An intravascular filter includes at least one elongated support member configured to assume a retention configuration, such as a generally helical form about a central axis, and at least one flexible elongated filter member supported by the support member. The pressure of each individual support cylinder may be automatically adjustable by changing the tension on a spring, or by modifying the internal air pressure of a pneumatic support cylinder. A controller integrated circuit may control the power stage through the main BJT’s emitter pin in an emitter-controlled BJT-based power stage. A second deposition step is performed for completing the deposition. Coupled to the transform module is a lighting module which is positioned on the single semiconductor platform for performing lighting operations on the data received from the transform module. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which the dipeptidyl peptidase-IV enzyme is involved.
