Abstract: This invention is a circumferential ablation device assembly which is adapted to forming a circumferential conduction block in a pulmonary vein. The assembly includes a circumferential ablation element which is adapted to ablate a circumferential region of tissue along a pulmonary vein wall which circumscribes the pulmonary vein lumen, thereby transecting the electrical conductivity of the pulmonary vein against conduction along its longitudinal axis and into the left atrium. The circumferential ablation element includes an expandable member with a working length that is adjustable from a radially collapsed position to a radially expanded position. An equatorial band circumscribes the outer surface of the working length and is adapted to ablate tissue adjacent thereto when actuated by an ablation actuator.

Abstract: This present invention identifies mutations in several androgen-metabolic genes (SRD5A2, CYP17, HSD3B2, and HSD17B3) and methods of using such mutations in the diagnosis and treatment of inheritable prostate cancer susceptibility. Isolation of genomic DNA of various racial/ethnic populations followed by SSCP scanning and direct PCR sequencing of the aberrant SSCP (single-strand conformation dependent DNA polymorphism) patterns allows for identification of the disclosed polymorphisms. Screening for the disclosed mutations establishes a differential distribution among various racial/ethnic groups as well as altered in vivo enzyme activity that parallels prostate cancer risk.

Abstract: A Time Division Duplex (TDD) wireless system utilizes an identical TDD IC engine in both base station and remote stations. In the base station the clock input to the TDD IC is halted once in the middle of each time slice to provide a central guard band between transmit and receive portions that determines the maximum range of the system. At the remote stations clock halts are programmed and utilized to provide guard bands to position transmit and receive portions in each time slice to accommodate propagation delay based on separation of a remote station from the base station. In a preferred embodiment the remote stations determine range to the base and a controller programs clock halts based on the range finding. In one aspect a TDD IC engine is used with a minimum fixed central guard band and a time slice of a first duration at a first clock frequency. Clock frequency is increased and the clock halted to provide increased range at the same time slice duration.
