Abstract: 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.

The element for indicating use comprises frangible panels or bands which may be disturbed by opening the valve.

Abstract: A liquid drainage system comprising, a receptacle having a chamber to receive and collect the liquid. The system has a drip chamber having a vent with a bacteria filter covering the vent, and an annular wall having a lower edge defining a valve seat, with the seat being disposed at an acute angle relative to the horizontal when the receptacle is in an upright position. The system has an anti-reflux valve comprising a sheet of flexible material extending across the drip chamber such that the sheet is sufficiently large to engage against the seat peripherally around the drip chamber. The system has a device for retaining an upper portion of the valve against an upper portion of the seat, such that a lower portion of the valve flexes away from the seat when the receptacle is placed in an upright position, and the lower portion of the valve flexes against the seat when the receptacle is disposed in a horizontal position.

Abstract: In a device for measuring the approximate peak flow rate of a liquid discharge, the improvement comprising an indicating element bearing water-soluble ink.

Abstract: A cystometry system to measure the pressure-volume relationship in the bladder of a patient from a source of fluid comprising, a catheter having an elongated shaft defining an infusion lumen communicating with an infusion opening adjacent a distal end of the shaft, and a pressure lumen communicating with a pressure opening adjacent the distal end of the shaft. The system has a device for supplying a selected volume of fluid from the source to the bladder through the infusion lumen of the catheter, and a device for measuring the bladder pressure through the catheter pressure lumen.

Abstract: A midstream sampling device comprising, a housing having a chamber, a distal outer mouth defining an outer port, an inner mouth in the chamber defining an inner port, and an outlet opening. The housing has a first cavity communicating between the inner port and the outlet opening, and a second cavity at least partially below the inner mouth and communicating with the outer port. The housing has an elongated depending post having a channel, and an upper aperture communicating with at least one of the cavities. The device also has a receptacle having a chamber communicating with the outlet opening.

Abstract: A device for measuring a discharge of urine comprising, a receiving member having an inlet port to receive the discharge, and a receptacle having a chamber to receive the discharge from the receiving member, and means for measuring a dynamic characteristic of the discharge. The device has a container attached to the receptacle to receive the discharge passing from the receptacle.

Abstract: A bladder hemostatic catheter comprising, an elongated shaft having a lumen extending along the shaft, a tip at the distal end of the shaft, and an opening adjacent the distal end of the shaft communicating between the lumen and the outside of the shaft. The catheter has an inflatable balloon of elastic material covering a distal end section of the shaft, with the balloon having a proximal portion secured circumferentially around the shaft, and with the balloon defining a cavity intermediate the balloon and the shaft communicating with the opening. The balloon is capable of receiving 600 to 1000 cubic centimeters of fluid and assuming a generally spherical shape in an inflated state of the balloon. The catheter has valve means to permit passage of fluid from a source of fluid to the lumen while preventing passage of fluid from the lumen during inflation of the balloon.

The system has a device for supplying a selected volume of fluid from the source to the bladder through the infusion lumen of the catheter, and a device for measuring the bladder pressure through the catheter pressure lumen.

Abstract: A tissue pressure measuring device comprising, a hollow needle and a conduit communicating with the needle at a distal end thereof, with the conduit having a lumen and including a transparent portion having a reference marking. The device has a syringe having a plunger, an outer wall defining a chamber, a barrel received in the chamber and defining a cavity to slidably receive the plunger in sealing engagement with an inner surface of the barrel and permit movement of the plunger between inner and outer positions of the plunger relative to the barrel. The chamber and cavity have a combined volume substantially greater than the volume of the cavity, and the plunger has reference indicia disposed along the plunger to determine the position of the plunger relative to a reference position on the syringe.

Abstract: A catheterization device comprising, a catheter having an elongated shaft defining a drainage lumen, a drainage eye adjacent a distal end of the shaft, and a proximal end. The device has a receptacle having a collection chamber, and a valve assembly communicating with the receptacle chamber and having a channel to receive the proximal end of the catheter. The valve assembly is movable between a first open position establishing communication between the receptacle chamber and the catheter lumen while the catheter is received in the channel, and a second closed position with the receptacle chamber closed from the channel. The valve assembly automatically substantially ejects the catheter from the channel responsive to movement of the valve assembly from the first to second position.

Abstract: A device for measuring a urine discharge comprising, a hollow receptacle having an inlet port adjacent an upper end of the receptacle and a channel below the inlet port to receive the liquid passing through the inlet port. The device measures the velocity of the discharge passing from the port to the channel.

Abstract: A device for measuring the peak flow rate of a urine discharge comprising, a hollow receptacle having a chamber, an inlet port for passage of the discharge into the chamber, and an outlet port for passage of the discharge from the chamber at a predetermined flow rate. The device has a collection container having a closed bottom, a cavity, and an opening adjacent an upper end of the container. The receptacle has an aperture in a lower wall of the receptacle to removably receive the container with the container opening located a predetermined height above the receptacle lower wall in the chamber, such that the discharge passes from the chamber into the container cavity at a predetermined height of the liquid in the receptacle chamber.

Abstract: A device for measuring a liquid discharge comprising, a hollow receptacle having an inlet port adjacent an upper end of the receptacle to receive the liquid discharge.
