Patent number: 8986945Abstract: Provided are methods and compositions for isolating and detecting rare cells from a biological sample containing other types of cells, particularly including debulking that uses a microfabricated filter for filtering samples. The enriched rare cells can be used in a downstream process such as identification, characterization or growth in culture, or in other ways. Also included is a method of determining tumor aggressiveness or the number or proportion of cancer cells in the enriched sample by detecting telomerase activity, nucleic acid or expression after enrichment of rare cells. Also provided is an efficient, rapid method to specifically remove red and white blood cells from a biological sample containing at least one of the cell types, leading to enrichment of rare target cells including circulating tumor (CTC), stromal, mesenchymal, endothelial, fetal, stem, or non-hematopoietic cells et cetera from a blood sample.Type: GrantFiled: August 20, 2007Date of Patent: March 24, 2015Assignee: Aviva Biosciences CorporationInventors: Ping Lin, Andrea Ghetti, Wenge Shi, Mengjia Tang, Gioulnar I.

Patent number: 7255824Abstract: An apparatus for molding a plastic closure includes a male mold assembly including a forming pin and an outer pin sleeve which cooperate with a female mold for defining a mold cavity. To facilitate mechanical stripping of a molded closure from the forming pin, pressurized air is introduced into the molded closure through at least one air passageway which extends axially between the forming pin and pin sleeve. By outwardly expanding and forming the plastic closure during ejection from the forming pin, forces to which the closure is subjected during ejection are significantly reduced, thereby desirably reducing the amount of cooling of the closure that is required during the molding cycle prior to ejection. Significantly increased operating speeds for the compression molding apparatus can thus be achieved.Type: GrantFiled: March 23, 2005Date of Patent: August 14, 2007Assignee: Alcoa Closure Systems InternationalInventors: David Cerny, Ramesh Kamath, Mark Powell, Greg Mishler, Sohail Sadiq, David Oles, Lindsey Abney

Patent number: 5858016Abstract: An aseptic/sterile fluid connection between two containers is formed by radio frequency sealing together portions of transfer regions of two containers. Each transfer region has a layer of a relatively high melt temperature material such as a rubber or elastomer positioned between two outer container walls made of a flexible thermoplastic, for example polyvinyl chloride. The transfer regions are placed in registry, and the radio frequency welding fuses together portions of adjacent container outer walls and forms a fluid opening therethrough.Type: GrantFiled: July 14, 1992Date of Patent: January 12, 1999Assignee: Baxter International Inc.Inventors: David Bacehowski, David Cerny, Dean Glash, Richard Afflerbaugh, Joseph West, Jr.

Patent number: 4957656Abstract: An ultrasonic imaging agent is produced by a continuous sonication processing of an aqueous solution of heat-denaturable biocompatible protein. The solution is carefully preheated to a temperature of incipient protein denaturation without forming insolubilized protein. A gaseous fluid, preferably air, is added to the solution. In the sonication, the air-containing solution is foamed, increasing the formation and concentration of microbubbles, and the solution is further heated to insolubilize a portion of the protein, thereby encapsulating the microbubbles and forming particulate microspheres.Type: GrantFiled: September 14, 1988Date of Patent: September 18, 1990Assignee: Molecular Biosystems, Inc.Inventors: David Cerny, Gary J. Mills, Peter J. Westkaemper
