Abstract: This invention provides a device and method for perforation of skin for the purpose of drawing blood or administering pharmaceuticals. The device incorporates a laser which produces a laser beam at an appropriate wavelength which is specifically focused to perforate the skin of a patient. Optionally a container can be incorporated in the device for collecion of blood from the perforated tissue.

Abstract: A multi-function endoscope capable of insertion within a body cavity for treatment/diagnostic purposes. The endoscope includes a flexible probe having an optical fiber connected to a laser light source, an optical fiber bundle connected to an illuminating light source, and another optical fiber bundle with a focusing lens thereon connected to a viewing system. The probe further includes an optical fiber having a sensor system associated therewith for making temperature and fluid pressure measurements within the body cavity. Also included are fluid conduits through the probe, and detecting wires for receiving electrical potentials from body cavity tissues. Finally, the probe includes steering wires which, when moved, cause probe movement. The steering wires are moved using a manipulator system consisting of stepper motors connected to a computer controller.
