  • Patent number: 4601710
    Abstract: A trocar assembly (70) formed from a trocar tube subassembly (74) and a separable, interfitting trocar subassembly (72). The trocar tube assembly includes a head (112) having a bore (120) into which a trocar tube (116) is fitted and a manually operated slide valve assembly (118) mounted transversely of the bore in the head. The valve has a bore (134) through it that may be aligned with the bore in the head by movement of the valve. The trocar subassembly includes a head (76) that has a bore (92) extending partly through it in which a trocar obturator (82) and a concentric tubular shield (86) are mounted such that the shield is capable of limited axial movement relative to the obturator between a normal, extended position in which the shield effectively covers the piercing tip (84) of the obturator and a retracted position in which the tip is exposed. The obturator and shield are inserted through the bore in the trocar tube subassembly head, the slide valve bore and the trocar tube.

  • Patent number: 4596551
    Abstract: A tubing clamp for firmly retaining flexible tubing without occluding flow through it and for forcing the tube into straight and open configuration. The tubing clamp rests on a platform member and comprises a pair of jaws positioned in opposed relation to each other and pivotally mounted on the platform member to be pivotally movable between open and closed positions. Facing surfaces of the jaws defines recesses that together define a tube port in the closed position of substantially the outer diameter of the tubing intended for retention therein. The tube has a parting line, and the jaws also define overlapping members at the parting line to prevent pinching of tubing occupying the tube port in the parting line as the jaws are moved to closed position.

  • Patent number: 4596564
    Abstract: A medical applicance of a stationary surgical suction device comprised of an ultramalleable formable tube that may readily be shaped in situ. The tube is comprised of a formable, flexible tubular plastic ultramalleable material, having at least one fluid conveying lumen and includes a parallel oriented malleable member that is disposed within the plastic material so as to be frictionally interrelated to the tubular plastic material. A method of fabricating the lumen includes the steps of furnishing a plastic tubing having at least a pair of lumens, furnishing an elongated malleable member of cross-section complementary to that of one of the lumens and of a size in excess of the size of the lumen, dilating the lumen to allow insertion of the malleable member into the lumen and allowing the lumen to shrink onto the malleable member to effect a frictional engagement with the lumen.

  • Patent number: 4543091
    Abstract: For pre-operative radiography preparatory to stereotaxic lateral extradural disc puncture (e.g. as disclosed in U.S. Pat. No. 3,941,127) the patient is placed on his side and a radiographic film is exposed from which the surgeon calculates position and angle of needle approach to the disc before the actual operation begins. An X-ray opaque marker device similar to a ruler is located parallel and adjacent to the patient at the level of the midsaggital plane. Markings and numbers on the marker device show on the exposed film. With prolonged X-ray exposure, the image of the marker may be "burned". The present device provides a series of radiopaque shields which may be interposed between the marker and the film to reduce burn-out of the image of the marker on the film. A convenient stand supports and stores the marker and one or more shields so that they may be individually and selectively raised and turned into operative position.

  • Patent number: 4531935
    Abstract: A cardioplegia/air aspiration cannula assembly for delivering cardioplegic fluid to and for aspirating air from the aorta during surgery. The assembly includes a hub having a single needle portion. The needle portion has an inner cannula which extends through the hub and defines an inner lumen through which the cardioplegic fluid is injected. An outer cannula is coaxially positioned over the inner cannula and is diametrally spaced therefrom to define an outer lumen. A plurality of holes are formed in the sides of the outer cannula through which air can be aspirated. The outer lumen defined by the space between the inner and outer cannulae is in fluid communication with a passageway passing through a side branch of the hub which can be connected to a vacuum source.

  • Patent number: 4515586
    Abstract: A pre-filled chamber having a piston plug at one end and a stopper at the other end. The chamber is filled with a powdered medicament that is to be intermixed with a diluent in a container. Rotatable attachments join the chamber containing the powder with a receptacle on the container. The powdered medicament is expelled from the chamber by the force of a plunger acting on the piston plug. The stopper at the end of the chamber containing the powder serves as a mounting for a piercing tip which breaks a membrane over the neck of the container allowing fluid connection between the chamber and the container and transferral of the powdered medicament from the chamber to the container.

  • Patent number: 4392850
    Abstract: A sterile container for a medicinal material which is to be intermixed in an I.V. solution wherein the container serves as a mixing device as well as a portion of an I.V. administration apparatus. The device of this invention includes a container which is closed at opposing ends by pierceable diaphragm portions. Extending from one end is a piercing pin having a diaphragm piercing portion which can pierce the diaphragm when it is moved inwardly into the container and also provide a fluid passageway for the container contents. At the opposing end a diaphragm is housed in a closure with a flexible end wall and a tubular guide section for the piercing pin of an I.V. administration set. The container therefore serves a dual function of holding a fluid material such as a powder in a sterile condition yet serving as a component of an I.V. set to thereby afford a quick and simple procedure for mixing additive components into an I.V. administration set.
