摘要： A valve insertion unit for holding a heart valve or like prosthetic device to be inserted within the body, for engaging and spreading an expansible valve-receiving ring previously implanted in the body, for moving the valve into position within the ring, releasing the ring over the valve and releasing the valve from the holder. The valve holder is normally biased opened, fingers are used to spread the ring and are biased to a normally closely spaced-apart position, and movement of the holder along the fingers while portions of the holder engage the fingers expands the ring. When the holder, in an extreme axial position of travel, leaves the ends of the fingers, the ring automatically snaps into position to hold the valve in place within the body and the valve holder releases it grip on the valve so the entire instrument may be removed from the body.

摘要： There is disclosed an electrical switch including a plastic housing having a fixed electrical contact mounted therein, an integral plastic actuator including a pair of arms hingedly joined together and a handle for controlling the position of the arms, the outer ends of the arms being respectively swingably connected to the housing at spaced-apart mounting points thereon for snap movement between first and second stable conditions, and a movable electrical contact held against the fixed electrical contact when the arms are in the first stable condition and being held away from the first electrical contact when the arms are in the second stable condition.
