Abstract: A stent crimper is provided for loading a stent onto a catheter in order to provide a stenting assembly that is suitable for use in procedures in conjunction with percutaneous transluminal angioplasty and percutaneous transluminal coronary angioplasty catheters. The crimper has a stent holding member or sheath which supports the stent by its exterior surface so that a balloon of a catheter can be slid within the stent. An elongated wrapping member or belt winds around the sheath. By properly manipulating the belt, the belt applies generally cylindrical radially directed forces onto the sheath and thus onto the stent within the sheath, as well as the balloon beneath the stent, in order to crimp the stent onto the balloon. A procedure is also illustrated by which a stent is crimped onto the balloon by a hand-held crimper which can be discarded after stent delivery and crimping has been completed.

Abstract: An automatic catheter exchange syringe has a biasing means which drives the syringe in a fluid expelling stroke at a single touch. The syringe includes a barrel portion with a plunger slidably disposed therein. The biasing means applies a driving force to the plunger to drive the plunger in a fluid expelling stroke at a predetermined rate. The biasing means may include compression or tension springs or a bifurcated compression spring assembly.

Abstract: A manually operated pumping apparatus which is particularly useful in catheterization procedures has two pumps supported in a housing in a parallel arrangement. The pumps are engaged by a rack and pinion actuating assembly which provides reciprocating linear movement to the two pumps during operation so that one pump performs a pumping stroke while the other pump simultaneously performs a suction stroke. The actuating assembly is driven by a drive assembly which converts rotation of a handle into linear motion usable by the rack and pinion members to drive the two pumps in their reciprocating pumping movements.

Abstract: Various patterns of receptor holes formed in the torso, arms and legs of a plastic toy action figure permit various accessories, also of plastic, having compliant press-in pins to be selectively added to and removed from the toy figure. Additionally, a rotatable coupling mechanism extends through the torso, the coupling mechanism having a receptor hole at each end thereof, the holes in the coupling mechanism being in a predetermined relation with respect to prearranged patterns of receptor holes in the front and rear of the torso. In this way, accessories can be plugged into the ends of the coupling mechanism. The coupling mechanism is provided with two sets of facial teeth or serrations that are normally resiliently urged into engagement but which disengage if the coupling mechanism is subjected to an excessive amount of twisting force, thereby avoiding breakage.

Abstract: A toy figure includes a hollow torso. The arms of the figure are each provided with a ball having a shank extending inwardly therefrom. At the free end of the shank is a disk that is received in an arcuate slot formed by first and second pairs of ribs. The first pair of ribs function to retain the disk so that the ball of each arm is pulled against a beveled annular seat formed in the torso, whereas the second pair of ribs are sufficiently resilient so that they frictionally engage the disk to hold the disk in various positions when the arm with which the disk is associated is swung into various angular positions, thereby retaining the arm in whatever posed relation it has been moved into.

Abstract: The toy action figure has a pair of arms mounted for movement in a wing-like manner and one leg mounted for rocking movement relative to the figure's other leg. An actuating mechanism contained within the hollow torso transmits the rocking leg movement to the arms so that the wind-like movement is achieved. The actuating mechanism includes an arcuate gear rack associated with each of the arms and said one leg, there being several idler gears so that two of the idler are engaged with the two arcuate racks for the arms and the remaining idler gear is engaged with the gear rack for the one leg. The idler gear for one of the arms is additionally engaged with the idler gear for the other arm and also with the idler gear for the one leg.

Abstract: A toy action figure has its arms mounted for swinging movement about laterally spaced vertical axes, and has one leg mounted for rocking movement toward the figure's other leg. The mounting assembly for each arm includes an arm cup and an arm ball, the arm ball having a crank extending through a horizontal slot in its arm cup. An actuating mechanism interconnects the rockable leg with the two cranks, the actuating mechanism including a transmission link connected at its lower end to the rockable leg so that its upper end, which is forked, acts against an angled cam strip that is part of a lever unit provided with two upstanding pins which project into slots formed in the two cranks.
