Subdural electrode arrays for monitoring cortical electrical activity
First Claim
1. An electrode array for cranial implantation comprising:
- a plurality of electrode cables for detection of electrical activity in a patient'"'"'s body following implantation, anda bioresorbable material connected to the plurality of electrode cables, for maintaining thc cables in an initial predetermined spatial relationship and having a degradation period that corresponds with the period of intended use of the array to facilitate removal of the array.

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.

11. A electrode array for cranial implantation comprising:
-
at least one electrode cable having a branching structure for detection of electrical activity in a patient'"'"'s body following implantation, and a bioresorbable material connected to the branching structure of the electrode cable, for maintaining the cables in an initial predetermined spatial relationship and having a degradation period that corresponds with the period of intended use of the array to facilitate removal of the array, whereby after the bioresorbable material is reabsorbed, said at least one electrode cable may be withdrawn percutaneously. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
