Implantable dual reservoir access port

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.
