A system for direct imaging and diagnosing of abnormal cells in a target tissue includes a disposable optical speculum and an image acquisition system having the speculum assembled on and mechanically secured thereto. The image acquisition system is arranged to capture at least one of a single image or multiple images or video of cells within the target tissue using at least one of bright field or dark field ring illumination divided into independently operated segments to obtain a plurality of data sets. An image analysis and control unit in communication with the image acquisition system analyzes the data sets and applies algorithms to the data sets for diagnosing abnormal cells.

Disclosed is an applicator or handpiece configured to apply treatment energy to a segment of skin located in a tissue or skin treatment plane. The treatment energy could be RF energy, applied by a pair of bipolar RF electrodes or optical energy. The applicator includes an optical system configured to form a rectangular spot and homogenize the optical energy distribution.

Devices and methods are provided for indicating treatment efficiency by illuminating a signal onto surrounding tissue. The signal may be dynamic and is configured to indicate specific parameters of the treatment, the device and the patient. Various signal features may denote different parameters. Devices and methods are provided for maintaining a fiber tip effective throughout a treatment procedure by regenerating or replacing the tip. Devices and methods are provided for controlling emission from bended fibers. Cordless configurations of laser treatment devices are also provided.

A multi-function, adjustable chiropractic table comprises a body section fixed to a table frame. A cervical section is movably attached to the table frame and securable at a desired angle. The cervical section comprises a padded head support, forehead strap, and neck bolsters. The head support is slidably mounted in a tray and translatable therein using a scissors mechanism, for linear axial traction. Pivotally mounting the tray to the cervical section permits lateral traction. A four-bar linkage, including a base frame, permits raising/lowering of the table using an actuator activated by a foot triggered wave switch comprising proximity sensors. The body section comprises a chest, lumbar, and leg sections. The chest section is replaceable with a treatment nodule comprising hot and cold compresses, or a laser enhanced spinal decompression therapy apparatus comprising a laser driven by two linear actuators to emit light according to one or more treatment protocols.

In one embodiment, a handheld laser treatment apparatus comprises: a handset including a treatment chamber, the treatment chamber having an open treatment aperture; a laser array arranged to project optical energy into the treatment chamber and coupled to a power source; at least one vacuum channel positioned within the treatment chamber and coupled to a vacuum source; a trigger sensor coupled to logic that controls activation of the laser array and the vacuum channel; an attachment sensor arranged to detect which of a plurality of attachments are inserted into the treatment chamber through the treatment aperture. The logic enables activation of the vacuum channel when the attachment sensor detects a first attachment of the plurality of attachments inserted into the treatment aperture. The logic disables activation of the vacuum channel when the attachment sensor detects a second attachment of the plurality of attachments inserted into the treatment aperture.

A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.

The present invention relates to an optically diffusing fiber probe, a method for manufacturing the same, and an application thereof. More specifically, the present invention relates to an optically diffusing fiber probe capable of emitting light in a plurality of directions and a method for manufacturing the same, hybrid optical medical equipment for both diagnosis and treatment of tubular human tissue, a catheter-based laser treatment device, and an electromagnetic energy application device for tubular tissue stricture, comprising the optically diffusing fiber probe.

A multi-cladding optical fiber includes a core that conveys visible light used by a scanner for imaging a site within a patient's body, and an inner cladding that conveys high-power light, such as infrared light, used for providing therapy to site. The distal end of multi-cladding optical fiber is driven to scan the site when imaging or rendering therapy using an actuator. High-power light is coupled into inner cladding at proximal end of optical fiber using several different techniques. Some techniques use an axicon to direct the high-power light into the inner cladding, while visible light is coupled directly into the core. Another technique uses a multimode optical fiber in a coupling relationship with the multi-cladding optical fiber, to transfer high-power light from a core of the multimode fiber into the inner cladding of the multi-cladding optical fiber.

Devices and methods are provided for performing an ablation procedure on tissue with flow monitoring using flow sensors. The devices include a catheter, and at least one flow sensor disposed on the catheter, and a component for applying the ablation procedure. An assessment module provides an indication of the efficacy of the ablation procedure based on the flow measurement from the flow sensor.

A photoacoustic flow cytometry (PAFC) device for the in vivo detection of cells circulating in blood or lymphatic vessels is described. Ultrasound transducers attached to the skin of an organism detect the photoacoustic ultrasound waves emitted by target objects in response to their illumination by at least one pulse of laser energy delivered using at least one wavelength. The wavelengths of the laser light pulse may be varied to optimize the absorption of the laser energy by the target object. Target objects detected by the device may be unlabelled biological cells or cell products, contrast agents, or biological cells labeled with one or more contrast agents.
