The present invention relates to a monofilament suture and a preparation method thereof, more specifically, to a novel monofilament suture wherein two polymers having identical inherent properties are spun to have a cross-sectional structure of conjugated filaments, and said cross-section has interfaces between the spun polymers. The interfaces form a discontinuous cross-section along the radial direction and are distributed continuously along the fiber axis direction, thereby offering improved knot security and applicability to a variety of medical materials, and a preparation method thereof.

Monofilament suture and preparation method thereof

The present invention relates to an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block with a terminal hydroxyl group wherein the terminal hydroxyl group of the hydrophobic bock is substituted with a tocopherol or cholesterol group. It also relates to polymeric compositions capable of forming stable micelles in an aqueous solution, comprising the amphiphilic block copolymer and a polylactic acid derivative wherein one or more ends of the polylactic acid are covalently bound to at least one carboxyl group.

Amphiphilic block copolymer and polymeric composition comprising the same for drug delivery

Polymeric compositions capable of forming stable micelles in an aqueous solution, comprising an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block, and a polylactic acid derivative wherein one end of the polylactic acid is covalently bound to at least one carboxyl group. The carboxyl group of the polylactic acid derivative may be fixed with a di- or tri-valent metal ion, obtained by adding the di- or tri-valent metal ion to the polymeric composition.
