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.
Claims20
A port comprising:
- (a) a port body having a septum retainer therein;
- and
- (b) a septum, wherein said septum includes a tapered surface operably configured to engage said septum retainer such that multi-directional compression forces act upon said septum when housed within said septum retainer.
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;
- and
- (c) a septum, wherein said 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.
