Embodiment Construction

[0020] Referring now to the drawings, FIGS. 1 and 2 illustrate a prior art injection port 10 . Injection port 10 has substantially a frusto-conical configuration and includes a body portion 12 , a housing 14 , a sealing element 16 and a conduit element 18 . The body portion 12 is made of a flexible rubberized material with a cavity 20 formed inside. The conduit support 22 is integrally formed in the body portion 12 . Housing 14 is made of corrosion resistant metal and has a reduced, upwardly facing access channel 24 . The sealing element 16 is made of a rubberized material which is easily penetrated by a hypodermic needle or the like and provides a penetrable seal for the channel 24 . Housing 14 and sealing member 16 define an open cavity 20 in injection port 10 for receiving and containing fluid. Conduit element 18 extends through conduit support 22 of body portion 12 and through housing 14 such that conduit element 18 extends into cavity 20 to provide communication betwee...

Abstract

An injection port for subcutaneous placement within a body. The injection port includes an elongated flexible substantially non-rigid body having first and second ends and a wall therebetween. The wall is made from one or more materials such that it will self seal after being punctured by a needle. The body of the device further includs and a fluid reservoir surrounded by the wall. Lastly, the injection port includes a flexible elongated tubular catheter attached to the body which is in fluid communication with the reservoir.

Description

technical field [0001] The present invention relates generally to the field of medicine, and more particularly to medical devices surgically implanted in a patient, in particular to implantable injection or infusion ports such as those used in chemotherapy and adjustable gastric band procedures . Background technique [0002] Surgeons often implant hypodermic ports in patients requiring long-term, periodic fluid injections such as chemotherapy and gastric band adjustments. The injection port is connected to a flexible catheter for delivering fluids to the affected area (subclavian vein, etc.) or gastric band. Existing injection ports consist of a rigid metal or plastic housing with a diameter of approximately 25 mm and a height of approximately 15 mm. A thick silicone septum, captured within the rigid housing, covers the inner chamber, which is in fluid communication with the catheter. The surgeon uses a hypodermic needle to inject the fluid through the silicone septum in...
