformly distributed, thereby reducing the mechanical creep and improving its reliability as well as its operation life.

Abstract: Micro-electromechanical systems (MEMS) actuators and switches exhibiting geometries and configurations providing superior operating characteristics and longer lifetimes.

Abstract: The micro-electromechanical (MEMS) switch comprises a first double-sided cantilever MEMS actuator attached to a substrate and movable in two opposite directions, and a second cantilever MEMS actuator attached to the substrate. In use, the first MEMS actuator is moved in either directions to distribute the stress more uniformly, thereby reducing the mechanical creep and improving its reliability as well as its operation life.
