Abstract
Abstract The invention provides an electrode suitable for biological implantation comprising support means and at least one electrode mounted on the support means which support means includes one or more discontinuities in the structure, shape or material of the support means positioned near one end of the support means to facilitate deflection of that end of said support means on encounting an obstacle during the implantation procedure. The invention provides an electrode array for prosthetic implantation, comprising a biologically inert support member having an inner end and an outer end, a plurality of electrodes supported by said support member at predetermined space distances along a portion of the length of said support member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
69 words
An electrode suitable for electrode suitable for biological implantation comprising support means and at least one electrode mounted on the support means, characterized in that said support means includes one or more discontinuities in the structure, shape or material of the support means positioned near one end of the support means to facilitate deflection of that end of said support means on encounting an obstacle during the implantation procedure.
Claim 2
Dependent Claim
69 words
An electrode suitable for electrode suitable for biological implantation comprising support means and at least one electrode mounted on the support means, characterized in that said support means includes one or more discontinuities in the structure, shape or material of the support means positioned near one end of the support means to facilitate deflection of that end of said support means on encounting an obstacle during the implantation procedure.
Claim 3
Dependent Claim
98 words
An electrode array for prosthetic implantation, comprising a biologically inert support member having an inner end and an outer end, a plurality of electrodes supported by said support member at predetermined space distances along a portion of the length of said support member, conducting wires associated with each electrode and passing through the outer end of said support member, and at least one discontinuity in the structure, shape or material of said support member, said discontinuity being positioned such that the inner end of said support member may be deflected on encountering an obstacle during the implantation procedure.
Claim 4
Dependent Claim
98 words
An electrode array for prosthetic implantation, comprising a biologically inert support member having an inner end and an outer end, a plurality of electrodes supported by said support member at predetermined space distances along a portion of the length of said support member, conducting wires associated with each electrode and passing through the outer end of said support member, and at least one discontinuity in the structure, shape or material of said support member, said discontinuity being positioned such that the inner end of said support member may be deflected on encountering an obstacle during the implantation procedure.
Claim 5
Dependent Claim
23 words
The electrode array of claim 2, wherein said discontinuity is positioned within the first one third of the length of said support member.
Claim 6
Dependent Claim
35 words
The electrode array of claim 3, wherein said support member is about 25mm long, said discontinuity in a portion of the inner end of the support member which is about eight to ten mm long.
Claim 7
Dependent Claim
23 words
The array of claim 1 , 2 or 3, wherein said discontinuity comprises a neck formed in the surface of said support member.
Claim 8
Dependent Claim
25 words
The array of claim 1, 2 or 2, wherein said discontinunity comprises an element of material more flexible than the material of said support member.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
39 words
The electrode array of claim 4, wherein said discontinuity comprises a neck formed in the surface of said member and comprises an element of material more flexible than the material of the support member approximately 0.1 to 0.5mm wide.
Claim 11
Dependent Claim
18 words
The electrode array of claim 6, wherien said element is nicked to a depth of 0.002 to 0.1mm.
