  • Publication number: 20060217703
    Abstract: An apparatus and a method for treatment of benign prostatic hyperplasia are disclosed. The apparatus includes an applicator piece carrying a set of electrodes shaped and positioned to create a substantial electric field in the volume of hyperplasia and a pulse generator adapted for delivery of electrical pulses above the upper electroporation limit for the neoplastic cells. The amplitude, duration and number of the electrical pulses are generally selected to cause necrosis of a significant fraction of the volume of benign prostatic hyperplasia. The apparatus may include a high frequency system for heating the prostatic tissue and a cooling system for cooling the urethra. The combined action of heating and cooling may increase the temperature of the prostate cells to 45 degrees C. to 55 degrees C., while keeping the urinary tract at a temperature 15 degrees C. to 20 degrees C.

  • Patent number: 7086577
    Abstract: An emitter for a miniature X-ray apparatus comprises an insulating shell, an anode, and a cathode. The insulating shell includes a conical brazing surface, brazed to a conical brazing surface on the anode. The braze consists of a pure titanium layer and a pure tin layer. During brazing, the pure metals react and bond to the insulating shell and create a titanium-tin alloy between the pure layers. Pure tin is sputtered from tin sputter target onto the exposed brazing surfaces of the cathode cap and the anode. The insulating shell is placed in a vacuum chamber of deposition applicator, which deposits an active metal onto the shell brazing surface. In a brazing oven, the anode is placed within insulating shell such that the anode conical brazing surface and the shell conical brazing surface are contacting and aligned with each other. During brazing, the cathode is brought into contact with the insulating shell. The sealed emitters are placed in a sputtering machine's vacuum chamber.

  • Publication number: 20060079860
    Abstract: This invention provides an apparatus and method for emergency administration or self-administration of thrombolytic therapy in early stage of a heart attack. The apparatus includes a needle injector for making a venipuncture, a battery operated micro cooler for maintaining low temperature environment for vials with lyophilized thrombolytic and adjuvant drugs, a container with a diluent for reconstitution of the lyophilized drugs, a programmable infusion pump, and a microprocessor for controlling the process of infusion and recording the data. As the system is activated, said container becomes fluidly communicable with the infusion pump and vials with drugs in the cooler. Designed for autonomous execution of several schedules of infusion, it also can be controlled remotely by a qualified operator via an Internet interface.

  • Publication number: 20050182462
    Abstract: An apparatus and method for performing non-invasive treatment of the human face and body by electroporation in lieu of cosmetic surgery is provided. The apparatus comprises a high voltage pulse generator and an applicator having two or more electrodes in close mechanical and electrical contact with the patient's skin for applying the pulses to the patient's skin. The applicator may consist of two pieces with one electrode having a sharp tip and another having a flat surface. High voltage pulses delivered to the electrodes create at the tip of the sharp electrode an electric field high enough to cause death of relatively large subcutaneous fat cells by electroporation. Moving the electrode tip along the skin creates a line of necrotic subcutaneous fat cells, which later are metabolized by the body. Multiple applications of the electrode along predetermined lines on the face or neck create shrinkage of the skin and the subcutaneous fat volume underlying the treated area.
