Patent number: 10047331Abstract: A tray (100; 400; 500; 600) for accommodating a cell culture (101), such as an embryo, for use during culturing thereof and for optical monitoring of the cell culture, e.g. during in vitro fertilization comprises a carrier structure (104;404;504;604) defining at least one accommodating zone (102; 402; 502; 602) for accommodating the cell culture. At least one focal lens (110; 410; 510; 610), notably a numerical aperture increasing lens is integrally formed with the carrier structure to facilitate monitoring of the cell culture through the carrier structure. A diameter of the focal lens may exceed a diameter of the at least one accommodating zone. The focal lens may be integrally molded with the carrier structure from a thermoplastic material.Type: GrantFiled: March 13, 2014Date of Patent: August 14, 2018Assignee: UNISENSE FERTILITECH A/SInventors: Jonas Lerche Hansen, Niels B.

Publication number: 20150169842Abstract: Methods for determining a development potential for an embryo, for example an in vitro incubating human embryo, and apparatus for implementing such methods are described. In some examples a method comprises obtaining values for a plurality of morphokinetic characteristics relating to the development of an embryo during an observation period, for example characteristics relating to the temporal or morphological development of the embryo. A value for a continuous variable is determined by combining differences between the obtained values for these characteristics and corresponding reference values in a predefined manner. The reference values may, for example, be determined from values for the plurality of characteristics obtained for at least one reference embryo of known development potential. A development potential for the embryo is then established based on the determined value for the continuous variable.Type: ApplicationFiled: June 25, 2013Publication date: June 18, 2015Inventors: Søren Porsgaard, Mette Lægdsmand, Inge Errebo Agerholm
