ABSTRACT:
A multiple reservoir or chambered implantable pumps is disclosed. The pump according to the present invention is particularly useful in allowing for multiple constant flow rates to be provided from an otherwise constant flow implantable pump. The pump is also useful in allowing for housing of multiple active substances. A multiple reservoir implantable pump is also disclosed, which has at least one chamber capable of providing a constant flow rate and at least one chamber capable of being utilized for patient controlled injections.
