Abstract

A device that is implantable to provide access to multiple body sites for the administration or withdrawal of fluids. A hollow port has a self sealing septum on one end and an outlet at an opposite end. A catheter is connected to the outlet. The septum and outlet are positioned to be substantially in-line.

Claims

1. A body implantable access device comprising;

a hollow port, said port having an inlet an outlet and an infusion chamber therebetween, a self sealing septum disposed in and covering said inlet, and said self-sealing septum positioned on said port at substantially a right angle to said outlet such that a needle puncturing said septum will be substantially in line with said outlet.

2. The implantable device of claim 1 further comprising means to mount a catheter at said outlet and a flexible catheter mounted on said means to mount a catheter to provide fluid access to a portion of the body in which said device is implanted.

3. The implantable device of claim 2 wherein said means to mount a catheter comprises a hollow connector one end of which is inserted into said outlet of said port and the other end having annular barbs engaging said catheter.

4. The implantable device of claim 1 further comprising means to anchor said port subcutaneously at an angle substantially parallel with the skin line at the implantation site.

5. The implantable device of claim 4 wherein said means to anchor comprises first and second shoulder portions provided on said port, said shoulder portions extending circumferentially around said port.

6. The implantable device of claim 4 wherein said means to anchor comprises first and second circumferential recesses provided on said port.

7. The implantable device of claim 4 wherein said means to anchor comprises a tie-down member having means to mount said body, said tie-down member further including a flat portion defining a sutures area.

8. The implantable device of claim 7 wherein said flat portion includes a series of through-holes for passing sutures.

9. The implantable device of claim 7 wherein said flat area includes a fabric mesh for passing sutures.

10. The implantable device of claim 1 wherein said self sealing septum is angled at a shallow acute angle with respect to said outlet.

11. A body implantable device providing access to an internal portion of a living body for the administration and withdrawal of fluids comprising:

a hollow port made of a biocompatible material, said port having wall portions defining an inlet, an outlet and an infusion chamber therebetween, a self sealing septum member positioned to cover said inlet at substantially a right angle to said outlet to provide a target for a needle used in the administration and withdrawal of fluids, said infusion chamber located upstream of said outlet and blocked from the inlet by said self-sealing septum, and said self sealing septum oriented in said inlet such that a needle passing through said system will stop in said infusion chamber area and will be substantially in line with said outlet.

12. The implantable device of claim 11 further comprising means to mount a catheter at said outlet and a flexible catheter mounted on said means to mount a catheter to provide fluid access to a portion of the body in which said device is implanted.

13. The implantable device of claim 12 wherein said means to mount a catheter comprises a hollow connector one end of which is inserted into said outlet of said port and the other end having annular barbs engaging said catheter.

14. The implantable device of claim 11 further comprising means to anchor said port subcutaneously at an angle substantially parallel with the skin line at the implantation site.

15. The implantable device of claim 14 wherein said means to anchor comprises first and second shoulder portions provided on said port, said shoulder portions extending circumferentially around said port.

16. The implantable device of claim 14 wherein said means to anchor comprises first and second circumferential recesses provided on said port.

17. The implantable device of claim 14 wherein said means to anchor comprises a tie-down member having means to mount said body, said tie-down member further including a flat portion defining a sutures area.

18. The implantable device of claim 17 wherein said flat portion includes a series of through-holes for passing sutures.

19. The implantable device of claim 17 wherein said flat area includes a fabric mesh for passing sutures.

20. The implantable device of claim 11 wherein said self sealing system is angled at a shallow acute angle with respect to said outlet.
