Method and apparatus for communicating with a sealed electronic device via the electronic device’s existing data ports for programming, testing configuration or diagnosis of the electronic device such as a transmitter unit for use in a data monitoring and management system such as analyte monitoring and management system is provided. The female connector includes a first insulator and a number of female terminals. In an alternative embodiment, the catheter shaft further comprises a sleeve in the inflation lumen that secures a distal section of the support mandrel. In another embodiment, the propellant pillow includes a propellant bag having a surrounding layer of resealable material encompassing the bag. The distal end of each running board member has a groove that acts as a vacuum release allowing the board to run smoother freeing the board from drag resistance for better performance. The brush housing is electrically charged to the same electrical potential as said transfer roller and is selectively discharged.
