Abstract
Abstract A method of making a nerve electrode is performed by forming an electrically insulative resilient array having an elongate backbone member with a plurality of spaced-apart substantially parallel bands, each spanning 360°, linked together by the backbone member and skewed from a direction normal to the backbone member; providing non-aligned single openings in the bands to render each of them incomplete with the remaining segments of each band linked by the backbone member and adapted to be spread apart to mount the array over the nerve and, when released, to resiliently close about the nerve; and securing an electrically conductive filament within at least one of the bands.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
95 words
A method of making a nerve electrode array, which comprises the steps of: forming an electrically insulative helix having a plurality of spiral bands, each spanning 360°, and a lengthwise member further linking the bands together, securing an electrically conductive filament in one of the bands for electrical connection to a lead wire at a site removed from the linking member, and severing each of the bands at a point away from the linking member whereby each band remains linked to the member and may be spread open for mounting the array about the nerve.
Claim 2
Independent Claim
95 words
A method of making a nerve electrode array, which comprises the steps of: forming an electrically insulative helix having a plurality of spiral bands, each spanning 360°, and a lengthwise member further linking the bands together, securing an electrically conductive filament in one of the bands for electrical connection to a lead wire at a site removed from the linking member, and severing each of the bands at a point away from the linking member whereby each band remains linked to the member and may be spread open for mounting the array about the nerve.
Claim 3
Dependent Claim
19 words
The method of claim 1, wherein: the electrically conductive filament is secured across the linking member in its band.
Claim 4
Dependent Claim
17 words
The method of claim 1, wherein: the bands are severed in non-aligned breaks lengthwise of the helix.
Claim 5
Dependent Claim
23 words
The method of claim 1, wherein: the bands are severed in a staggered array relative to the linking member, lengthwise of the helix.
Claim 6
Dependent Claim
24 words
The method of claim 1, including: electrically connecting a lead wire to the filament at said site and tethering the wire to a band.
Claim 7
Independent Claim
110 words
A method of making a nerve electrode, which comprises the steps of: forming an electrically insulative resilient array having an elongate backbone member with a plurality of spaced-apart substantially parallel loops, each spanning 360°, linked together by the backbone member and skewed from a direction normal to the backbone member; providing non-aligned single openings in the loops to render each of them incomplete with the remaining segments of each loop linked by the backbone member and adapted to be spread apart to mount the array over the nerve and, when released, to resiliently close about the nerve; and securing an electrically conductive filament within at least one of the loops.
Claim 8
Independent Claim
110 words
A method of making a nerve electrode, which comprises the steps of: forming an electrically insulative resilient array having an elongate backbone member with a plurality of spaced-apart substantially parallel loops, each spanning 360°, linked together by the backbone member and skewed from a direction normal to the backbone member; providing non-aligned single openings in the loops to render each of them incomplete with the remaining segments of each loop linked by the backbone member and adapted to be spread apart to mount the array over the nerve and, when released, to resiliently close about the nerve; and securing an electrically conductive filament within at least one of the loops.
Claim 9
Dependent Claim
18 words
The method of claim 6, wherein: the steps of forming and providing are performed in a single operation.
Claim 10
Dependent Claim
27 words
The method of claim 6, wherein: the step of providing openings in the loops is performed by severing each complete loop lengthwise relative to the backbone member.
Claim 11
Dependent Claim
23 words
The method of claim 6, wherein: the step of securing the electrically conductive filament is performed during the step of forming the array.
Claim 12
Dependent Claim
31 words
The method of claim 6, wherein: the step of securing the electrically conductive filament is performed to position the filament across the linking member without crossing the opening in its loop.
Claim 13
Dependent Claim
45 words
The method of claim 6, wherein: the step of providing openings in the loops is performed to place the opening in each loop at substantially the same location relative to the backbone member but skewed at an angle to the direction of the backbone member.
Claim 14
Dependent Claim
29 words
The method of claim 6, wherein: the step of providing openings in the loops is performed to produce staggered openings relative to the backbone member, lengthwise of the array.
Claim 15
Dependent Claim
28 words
The method of claim 6, further including: connecting an electrical lead to the filament at a point removed from the backbone member on the loop containing the filament.
Claim 16
Dependent Claim
21 words
The method of claim 13, further including: tethering the electrical lead to a loop removed from the loop containing the filament.
Claim 17
Dependent Claim
22 words
The method of claim 6, wherein: the step of forming the array is performed to produce spiral loops in a helical array.
Claim 18
Dependent Claim
23 words
The method of claim 6, wherein: the step of forming the array is performed to produce substantially planar loops in a helix-like array.
