Disclosed is a drug delivery system for delivering a drug at a sustained constant rate for a long period, which can be transplanted into an affected part safely and in a simple manner and can deliver a drug to the affected part for a long period. The present invention relates to a method for resolving stereoisomeric mixtures of thiols. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes. Thirdly transforming the first function into a first Fourier series and transforming the second function into a second Fourier series. The phase offset adjustment value may be updated andor recalculated continuously andor periodically and is added to or subtracted from the phase offset \u03bc as necessary.
