Optionally pulsatile flow generating implantable pump

Abstract

An implantable pump configured to enable tuning of a delivery velocity of a fixed quantity of medicament. The implantable pump including a pump, an accumulator and a valve configured to enable tuning of a delivery velocity of a fixed quantity of medicament, wherein operating the pump with the valve continuously in the open state enables a steady-state delivery of medicament at a first velocity, and wherein closing of the valve enables the pump to at least partially fill the accumulator and subsequent opening of the valve enables the at least partially filled accumulator to dispense medicament, thereby delivering a bolus of medicament at a second velocity, wherein the second velocity is greater than the first velocity.
