INTEGRATED BACKUP BAND FOR USE IN FORMING AN ENCLOSURE FOR A MEDICAL DEVICE
First Claim
1. A method of assembling an implantable medical device, the method comprising:
- placing a backup band in a first half-enclosure having a surface and a sidewall extending from the surface, the backup band having a sidewall and comprising an edge, the backup band placed in the first half-enclosure so that a portion of the sidewall of the backup band comprising the edge extends beyond an edge of the sidewall of the first half-enclosure;
placing a thermoform in the first half-enclosure, the thermoform having a surface and a sidewall extending from the surface, wherein the thermoform is placed so that the sidewall of the backup band is between the sidewall of the first half-enclosure and the sidewall of the thermoform;
securing the thermoform to the first half-enclosure;
placing a second half-enclosure relative to the first half-enclosure, the second half-enclosure having a surface and a sidewall extending from the surface, the first half-enclosure and the second half-enclosure placed relative to each other so that the sidewall of the second half-enclosure is adjacent to and surrounds the portion of the backup band that extends beyond the edge of the sidewall of the first half-enclosure, and the edge of the first half-enclosure and the edge of the second half-enclosure align with and abut each other to form a seam; and
welding the seam to create a hermetic seal.

Abstract
An implantable medical device includes an enclosure having a sidewall and a welded seam in the sidewall, the seam extends along a perimeter of the enclosure. A thermoform is located adjacent a surface of the enclosure and is secured in place within the enclosure. A metalized surface is located adjacent an interior surface of the enclosure sidewall and is secured in place by the thermoform. The metalized surface extends along a perimeter of the enclosure and is configured to obstruct laser energy during a weld seam process. The metalized surface may be provided as a separate backup band component or may be integrated in a perimeter sidewall of the thermoform.
