Abstract
Abstract An electrode support structure has at least two spline leaves, each comprising an opposed pair of spline elements connected by a center web. Each web has a hole through which a pin assembly extends to join the webs of the spline leaves in a mutually stacked relationship. The spline elements radiate from the pin assembly in a circumferentially spaced relationship for carrying one or more electrodes. A hub member is over-molded about the pin assembly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
An electrode support structure comprising at least two spline leaves, each spline leaf being formed of a single aenerally flat sheet of material and comprising an opposed pair of spline elements connected by a center web, each spline element having a terminal end spaced from the web, each web including a hole through the thickness of the web generally equidistant from the terminal ends -of the respective spline leaf, a pin assembly extending through the holes of each of said webs to thereby join the webs of the spline leaves in a mutually stacked relationship with the spline elements radiating from the pin assembly in a circumferentially spaced relationship, said spline elements each having one or more electrodes mounted thereon, and a hub member over-molded about the pin assembly. said hub member having a central axis, each of said sDline elements extending generally perpendicularly from the axis of said hub.
Claim 2
Dependent Claim

An electrode support structure comprising at least two spline leaves, each spline leaf being formed of a single aenerally flat sheet of material and comprising an opposed pair of spline elements connected by a center web, each spline element having a terminal end spaced from the web, each web including a hole through the thickness of the web generally equidistant from the terminal ends -of the respective spline leaf, a pin assembly extending through the holes of each of said webs to thereby join the webs of the spline leaves in a mutually stacked relationship with the spline elements radiating from the pin assembly in a circumferentially spaced relationship, said spline elements each having one or more electrodes mounted thereon, and a hub member over-molded about the pin assembly. said hub member having a central axis, each of said sDline elements extending generally perpendicularly from the axis of said hub.
Claim 3
Dependent Claim
55 words
A support structure according to claim 1 wherein the spline elements flex relative to the center web, and further including a base member joined to the terminal ends of each of the spline elements at a fixed distance from said Din assembly sufficient to cause said spline elements to flex into a three dimensional shape.
Claim 4
Dependent Claim
18 words
