1. A system for performing any one of hemodialysis, hemodiafiltration, hemofiltration, comprising:
- a controlled compliant flow path comprising a dialyzer;
a single control pump in fluid communication with the controlled compliant flow path the control pump for selectively metering in and metering out fluid from the controlled compliant flow path; and
a common reservoir in fluid communication with the control pump, wherein the control pump is a bidirectional pump, wherein the common reservoir contains any one of a dialysate, a filtrate, a volume of a physiologically compatible priming solution, a volume of a physiologically compatible solution to provide a bolus of fluid to a subject receiving treatment, a volume of physiologically compatible solution to provide solution for return of blood from an extracorporeal flow path to a subject receiving treatment, a volume of solution returned to the common reservoir from an extracorporeal flow path when blood from a subject is introduced to the extracorporeal flow path, and combinations thereof.

Abstract
Systems and methods for controlling fluid movement and volumes of fluid between a subject and a controlled compliant flow path. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the controlled compliant flow path. An extracorporeal flow path is in fluid communication with the controlled compliant flow path across a semi-permeable membrane where the extracorporeal flow path has a first terminal end and a second terminal end.
