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;
a treatment program for controlling said aneurysmal sac arterial wall electrostimulation stored in a memory of said system; 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 said 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 in a matter so as to provide a controlled arterial wall contraction to offset arterial blood pressure.

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)
