An aneurysmal sac arterial wall electrostimulation system ( 11 ) comprises an array of electrical leads ( 4 and 5 ) placeable in contact with a portion of the arterial wall ( 12 ) to be electrostimulated and a source ( 3 ) of electrostimulation attached to the array of electrical leads. The source provides periodic electrostimulus to at least one of the array of leads in accordance with a treatment program and at least one of the array of leads senses the contraction condition of the aneurysmal sac arterial wall ( 10 ) which is provided as a feedback loop input signal to the treatment program. Repeated electrostimulation of a vascular passage using the system ( 11 ) provides increased muscle tone or pseudo permanent contraction of such vascular passage.
