  • Low-profile ventriculoamniotic shunt for fetal aqueductal stenosis
    Patent number: 10744308
    Abstract: The invention relates to an in-utero ventriculoamniotic shunting device that includes a shunt tube (26) composed of polymer composite and having metallic wire embedded therein, one or more anchors (30) composed of superelastic wire, e.g., thermal shape-set nitinol structures, that are mechanically attached to an exterior surface of the shunt tube (26), and a one-way passive valve (32) composed of a thin polymer membrane. The anchors (30) are effective to prevent migration and dislodgement of the shunting device following its deployment, and the valve (32) is effective to prevent the backflow of amniotic fluid (23).

  • Antibodies directed to angiopoietin-2 and uses thereof
    Publication number: 20060246071
    Abstract: Antibodies directed to the antigen Ang-2 and uses of such antibodies are described. In particular, fully human monoclonal antibodies directed to the antigen Ang-2. Nucleotide sequences encoding, and amino acid sequences comprising, heavy and light chain immunoglobulin molecules, particularly sequences corresponding to contiguous heavy and light chain sequences spanning the framework regions and/or complementarity determining regions (CDR's), specifically from FR1 through FR4 or CDR1 through CDR3. Hybridomas or other cell lines expressing such immunoglobulin molecules and monoclonal antibodies.
