Provided is a medical suture thread which is less likely to remain curled or is easily uncurled from a curled state. The medical suture thread 100 includes a core thread 110 and an outer thread 120. The core thread 110 includes multiple twisted ultrafine threads 111, and is arranged at a center portion of the medical suture thread 100. In the ultrafine thread 111, an inner-filament cover layer 112 made of 2-methacryloyloxyethyl phosphorylcholine (MPC) is formed on an outer surface of a filament 111a. The outer thread 120 is formed to be braided with multiple ultrafine threads 121, and covers an outer surface of the core thread 110. In the ultrafine thread 121, an outer-filament cover layer 122 made of MPC is formed on an outer surface of a filament 121a. The inner-filament cover layer 112 and the outer-filament cover layer 122 are respectively formed on the outer surfaces of the filaments 111a, 121a within a weight range of equal to or greater than 0.05% and less than 0.3% with respect to the total weight of each of the filaments 111a, 121a, respectively.

Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability and are readily applied in coating processes a low temperatures that do not deform the device. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.

Technologies for fibers with nanotechnology is disclosed. In the illustrative embodiment, a preform is 3D printed with one or more sacrificial cores and one or more hollow channels. The preform is drawn into a fiber, and one or more metal core(s) is inserted into the hollow channel during the fiber draw. The fiber is then heated, breaking up the sacrificial cores into balls through capillary action. The fiber can be etched, exposing the balls made up of the sacrificial cores. The balls can be selectively etched, exposing the metal core(s) of the fiber. Additional embodiments are disclosed.

The present application relates to fibers having a diameter of 1 nm to 10,000 nm, of one or more biocompatible polymers, wherein the polymers have a backbone which includes a positively charged component from a zwitterionic moiety. Additionally, this application discloses an implantable therapeutic delivery system and its method of formation, comprising a housing defining a chamber, wherein said housing is porous and formed from the fibers. Inside of the housing includes a preparation of cells which release a therapeutic agent from the chamber. The implantable therapeutic delivery system can be used in the treatment of diabetes.

A suture for lifting is disclosed. The suture comprises: a medical fiber yarn; fixing parts formed at one side of the fiber yarn and fixable to the skin; and anchor parts protruding on an outer circumference of the fixing parts, wherein the anchor parts are integrally formed with the fiber yarn by a double injection.
