Abstract
Abstract A package for multiple strands of surgical sutures which provides for delivery of individual suture strands. The sutures are aligned into a bundle of substantially parallel strands and the bundle is wound in the form of a coil comprising a series of contiguous, overlapping convolutions, each convolution being laterally displaced from adjacent convolutions and disposed in sequence from one end of the suture to the other. The desired suture coil configuration is conveniently obtained by winding the suture bundle around two vertical winding pins in an upwardly spiraling pattern with successive loops being displaced laterally along the pins. The wound suture is packaged in a suture folder which is adapted to maintain the suture bundle in its wound configuration with one end of the suture bundle extending from the folder whereby individual suture strands may be grasped and withdrawn from the package.
