Abstract

A surgical suture system (1, 21, 41) is illustrated and described. The object, namely to permit simple correction of the suture course or of an incorrect position, is achieved by a suture system (1) with a needle-like applicator (2, 22, 42) having a tip (26, 50) in its front end area, with a surgical suture material (4, 24, 44) provided with barbs (6, 7, 28, 29, 47, 48) which, on one side, preferably point in one direction of action from a reference point (8, 30, 49) and, on the other side, point in the opposite direction of action from the reference point (8, 30, 49) and are designed to block a movement of body tissue (12) away from the reference point (8, 30, 49), and with a sheath (3, 23, 43) whose front end area starts from the rear end area of the applicator (2, 22, 42) and which surrounds the surgical suture material (4, 24, 44).
