Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
An implantable medical device, comprising: a first enclosure portion having a generally planar first, lower interior surface, a second interior surface generally parallel to said first, lower interior surface and displaced upward from said first, lower interior surface and a circumferential edge surface; adhesive, located on said first, lower interior surface; a battery having a terminal, said battery located on said adhesive; an electronic circuit having a bonding pad, said electronic circuit located on said adhesive; a wire, coupling said terminal to said bonding pad and wire bonded to said terminal and said pad; a feedthrough, mounted to said first enclosure portion, extending through said second interior surface and extending from an exterior surface of said first enclosure portion; a second enclosure portion mounted to said first enclosure portion to enclose said battery and circuit.
Claim 2
Dependent Claim
135 words
An implantable medical device, comprising: a first enclosure portion having a generally planar first, lower interior surface, a second interior surface generally parallel to said first, lower interior surface and displaced upward from said first, lower interior surface and a circumferential edge surface; adhesive, located on said first, lower interior surface; a battery having a terminal, said battery located on said adhesive; an electronic circuit having a bonding pad, said electronic circuit located on said adhesive; a wire, coupling said terminal to said bonding pad and wire bonded to said terminal and said pad; a feedthrough, mounted to said first enclosure portion, extending through said second interior surface and extending from an exterior surface of said first enclosure portion; a second enclosure portion mounted to said first enclosure portion to enclose said battery and circuit.
Claim 3
Dependent Claim
134 words
An implantable medical device, comprising: a first enclosure portion having a generally planar first, lower interior surface, a second interior surface generally parallel to said first, lower interior surface and displaced upward from said first, lower interior surface and a circumferential edge surface; a battery, mounted to said first, lower interior surface; an electronic circuit, coupled to said battery and having a bonding pad, said electronic circuit mounted to said first, lower interior surface; a feedthrough, mounted to said first enclosure portion, extending through said second interior surface and extending from an exterior surface of said first enclosure portion; a wire, coupling said terminal to said bonding pad and wire bonded to said feedthrough and said bonding pad; a second enclosure portion mounted to said first enclosure portion to enclose said battery and circuit.
Claim 4
Dependent Claim
134 words
An implantable medical device, comprising: a first enclosure portion having a generally planar first, lower interior surface, a second interior surface generally parallel to said first, lower interior surface and displaced upward from said first, lower interior surface and a circumferential edge surface; a battery, mounted to said first, lower interior surface; an electronic circuit, coupled to said battery and having a bonding pad, said electronic circuit mounted to said first, lower interior surface; a feedthrough, mounted to said first enclosure portion, extending through said second interior surface and extending from an exterior surface of said first enclosure portion; a wire, coupling said terminal to said bonding pad and wire bonded to said feedthrough and said bonding pad; a second enclosure portion mounted to said first enclosure portion to enclose said battery and circuit.
Claim 5
Dependent Claim
52 words
An implantable device according to claim 1 or claim 2, further comprising a connector module, mounted to said circumferential edge surface, a conductor coupling said feedthrough to said connector module and an insulative coating covering said conductor and a portion of said exterior surface of said first enclosure portion proximate said feedthrough.
Claim 6
Dependent Claim
31 words
An implantable device according to claim 1 or claim 2, wherein said feedthrough comprises a feedthrough pin having an expanded portion defining a bonding pad parallel to said second interior surface.
