The present invention relates to phosphatase polypeptides, nucleotide sequences encoding the phosphatase polypeptides, as well as various products and methods useful for the diagnosis and treatment of various phosphatase-related diseases and conditions. Negative and positive lift effects and aerodynamic drag effects are obtained by adjusting pivotable rear part between an upwardly pivoted position and a downwardly pivoted position. The delay element includes micro-miniature path changing mirrors controlled in path length selecting positioning by input signals of logic level magnitude. A stabilization balloon may be used to axially and radially locate the deployment mechanism relative to the site of implantation.
