An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. The method comprises registering a non-IMS enabled terminal with a Home IMS gateway, and, in response to said registration, performing an IMS registration on behalf of said terminal between the Home IMS gateway and the IMS using information obtained from an ISIM application present at the Home IMS gateway. The memory cell contains a charge storage layer and a first poly gate. The second valve assembly is operably dependent on the first valve assembly, thereby dynamically controlling the inflation profile of the airbag. In another embodiment, tensile stress in a silicon nitride film may be enhanced by depositing a silicon nitride film in the presence of a nitrogen-containing plasma at a temperature of less than about 400\xb0 C. The compounds of the formula bind to somatostatin receptors and are useful as pharmaceuticals.
