A clot retrieval device (9501) for removing occlusive clot from a blood vessel comprises an inner elongate body (9503) and an outer elongate body (9504) at least partially overlying the inner elongate body (9503). The device also comprises an elongate member or shaft (9502) having a proximal end which extends exterior of a patient so that a user can retrieve the stent-basket device and captured clot by retracting the shaft (9502). The outer elongate body (9504) and the inner elongate body (9503) are connected to the distal end of the shaft (9502) and are expandable relative to the shaft (9502) from a collapsed delivery configuration to an expanded deployed configuration. The outer elongate body (9504) is expandable relative to the inner elongate body (9503) to a radial extent which is greater than the radial extent of the inner body (9503) in the deployed configuration. The stent-basket construction of the device creates a reception space (9507) between the inner (9503) and outer (9504) to receive the target clot. The outer body (9504) is configured to allow as much as possible of the clot to migrate through it into the internal reception space (9507). Housing the clot in this reception space rather than pinning it to the wall of the vessel means that the clot is under less compression and can thus be retracted at a lower force. The inner elongate body (9503) and a distal capture net (9505) protect the distal vascular bed from embolisation.

A method of removing clot from a vessel, including delivering a clot retrieval device across the clot, wherein the clot retrieval device includes an inner body having a collapsed delivery configuration and an expanded deployed configuration; and an outer body extending along a longitudinal axis and at least partially overlying the inner body. The outer body includes a first scaffolding section, a second scaffolding section hingedly connected distal of the first scaffolding section; the first and second scaffolding sections of the outer body being expandable to a radial extent which is greater than the radial extent of the inner body in the deployed configuration to define a clot reception space between the inner and outer bodies. The method also includes expanding the clot retrieval device; and urging, by the expanding of the first and second scaffolding sections, at least a portion of the clot therebetween.

A combination lock having a plurality of dials and clutches arranged to control a lock shackle is disclosed. Each of the dials is mounted on a different clutch to form a dial-clutch pair. The clutch has a protrusion and the dial has an open slot dimensioned to receive a protrusion and a plurality of faulty notches. The protrusion is so located that when the lock is in the lock mode, the protrusion in each of the dial-clutch pairs is disengaged from the open slot, allowing the dial to rotate relative to the clutch. Since the clutches do not turn along with the dials and the faulty notches look similar to the open slot, it would be difficult for an intruder to pick the lock by peeking the protrusion of the clutches while rotating the dials.

The invention provides a medical pressure charging control device comprising an outer tube and a threaded push rod located within the outer tube. A movable clamp comprising two clamping arms, a clamp control part connected to the movable clamp and a manipulating part connected with the clamp control part are arranged within the outer tube. When the manipulating part moves from a second position to a first position, the manipulating part drives the clamp control part to move to a locking position, thereby pushing the two clamping arms of the movable clamp to hold tightly the threaded push rod and thus realizing locking of the threaded push rod. When the manipulating part moves from a first position to the second position, the manipulating part drives the clamp control part to move to a release position, thereby pushing the two clamping arms of the movable clamp to loosen the threaded push rod and thus realizing release of the threaded push rod.
