摘要:
A method of treating a human body by destroying tissue cells is provided. The method involves positioning an electric field generating element near a target area containing tissue cells to be killed in the human body, and treating the human body by applying electrical pulses through the positioned electric field generating element in an amount above an upper limit of electroporation to irreversibly open pores in membranes of the tissue cells in the target area, thereby killing the tissue cells in the target area.

A method, apparatus and a system for thermally-assisted pulsed electromagnetic field stimulation for treatment of osteoarthritis are disclosed. In one embodiment, the system comprises a multi-coil applicator adapted for positioning near or around of the treated joint, a pulse generator functionally coupled to the applicator, a power supply, and a feedback loop for stabilizing the temperature of the joint. The feedback loop includes a heating element, a temperature sensor and an electronic controller for maintaining the temperature of the joint in the range of 38 to 42 degree C. At elevated temperatures the healing effect of PEMF stimulation on the cartilage is maximized and overall efficiency of the treatment is improved. To produce a high electric field, the coils of the applicator are made with a low number of turns, for example less than 5 turns, and are spatially arranged to cover the whole joint without “dead” zones.

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.

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. This temperature distribution can increase the selectivity of the treatment by increasing susceptibility of the neoplastic cells to the electroporation treatment and decreasing it for the normal urethral tissues.

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.
摘要:
An apparatus and method for non-invasive treatment in lieu of cosmetic surgery is disclosed. The apparatus comprises a combination of a high and low voltage pulse generators connected to two or more electrodes placed on a treatment site of the patient's body. High voltage pulses, delivered to the electrodes, create an electric field that kills subcutaneous fat cells. Low voltage pulses, delivered to the same or individual electrodes provide transcutaneous electrical nerve stimulation (TENS), blocking the signals of discomfort or pain that may arise from the high voltage pulsing.
