20080249519 | METHOD AND APPARATUS FOR APPLYING ENERGY TO BIOLOGICAL TISSUE INCLUDING THE USE OF TUMESCENT TISSUE COMPRESSION - An electrode catheter is introduced into a hollow anatomical structure, such as a vein, and is positioned at a treatment site within the structure. Tumescent fluid is injected into the tissue surrounding the treatment site to produce tumescence of the surrounding tissue which then compresses the vein. The solution may include an anesthetic, and may further include a vasoconstrictive drug that shrinks blood vessels. The tumescent swelling in the surrounding tissue causes the hollow anatomical structure to become compressed, thereby exsanguinating the treatment site. Energy is applied by an electrode catheter in apposition with the vein wall to create a heating effect. The heating effect causes the hollow anatomical structure to become molded and durably assume the compressed dimensions caused by the tumescent technique. The electrode catheter can be moved within the structure so as to apply energy to a large section of the hollow anatomic structure. In a further aspect, the location of the electrodes is determined by impedance monitoring. Also, temperature sensors at the treatment site are averaged to determine the site temperature. | 10-09-2008 |

20090111046 | Direct laser and ultraviolet lithography of porous silicon photonic crystal devices - We have developed a simple method to locally change the optical properties of porous silicon multilayers and photonic crystal architectures. This technique allows for the direct photolithography of porous silicon multilayers, heterostructures, and photonic crystals. The procedure controls the local oxidation within the porous silicon layers via ultraviolet radiation or via high intensity laser beam (λ=532.8 nm) exposure. Subsequently, immersion of the non-irradiated and irradiated regions of the porous silicon heterostructures within an alcohol solvent (for example, methanol and ethanol) induces either a marked degradation or no degradation, respectively, in the optical properties of the material. This direct, optical lithographic technique may have significant use in the production of silicon-based optical and opto-electronic devices for laser, optical computation, telecommunications, and other applications. Potential devices include patternable porous silicon waveguides, optical filter, optical switches, and photonic band-gap structures. | 04-30-2009 |
