First Claim
Patent Images
1. An implantable device comprising:
- a header;
a housing;
one or more electrical connectors connected to the header and located externally relative to the housing; and
a feedthrough assembly mounted to the housing, the feedthrough assembly including a nonconductive base having one or more holes therethrough, the feedthrough assembly further including one or more feedthrough pins, each feedthrough pin extending through one of the one or more holes, each feedthrough pin including an integral structure including a pin body and an upper contact surface, wherein the upper contact surface is located externally of the housing for connecting to one or more of the electrical connectors, wherein the one or more feedthrough pins includes a nailhead shape with the upper contact surface having a larger connection surface area than a cross-sectional area of the pin body, wherein the pin body includes a lower pin body portion located internally and having a same diameter as a diameter as the rest of the pin body and smaller cross-sectional area than the upper contact surface.

12. An implantable device comprising:
-
a header; a housing; one or more electrical connectors connected to the header and located external relative to the housing, the one or more electrical connectors positioned in a predetermined configuration; and a feedthrough assembly mounted to the housing, the feedthrough assembly including a plurality of feedthrough pins, each feedthrough pin including an integral structure including a pin body and an upper contact surface, wherein the upper contact surface is located external of the housing for connecting to one or more of the electrical connectors, wherein the one or more feedthrough pins includes a nailhead shape with the upper contact surface having a larger connection surface area than a cross-sectional area of the pin body, wherein the plurality of feedthrough pins are positioned in a configuration to substantially match the configuration of the one or more electrical connectors, and wherein the pin body includes a lower pin body portion located internally and having a same diameter as a diameter as the rest of the pin body and smaller cross-sectional area than the upper contact surface. - View Dependent Claims (13, 14, 15, 16)

17. A method comprising:
-
assembling a header subassembly for an implantable device such that a plurality of connectors extend from the header in a predetermined configuration; placing the header subassembly onto a housing such that the connectors are on or above upper surfaces of feedthrough pins attached to the housing, wherein each of the feedthrough pins includes an integral structure including a pin body and an upper contact surface, wherein the upper contact surface is located external of the housing and wherein the upper contact surfaces of the feedthrough pins including a nailhead shape having a larger connection surface area than a cross-sectional area of the pin body, and wherein the pin body includes a lower pin body portion located internally and having a same diameter as a diameter as the rest of the pin body and smaller cross-sectional area than the upper contact surface; and connecting the connectors to the feedthrough pins. - View Dependent Claims (18, 19, 20)
