Claim 0:
1. A proto-device for implantation into soft tissue, the proto-device comprising:
an oblong device body, comprising a microelectrode comprising an electrically conductive core having a proximal end and a distal end, and at least one insulating layer on a portion of the core extending from the proximal end towards the distal end;
biodegradable irregularly intertwined microfibers adhesively and irregularly attached to the insulating layer and/or the core of the microelectrode, wherein each of the microfibers is biodegradable in the soft tissue within a period selected from the group consisting of one week, two weeks, one month and two months from the implantation of the proto-device; and
a rigid matrix of biocompatible material having an outer face and the rigid matrix enclosing the microelectrode and the microfibers with a portion of the microfibers dispersed in said rigid matrix; wherein the rigid matrix of biocompatible material is dissolvable and/or degradable in aqueous body fluid at a rate greater than the rate of microfiber degradation by a factor of at least 2 and up to a factor of about 100;
wherein the microelectrode has at least one means for supporting permanent positional stabilization of the microelectrode in the soft tissue upon biodegradation of the microfibers selected from the group consisting of a rugged surface of the device body, a knobby retainer comprising a rugged surface attached to the microelectrode, an eyelet, a loop or a bent section of the microelectrode, wherein the bent section is bent away from the central axis of the microelectrode by an angle of at least 15°.
