Electrolytic capacitor for use in an implantable medical device

A capacitor structure for use in an implantable medical device, said capacitor structure comprising:

• a shallow-drawn encasement having first and second major sides and a peripheral wall coupled to said first and second major sides;
• a cathode disposed within said encasement proximate said first and second major sides, said cathode having a cathode lead;
• a centrally disposed anode within said encasement, said anode having an anode lead;
• and
• a bipolar polymeric feedthrough in said encasement through which electrical coupling may be made to said anode lead and said cathode lead, said feedthrough comprising:
• a ferrule coupled through said encasement;
• and
• a wire guide having first and second apertures therethrough positioned within said ferrule.
