Abstract
Implantable infusion apparatus includes a housing with an inlet passage extending into the housing at a pronounced promontory on the housing wall. The passage has an outer end at the top of the promontory and an inner end defined by a needle stop positioned inside the housing. Self-sealing septa mounted in the passage at selected spacings from the needle stop divide the passage into a plurality of aligned inlet ports each of which has its own fluid outlet. One of the outlets leads to a pumpable infusate reservoir having an outlet conduit connected to a catheter that extends outside the housing; another leads directly to the outlet conduit so that while a first fluid is being pumped from the reservoir to the catheter, a second fluid can be introduced into the other inlet port for mixing with the first fluid flowing to the catheter. Several different infusate flow configurations are also disclosed.
