Barbed suture design and manufacture

These geometrical designs may be inspired by nature, such as the arthro-podic suture (Whitaker et al., 2005).

Another method for creating barbs on suture involves a cutting apparatus which cuts barbs on the tensioned filament between delivery and feed rollers (Rg. 13.20) (Trull et al., 2004). Die embossing, cutting or chemical 

Barbs can be formed in a spiral around the monofilament by inserting twist into the monofilament prior to creating the barbs. When returned to a straightened and relaxed state the barbs then form a spiral around the monofilament suture (Buncke, 1999).
