  • Publication number: 20150073322
    Abstract: The current invention is an accommodating apparel or brace. It is intended to be convenient and comfortable. When the brace wearer is at rest, the brace exerts only modest forces against the body. When the brace wearer is active, the brace tightens and diverts load to protect the body part. The brace accommodation may include application of stronger fixation when activity begins and which persists as long as the activity does. It may also include application of forces around the body part to shift load away from the target part. The accommodation also includes relaxation of forces applied to the wearer when the wearer relaxes.

  • Patent number: 7169755
    Abstract: An improved solution for use in the removal of cataractous lenses via liquefracture is described. The liquefracture solution contains a viscosity-enhancing agent to increase the residence time of the solution in the heating chamber of the liquefracture handpiece, thereby increasing the expulsion force of the solution from the handpiece (i.e., “pulse force”). An agent that releases gas when the liquefracture solution is heated in the handpiece may also be included in the solution, thereby also enhancing the pulse force of the solution upon expulsion from the handpiece. The solution preferably also contains a partially water-soluble agent that forms a temporarily insoluble precipitate when heated in a liquefracture handpiece. The precipitate acts as an abrasive agent when expelled with the liquefracture solution from the handpiece, thereby facilitating the cutting and disintegration of the cataractous lens material.

  • Patent number: 7160289
    Abstract: A blood vessel occlusion system and method includes a handheld probe including a power source, the probe being adapted to transmit energy from the power source through a body surface and into a target blood vessel, for example a varicose vein. Further included is a manual or automatic switch mechanism adapted to enable and disable the power source in response to a predetermined level of compression applied, by means of the probe against the target blood vessel. When the blood vessel is compressed sufficiently to collapse and substantially slow or substantially prevent a flow of blood therethrough, the power source is activated and the vessel is cauterized, leaving the blood vessel in a condition that is resistant to recanalization.

  • Patent number: 7047564
    Abstract: The invention is designed to eliminate or minimize the liability associated with “packet flooding” attacks originating from within a local area network connected to an external network such as one controlled by a university or governmental organization. In these attacks, an attacker uses up all available bandwidth to a victim with useless data. The invention performs its function by identifying and classifying data packets arriving at a “Reverse Firewall” for transmission to the external network using various techniques. For example, data packets that are sent in response to data packets received from the external network will receive a different classification and thus allocation of resources than data packets not sent in response to previously received packets.

  • Patent number: 6860868
    Abstract: A surgical handpiece having at least two lumens or tubes mounted to a body. At least one tube is used for aspiration and at least one other tube is used to inject heated surgical fluid for liquefying a cataractous lens. A portion of the second tube is enlarged to form a pumping chamber. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the second tube. The pumping chamber may use a pair of electrodes.

  • Patent number: 6589204
    Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to great an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The electrodes are insulated from each other.

The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The distal end of the annular gap is sealed by sealing together the distal ends of the first and second tube and a plurality or orifices or ports may be formed near the seal. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifices in a controlled and directed manner. The distal end of the first and second tubes may contain a bend.

  • Patent number: 6579270
    Abstract: A surgical handpiece and tip having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The distal end of the annular gap is sealed by a nozzle at the distal ends of the first and second tube and a plurality of orifices or ports may be formed in the nozzle. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifice in a controlled and directed manner.
