Paper Abstract

In the early 1980s selective photothermolysis (SPT) was introduced. As a consequence a class of SPT lasers was developed with particular attention being centered on the removal of disfiguring vascular lesions, including port wine stains. This talk discusses the recently introduced Vascular System from Medical Bio Care, Sweden, also supplied through Derma- Lase. This system produces a variable pulsewidth in the range of 450 microsecond(s) to 10 ms. This range has been identified as optimal as it provides the theoretical possibility of matching laser pulsewidth with the theoretical relaxation time of most vascular lesions. The tunable wavelength includes 585 nm. The clinician can therefore tailor the options to match the characteristics of the individual lesion. Operation with close multiple pulses in a burst is also an option. The system consists of a compact solid state host mated to a unique delivery system.
