  • Patent number: 8114148
    Abstract: According to an aspect of the present invention, at least one ionic therapeutic agent is delivered from an implantable or insertable medical device that comprises an ion-conductive polymeric region that is disposed on a metallic region. The metallic region is in electrical contact with a dissimilar metallic region, such that a galvanic current is generated by the dissimilar metals when the device is implanted or inserted into a patient. Delivery of the ionic therapeutic agent from the ion-conductive polymeric region may be, for example, either accelerated or retarded by the galvanic current.

  • Patent number: 8057827
    Abstract: Novel methods for the chemical ablation of tissue (e.g. prostatic tissue) are described. These methods include the steps of: (a) providing one or more solid salt dosage forms comprising 50-100% w/w salt; and (b) inserting one or more of such solid salt dosage forms into the tissue. The solid salt dosage forms is optionally inserted into the tissue under real-time ultrasonic observation. An advantage of the present invention is its ability to eliminate toxic byproducts. For example, where NaCl-based solid salt dosage forms are used to effect localized chemical ablation, the concentration is ultimately reduced to the level of normal saline (i.e., about 0.9%) upon absorption by the body of the subject being treated.

  • Patent number: 8049271
    Abstract: A method is provided for forming a power semiconductor device. The method begins by providing a substrate of a second conductivity type and then forming a voltage sustaining region on the substrate. The voltage sustaining region is formed by depositing an epitaxial layer of a first conductivity type on the substrate and forming at least one terraced trench in the epitaxial layer. The terraced trench has a plurality of portions that differ in width to define at least one annular ledge therebetween. A barrier material is deposited along the walls of the trench. A dopant of a second conductivity type is implanted through the barrier material lining the annular ledge and said trench bottom and into adjacent portions of the epitaxial layer. The dopant is diffused to form at least one annular doped region in the epitaxial layer and at least one other region located below the annular doped region.

  • Patent number: 8049956
    Abstract: The present invention relates to an OPCPA apparatus. The OPCPA of the present invention includes an optical pulse stretcher (100) for outputting chirped laser light using odd-order dispersion (third-order dispersion is mainly used). A pump laser (200) outputs pump laser light. An OPA unit (300) receives the pump laser light and the chirped laser light (signal), amplifies the signal using the pump laser light, and generates an idler. An optical signal separation unit (400) separates output light of the OPA unit into the signal, the idler, and remaining light (pump). An optical pulse compressor (600) compensates for pulse chirping caused by odd-order dispersion that is imparted by the optical pulse stretcher, thus temporally compressing the signal and the idler, which overlap each other.
