Patent number: 10765454Abstract: An oocyte retrieval needle is provided. The needle comprises a first tubular region in fluid communication with a second tubular region. The first tubular region comprises a sharp point leading end configured for insertion into a subject. The second tubular region comprises an open trailing end. The leading and trailing ends form respective opposite ends of the needle. Internal passages of the first and second tubular regions form a continuous open passage extending from the leading end to the trailing end. The first tubular region has an outer diameter which is less than an outer diameter of the second tubular region and the internal passage of the first tubular region has an inner, luminal diameter which is less than an inner diameter of the internal passage of the second tubular region. The oocyte retrieval needle is a double lumen needle.Type: GrantFiled: January 31, 2018Date of Patent: September 8, 2020Assignee: VITROLIFE SWEDEN ABInventor: Urban Hagby

Patent number: 8859280Abstract: A composition and method for in vitro fertilization is provided which uses culture media comprising elevated concentrations of lipoic acid. More specifically, the invention provides culture media for developmental cells having a lipoic acid concentration of 5 ?M to 40 ?M. Culture media that include lipoic acid at concentrations within the identified range are able to provide blastocysts with increased survival, increased cell numbers, increased inner cell masses and/or increased percentage of the total mass made up by the inner cell compared to blastocysts cultured in a control medium.Type: GrantFiled: August 23, 2013Date of Patent: October 14, 2014Assignee: Vitrolife Sweden ABInventors: David K Gardner, Mark G Larman, Donald Linck
