Programmable implantable pump with accessory reservoirs and multiple independent lumen catheter
First Claim
1. An implantable medication delivery apparatus for use with an external controller, the apparatus comprising:
- a single implantable housing;
a plurality of medication-storage chambers within the single implantable housing;
a pump apparatus within the single implantable housing and operably connected to the plurality of medication-storage chambers;
a plurality of lumens in fluid communication with a respective one of the plurality of medication-storage chambers; and
a controller, within the single implantable housing and operably connected to the pump apparatus, configured to control the pump apparatus to pump medication from one of the medication-storage chambers at a predetermined basal rate and to control the pump apparatus to pump a bolus of medication from another one of the medication-storage chambers in response to a bolus delivery signal from the external controller.

Abstract
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.
