  • Patent number: 8968382
    Abstract: A device comprising a single closed loop of elastic filament configurable between (i) a first configuration for movement along a blood vessel; and (ii) a second configuration for lodging within a blood vessel, the second configuration providing a single flow-restricting face sized and configured to cover the mouth of the aneurysm and obstruct blood flow to the aneurysm while permitting substantially normal blood flow through the blood vessel, with the degree of obstruction at the mouth of the aneurysm being such that the aneurysm thromboses when the face is positioned over the aneurysm, the flow-restricting face comprising a plurality of lengths of the closed loop of filament disposed in close proximity to one another in a switchback configuration, and at least one leg for holding the flow-restricting face adjacent the mouth of the aneurysm, the leg configured so as to maintain substantially normal blood flow through the blood vessel.

  • Publication number: 20050003350
    Abstract: Methods are provided for amplifying regions of the HIV pol gene amplifying double-stranded nucleic acid template derived from HIV tube RT-PCR with novel PCR primers to produce amplified target sequences. Methods are also provided for analyzing the nucleotide sequence of these amplified targets using novel sequencing primers and the data is analyzed. The determined nucleotide sequence can be compared to the sequence of known drug resistance mutations in the HIV pot gene to determine the viral genotype.

  • Patent number: 6103465
    Abstract: A method for typing HLA class 1 genes. The method entails first contacting a sample DNA with first and second amplification primers, wherein the first and second primers are each at least partially located in an exonic region. Next, using the first and second primers, a target sequence is amplified by the PCR to form an amplicon of the target sequence. Finally, the amplicon is detected with a sequence-specific detection means, e.g., DNA sequencing. The invention also includes specific amplification primers, specific sequencing primers, and kits especially adapted for use with the above HLA typing method.
