## Abstract

A treatment delivery system includes a fluid delivery system connected to a first fluid reservoir and a second fluid reservoir. The system directs a first fluid from the first fluid reservoir to a treatment site and directs a second fluid from the second fluid reservoir to the treatment site and a control unit to control the fluid delivery system according to a treatment process comprising a flow of the first fluid and the second fluid, the treatment process including multiple phases. A first phase includes a controlled delivery of the first fluid from the first fluid reservoir to the treatment site. A second phase of the plurality of phases includes a controlled delivery of the second fluid from the second fluid reservoir to the treatment site, the control unit automatically activating a transition from at least the first phase to the second phase.
