To provide active sutures that can be used if necessary to suture the wound also delivery to the tissues surrounding the wound of [challenges] therapeutic fluid. It can A1 The present invention enables the delivery of drug-containing solution having an amount of drug efficacy, to control the fluid delivery speed at high level. Proximal and a braided suture having an outer diameter and a distal end, an active suture of the present invention, the outer of the braided suture and the proximal and distal coaxial with at least part of said braided suture comprising the at least one passage having a diameter smaller than the diameter, the proximal of the braided suture and the distal end of one passageway is positioned between the distal end at least. [Selection Figure] Figure 1a【課題】治療液の創傷周囲の組織への送達、また創傷縫合にも必要に応じて使用できる能動縫合糸を提供する。【解決手段】本発明は薬効を有する量の薬物含有溶液の送達を可能にし、高レベルで液体送達速度を制御することができる。本発明の能動縫合糸は、近位および遠位端と外径とを有する編組縫合糸と、前記編組縫合糸の少なくとも一部と同軸で近位および遠位端と前記編組縫合糸の前記外径よりも小さい直径を有する少なくとも一つの通路とを具備し、前記少なくとも一つの通路の遠位端は前記編組縫合糸の前記近位および遠位端の間に配置されている。【選択図】図1a
