Abstract: A catheter comprising, an elongated shaft having a main lumen and an inflation lumen extending along a wall of the shaft. The catheter has a balloon assembly in which an expansible sleeve is joined at spaced zones to an underlying sleeve or tube of a material providing compatible bonding characteristics with the sleeve to facilitate attachment of the balloon onto the shaft.

Abstract: The present invention is concerned with a diagnostic device for collection of body fluids which is especially convenient for taking mid-stream urine specimens. Generally the device comprises a bipartible receptacle having a removable portion which contains a bacteriological medium. The removable portion may be incubated and analyzed subsequent to substantially immediate inocculation of the medium with any pathogens present in the fluid.

Abstract: A syringe and an adapter for a syringe, with the syringe having a chamber for retaining fluid, a plunger having one end received in the chamber for pumping fluid out of the chamber, and an extension member defining a tip of the syringe, and with the adapter having a body member which may be releasably connected to the syringe and a fluid receiving device. A flexible balloon is secured to the extension and body members, and inflates at a predetermined pressure to relieve pressure generated by the syringe.

Abstract: Apparatus for sampling and measuring the pressure of spinal fluid including, a valve, a spinal needle, a manometer and a receptacle. The valve includes a housing having an elongated chamber and a hollow stem extending outwardly from the housing and communicating with the chamber, and the needle is removably connected to the stem and communicates with the stem channel and the chamber. The valve has double-ended plug means biased against both ends of the chamber in sealing engagement to prevent the escape of fluid from the chamber. The manometer is removably connected to an end of the housing and has a hollow stem to retract one end of the plug means in the chamber to establish fluid communication between the chamber and manometer. The receptacle is removably attached to an end of the housing and has a hollow stem to retract one end of the plug means in the chamber to establish fluid communication between the chamber and the inside of the receptacle.
