| 20100010482 | Enhanced Photodynamic Therapy Treatment and Instrument - A device and method for tumor destruction by photodynamic therapy (PDT) is highly effective in that both the tumor cells themselves and the vasculature feeding the tumor are attacked in a single treatment. Local and systemic methods are used for injecting the photosensitizer (PS) into the tumor as well as vasculature. This combination brings about cellular and vascular destruction more effectively. In the first step, an initial PS dosage is administered locally to the tumor and allowed to achieve near-optimal tumor penetration. A second PS dosage is then administered systemically at a predetermined time after the first dosage and allowed to penetrate the tumor's vascular system for a period of time sufficient to produce a relatively high or otherwise predetermined concentration of PS in the vasculature. A relatively low dosage (mg/kg of PS to body weight) of photosensitizer is used for systemic administration; one advantage of this relatively low dosage is that it may help to help reduce skin photosensitivity. The tumor is then irradiated with a wavelength suitable to activate the first PS, followed by irradiation of the tumor vasculature with a wavelength suitable to activate the second PS. One advantage of the currently preferred embodiment is that both the tumor cells, and the associated vasculature, call be damaged to effectively destroy the tumor in a single treatment. This is achieved using one or two, relatively low photosensitizer dosage, in comparison to prior art dosage. Destruction of the vasculature terminates or otherwise substantially reduces the supply of blood to the tumor, thereby causing the death of any remaining tumor cells and preventing tumor regrowth. The device irradiates the treatment site with more than one wavelength and provides the ability to monitor PS concentration and manually or automatically control the timing of irradiation to activate one or more PSs in sequence or nearly simultaneously. | 01-14-2010 |

| 20130310819 | LASER PLASMA MODULATOR SYSTEM FOR ENDOSCOPY AND ENDOCAVITARY SURGERY - An improved system for safe and efficient generation of plasmas and vapors bubbles with continuous wave radiations and low levels of power densities, sufficient to treat medical pathologies and to avoid the creation damage to healthy tissue is provided. Transmission means in different configurations are used to achieve a high absorption in water, which is able to initiate plasma with low levels of power density. Once plasma and vapor bubbles are formed, they absorb other wavelengths in addition to the one that initiated it. Other wavelengths, more efficiently generated by diodes or diode pumped lasers, are added into the beam to improve treatment efficiency. This modulated plasma produces fast tissue ablation and good hemostasis effect with minimal overheating of remaining tissue. After plasma and high-energy vapors are generated, only laser radiation that passes through the plasma bubble directly interacts with soft tissues. | 11-21-2013 |
| 20130338651 | NON-INVASIVE LASER VASECTOMY - The present invention presents novel methods for performing noninvasive vasectomies in animals, including humans, and vasectomy clamps for use in such procedures.
