ABSTRACT:
A method is provided for reconditioning a medication infusion pump by removal of accumulated medication deposits and the like to restore pump performance without requiring surgical removal of an implanted pump from a patient. The reconditioning process comprises sequential delivery of a buffer solution and a rinse solution to internal pump flow passages. The rinse solution is effective to dissolve medication deposits and the like within narrow pump flow passages before the rinse solution is neutralized by intermixing with the buffer solution. Dissolution of accumulated medication deposits results in restoration of pump performance substantially to original product specifications.
