Patent number: 11975136Abstract: A system for aseptic collection of mammalian amniotic fluid. The system includes a cannula having an attachment end and external end. The attachment end provides a concentric opening to a hollow chamber disposed about a central passage. The hollow chamber has a port disposed adjacent to the external end permitting at least a partial suction to be established within the hollow chamber, the attachment end thereby suctionally attached to a surface when the attachment end is disposed upon the surface. The central passage provides access to a central portion of the surface surrounded by the concentric opening of the hollow chamber. An extraction needle is disposed within the central passage of the cannula and presented to the central portion of the surface.

Patent number: 7799685Abstract: In a technique for fabricating an integrated circuit to include an active device structure which supports an electrical interconnect structure, a photoresist layer is used prior to forming an electrical interconnect structure on the active device structure. The photoresist and related residues are removed by exposing the photoresist and exposed regions of the active device structure to one or more reactive species that are generated using a gas mixture including hydrogen gas, as a predominant source of the reactive species, in a plasma source such that the photoresist and residues are continuously exposed to hydrogen-based reactive species. An associated system architecture is described which provides for a substantial flow of hydrogen gas in the process chamber.Type: GrantFiled: October 4, 2004Date of Patent: September 21, 2010Assignee: Mattson Technology, Inc.Inventors: Stephen E.
