Patent number: 6669720Abstract: An apparatus for endovascular repair of aortic aneurysms is disclosed. In one form, the apparatus includes a tube and an anchoring unit that includes a plurality of thin lines. The tube serves as a conduit for blood flow in an aneurysm of an aorta. A first end of the plurality of lines is connected to a first end of the tube. A second end of the plurality of lines is separated by a distance from the first end of the tube for anchoring the apparatus at a location away from the aneurysm.Type: GrantFiled: November 21, 2000Date of Patent: December 30, 2003Inventor: George E. Pierce

Patent number: 6132985Abstract: The present invention describes methods for the detoxification of a mixture of nitrile compounds, or a mixture of nitrile and amide compounds by conversion of the nitrile compound(s) to the corresponding amide or acid compounds using a pure culture of an induced microorganism strain capable of converting a nitrile moiety to an amide or acid moiety. If an amide is formed or is present in the mixture, the amide can be further converted, using the present methods for detoxification, to the corresponding acid. The acid can then, if desired, be further degraded to CO.sub.2, H.sub.2 O and biomass. The induced pure cultures are able to detoxify a mixture of nitriles or a mixture of nitrites and amides which are typically present, in high concentration(s), in nitrile production waste streams.Type: GrantFiled: June 18, 1999Date of Patent: October 17, 2000Assignee: Cytec Technology CorporationInventor: George E.
