Abstract

An apparatus for treatment of a medical condition of a patient to provide drainage from a region of a patient to a drainage location includes a memory having a plurality of different selectable treatment algorithms stored therein for treating a medical condition, and may include a processor associated with the memory and configured to execute one of the different treatment algorithms. It also may include a flow system controllable by the processor to regulate drainage of fluid from a body portion having a medical condition, the flow system being controllable according to a selected algorithm of said different selectable treatment algorithms. In one aspect, the apparatus further comprises an implantable medical device for treating an ocular condition, and the processor is carried on the implantable medical device.
