Abstract: The present invention relates to a composition for a biodegradable fiber and a biodegradable fiber manufactured using same. In detail, according to an embodiment of the present invention, the composition for biodegradable fibers contains a polyhydroxyalkanoate (PHA) resin bearing 4-hydroxybutyrate (4-HB) repeating units and specifically a first PHA resin and/or a second PHA resin, each bearing 4-HB repeating units and meets a degradation temperature (Td 5% weight loss) of 220° C. or higher as measured by a thermal gravimetric analyzer. Thus, the composition is eco-friendly with excellent biodegradability and biocompatibility and can be used to easily manufacture biodegradable fibers having excellent properties.

Abstract: One embodiment of the present invention provides a breast implant comprising: a filler material comprising two or more types of silicone gel, having different cohesive strengths; and a silicone shell housing the filler material.

Abstract: Disclosed is an artificial implant comprising: a silicone shell; and a filler filling the interior of the shell, wherein at least a portion of the shell is a rupture-prevention part comprising two or more silicone layers and one or more reinforcing material layers interposed therebetween.

Abstract: Disclosed are an artificial implant and a method for manufacturing same, the artificial implant comprising: a silicone shell consisting of an upper portion, a lower portion, and a side portion; and a filler injected into the silicone shell, wherein the silicone shell includes at least one silicone layer and at least one reinforcing layer, the reinforcing layer being provided on at least a portion of the lower portion and the side portion of the silicone shell, or the silicone shell includes a layered structure having a step.
