Abstract

A pump for delivering a fluid includes a pump housing that defines at least one reservoir having a circumferentially open first end, a circumferentially closed second end and a chamber to receive the fluid. The pump includes a plunger assembly having at least one plunger arm and a cannula fluidly coupled to the plunger arm to dispense the fluid from the pump. The plunger arm is receivable within the first end of the reservoir, and the at least one plunger arm defining an internal conduit to receive the fluid from the at least one fluid reservoir. The internal conduit is fluidly coupled to the cannula. The plunger assembly is movable in a first direction relative to the pump housing to advance the plunger arm within the fluid reservoir to dispense the fluid from the fluid reservoir out of the pump via the cannula.
