Endovascular Electrostimulation Near a Carotid Bifurcation in Treating Cerebrovascular Conditions

A system for treating a cerebrovascular condition in a living body comprising:

• i) an implantable elongated electrostimulation module comprising a proximal end and a distal end, said distal end comprising a branching point at which said distal end is branched into at least a first and a second distal end member;
• (ii) At least one metallic electrode mounted to each of said first and second distal end members;
• (iii) An electromagnetic transceiver disposed at said proximal end;
• (iv) at least one conductive galvanically distinct wire extending through said module and connecting said transceiver with each of said electrodes;
• and (v) An electrical signal generator for producing an electrical waveform to be coupled to said electrodes;
• said module being sized and shaped for transient endovascular positioning near a carotid body of said living body, said branching point being adjacent to the bifurcation of said carotid, said at least first and second distal end members being inserted to internal and external carotid arteries, thereby enabling the stimulation by said electrodes of chemoreceptors and optionally baroreceptors in said arteries adjacent to said bifurcation.
