  • Patent number: 7177695
    Abstract: A device and method is disclosed for the treatment of early stage wounds, i.e. those wounds that have resulted in little or no breach of the skin tissue. The invention utilizes non-ablative laser or non-coherent electromagnetic radiation applied to a stage one or two wound to stimulate wound healing, destroy viral and bacterial bodies, and prevent the development of such wounds into higher stage wounds. An appropriate wavelength is chosen from the range of 193 nm to 10.6 microns, and is delivered at a power density of about at least 1 W/cm2 over a predetermined treatment duration typically in the range of 1 second to 3 minutes. To achieve the desired energy density, radiation is typically delivered at a power between 1 Watt and 15 Watts, with an average power of 5–10 Watts. Early stage wounds that can be addressed with this invention include but are not limited to spider or other insect bites, bee stings, rashes, eczema, psoriasis, and poison ivy.

  • Patent number: 5908418
    Abstract: A hand held coagulating device exhibiting superior radiation transfer characteristics and providing a cooled handle for improved user comfort. An exemplary embodiment includes an outer shell housing internal components of the device and providing a surface at which a user of the device can hold the device during a surgical procedure. A contact element positioned in an opening in a forward end of the shell is placed against an area of tissue or blood to be coagulated, and radiation produced by a radiation source, such as an incandescent lamp, is transmitted through the contact element to the tissue or blood for an appropriate period of time. In one embodiment, a curved reflector is disposed near the radiation source to direct the radiation toward the contact element, and a conical collector is situated between the radiation source and the contact element to focus the radiation through the contact element.

  • Patent number: 5860968
    Abstract: A laser scanning method and apparatus having a scanning hand piece 18 connected at the free end 20 of a hollow wave guide 14 to scan a beam of laser energy 22 in a predetermined pattern to uniformly ablate in an enlarged target area. The hand piece 18 includes a hollow shaft motor 40 having a conduit mounted therein for conducting the beam of laser energy 22. The conduit 54 has a proximal end 56 in axial alignment with the longitudinal axis 60 of the hollow shaft 48 and in light energy communication with the laser energy generator 12. The distal end 58 of the conduit 54 is mounted in the hollow shaft 48 so that it is eccentrically positioned with respect to the axis 60 of the hollow shaft 48. When the motor 40 is energized, the hollow shaft 48 rotates the distal end 58 of the conduit 54 in a predetermined circular pattern to scan the laser energy uniformly and thoroughly over the tissue in the target area.

  • Patent number: 5851221
    Abstract: An implantable medical device of the type formed of a hermetically sealed enclosure attached on a enclosure attachment surface thereof to a module attachment surface of a pre-formed header module is disclosed. The pre-formed header module is attached to the enclosure attachment surface through use of a retention structure extending away from the enclosure surface into proximity with a portion of the pre-formed header module when the enclosure and module attachment surfaces are aligned with respect to one another. The retention structure comprises a bendable member that is bent from an initial position allowing the pre-formed header module to be seated with respect to the hermetically sealed enclosure to a retention position making an attachment against a bend engaging portion of the pre-formed header module.

  • Patent number: 5514168
    Abstract: A new method of treatment of vascular headaches (migraine, cluster) as well as atypical pain is presented, comprising the application of bursts of low power laser light to the area of intra-oral tenderness associated with the above conditions. This zone of tenderness is in the area of the plexus formed by the posterior and middle superior alveolar branches of the ipsilateral maxillary nerve. The intra-oral tenderness associated with vascular headaches and facial pain disappears almost immediately, returning in approximately three hours to a few days. With repeated applications, a marked decrease/elimination of the intra-oral tenderness and similar elimination of vascular headache and facial pain frequency and intensity has been observed. The treatment comprises the brief application of bursts of low power laser light (non-cutting 2 mW) from a low-power helium-neon laser, having a maximum output of 5 mW, utilizing an application time of 20 to 30 seconds.

  • Patent number: 5412561
    Abstract: A method of analyzing serial automated visual field data calculates a total field vector of the threshold sensitivity of points in a visual field and compares the total field vector with a calculated normal field vector for a given patient. The vector angle between the total field vector and the normal field vector is calculated to determine the distribution of threshold sensitivities to characterize the localization and the magnitude of field changes. In one embodiment, the sensitivities of each point in the visual field with respect to normal sensitivities for each point is plotted for each of a series of time spaced visual field tests. The single plot uses a line symmetrical about a zero axis whose magnitude reflects the difference from the norm for each point in each exam and forms a graphic depiction of changes in the visual field at each point over a series of visual field tests.
