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.

A transducer apparatus is disclosed having a spool member with a body portion and first and second elevated regions formed on the body portion. A PVDF film surrounds the spool member, the film including an inner surface facing the spool member and an outer surface opposite the inner surface. The film as surrounding the spool member has a predetermined frequency of resonance. Lateral ends of the film are secured together by a securing material. The securing material is such that the secured ends of the film will have substantially the same resonance frequency as a remainder of the film. The film includes a non-electrode area at a perimeter of the inner surface and an electrode material formed on a remainder of the inner surface. Upon securing the lateral edges of the film together, the securement is at overlapping non-electrode lateral edges of the film. The securing material may be any one of an adhesive in combination with screws or thermally deformable nails, adhesive alone, tape, or ultrasonic welding.
