Abstract
A gravity drainage cord formed by braiding a plurality of strands of silk of the type used for surgical sutures, and fitted loosely, in the median region, in a tubular sheath made of a material such as silicone which is adapted to facilitate sliding with respect to tissue, increases biocompatibility and allows optional coupling to mechanical aspiration units.
