Programmable implantable pump with accessory reservoirs and multiple independent lumen catheter
First Claim
1. An implantable pump system comprising:
- an implantable pump comprising a single implantable housing wherein multiple separate chambers are housed, each of which is filled with a prescribed medication, and pump means coupled to each chamber for delivering a programmable rate of delivery of the medication stored in the respective chamber;
a patient controller that enables the actuation of the pump means so as to administer a bolus or programmed rate of the medication contained in the respective chamber coupled to the pump means; and
a multi-lumen catheter having respective lumens, each lumen of which is connected to one of the respective chambers within the implantable pump housing, and wherein each lumen terminates at a distal tip through which medication contained within the respective chamber may be dispensed under control of the pump means.

Abstract
An implantable pump system includes: (1) an implantable pump having separate chambers or reservoirs, at least one of which is coupled to the pump so as to allow a programmable rate of delivery of the medication stored in the pump chamber or reservoir, the other chambers or reservoirs of which are at least capable of delivery of a bolus via a pressurized, and potentially independently programmable chamber or pumping mechanism; (2) a patient controller that enables the actuation of the pump so as to administer a bolus or programmed rate of the first, second, third, . . . or nth medication contained in the independent chambers or reservoirs coupled to the pump; and (3) 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.

11. An implantable pump system comprising:
-
implantable pump means for dispensing medication, said pump means being housed within a single implantable housing;
a plurality of separate medication-storage chambers within the single implantable housing and coupled to the pump means;
a catheter having a plurality of independent lumens, wherein each lumen is in fluid communication with a respective one of the plurality of separate medication-storage chambers; and
implantable control means within the single implantable housing and coupled with the pump means for controlling the pump means so that a programmable rate of delivery of medication may be dispensed through each of the plurality of lumens within the catheter. - View Dependent Claims (12, 13, 14, 15)
