A hydraulic basal chamber (314) has a portion of the outer wall (226a) proximate the attachment surface and having a second thermal conductance. The second thermal conductance is greater than the first thermal conductance. A flow restrictor is fluidly coupling the hydraulic basal chamber and the hydraulic pump chamber. A fluid reservoir is coupled to the hydraulic pump chamber. The fluid reservoir is configured to contain a fluid deliverable to a patient. An actuator is coupled to the hydraulic basal chamber. The actuator is configured to pressurize the hydraulic pump chamber to transfer energy through the hydraulic basal chamber and the hydraulic pump chamber to the fluid reservoir to deliver the fluid at a sustained basal rate.
