Patent number: 9680281Abstract: In a method, a laser pump module is set to a first power mode and pump energy is output at a first power level through the activation of a first subset of laser diodes. Laser light is emitted from a gain medium at the first power level in response to absorption of the pump energy. An operator input corresponding to a power mode setting is received. The laser pump module is switched to a second power mode and pump energy is output at a second power level through the activation of a second subset of the laser diodes. Laser light is emitted from the gain medium at the second power level in response to absorption of the pump energy.Type: GrantFiled: February 12, 2015Date of Patent: June 13, 2017Assignee: Boston Scientific Scimed, Inc.Inventors: Rongwei Jason Xuan, Michael R. Hodel, Douglas G. Stinson, Raymond Adam Nemeyer

Patent number: 9574759Abstract: A laser illuminator emitting a circular profile of substantially uniform intensity is presented. The laser illuminator may include a heat sink configured to optically couple to a laser light source. The heat sink may include a beam dump cavity configured to absorb light from the laser light source, and a circularizer aperture having a cylindrical, flat-top opening and being configured to shape a portion of laser light emitted from the laser light source to exit the heat sink. The laser illuminator may also include a collimation lens configured to collect the light exited from the heat sink and provide a focused beam of light, and a scatter clean-up aperture optically coupled to the collimation lens. The scatter clean-up aperture may be configured to absorb scatter laser light rays, and provide from the focused beam of light an output beam of light comprising a circular profile of substantially uniform intensity.Type: GrantFiled: January 16, 2015Date of Patent: February 21, 2017Assignee: Steiner eOptics, Inc.Inventor: Adam Nemeyer

Publication number: 20160354147Abstract: An apparatus (100) has a pump module (104) providing pump energy, a resonator (106) and a controller (187). The resonator (106) includes a gain medium (102) receiving the pump energy from the pump module and producing light; reflective surfaces (110, 156, 158, 160, 162) reflecting light produced by the gain medium back toward the gain medium; and a variable light attenuator (152) receiving light produced by the gain medium. The controller (187) controls the amount of light attenuated by the variable light attenuator such that the apparatus emits windows (306, 308, 310) of pulses of laser light at spaced time intervals, each window containing a plurality of pulses of laser light and each interval (326, 327) between windows being larger than an interval (318) between pulses within a window. The emitted windows of pulses (320, 322) of laser light heat tissue to a temperature that causes coagulation without vaporization.Type: ApplicationFiled: August 18, 2016Publication date: December 8, 2016Applicant: Boston Scientific Scimed, Inc.Inventors: Hyun Wook Kang, Raymond Adam Nemeyer, Michael Ray Hodel

Patent number: 9407058Abstract: In a method of stabilizing pump energy, 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. Pump energy is generated at an operating wavelength within one of the valleys, at which the absorption coefficient is approximately at a minimum. The pump energy is transmitted 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.Type: GrantFiled: November 4, 2014Date of Patent: August 2, 2016Assignee: Boston Scientific Scimed, Inc.Inventors: Edward D.

Patent number: 9395066Abstract: An adjustable beam illuminator may provide a beam of light with an output cone angle that is adjustable (e.g., continuously adjustable) from small output angles (substantially collimated beam, “spot” mode) to larger output angles providing “flood” illumination. The illuminator may emit infrared light, for example.Type: GrantFiled: January 13, 2012Date of Patent: July 19, 2016Assignee: LASER DEVICES, INC.Inventor: Adam Nemeyer

Patent number: 9232959Abstract: Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.Type: GrantFiled: February 4, 2010Date of Patent: January 12, 2016Assignee: AQUABEAM, LLCInventors: Nikolai Aljuri, Ajit Nair, Paren Shah, Adam Nemeyer, Daniel Grupp
