Abstract:
A vascular access port having a plurality of distinct fluid reservoirs, said access port comprising:a. a needle-impenetrable base, said base comprising:i. a bottom wall;ii. an encircling sidewall upstanding from said bottom wall; andiii. an interior wall upstanding from said bottom wall and interconnecting a pair of nonadjacent locations on the interior of said encircling sidewall, thereby defining interior of said encircling sidewall a first fluid reservoir having a first inner floor and a second fluid reservoir on opposite sides of said interior wall having a second inner floor;b. a needle-impenetrable cap configured to receive said base therein, said cap comprising:i. a top wall;ii. an encircling skirt depending from said top wall;iii. a first access aperture formed through said top wall at a position that communicates with said first fluid reservoir, when said base is received in said cap; andiv. a second access aperture formed through said top wall at a position that communicates with said second fluid reservoir, when said base is received in said cap; andc. a needle-penetrable elastomeric compound septum comprising:i. a first target dome disposed in said first access aperture sealing said first access aperture, when said base is received in said cap with said compound septum disposed therebetween;ii. a second target dome disposed in said second access aperture sealing said second access aperture, when said base is received in said cap with said compound septum disposed therebetween; andiii. a septum web integrally formed with and interconnecting said first target dome and said second target dome, the side of said septum web opposite from said first target dome and said second target dome defining a lower side of said septum web, said septum web being so configured as to effect fluid isolation of said first fluid reservoir from said second fluid reservoir, when said base is received in said cap with said compound septum disposed therebetween.
