An implantable access port for use in transferring fluid transdermally between an external fluid storage or dispensing device and a site within a patient is disclosed. The access port includes a body, at least two reservoirs defined within the access port body, and at least one septum secured to the body and enclosing the reservoirs within the body. The access port also includes reservoir outlets defined within the reservoirs. The access port also has body conduits defined within the body and in fluid communication with the reservoir outlets and external openings defined in the exterior of the body. An implantable access port and system for use in apheresis is also provided that includes an implantable access port, at least one needle, and a catheter that is fluidly connected to the access port.

Dual reservoir implantable access port

An implantable access port for use in transferring a fluid transdermally between an external fluid storage or dispensing device and a site within a patient's body is disclosed. The access port includes a base, a bowl-shaped reservoir defined within the base by a smooth surfaced wall, and a septum secured to the base and enclosing the reservoir within the base. The access port also has an outlet passageway defined within the base and extending in communication with a reservoir outlet defined within the reservoir and an external opening defined in the exterior of the base.

Implantable access port

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.

Contrast medium delivery system and associated method

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.

Luer-type connector

An apparatus is provided for use with a contrast media injector. The injector is of the type including a gas source and a liquid source. The apparatus includes a gas delivery channel connected to the gas source and a liquid delivery channel connected to the liquid source. Two normally closed valves are provided to control flow from the gas and liquid channel. The valves insure that gas and liquid do not simultaneously exit from the channel. The valves minimize inadvertent mixing of the gas and saline downstream of the valves. The gas channel is connected to a gas source using a fitting which also connects electro-conductive wires in the apparatus to a power source. The liquid channel connects to a source of liquid.

Contrast media injector

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.
