ABSTRACT:
Electrodes arrays for monitoring in vivo electrical activity are disclosed. The arrays include a plurality of electrode contact pads in a predetermined spatial orientation held together by a structural matrix material that is preferably bioresorbable. The electrode pads are connected via lead wires to monitoring, analysis, and recording apparatus. The electrode arrays can be individually prepared, and configured (e.g., by irregular spacing between the electrode contact pads) to conform to the region undergoing analysis. Because the matrix material is substantially resorbed in the course of the protocol, the individual electrode cables will no long be attached to each other (or in the case of branching electrodes, the branches will no longer be fixed in position). In either instance, the electrode cables (or trunk and branches) can be removed without a second major operation.
