Abstract

Abstract An improved body implantable electrical stimulator assembly of the type having interconnected electrical components housed within a preformed enclosure. A cup is provided in which the components are finally assembled, the cup being configured to fit within the enclosure. Preferably, the enclosure is formed of a plurality of members at least one of which has a main wall and a side wall joined at a radius. The cup is similarly formed of a main wall and a side wall, the main wall being generally coextensive with at least a major portion of the enclosure member main wall. The cup engages the enclosure in a manner such that its movement within the enclosure is limited. Movement of the components within the cup is restrained.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 107 words
In a body implantable electrical stimulator of the type having interconnected electrical components housed within a preformed enclosure, the enclosure having a plurality of members at least one of which has a main wall and a side wall joined at a radius, the improvement which comprises cup means formed of a main wall and a side wall, said cup main wall being generally coextensive with at least a major portion of said enclosure member main wall and said cup means side wall encircling said components, said cup means further comprising means engaging said enclosure member radius for mechanically limiting movement of said cup means within said enclosure.
Claim 2
Dependent Claim 107 words
In a body implantable electrical stimulator of the type having interconnected electrical components housed within a preformed enclosure, the enclosure having a plurality of members at least one of which has a main wall and a side wall joined at a radius, the improvement which comprises cup means formed of a main wall and a side wall, said cup main wall being generally coextensive with at least a major portion of said enclosure member main wall and said cup means side wall encircling said components, said cup means further comprising means engaging said enclosure member radius for mechanically limiting movement of said cup means within said enclosure.
Claim 3
Dependent Claim 24 words
The body implantable stimulator of claim 1 wherein said radius engaging means comprises a plurality of extending members resiliently engaging said enclosure member radius.
Claim 4
Dependent Claim 34 words
The body implantable stimulator of claim 1 wherein said radius engaging means comprises radius means joining said cup means main and side walls and resiliently urged into engagement with said enclosure member side walls.
Claim 5
Dependent Claim 20 words
The body implantable stimulator of claim 1 further comprising means for maintaining said components in position within said cup means.
Claim 6
Dependent Claim 22 words
The body implantable stimulator of claim 4 wherein said component position maintaining means comprises an encapsulating material substantially filling said cup means.
Claim 7
Dependent Claim 23 words
The body implantable stimulator of claim 4 wherein said component position maintaining means comprises tab means engaging at least some of said components.
Claim 8
Dependent Claim 64 words
The body implantable stimulator of claim 4 wherein the inner surface of said cup means is provided with at least one recess configured to accept one of said components, said component position maintaining means comprising means unitary with said cup means resiliently engaging said one component to maintain it within a recess while allowing for differences in size in the component within said recess.
Claim 9
Dependent Claim 22 words
The body implantable stimulator of claim 1 wherein said cup means further comprises a side wall provided with antenna coil form means.
Claim 10
Dependent Claim 28 words
The body implantable stimulator of claim 8 wherein said antenna coil form means lies generally within a plane which is skewed relative to said cup means main wall.
Claim 11
Dependent Claim 76 words
In a body implantable electrical stimulator of the type having interconnected electrical components housed within a preformed enclosure, the improvement which comprises cup means configured to fit within said enclosure and having a main wall and a side wall, said side wall being provided with an antenna coil form which lies generally within a plane which is skewed relative to said main wall so as to increase the sensitivity of an antenna within said coil form.
Claim 12
Dependent Claim 76 words
In a body implantable electrical stimulator of the type having interconnected electrical components housed within a preformed enclosure, the improvement which comprises cup means configured to fit within said enclosure and having a main wall and a side wall, said side wall being provided with an antenna coil form which lies generally within a plane which is skewed relative to said main wall so as to increase the sensitivity of an antenna within said coil form.
