Abstract In various embodiments, a drug pump includes a housing and, within the housing, an expandable drug reservoir at least part of which is exposed to a pressurized propellant. The propellant exerts a substantially constant pressure on the drug reservoir. A flow restrictor significantly limits outflow from the pump, and preferably has both a small diameter and a long path length, which acts to control the outflow from the drug reservoir. As a result, the pump produces a substantially constant outflow. Dans divers modes de réalisation, une pompe à médicament comprend un corps et, à l'intérieur du corps, un réservoir de médicament expansible dont au moins une partie est exposée à un agent propulseur sous pression. L'agent propulseur exerce une pression sensiblement constante sur le réservoir de médicament. Un limiteur de débit limite de manière significative l'écoulement sortant de la pompe, et a de préférence à la fois un petit diamètre et une longueur de trajet longue, qui agit pour commander l'écoulement sortant du réservoir de médicament. Par conséquent, la pompe produit un débit sensiblement constant.
