Implantable access port

摘要

An implantable access port is capable of being implanted beneath the skin of a patient, the access port enabling repeated, non-destructive fluid communication between a needle piercing the skin of the patient and the proximal end of a selected one of the lumens of a dual lumen catheter, said access port comprising: (a) a needle-impenetrable base having a flat floor and walls normal to and upstanding therefrom, said walls defining a first fluid cavity and a second fluid cavity; (b) a septum support configured to mate with the free ends of said walls of said base opposite from said floor thereof, said septum support having formed therethrough a first septum receiving aperture positioned opposite said first fluid cavity when said septum support mates with said free ends of said walls of said base an a second septum receiving aperture positioned opposite said second fluid cavity when said septum support mates with said free ends of said walls of said base; and (c) a needle-impenetrable cap configures to receive said septum support and said base, said cap comprising a top wall having formed therein: (i) a first septum access aperture communicating through said top wall of said cap at a position opposite said first septum receiving aperture when said septum support is received in said cap, said first septum access aperture and said first septum receiving aperture together defining a first access aperture communicating with said first fluid cavity; and (ii) a second septum access aperture communicating through said top wall of said cap at a position opposite said second septum receiving aperture when said septum support is received in said cap, said second septum access aperture and said second septum receiving aperture together defining a second access aperture communicating with said second fluid cavity; (d) a first needle-penetrable septum captured between said septum support and said cap sealing said first access aperture; and (e) a second needle-penetrable septum captured between said septum support and said cap sealing said second access aperture. <IMAGE>
