Abstract: 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.

Abstract: A medical instrument includes two jaw members, at least one of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes a light source that provides a light beam for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue.

Abstract: 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.

Abstract: An ablation probe comprising an elongate body extending a length along a longitudinal axis from a first end to a second end, the first end extending into a housing and the second end comprising an ablation probe tip configured for insertion into a biopsy tract in a patient. In example forms, the elongate body of the ablation probe can be inserted into a patient through an existing trocar needle or biopsy access cannula following completion of a biopsy. In other example forms, the elongate body of the ablation probe defines a lumen. In one example form, the lumen contains a wire for heating the ablation probe tip, which may be composed of graphite, a resistive metal, or another electrically-resistive material. In another example form, the lumen additionally contains a thermocouple or other temperature sensor for monitoring the temperature of the ablation probe tip. In any of the above example forms, use of the ablation probe to heat tissue following a biopsy effects cauterization of the tissue, stopping bleeding and reducing or preventing the seeding of additional tumors.

Abstract: Disclosed is an apparatus and a method to preserve linearly polarized laser beam when it passes through a freely twisting beam delivery system such as an articulated arm. The polarization of the output beam from the delivery system will be stable and the same as the polarization of the input beam to the delivery system, and can be used to pump anisotropic laser crystals as well as nonlinear optical crystals.

Abstract: A robotic surgical system includes a surgical instrument configured to cut biological tissues and an imaging system configured to image the biological tissues. Based on one or more images of the biological tissue generated by the imager, the robotic surgical system operates the surgical instrument to cut the biological tissue according to a desired dissection of the tissue. The robotic surgical system operates the surgical instrument to partially or wholly automatically perform one or more cuts into the biological tissue to achieve the desired dissection.
