摘要:
Improved, efficient devices/methods for medical and cosmetic applications, involving the delivery of laser energy to tissue are provided. In a preferred embodiment a portable, easy-to-use laser system comprises at least one laser source operating at one or more laser wavelengths; an electronic visual display having a n- dimensional input interface to set/select laser parameters; and at least one waveguide optically coupled to the laser source to convey laser radiation to a treatment site. The n-dimensional input interface inputs/selects lasing parameters which allows the selection of a combination of output wavelengths and powers by simply touching the electronic visual display.. Method of use comprises the steps of placing at least one waveguide at preselected treatment site; selecting a combination of laser wavelengths and power by interacting with an electronic visual display; and irradiating the treatment site.

Minimally invasive methods and devices for endoluminally treating female fallopian tubes or male vas deferens of mammals are presented as a permanent method of contraception. In preferred embodiments, medical devices for male and female sterilization comprise laser radiation source operating at one or more preselected wavelengths between about 980nm and about 1950nm, preferably at least one of 980nm, 1470nm and 1950nm; treatment waveguide with a radial or cylindrical radiation emitting tip; viewing scope; and a temperature sensor. In another preferred embodiment, a minimally-invasive permanent contraception method for males and females comprises the steps of introducing at least one treatment waveguide in a body cavity; positioning the treatment waveguide inside a body cavity; irradiating; and repeating the procedure in companion body cavity to inhibit fertilization. In another embodiment, fluids are infused and/or extracted after, before or during the procedure to enhance laser energy absorption and enhance efficiency of laser treatment.

In one aspect, a seismic data acquisition unit is disclosed including a closed housing containing: a seismic sensor; a processor operatively coupled to the seismic sensor; a memory operatively coupled to the processor to record seismic data from the sensor; and a power source configured to power the sensor, processor and memory. The sensor, processor, memory and power source are configured to be assemble as an operable unit in the absence of the closed housing.

An improved method and device is provided for safe and efficient low power density endoluminal treatment of venous insufficiency. One such device emits pulsed or continuous energy radially through an optical fiber end with a conical shaped tip for 3600 radial emission. In some embodiments, a conical reflective surface is distally spaced opposite to and faces the emitting tip for enhancing radial emission efficiency by reflecting out any designed or remnant forwardly transmitted energy in radial directions. Other devices include flat emitting faces sealed within protective, radiation transparent covers. Laser radiation is transmitted at a wavelength and power such that is it substantially entirely absorbed within the blood vessel wall to sufficiently damage the intravascular endothelium and, in turn, achieve blood vessel closure. Because the energy is substantially entirely absorbed within the blood vessel wall, the need for a local anesthetic along the treatment area of the blood vessel may be substantially avoided.

Connectors for optically coupling radiation accurately from radiation sources into waveguides in medical applications are provided. A preferred embodiment for coupling laser sources into optical fibers provides a connector comprising an outer body for handling connector; a two-part ferrule; an inner body which protects ferrule and holds its two parts together; a collet chuck through which an optical fiber is introduced; a spring; a ferrule interlock; and bending protection with a long fiber protection end. Main features are that the inner body moves within the outer body longitudinally, the spring-loaded ferrules move against a fixed position element in the laser housing via the spring load, and their relative shapes are designed to be assembled in only one possible angle position,thus maintaining alignment of elements to reduce/avoid lost power absorbed by the connector's proximal end due to coupling. The ferrule is mounted inside the connector and does not emerge from it for protecting the ferrule. In another embodiment the connector provides an electronic signature such as an RFID tag for waveguide recognition in a position close enough to the laser source to ensure identification. Additionally, the connector has an optional electric power and signal port.
