摘要： An apparatus and method for introducing material into an injection site of a patient is disclosed. The device includes a cannula and a carrier. The cannula is inserted into an injection site of a patient. The carrier is connected to an injector containing a volume of material. Material may be pre-loaded into the carrier so that the material is delivered to a distal end of the carrier from the injector and the carrier is thus pre-loaded with material. A portion of the distal end of the pre-loaded carrier is inserted into the cannula and material is delivered to an injection site. The supply section can be rotatable with respect to the longitudinal axis of the inner section.

摘要： A catheter is provided which is disposed for insertion into a fluid-containing cavity of a patient, such as a ventricle of the patient's brain, to drain CSF therefrom. The catheter includes an elongated body provided with a cross-section having an outer surface which is smooth and free of projections, angles or the like which could damage adjacent brain tissue. The elongated body is further provided with proximal and distal ends, a first lumen disposed to serve as a fluid flow passage, and a second lumen extending past a given position located on the elongated body. A titanium wire element is inserted into the second lumen for enabling a neurosurgeon to readily select and adjust the angular orientation between first and second catheter segments, wherein the first and second segments comprise the portions of the elongated body extending between the given position and the proximal and distal ends, respectively. Reinforcing structure is provided around the elongated body to prevent an end of the wire from pushing or rupturing therethrough.

摘要： A method and apparatus for use in coronary bypass surgery procedures wherein the heart remains beating rather than completely stopping the heart, where a blockage is located in the blood vessel for the heart and an incision is made in the vessel adjacent the blockage for the grafting of a vein from another location in the patient's body, and an intraluminal shunt is inserted into the blood vessel to retain the vessel open and allow blood flow through the vessel but prevent blood flow on the exterior of the shunt. The intraluminal shunt comprises a primary perfusion tube having an enlarged bulb or occluder adjacent each end of the tube to cooperate with the interior surface of the vessel, and a secondary perfusion tube intersecting the primary tube at a point either intermediate between the ends of the primary tube or at a location providing a one-third/two-thirds ratio along the primary tube. In the instance of an intermediate secondary tube, the ends of the primary tube extend beyond the bulbs to terminate in beveled end surfaces. The secondary tube is provided with a cap and the ability to interface the secondary tube with a luer type fitting and may be extended beyond the chest wall of the patient.

摘要： Methods and devices for providing a biopsy device with a modified handle and stylet that provides a vacuum to be delivered to the targeted tissue for removal. The vacuum may draw the tissue into the notch where the tissue may then be severed via the cannula. Alternatively, the tissue may be drawn into to the notch after being severed via the stylet and/or cannula. The vacuum may be used to bring a larger amount of tissue into the notch than would otherwise be brought in the notch if no vacuum was used, providing a larger sample through the same size access point.

摘要： A medical drainage system may include a pair of inlet tubes separated by a pump bulb and a valve chamber, where the valve chamber is in fluid communication with a first inlet tube across a one way valve. A second one-way valve may be provided in the entrance to a drainage container at an inlet tube end opposite the pump bulb. The drainage container may be rigid or flexible and may be equipped with emptying means such as a drain valve, connector for suction source, or other emptying/draining means that can be used to partially or wholly void the container contents (e.g., for sampling, testing, or disposal).

摘要： A tray is provided for serving selected food items, wherein the tray is to be used in connection with a separate elongated container, preferably of the type used to retain a beverage. The tray generally comprises a food holding section disposed to carry the food items, and structure for detachably mating or joining the food holding section upon the elongated container, for support thereby. Thus, the container, tray and food thereon can be readily supported and carried by a user as a single unit, by grasping the container with a single hand. In a useful embodiment the center of mass of the tray is substantially aligned along the container axis when the tray and container are joined together. Also, the food holding section and mating structure are usefully formed as an integral structure.

摘要： A shunt tap device is provided for use in sensing CSF pressure data in a shunt implanted in a subject, wherein the shunt comprises a valve having a reservoir, and first and second catheters providing CSF flow paths toward and away from the valve, respectively. The shunt tap device is provided with a hollow needle for temporarily forming an aperture through the wall of the reservoir, to communicate with CSF contained therein. A length of flexible microbore tubing extends from the needle to a coupling, such as a Touhy-Borst connector, which is disposed to receive the pressure transducer component of a pressure monitoring device into a narrow fluid enclosure, collectively formed by the hollow needle, tubing, and a portion of the connector. The fluid enclosure is filled with a saline fluid or the like, having properties similar to CSF. The connector is tightened to seal the saline fluid within the fluid enclosure, and also to retain the pressure transducer in the enclosure, in contact with the saline fluid. By means of such arrangement, CSF pressure data is transmitted from the reservoir to the pressure transducer through the saline fluid, enabling a pressure reading to be provided by the monitor. At the same time, the arrangement allows only negligible amounts of CSF to flow out of the reservoir.

摘要： An improved gas-sensing electrochemical cell for measuring hydrogen cyanide gas in a sample solution. The cell comprises a potentiometric silver ion-sensitive electrode and a reference electrode, both in contact with an internal standard solution comprising an aqueous solution of an argento cyanide complex. A hydrophobic hydrogen cyanide gas-permeable membrane separates the sample solution from the internal solution.
