Abstract
Abstract This proposal concerns a prosthesis, for a paraplegic with severed spinal cord, which operates by picking up motor signals from the still active nervous system and transmitting the same to stimulate spinal roots in the otherwise inactive part of the system, thereby bridging the lession. More particularly for this purpose, the invention proposes an implantable electrode connector device of flexible electrically insulating material having a base from which an array of leaves extend in a successive face-to-face array in the manner of a book, the leaves being resilient and tending to adopt a closed book configuration. In use of such a device, selected spinal roots are connected in the inter-leaf spaces with electrodes conveying appropriate motor signals.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
An implantable, electrode connector, prosthetic device of flexible, electrically insulating material comprising: an elongate base part, and a plurality of arrays of generally leaflike parts extending from said base part, each of said leaf-like parts being aligned in the longitudinal direction of said base part, the leaf-like parts of each array being disposed in a sequence extending traversely across said base part in successive face-to-face disposition in the manner of the pages of a book, said leaf-like parts being resilient and tending to adopt a closed book configuration for each array, and said arrays being disposed in mutually spaced sequence along said longitudinal direction.
Claim 2
Dependent Claim
104 words
An implantable, electrode connector, prosthetic device of flexible, electrically insulating material comprising: an elongate base part, and a plurality of arrays of generally leaflike parts extending from said base part, each of said leaf-like parts being aligned in the longitudinal direction of said base part, the leaf-like parts of each array being disposed in a sequence extending traversely across said base part in successive face-to-face disposition in the manner of the pages of a book, said leaf-like parts being resilient and tending to adopt a closed book configuration for each array, and said arrays being disposed in mutually spaced sequence along said longitudinal direction.
Claim 3
Dependent Claim
45 words
A device according to claim 1 wherein said leaf-like parts extend from one surface portion of said base part, and said base part is provided with respective bores leading from the opposite surface portion thereof into the spaces between adjacent ones of said leaf-like parts.
Claim 4
Dependent Claim
42 words
A device according to claim 1 wherein each of said leaf-like parts has a thickened peripheral portion remote from said base part to define with the remainder of the relevant part, an adjacent leaf-like part, and said base part, a tunnel-like cavity.
Claim 5
Dependent Claim
39 words
A device according to claim 1 wherein said base part is of strip form and each of said leaf-like parts is in the form of a substantially rectangular leaf extending from a common major surface of said base part.
Claim 6
Dependent Claim
21 words
A device according to claim 4 wherein each of said leaves has a thickened peripheral portion remote from said base part.
