ABSTRACT:
The present invention generally relates to an improved implantable medical device (IMD) and more particularly to an ultrasonically weld perforated lid for an IMD to form a hermetic seal between the IMD and the perforated lid. Appropriately configured perforated lids retain one or more components within a cavity or port formed in a part of an IMD. Such lids preferably secure a pierceable resilient grommet, septum or other resilient member in a cavity or port. When an adjustment instrument, a pull tool or a syringe is temporarily inserted therethrough and later extracted, the resilient member heals (i.e., seals and/or reseals). Preferably, the resilient member abuts a mechanical stop and is compressed slightly during assembly and ultrasonic welding of the lid. The resilient member preferably has a lateral dimension like the cavity or port so that when the lid compresses the resilient member it expands slightly and contacts the interior cavity surfaces thus improving the seal.
