Abstract

A dual reservoir access port includes a base having proximal and distal fluid reservoirs. The fluid reservoirs each comprise a bottom and a side wall. A dual prong outlet stem projects from a distal end of the base and comprises a first prong and a second prong. A first fluid channel extends through the first prong to the distal reservoir, and a second fluid channel extends through the second prong to the proximal fluid reservoir. A puncture shield is disposed between at least a portion of the second fluid channel and the bottom of the distal fluid reservoir. A needle-penetrable septum is disposed atop of each of the fluid reservoirs. A cap is placed over and around the port base compressing and sealing the septa against the base. A locking collar may be placed over a dual lumen catheter to lock the catheter to the dual prong outlet stem.

First claim

1 - 25 . (canceled)

26 . A septum, comprising:
a needle penetrable body having a ring of material disposed around a circumference of the needle penetrable body, the ring of material comprising: an upper surface having an upper sealing ring; a lower surface having a bottom sealing ring; and, a lateral sealing ring disposed about a circumference of the ring of material

27 . The septum recited in claim 25 , wherein radial compression around the circumference of the needle penetrable body facilitates self-sealing of the septum.

28 . The septum recited in claim 25 , wherein the upper sealing ring has a rounded edge and the lower sealing ring has a rounded edge.

29 . The septum recited in claim 25 , wherein the lateral sealing ring has a rectangular cross section.

30 . The septum recited in claim 25 , wherein the lateral sealing ring is a thin strip of material.

31 . The septum recited in claim 25 , wherein the upper surface is flat and the lower surface is flat.

32 . A septum adapted for use with an access port, comprising:
a needle penetrable body comprising:
an upper dome;
an upper compression zone;
a flange, wherein the flange further comprises a flange upper surface having an upper sealing ring, a flange lower surface having a bottom sealing ring, and a lateral sealing ring disposed about a circumference of the flange; and,
a lower plug; and,
wherein the lower plug extends into a portion of a fluid reservoir of the access port when the septum is placed into the access port.

33 . The septum recited in claim 32 , wherein the lower plug has an outer diameter slightly larger than an inner diameter of the fluid reservoir of the access port.

34 . The septum recited in claim 32 , wherein the upper dome is textured to provide tactile feedback.

35 . An access port, comprising:
a base having at least one fluid reservoir; a cap placed on top of the base, the cap having an opening for each fluid reservoir; a septum comprising:
an upper dome;
an upper compression zone;
a flange, comprising:
a flange upper surface having an upper sealing ring, a flange lower surface having a bottom sealing ring, and a lateral sealing ring disposed about a circumference of the flange; wherein the septum is placed within a portion of the at least one fluid reservoir so that a bottom of the flange is placed on an upper surface of the base; and,
a lower plug to extend into a portion of the at least one fluid reservoir; and,
wherein the cap is placed over the septum to compress the septum against the base.

36 . The septum recited in claim 35 , wherein the upper sealing ring and the lateral sealing ring make contact with the cap and deform to form fluid tight seals.

37 . The septum recited in claim 35 , wherein the bottom sealing ring makes contact with a top surface of the base and deforms to make a fluid tight seal.

38 . The septum recited in claim 35 , wherein the lower plug radially compresses against sidewalls the at least one reservoir.

39 . The septum recited in claim 35 , wherein the upper dome is textured to provide tactile feedback.
