Publication number: 20080222231Abstract: The present invention relates to a digital system integration process through a virtual server (5), which comprises a process that distributes instances of message management and processing application according to the number of processors (9) present in each server (10). A message reader component (2) removes the message from one of the input queues (1) and verifies if it is a valid message. Then the messages are stored in the internal processing queue (3) according to the environment configurations and the application server (4) marks the message with the respective virtual server (5). The application server (4) removes the message from the processing queue (3) and delivers the message to the client application (6). Finally, the message is validated and, after it is processed, excluded from the database (8).Type: ApplicationFiled: June 2, 2005Publication date: September 11, 2008Inventors: Leonardo Larsen Ribeiro, Inivaldo Luiz da Silva

Publication number: 20060142750Abstract: Devices and methods for the treatment of skin conditions and lesions are disclosed herein. One aspect of the invention is a compact hand held device that can be safely used by those suffering from skin conditions, such as acne, warts, cold blisters, blemished skin, or fine wrinkles. The devices described herein employ the application of heat for the treatment of skin conditions and lesions. Typically, the peak temperatures employed are about 70° C. to about 400° C. by the devices, are achieved in less than about 1 second, and maintained for less than about 1 second. In some embodiments, the skin surface is heated with heat pulses. Thermal conduction transfers heat from the device to the skin and causes a biological response that accelerates acne clearing, treats blemished skin, itching, or fine wrinkles. The total heat transferred is low enough to prevent burns.Type: ApplicationFiled: December 9, 2005Publication date: June 29, 2006Inventors: Luiz Da Silva, George Choi

Publication number: 20050059940Abstract: Biocompatible materials are propelled at the skin with sufficient velocity to cause desired resurfacing of skin layers to the desired penetration depth. The materials, such as dry ice or water ice, are harmonious with the human body and thus eliminate foreign body reactions. Various materials may be used in combination, including local anesthetics and vasoconstrictors in solid or liquid form. The biocompatible solid or liquid particles are suspended in a cold carrier fluid and propelled through an insulated delivery system to the surface of the skin. The treatment of diseased skin lesions may be accomplished using the present invention as a drug delivery system.Type: ApplicationFiled: March 26, 2004Publication date: March 17, 2005Inventors: Paul Weber, Michael Weber, Luiz Da Silva

Publication number: 20050021013Abstract: Partial or total occlusions of fluid passages within the human body are removed by positioning an array of optical fibers in the passage and directing treatment radiation pulses along the fibers, one at a time, to generate a shock wave and hydrodynamic flows that strike and emulsify the occlusions. A preferred application is the removal of blood clots (thrombi and emboli) from small cerebral vessels to reverse the effects of an ischemic stroke. The operating parameters and techniques are chosen to minimize the amount of heating of the fragile cerebral vessel walls occurring during this photoacoustic treatment. One such technique is the optical monitoring of the existence of hydrodynamic flow generating vapor bubbles when they are expected to occur and stopping the heat generating pulses propagated along an optical fiber that is not generating such bubbles.Type: ApplicationFiled: September 10, 2002Publication date: January 27, 2005Inventors: Steven Visuri, Luiz Da Silva, Peter Celliers, Richard London, Duncan Maitland, Victor Esch

Patent number: 6484052Abstract: High frequency acoustic waves, analogous to ultrasound, can enhance the delivery of therapeutic compounds into cells. The compounds delivered may be chemotherapeutic drugs, antibiotics, photodynamic drugs or gene therapies. The therapeutic compounds are administered systemically, or preferably locally to the targeted site. Local delivery can be accomplished through a needle, cannula, or through a variety of vascular catheters, depending on the location of routes of access. To enhance the systemic or local delivery of the therapeutic compounds, high frequency acoustic waves are generated locally near the target site, and preferably near the site of compound administration. The acoustic waves are produced via laser radiation interaction with an absorbing media and can be produced via thermoelastic expansion, thermodynamic vaporization, material ablation, or plasma formation.Type: GrantFiled: March 30, 1999Date of Patent: November 19, 2002Assignee: The Regents of the University of CaliforniaInventors: Steven R. Visuri, Heather L. Campbell, Luiz Da Silva

Patent number: 6466713Abstract: The head of an optical fiber comprising the sensing probe of an optical heterodyne sensing device includes a planar surface that intersects the perpendicular to axial centerline of the fiber at a polishing angle &thgr;. The planar surface is coated with a reflective material so that light traveling axially through the fiber is reflected transverse to the fiber's axial centerline, and is emitted laterally through the side of the fiber. Alternatively, the planar surface can be left uncoated. The polishing angle &thgr; must be no greater than 39° or must be at least 51°. The emitted light is reflected from adjacent biological tissue, collected by the head, and then processed to provide real-time images of the tissue. The method for forming the planar surface includes shearing the end of the optical fiber and applying the reflective material before removing the buffer that circumscribes the cladding and the core.Type: GrantFiled: June 18, 2001Date of Patent: October 15, 2002Assignee: The Regents of the University of CaliforniaInventors: Matthew J. Everett, Billy W. Colston, Dale L. James, Steve Brown, Luiz Da Silva

Patent number: 6379325Abstract: This invention is an optically activated transducer for generating acoustic vibrations in a biological medium. The transducer is located at the end of a fiber optic which may be located within a catheter. Energy for operating the transducer is provided optically by laser light transmitted through the fiber optic to the transducer. Pulsed laser light is absorbed in the working fluid of the transducer to generate a thermal pressure and consequent adiabatic expansion of the transducer head such that it does work against the ambient medium. The transducer returns to its original state by a process of thermal cooling. The motion of the transducer within the ambient medium couples acoustic energy into the medium. By pulsing the laser at a high repetition rate (which may vary from CW to 100 kHz) an ultrasonic radiation field can be established locally in the medium.Type: GrantFiled: July 9, 1999Date of Patent: April 30, 2002Assignee: The Regents of the University of CaliforniaInventors: William Benett, Peter Celliers, Luiz Da Silva, Michael Glinsky, Richard London, Duncan Maitland, Dennis Matthews, Peter Krulevich, Abraham Lee

Publication number: 20020045890Abstract: This invention is a catheter-based device for generating an ultrasound excitation in biological tissue. Pulsed laser light is guided through an optical fiber to provide the energy for producing the acoustic vibrations. The optical energy is deposited in a water-based absorbing fluid, e.g. saline, thrombolytic agent, blood or thrombus, and generates an acoustic impulse in the fluid through thermoelastic and/or thermodynamic mechanisms. By pulsing the laser at a repetition rate (which may vary from 10 Hz to 100 kHz) an ultrasonic radiation field can be established locally in the medium. This method of producing ultrasonic vibrations can be used in vivo for the treatment of stroke-related conditions in humans, particularly for dissolving thrombus or treating vasospasm.Type: ApplicationFiled: September 10, 2001Publication date: April 18, 2002Applicant: The Regents of the university o f CaliforniaInventors: Peter Celliers, Luiz Da Silva, Michael Glinsky, Richard London, Ducan Mailland, Dennis Matthews, Joseph P.
