An implantable pump system includes: an implantable pump having separate chambers or reservoirs; and a catheter having two or more reservoir-specific inlet ports directed into respective lumens of the catheter. In one embodiment, the distal tips of the respective lumens may be directed to different sites within the patient's body, thereby allowing site specific and independent delivery of the medications stored in the respective pump chambers or reservoirs to be administered to different body sites at independently controlled times and rates. In another embodiment, the distal tips of the respective lumens are directed, more or less, to the same body site or tissue region, thereby providing for the independent delivery of multiple medications to the same regions at independently controlled times and rates. |
