Abstract: A central venous catheter is provided having an outer tubular member and an inner tubular member that are preferably formed as a single integrated tube containing polymer material of different durometer and varying amounts of radiopaque filler material. The polymer durometer of the inner tubular member is higher than the polymer durometer of the outer tubular member. The percentage by weight of the filler material contained in the inner tubular member is higher than that of the outer tubular member. The combination of the higher durometer inner tubular member and the lower durometer outer tubular member along the length of the tube provides the desired tensile strength, hardness, chemical resistance and fatigue resistance and at the same time provides the desired flexibility and radiopacity.

Abstract: A catheter is provided that has at least one lumen which extends from a proximal end of the catheter to a distal end of the catheter. The catheter also has a catheter hub that has a body with a proximal end, a distal end, an exterior surface, and defining an interior cavity. The exterior surface of the body further defines at least one opening. At least one opening is defined therein the proximal end, and at least one opening is defined therein the distal end. The catheter also has a means for measuring and displaying the number of times that the catheter is injected with an infusate at a pre-determined pressure.

Abstract: A fluid injection device including a multi-lumen catheter and a coupler is provided. The catheter has a common tube portion containing a set of lumens and a distal end adapted to be placed in a blood vessel. At least two extension tubes extend from the common tube portion. Output connectors of the coupler are coupled to the catheter's extension tubes such that they are combined into an input lumen which is coupled to a fluid source to simultaneously inject the fluid into the catheter's extension tubes. The simultaneous injection of the fluid into the multi-lumen catheter's extension tubes provides an even pressure on the lumen walls of the catheter, a higher flow rate and a balanced thrust at the exit of the catheter.

Abstract: A device cooperating with a pump for guiding a contrast medium from a source thereof to a catheter for delivery to a patient's vascular system. The device comprises a dual check valve, a tubular member, an in-line check valve and a three-port stopcock. The dual check valve has an inlet port connectable to the source of contrast medium, an inlet-outlet port connectable to the pump, and an outlet port coupled to the tubular member. The in-line check valve is connected to the tubular member at a point spaced from the dual check valve for preventing fluid flow towards the dual check valve. The stopcock connected at a first port to the in-line check valve, a second port of the stopcock being operatively connectable to the catheter. Using this device, medical personnel infuses contrast medium into the patient from the source without having to disconnect any element from the device during the infusion process.

Abstract: A luer-type adapter has a dual instead of a single set of engaging screw threads. A proximal and a distal screw thread on the hub engage proximal and distal screw threads on the collar of the connector to provide at least twice the engaging or sealing force between the tapered surfaces of the stem and hub which are forced together by rotating the collar relative to the hub to engage the two sets of threads. The diameters of the engaging distal screw threads have to be sufficiently great so that the proximal screw thread on the hub can pass under the distal screw thread on the collar in order to effect proximal as well as distal engagement. An O-ring mounted on an untapered distal segment of the stem engages an untapered inner hub surface to provide additional sealing force which is particularly useful where gas is being provided through the adapter.

Abstract: A catheter for introducing material into the vascular system is provided. The catheter includes an elongated catheter body having a side wall defining a catheter lumen. The catheter body has a proximal portion. Material can be introduced into the catheter lumen at its proximal portion. The catheter body has a distal portion. The distal portion has a single wall in an exit zone. At least one pressure responsive exit is formed in the side wall of the distal portion of the catheter body. The pressure responsive exit permits material to exit from the catheter lumen in response to a pressure over a first predetermined amount while preventing material from entering into the catheter lumen at a pressure less than a second pre-determined amount.
