Multi-channel structurally robust brain probe and method of making the same
First Claim

1. A bio-probe having a base and a tip, and comprising:
- (a) a core of substantially rigid, high-strength material, said core being substantially circular in cross-section, and tape ring inwardly from said base to said tip, said tapering being substantially uniform in cross-section so that said tip of said core has substantially the same cross-sectional shape as said base of said core, but is of a smaller cross-sectional size;
(b) a set of conductors extending longitudinally from said base to a position near to said tip and collectively substantially circumscribing said core;
(c) dielectric material, substantially electrically isolating each said conductor from its surroundings; and
(d) a set of apertures through said dielectric material to said set of conductors, hereby defining a set of electrodes.

Abstract
A bio-probe having a base and a tip, and comprising a core of substantially rigid, high-strength material, said core tapering inwardly from the base to the tip and a set of conductors extending longitudinally about said core. In addition, dielectric material, substantially electrically isolates each conductor from its surroundings. Also, a set of apertures is defined by the dielectric material to the set of conductors, thereby defining a set of electrodes.
