Ultrasonically welded, staked or swaged components in an implantable medical device

An implantable medical device, comprising:

• (a) a part or component;
• (b) a pre-formed header or connector module having an outer surface and formed of a thermoplastic material, the module having a recess disposed therewithin, the recess being defined by an inner surface and an outer periphery contiguous with the outer surface, the outer periphery being propinquant to or contiguous with a first mating surface disposed near or in the recess, at least portions of the recess being configured to receive the part or component therewithin;
• (c) an hermetically sealed enclosure attached to the module, and
• (d) a cover or lid having a second mating surface for engaging the first mating surface, the cover or lid being formed of thermoplastic material, the second mating surface of the cover or lid being aligned with and matingly engaging at least portions of the first mating surface of the recess, the cover covering the recess and being ultrasonically welded to the connector or header module such that melted thermoplastic material resides in or near the region of the first and second mating surfaces.

An implantable medical device, comprising:

• (a) means for forming a part or component;
• (b) means for forming a pre-formed header or connector module having an outer surface and formed of a thermoplastic material, the module forming means having means for forming a recess disposed therewithin, the recess forming means being defined by an inner surface and an outer periphery contiguous with the outer surface, the outer periphery being propinquant to or contiguous with a first means for mating near or in the recess, at least portions of the recess forming being configured to receive the part or component forming means therewithin;
• (c) means for forming an hermetically sealed enclosure attached to the module forming means, and
• (d) means for forming a cover or lid having a second means for mating and engaging the first mating means, the cover or lid forming means being formed of thermoplastic material, the second mating means of the cover or lid forming means being aligned with and matingly engaging at least portions of the first mating means of the recess forming means, the cover forming means covering the recess forming means and being ultrasonically welded to the connector or header module forming means such that melted thermoplastic material resides in or near the region of the first and second mating means.
