Abstract
A surgical suture is described which consists of a monofilament core and a braided sheath surrounding the core. The sheath and the core are temporarily secured together at one end so that the core acts as a stiffener for the sheath during the surgical procedure. After the core and sheath are detached, the core is removed from the sheath and discarded, whereupon the sheath becomes flexible and easy to tie into a secure knot.
