Abstract
A device for assisting wound closure in a surgical procedure in the form of a silicon rubber suture mat (1,3) and having a front region (2) of generally lenticular shape and an integral narrower tail region (3), the sides (3') of which are mutually biconcave with respect to the biconvex sides (2') of the front region (2) and are continuously curved therewith. When closing a wound, the front region (2) is used to cover, protect and retain the internal organs by being tucked under adjacent tissue, with the tail region (3) protruding from the wound. After the wound has been almost completely closed, the mat, due to its shape and inherent flexibility may be smoothly removed through a small remaining wound aperture (11) prior to final closure.
