摘要： A hand-held, fiber optic based dental device with optical coherence domain reflectometry (OCDR) sensing capabilities provides a profile of optical scattering as a function of depth in the tissue at the point where the tip of the dental explorer touches the tissue. This system provides information on the internal structure of the dental tissue, which is then used to detect caries and periodontal disease. A series of profiles of optical scattering or tissue microstructure are generated by moving the explorer across the tooth or other tissue. The profiles are combined to form a cross-sectional, or optical coherence tomography (OCT), image.

摘要： A compact laser system that removes surface coatings (such as paint, dirt, etc.) at a removal rate as high as 1000 ft.sup.2 /hr or more without damaging the surface. A high repetition rate laser with multiple amplification passes propagating through at least one optical amplifier is used, along with a delivery system consisting of a telescoping and articulating tube which also contains an evacuation system for simultaneously sweeping up the debris produced in the process. The amplified beam can be converted to an output beam by passively switching the polarization of at least one amplified beam. The system also has a personal safety system which protects against accidental exposures.

摘要： An apparatus and method for determining the orientation of a device with respect to an x-ray source. In one embodiment, the present invention is coupled to a medical device in order to determine the rotational orientation of the medical device with respect to the x-ray source. In such an embodiment, the present invention is comprised of a scintillator portion which is adapted to emit photons upon the absorption of x-rays emitted from the x-ray source. An x-ray blocking portion is coupled to the scintillator portion. The x-ray blocking portion is disposed so as to vary the quantity of x-rays which penetrate the scintillator portion based upon the particular rotational orientation of the medical device with respect to the x-ray source. A photon transport mechanism is also coupled to the scintillator portion. The photon transport mechanism is adapted to pass the photons emitted from the scintillator portion to an electronics portion. By analyzing the quantity of the photons, the electronics portion determines the rotational orientation of the medical device with respect to the x-ray source.

摘要： Optical ear infection treatment device and methods are described where an LED and optical light pipe are used to deliver the light from the LED to the middle ear of a patient to reduce bacterial growth and/or eliminate bacteria. Typically, the device is placed in the ear and then activated by the user by pressing an activation button. Once activated the control electronics will turn on the LED and perform a treatment. The most basic treatment mode comprises turning on the LED at maximum power for a predetermined period, e.g. 30 minutes, 60 minutes. When the preset duration is completed, the device will notify the user by an audible beep or vibration that the treatment is complete. Once completed, the user can remove the device, the treatment could be repeated once a day or for extreme cases multiple times during the day.

摘要： A device is described that can be easily used to warn an asthmatic or allergen reacting patient of irritant levels which may trigger an asthma or allergy attack for that person. The device continually monitors and records irritants in the air, and when the concentration exceeds the predefined level the device generates an alarm signal for the user. The recorded data can be downloaded to a computer, and this information can be used by the patient and the physician to identify irritants, guide treatment, and determine threshold levels.

摘要： The human face is efficiently and precisely dissected while radioifrequency energy is applied to controllably release target tissue bonds and alter surrounding tissues in such a fashion that these facial tissues contract and tighten in response to the energy application while automatically excluding vital nerves and vessels. Tightening will be most dramatic in younger patients between 45 and 55 years of age such that the surgeon may not have to cut-out or stretch skin for a desirable effect in most of this population. The device is inserted through only 3 relatively small 1 cm incisions allowing energy to be applied to the upper subcutaneous, lower dermal and platysmal face-lift layers. The procedures take less than 15 minutes following anesthesia and the effects will last for at least several years. The special arrangement of protrusions and recessions on the tip of the instrument allows the surgeon to efficiently force the device through face-lift planes with instantaneous knowledge of the location and progress simply by the “feel” of the apparatus. Vibrational energy and optional ultrasonic means will yield speed enhancement and tip debris and char reduction. The device and method permit efficient tissue separation and alteration of the lower face-neck-unit tissues, mid-face-unit tissues and scalp-forehead-temple-unit tissues.
摘要翻译：人类的面部被有效和准确地解剖，同时施加射频能量以可控制地释放目标组织粘结并改变周围组织，使得这些面部组织响应于能量应用而收缩和收紧，同时自动排除重要的神经和血管。年龄在45至55岁之间的年轻患者的紧缩将最为戏剧化，因此外科医生可能无需在大多数人群中切开或拉伸皮肤，达到理想的效果。该装置仅插入3个相对较小的1cm切口，允许将能量施加到上皮下，低皮层和前列腺提升层。手术在麻醉后不到15分钟，效果至少持续数年。在仪器尖端上的突出和凹陷的特殊布置允许外科医生有效地迫使装置通过面部提升平面，其瞬间了解位置并且简单地通过装置的“感觉”进行进展。振动能量和可选的超声波装置将产生速度增强和尖端碎屑和焦炭减少。该装置和方法允许有效的组织分离和改变下面部颈部单元组织，中间单位组织和头皮前额 - 单位组织。

摘要： A guidance and viewing system based on multiplexed optical coherence domain reflectometry is incorporated into a catheter, endoscope, or other medical device to measure the location, thickness, and structure of the arterial walls or other intra-cavity regions at discrete points on the medical device during minimally invasive medical procedures. The information will be used both to guide the device through the body and to evaluate the tissue through which the device is being passed. Multiple optical fibers are situated along the circumference of the device. Light from the distal end of each fiber is directed onto the interior cavity walls via small diameter optics (such as gradient index lenses and mirrored corner cubes). Both forward viewing and side viewing fibers can be included. The light reflected or scattered from the cavity walls is then collected by the fibers and multiplexed at the proximal end to the sample arm of an optical low coherence reflectometer. The system may also be implemented in a nonmedical inspection device.
