    摘要: 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.

    摘要: A medical device includes a surgical needle, an elongated suture, and an intervening segment. The elongated suture has a first end proximate to the needle and a second end located away from the needle. The elongated suture also includes a plurality of fibers defining a mesh wall between the first and second ends. A plurality of pores extend through the mesh wall, at least some which are in the macroporous size range of greater than 200 microns for facilitating tissue integration when introduced into a body. The intervening segment is disposed between and connected to either or both ends of the elongated suture and the needle. The intervening segment includes one or more fibers of the plurality of fibers and has a cross-sectional dimension smaller than a cross-sectional dimension of the mesh wall such that the intervening segment facilitates indirect attachment of the elongated macroporous mesh suture to the needle.
