Abstract

In general, the invention is directed to an implantable medical device assembly having a more space-efficient housing and components, as well as processes for assembling the implantable medical device with reduced assembly cost and less complexity. The implantable medical device may incorporate a battery, capacitor, circuit assembly, feedthrough assembly, and interconnect assembly with respective electrical terminals. This configuration permits the use of automated electronic module assembly techniques such as parallel gap or ribbon bond welding to electrically connect the terminals. A feedthrough assembly may present a set of terminals adjacent a corresponding set of circuit terminals, also enabling the use of automated welding techniques.

Claims

26
AMENDED CLAIMS
[received by the International Bureau on 07 April 2003 (07.04.03); original claims 37 - 48 cancelled]
electrically coupling the feedthrough terminals to at least some of the circuit terminals via the flex circuit connector.
29. The method of claim 26, further comprising electrically coupling one or more conductive pins to the feedthrough terminals, wherein the pins extend from ύie feedthrough assembly and away from the housing.
30. The method of claim 26, wherein the feedthrough assembly includes an electrically insulative terminal block, multiple contact elements mounted within an interior side of the insulative terminal block to form the feedthrough terminals, and first channels formed in an exterior side of the terminal block for communication of conductive pins to the contact elements, and wherein the contact elements define second channels in communication with the first channels, the method further comprising threading the pins through the first, and second channels and fixing the pins in place to electrically couple the pins to the contact elements.
31. The method of claim 30, wherein fixing the pins in place includes welding the pins to the contact elements using an automated welding process.
32. The method of claim 30, further comprising welding the pins to the contact elements.
33. The method of claim 30, wherein the feedthrough assembly includes first and second feedthrough assemblies, each of the first and second feedthrough assemblies accommodating at least two of the conductive pins.
34. The method of claim 30, further comprising press-fitting the contact elements into the insulative terminal block.
35. The method of claim 26, wherein the interconnect assembly includes an antenna for radio frequency telemetry and an audible alarm device electrically coupled to the circuit terminals via the first set of interconnect terminals.
36. The metiiod of claim 26, further comprising: positioning the battery and the capacitor side by-side; positioning the circuit assembly over the battery; and positioning the interconnect assembly oveτ the circuit assembly and the capacitor.
