  • High voltage resonant inverter for capacitive load
    Patent number: 5287262
    Abstract: An inductor is connected in parallel with an electrical load which, together with the capacitive components of the load, forms a resonant circuit. An auxiliary inductance coupled to the aforesaid conductor is energized periodically. During the oscillations, the resonant circuit delivers the energy to the load. The power dissipation of the switches is very low, due to the auxiliary inductance and the resonant circuit. The high-voltage generator is particularly suitable for gas lasers.

  • Optical transmission device
    Patent number: 5097525
    Abstract: An optical transmission device comprising a body, a tapered surface disposed in the body, and means for attaching an optical transmission means to the body. In the preferred embodiment, the optical transmission means is a hollow waveguide. The tapered surface has an inlet aperture for receiving radiation and an outlet aperture. The diameter of the outlet aperture of the tapered surface is smaller than the inner diameter of the hollow waveguide.

  • Apparatus for directing 10.6 micron laser radiation to a tissue site
    Patent number: 5074860
    Abstract: A CO.sub.2 (10.6 micron) medical delivery end probe is described which enables line-of-sight viewing of a surgical site internally within a body within the very same endoscope used to house the probe. The end probe includes two different sections of n<1 air core hollow waveguides, obliquely related to one another. A mirror is positioned to reflect radiation from the exit end of the initial guide to the entry end of the main section. A bridge which is especially adapted for use in an endoscope with both such a probe and a telescope is also described. Moreover, an adapter having the initial optical guide section discussed above enabling straight end probes to be used is also described.

  • Delivery arrangement for a laser medical system
    Patent number: 4917083
    Abstract: A delivery arrangement for CO.sub.2 (carbon dioxide) laser radiation is described which is particularly designed for laser medical systems. The delivery arrangement has three components--an articulated arm connectable to a CO.sub.2 laser head, a waveguide probe for directing CO.sub.2 laser radiation to an operating site, and a coupler for conditioning CO.sub.2 laser radiation emanating from the arm for coupling into the waveguide probe.
