Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
In an implantable electrode system of the type adapted to provide electrical coupling to a nerve bundle and including an electrode element with an electrical lead wire connected to the electrode element and adapted to be connected to remote medical instruments, a lead wire tether comprising: a flexible carrier element adapted for attachment to the nerve bundle; and a lead wire retaining ring, attached to said carrier element and adapted to surround a portion of the electrical lead wire, wherein said carrier element comprises a helically shaped body adapted to surround a portion of the nerve bundle.
Claim 2
Dependent Claim
97 words
In an implantable electrode system of the type adapted to provide electrical coupling to a nerve bundle and including an electrode element with an electrical lead wire connected to the electrode element and adapted to be connected to remote medical instruments, a lead wire tether comprising: a flexible carrier element adapted for attachment to the nerve bundle; and a lead wire retaining ring, attached to said carrier element and adapted to surround a portion of the electrical lead wire, wherein said carrier element comprises a helically shaped body adapted to surround a portion of the nerve bundle.
Claim 3
Dependent Claim
120 words
A surgically implantable electrode system for providing electrical coupling to a nerve bundle, said system comprising: (a) an electrode including: an insulating element adapted to be positioned around a portion of the nerve bundle, a conductor element mounted with said insulating element, said conductor element being adapted for electrical coupling to the nerve bundle, and an electrical lead element coupled to said conductor element; and (b) an electrode lead wire tether means for tethering said electrical lead element to the nerve bundle, said tether means comprising a flexible carrier element adapted to surround a portion of the nerve bundle and a lead wire retaining ring attached to said carrier element, and adapted to receive and retain said electrical lead element.
Claim 4
Dependent Claim
120 words
A surgically implantable electrode system for providing electrical coupling to a nerve bundle, said system comprising: (a) an electrode including: an insulating element adapted to be positioned around a portion of the nerve bundle, a conductor element mounted with said insulating element, said conductor element being adapted for electrical coupling to the nerve bundle, and an electrical lead element coupled to said conductor element; and (b) an electrode lead wire tether means for tethering said electrical lead element to the nerve bundle, said tether means comprising a flexible carrier element adapted to surround a portion of the nerve bundle and a lead wire retaining ring attached to said carrier element, and adapted to receive and retain said electrical lead element.
Claim 5
Dependent Claim
15 words
The system of claim 2, wherein said flexible carrier element is formed of silicone rubber.
Claim 6
Dependent Claim
16 words
The system of claim 2, wherein said lead wire retaining ring is formed of silicone rubber.
Claim 7
Dependent Claim
25 words
The system of claim 2, wherein said flexible carrier element comprises a helically shaped element adapted for mounting around a portion of the nerve bundle.
Claim 8
Dependent Claim
25 words
The system of claim 2, wherein said flexible carrier element comprises a spirally shaped element adapted for mounting around a portion of the nerve bundle.
