  • Patent number: 8897326
    Abstract: In a method, a gain medium is provided having an absorption coefficient that varies with wavelength. An absorption coefficient curve of the absorption coefficient or a range of wavelengths comprises peaks and valleys. A pump module is operated to output pump energy at an operating wavelength within one of the valleys, at which the absorption coefficient is approximately less than 40% of the absorption coefficient at an adjacent peak of the absorption coefficient curve defining the valley. The pump energy is directed through the gain medium. A portion of the pump energy is absorbed with the gain medium and laser light is emitted from the gain medium responsive to the absorbed pump energy. The non-absorbed pump energy (feedback pump energy) is fed back to the pump module. The operating wavelength of the pump energy is stabilized using the feedback pump energy.

  • Patent number: 8858542
    Abstract: A medical laser system and related methods of utilizing cooling within and around an optical fiber tip to prevent premature failure of the optical fiber. The optical fiber is surrounded by a protective jacket assembly including a body tube assembly, and a tip cap assembly. The body tube assembly includes an internal fiber jacket, and an external body tube with a body tube channel defined therebetween. The tip cap assembly includes an inner cap member and an outer cap member defining a cap irrigation channel therebetween. Together, the cap irrigation channel and body tube channel cooperatively define an internal irrigation channel. The optical fiber can be delivered to a treatment location through a cystoscope. Saline is directed through an external irrigation channel between the cystoscope and the protective jacket assembly, as well as the internal irrigation channel to cool the fiber tip and prevent overheating and failure of the optical fiber.

  • Patent number: 8845514
    Abstract: The present invention provides a urethral prosthesis including a first and a second arm that join to form a junction, and a stem that is also joined to the junction. The junction is adapted to exert sufficient pressure on a portion of a patient's urethra to prevent unintentional voiding of the patient's bladder. However, upon exerting a tension force on the stem, the pressure exerted by the junction is reduced such that the patient's bladder may be intentionally voided.
