Patent number: 7169355Abstract: The invention includes a heating apparatus for biological samples. The heating apparatus of the present invention includes a cover, a sample block having a plurality of openings in a top portion thereof for receiving a sample well tray having a plurality of sample wells, and an urging mechanism. The urging mechanism is positionable between the sample block and the sample well tray to urge the sample well tray away from the sample block when the cover is moved from a closed position toward an open position. The cover imparts a downward force on the top of the sample well tray to press the sample wells into the openings of the sample block when the heated cover is moved toward a closed position. The urging mechanism imparts an upward force on the sample well tray. The downward force imparted by the heated cover is sufficient to retain the sample well tray against the sample block when the cover is in the closed position.Type: GrantFiled: February 2, 2000Date of Patent: January 30, 2007Assignee: Applera CorporationInventors: Hon Siu Shin, Jew Kwee Ngui, Adrian Fawcett, Kenneth P.

Patent number: 7015031Abstract: A specimen culturing system and method is employed to culture biological specimens, preferably embryos. The embryos are cultured in an incubator in separate culturing sites, such as wells, which can each hold an embryo container, such as a Petrie dish, that contains one or more of the embryos. The culturing wells are disposed in one or more shelves in the incubator. The culturing containers are formed from a transparent material such as tempered glass. Each of the wells are provided with embryo development-monitoring adjuncts. The development-monitoring adjuncts are preferably embryo-imaging devices and sound-monitoring devices. The system includes image and sound recording components which can record periodic images of the embryos during the culturing cycle; and can record sounds emanating from the specimens. The embryo-imaging devices can include CCD imaging devices which are connected to image viewing and recording adjuncts by means of electrical connections.Type: GrantFiled: January 24, 2002Date of Patent: March 21, 2006Assignee: Genx International, Inc.Inventors: Michael D.

Patent number: 6921660Abstract: The present invention discloses a device for monitoring chemotaxis or chemoinvasion including a housing comprising: a support member and a top member, the top member mounted to the support member by being placed in substantially fluid-tight conformal contact with the support member. The support member and the top member are configured such that they together define a discrete chamber adapted to allow a monitoring of chemotaxis or chemoinvasion therein. The discrete chamber includes a first well region including at least one first well, the at least one first well configured to received a test agent therein; a second well region including at least one second well, the at least one second well configured to receive a sample comprising cells therein; and a channel region including at least one channel connecting the first well region and the second well region with one another. The second well region is preferably horizontally offset with respect to the first well region in a test orientation of the device.Type: GrantFiled: March 15, 2002Date of Patent: July 26, 2005Assignee: Surface Logix, Inc.Inventors: Gregory L.
