1. A port comprising:
- (a) a port body having a septum retainer therein, wherein the septum retainer comprises a collar and a base, the collar having an inner surface extending about a circumference of the collar, wherein the inner surface of the collar is configured to have a substantially straight taper at a predetermined angle, wherein the base is configured to have a substantially straight taper that complements the substantially straight taper of the inner surface of the collar, wherein the base is further configured to couple with the inner surface of the collar; and
(b) a septum, wherein the septum has a lower surface, a side surface, and a tapered surface, wherein the side surface is substantially perpendicular to the lower surface, wherein the base of the port body engages the lower surface of the septum and the side surface of the septum, wherein the inner surface of the collar of the port body engages the tapered surface of the septum, wherein the septum is retained and compressed by the coupling of the collar and the base, and wherein said tapered surface of the septum is operably configured to engage said septum retainer such that multi-directional compression forces act upon said septum when housed within said septum retainer.

Abstract
A port, which may be used with a gastric banding assembly, having a septum therein that is subjected to multi-directional compression forces to aid in sealing imperfections caused by multiple needle sticks. Multi-directional compression forces, including axial compression and radial compression, may be created by providing a tapered septum. Such multi-directional compression forces may also be created by providing a tapered lead-in for inserting a septum into a port body.

6. A port comprising:
-
(a) a port body; (b) a septum retainer housed within said port body, wherein said septum retainer comprises a base and a collar, the collar having an upper annular rim, a lower annular rim, and an obliquely angled surface sloping from the upper annular rim to the lower annular rim, wherein the diameter of the upper annular rim is greater than the diameter of the lower annular rim, wherein the lower annular rim defines a plane, wherein the base includes an upwardly presented surface and an inwardly presented surface; and (c) a septum, wherein said septum comprises a lower surface, a side surface, and a substantially straight tapered surface, wherein the lower surface of the septum is disposed upon the upwardly presented surface of the base, wherein the side surface of the septum engages the inwardly presented surface of the base, wherein the side surface is substantially perpendicular to the lower surface of the septum, wherein at least a portion of the septum protrudes above the plane defined by the lower annular rim, wherein the collar engages the substantially straight tapered surface of the septum such that the septum is retained within said base and said collar when said septum retainer is assembled such that multi-directional compression forces act upon said septum. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A gastric banding assembly comprising:
-
(a) a gastric band; (b) an injection port, where the injection port is coupled to said gastric band with a delivery portion configured therebetween; (c) a septum retainer housed within said injection port, where said septum retainer comprises a base and a collar, wherein the collar has an inner surface extending about a circumference of the collar, wherein the inner surface of the collar is configured to have a substantially straight taper, wherein the base is configured to have a substantially straight taper that complements the substantially straight taper of the inner surface of the collar, wherein the base is configured to couple with the inner surface of the collar; and (d) a septum, wherein the septum has a lower surface, a side surface, and a tapered surface, wherein the side surface is substantially perpendicular to the lower surface, wherein the base is configured to engage both the lower surface of the septum and the side surface of the septum, wherein the inner surface of the collar engages the tapered surface of the septum, wherein the septum is retained and compressed by the coupling of the collar and the base such that multi-directional compression forces act upon said septum when housed within said septum retainer. - View Dependent Claims (16, 17, 18)
