Abstract: This disclosure relates to methods for isolating bacterial cells, fungal cells, and single-celled parasites present in a blood sample containing higher eukaryotic cells; particularly wherein the microorganisms are present at a concentration significantly lower than the eukaryotic cells in the sample.

Abstract: Apparatus is described including a tool, the tool including a shaft having a distal portion that is sized and shaped to be inserted into a subject during a surgical procedure. The tool includes a tissue-treatment tip, at the distal portion, that defines a beam deflector. An optical fiber is positioned to emit laser energy into the beam deflector. The beam deflector has a deflector surface, a first portion of which is shaped and positioned to reflect the laser energy toward a tissue-treatment tip surface, and a second portion of which is configured to absorb the laser energy and thermally conduct the absorbed energy to the tissue-treatment tip surface. The tissue-treatment tip surface is configured to thermally conduct the absorbed energy to the tissue by contacting the tissue. Other embodiments are also described.

Abstract: Apparatus comprises: (a) a longitudinal member (32), having a distal portion (34); (b) a plurality of electrodes (38) disposed on the distal portion of the longitudinal member, such that a first electrode (38a) of the plurality of electrodes is disposed distally along the longitudinal member from a second electrode (38b) of the plurality of electrodes; and (c) a controller (40). The controller comprises an actuator, and circuitry (42) electrically connected to the electrodes via the longitudinal member. The actuator is configured to move the longitudinal member in discrete incremental movements such that for each incremental movement, (i) before the incremental movement the first electrode is disposed in a starting position, (ii) during each incremental movement the actuator moves second electrode toward the starting position, and (iii) at the end of each incremental movement the second electrode is stationary at the starting position.

Abstract: A tool has a handle and an elongate shaft that extends distally from the handle. A distal portion of the shaft is inserted into a subject during a surgical procedure. An optical fiber delivers laser energy to a tip at the distal portion of the shaft. The tip includes a mechanical cutting mechanism including a moving part that absorbs the laser energy, thermally conducts the absorbed energy to tissue that is disposed between the moving part and another part, and moves with respect to the other part in order to cut tissue that is disposed between the parts using a mechanical force that is lower than a mechanical force that would be required to cut the tissue in the absence of the laser energy. Other embodiments are also described.

Abstract: An online protection system and method for actively filtering webpages using a rule-based protective agent such that internet connectable communication devices receive a clean copy of the webpage. The protective agent may be operable to perform rule based filtering of static and web-generated pages. The system includes a data scanner, a report processor and a rule-based logic generator. The protection system may include malware server site scanner to prevent any potential backdoors and possibly introducing remedy to the infected files or quarantining in a non-standard directory locations.

Abstract: The present invention relates to a device, system and method for assisting the positioning of medical instruments. The system comprises a hollow tubular member such as a sheath or sleeve comprising a rotational indicator element. The system further comprises an elongated rod having a blade on its distal end and comprising a rotational indicator element (aligned with the blade orientation) and a stopper close to its proximal end.

Abstract: A system and method for protecting at least one server, in communication with a computer network, from hacking attacks including a scanner, a report processor and a control center. The scanner may monitor activity of the server, identify at least one security vulnerability, produce an automated report. The report processor may analyze the automated report and generate fixes for identified vulnerabilities.

Abstract: The present invention relates to apparatus and methods for thermally ablating uterine fibroids. More particularly, the present invention relates to a conduit having a plurality of channels for delivering a plurality of thermal ablation probes to an organic target such as a uterine fibroid, the probes being delivered in such configuration and orientation as to enable efficient and thorough ablation of the fibroid. In a preferred embodiment, the conduit is formed as a sleeve having a large central lumen sized to accommodate a hysteroscope, channels sized to accommodate cryoprobes are used as thermal ablation probes, and comprises thermal insulation materials serving to protect the cervix from damage by cold. The present invention further relates to bent cryoprobes usable in conjunction with such a conduit and designed to exit therefrom in a desired configuration useful for ablating a large fibroid.

Abstract: Display devices in the shape of a flag assembly are provided. The display devices are constructed of solid plastic materials that withstand damage caused by contact with air turbulence or adverse weather conditions, particularly when attached to a mount on a moving vehicle, and that withstand detachment from a mount caused by such air turbulence or adverse weather conditions. The display devices allow an observer to openly view a display when a vehicle is stationary or moving, and allow a motorist of another vehicle to view the display while having an unobstructed view of traffic conditions surrounding the vehicle.
