Method and apparatus for treating aneurysms by electrostimulation
First Claim
1. An aneurysmal sac arterial wall electrostimulation system, comprising:
- an array of electrical leads placeable in contact with a portion of the arterial wall to be electrostimulated; and
a source of electrostimulation attached to said array of electrical leads, wherein said source provides periodic electrostimulus to at least one of the array of leads in accordance with a treatment program and wherein at least one of the array of leads senses the contraction condition of the aneurysmal sac arterial wall which is provided as a feedback loop input signal to said treatment program.

Abstract
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.

7. A method for providing electrostimulation to an aneurysmal sac arterial wall, comprising the steps of:
-
implanting leads to provide stimulation inducing the contraction of the aneurysmal sac arterial wall;
electrically stimulating said leads according to a treatment program;
sensing a contraction condition of the aneurysmal sac; and
adjusting the treatment program based on the information received from the step of sensing the contraction condition. - View Dependent Claims (8, 9, 10, 11)
