Abstract: An embryo transfer catheter or other medical device has a shaft extruded with two layers. The outer layer is relatively thick and contains gas bubbles sufficient to increase the visibility of the catheter under ultrasound observation but with a density that allows material within the catheter to be viewed by the eye. The inner layer is relatively thin and is free of bubbles so that it provides a smooth bore to the catheter.

Abstract: An embryo transfer syringe has a roller coupled with the rear end of its plunger. The roller is displaceable along an elongate housing extending from the rear of the barrel of the syringe. The roller can be manually engaged through a slot along the housing to rotate it and roll it along the housing thereby smoothly and controllably displacing the plunger.

Abstract: An embryo replacement catheter has a flexible extruded shaft of a transparent polyurethane with a bore extending along its length. Gas bubbles of a diameter in the range 5? to 10? are incorporated into the thickness of the wall of the shaft by adding gas during extrusion. The bubbles are selected to increase the visibility of the catheter under ultrasound imaging whilst still enabling material flowing along the catheter to be seen.

Abstract: An embryo transfer syringe has a roller (30) coupled with the rear end of its plunger (15). The roller (30) is displaceable along an elongate housing (20) extending from the rear of the barrel (10) of the syringe. The roller (30) can be manually engaged through a slot (23) along the housing (20) to rotate it and roll it along the housing thereby smoothly and controllably displacing the plunger (15).

Abstract: An embryo replacement catheter has a flexible extruded shaft of a transparent polyurethane with a bore extending along its length. Gas bubbles of a diameter in the range 5.0 mu. to 10.0 mu. are incorporated into the thickness of the wall of the shaft by adding gas during extrusion. The bubbles are selected to increase the visibility of the catheter under ultrasound imaging whilst still enabling material flowing along the catheter to be seen. The inventive catheter is not confined to embryo replacement catheters.

Abstract: An embryo replacement catheter has a flexible extruded shaft of a transparent polyurethane with a bore extending along its length. Gas bubbles of a diameter in the range 5 .mu. to 10 .mu. are incorporated into the thickness of the wall of the shaft by adding gas during extrusion. The bubbles are selected to increase the visibility of the catheter under ultrasound imaging while still enabling material flowing along the catheter to be seen. The inventive catheter is not confined to embryo replacement catheters.

Abstract: An apparatus for supporting a plurality of objects includes a frame and a drum rotatably attached to the frame so that the drum is rotatable about a horizontal axis. The drum has two ends. The drum includes a plurality of bays, each bay configured to receive one or more objects through an opening in an end of the drum, each bay comprising at least one support element positioned to prevent the one or more objects received within the respective bay from falling out of the respective bay as the drum rotates about the horizontal axis. A method of using a cart for supporting a plurality of objects includes inserting a first object into a first compartment at a first position; rotating the drum about a horizontal axis to move a second compartment to the first position; and inserting a second object into the second compartment.

Abstract: The present invention is a method for cutting a fowl to create a meat cut which includes the radius bone and muscles (meat) adhering to the radius bone. The method involves separating the radius bone and muscles adhering to the radius bone from the carcass of the fowl, and then removing the radius bone and muscles adhering to the radius bone from the carcass of the fowl. The meat cut may be produced with the cutaneous tissues attached to the muscles adhering to the radius bone or with the cutaneous tissues removed from the muscles adhering to the radius bone to produce a skinless meat cut. The resulting meat cut contains a larger percentage of meat and is easier to consume. Alternatively, a portion of the muscles (meat) adhering to the radius bone can be removed to create a meat cut having less meat.

Abstract: A holder for securing a timepiece to an article, such as a backpack, tent, bicycle, or ski coat for example. In a preferred embodiment, the holder comprises a base which is securable to a watch case, and a cover to shield the watch case when it is attached to the base. In one embodiment, the watch case is secured to the base by an elastic strap which is of a width and thickness to fit between the pins of the watch case and the body of the watch case. The cover can comprise a flexible band which is movable from an open position to a closed position, and which can be locked in the closed position. Rings may be provided at opposing ends of the base to connect the base to an article. A belt may be fed through the rings to assist in connecting the holder to the article.

Abstract: A uterine manipulator and associated tip are provided for laparoscopic examinations. The manipulator hereof includes a handle pivotally connected to one end of an elongated frame and a drum positioned at the other end of the frame. The handle is connected to the drum to provide movement of the drum in a plane substantially parallel to the pivot axis of the handle. The handle may be locked relative to the frame in a plurality of desired positions by engagement of a pawl shiftable with the handle in one of a plurality of notches on the frame. The frame is provided with ports along the sides to facilitate cleaning and sterilization. The tip is mounted exclusively remotely to the frame of the uterine manipulator and includes a unique mounting system which maintains the proper orientation of the tip on the drum.

Abstract: Apparatus for feeding workpieces (37, 38) to the collet (3) of a lens lathe comprises a loading device (12) and a magazine (10) for containing a plurality of workpieces (37, 38). The magazine (10) has an opening (11) at one end through which the workpieces (37, 38) are sequentially removable. The loading device (12) is arranged to accept workpieces (37, 38) sequentially from the magazine (10) at a loading station, and to feed them to the collet (3). The loading device (12) has a pair of star wheels (16) for holding a workpiece (37, 38) removed from the magazine (10), and means (34, 35, 36) for positioning said workpiece at the loading station in a predetermined position with respect to the collet (3). The loading device (12) has piston-and-cylinder devices (20) and (23) for moving the star wheels (16) so as to carry said workpiece (37, 38) from the loading station to the collet (3).

Abstract: A surgical aspirator cannula including an elongated body member having a longitudinal aspiration conduit, and a valve assembly supported by the body member and operable to close off the aspiration conduit. The valve assembly includes a thumb switch pad and a plunger having a bore laterally therethrough. When the switch pad is depressed the bore is aligned with the aspiration conduit and suction pressure communicates with the cannula. By sliding it forward, the switch pad can be locked into this open position. When released the plunger is biased upward by a coil spring so that the bore is no longer aligned with the conduit and thereby closing it. A securing assembly removably secures the desired cannula to the forward end of the elongated body member. A generally tubular hub of the securing assembly is pressed fitted into the forward bore of the elongated body member. A ring lock encircles the hub and is rotatable with respect thereto.
