  • Publication number: 20230193153
    Abstract: The present invention relates to a method of for extracting oil from an oil-containing phospholipid composition, comprising the steps of: (a) Providing the oil-containing phospholipid composition, said composition comprising phospholipids and oil, the oil being in an amount of between and 80 wt % relative to the total weight of the oil composition; (b) Admixing water with the oil-containing phospholipid composition to obtain an aqueous composition, wherein the weight ratio of composition to water is between 6.0:1.0 and 1.3:1.0; (c) Separating the aqueous composition into an oil-rich fraction and an oil-depleted fraction, the oil-depleted fraction comprising water and phospholipids; and (d) removing the separated oil-rich fraction to obtain an aqueous, oil-depleted fraction comprising phospholipids; (e) optionally drying the aqueous, oil-depleted fraction to obtain a dried oil-depleted fraction comprising phospholipids.

  • Patent number: 11596709
    Abstract: Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.
