Abstract: The invention concerns coating composition comprising hydrophobic polymer for use as a photoreactive basecoat for a medical device or implant comprising a polymer made from monomers comprising: (a) 1 to 12 mol % of at least one photoactive monomer that is a hydrogen atom abstracter and (b) 99 to 88 mol % of one or more of acrylamides, methacrylamides, acrylates, methacrylates, and N-vinylpyrrolidone; wherein the polymer has a glass transition temperature (Tg) of less than 40° C.
Abstract: Methods, systems and apparatus for preparing sperm for ICSI by combining selective enrichment benefits of sperm gradient preparation, sperm swim-up preparation and hyaluronan-binding for selection of mature sperm into a single processing unit. The single processing unit of the invention reduces operator labor steps and time, is efficient, easy to use, offers quick processing time and provides highly motile, mature and specific individual sperm that retain desired sperm characteristics selected by each individual selection principal that are ready for capture and use in ICSI.
