    摘要： A polypectomy device and method which includes a snare cable, a fixed jaw and a moveable jaw. The snare cable is routed through both the fixed jaw and the moveable jaw. The snare cable forms a hoop for encircling the polyp. Shortening the snare cable positions the jaws about the base of the polyp and further shortening the cable closes the jaws. The fixed jaw includes a heating element which cauterizes the base of the polyp. The closing of the jaws and the heating of the heating element cuts and seals the polyp.

    摘要： To provide a medical energy irradiation apparatus which, having a simple and inexpensively manufacturable structure, enables a doctor using it in the heat curing of prostatic hypertrophy or the like to accurately and stably irradiate a prescribed site deep in a living body with a laser beam and, even if its observation window is smeared, to observe tissues of a living body. An inserting portion of the medical energy irradiation apparatus to be inserted into a living body according to the invention has an emitting portion for emitting a laser beam toward tissues of the living body; an observation window, provided near the tip of the inserting portion in its inserting direction, for observing the tissues of the living body; and a hollow pipe for supporting a supporting member, which supports the emitting portion, shiftably in the lengthwise directions of the inserting portion and feeding detergent to the observation window. Therefore, when the observation window is smeared, detergent can be fed to the observation window to remove the smear of the observation window.

    摘要： The invention provides a method of sensitising target cells to ultrasound energy using a stimulus such as an electric field. This nullelectrosensitisationnull enables target cells to be disrupted by ultrasound at frequencies and energies of ultrasound which do not cause disruption of non-sensitised (i.e., non-target) cells. As a consequence, the method increases the selectivity of ultrasound therapy, providing a way to ablate undesired cells, such as diseased cells (e.g., tumor cells) while minimising harm to neighboring cells. In another aspect, however, ultrasound can be used to sensitise cells while the electrical field is used to disrupt cells. The invention also provides an apparatus for performing the method and assays for identifying gene products and other molecules involved in apoptosis.

    摘要： An MRI guided surgical apparatus includes a heat source formed by a laser and an optical fiber carrying the heat energy into a part to be coagulated by hyperthermia with an end reflector to direct the energy in a beam to one side of the fiber end. A reinforcing sleeve for the fiber is mounted in a shielded, Piezo-electric motor which causes movement of the fiber longitudinally and angularly within a rigid elongate cannula. A magnetic resonance imaging system is arranged to generate a series of output signals over a period of time representative of temperature in the part as the temperature of the part changes during that time. The heat source is controlled in heat energy applied and location and orientation of the beam to stop heating when the temperature at the boundary of a tumor reaches the required hyperthermic temperature. Cooling of the tip portion of the probe is effected by expansion of a supplied cooling fluid in gaseous form through a restrictive orifice into an expansion zone at the probe end. The fiber is thus encased in a stiff tubular titanium probe with a relatively small fluid supply duct along the inside of the probe with the interior of the probe acting as a return duct for the expanded gas. Thus the fiber end is contained in gas rather than liquid and the temperature of the probe end can be monitored by a sensor in the probe end and controlled by controlling the pressure in the supplied cooling fluid. The probe is driven in the longitudinal and rotational directions to move the fiber tip.

    摘要： Systems and methods for reducing or minimizing post-surgical complications are described. By applying energy to tissues under specifically controlled conditions, the formation of adhesions in response to cutting or other damage of those tissue may be eliminated or significantly reduced. According to an embodiment of the method of the invention, energy application is controlled to heat the tissue within a range of 61 to 100 degrees centigrade. In one embodiment, the system of the invention includes an easily manipulated applicator, having a scissor-like configuration and a controller for the energy application.

    摘要： A surgical apparatus for delivering a conductive fluid to a target site for subsequent formation of a virtual electrode to ablate bodily tissue at the target site by applying a current to the delivered conductive fluid. The surgical apparatus includes an elongated device forming a helical needle. The helical needle is configured to engage bodily tissue and is hollow for delivering conductive fluid from a fluid source. Finally, the helical needle terminates in a needle tip. In one preferred embodiment, an electrode is associated with the helical needle for applying a current to conductive fluid delivered from the helical needle. During use, following delivery of conductive fluid, the electrode applies a current to the delivered conductive fluid for creating a virtual electrode. The virtual electrode ablates bodily tissue contacted by the conductive fluid.
