MEDICAL SUTURE THREAD
Provided is a medical suture thread as a multifilament, which is formed easily bendable and ensuring favorable operability. 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.

SURGICAL SUTURE HAVING EXCELLENT BIOCOMPATIBILITY AND LOW FRICTION, AND METHOD FOR MANUFACTURING SAME
The present invention relates to a surgical suture having excellent biocompatibility and low friction, and to a method for manufacturing same. The suture according to the present invention has excellent biocompatibility and low friction, thereby reducing pain that may occur in a patient during suturing and minimizing the occurrence of inflammation in cells at a suture site, and also has excellent contact properties with cells, thereby capable of being used for various medical and surgical operations.
Sutures with External Filament Containing A Medicant
The present invention is directed to suturing systems having a needle, an elongated flexible suture having a connecting end attached to a said needle and an opposing free end and at least one elongated external beneficial filament that is attached to said needle or attached to said suture at the connecting end. The beneficial filament has a smaller cross-sectional area and lower mechanical strength than the suture and contains a medicant.

High-performance polyethylene multifilament yarn
Processes for making high-performance polyethylene multi-filament yarn are disclosed which include the steps of a) making a solution of ultra-high molar mass polyethylene in a solvent; b) spinning of the solution through a spinplate containing at least 5 spinholes into an air-gap to form fluid filaments, while applying a draw ratio DR.sub.fluid; c) cooling the fluid filaments to form solvent-containing gel filaments; d) removing at least partly the solvent from the filaments; and e) drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DR.sub.solid of at least 4, wherein in step b) each spinhole comprises a contraction zone of specific dimension and a downstream zone of diameter Dn and length Dn with Ln/Dn of from 0 to at most 25, to result in a draw ratio DR.sub.fluid=DR.sub.sp*DR.sub.ag of at least 150, wherein DR.sub.sp is the draw ratio in the spinholes and DR.sub.ag is the draw ratio in the air-gap, with DR.sub.sp being greater than 1 and DR.sub.ag at least 1. High-performance polyethylene multifilament yarn, and semi-finished or end-use products containing said yarn, especially to ropes and ballistic-resistant composites, are also disclosed.

Method for preparing high-functional suture yarn coated with hyaluronate and high-functional suture yarn prepared therefrom
Provided is a method of manufacturing a hyaluronate-coated high-functional suture and a high-functional suture manufactured thereby, and more particularly to a method of manufacturing a high-functional suture and a high-functional suture manufactured thereby, wherein a suture for internal and external surgery derived from a conventional chemical synthetic material is coated with a hyaluronate as a biocompatible material, thus improving biocompatibility, functionality and ease of use. Upon application of the hyaluronate-coated suture of the invention to the human body, the hyaluronate applied on the surface of the suture is rapidly swollen by body fluids and can thus function as a lubricant, thus being convenient to use by a surgical doctor and reducing the pain of a patient and maximizing the functions of skin filling or skin regeneration in the body.
