Abstract

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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 245 words
A suture mat for temporary placement in a body to retain and protect body organs during surgical procedures and capable of being withdrawn from the body through a restricted opening therein, said mat comprising a sheet of flexible material comprising: means for retaining a body organ against displacement and for removal from said body through an opening, said means being a thin body of oblong shape having bi-convex lenticular sides and having substantial lateral and longitudinal extent with the lateral extent greater than the opening, said means being uninflatable and of substantially uniform thickness, and elongate means integral with said oblong retaining means extending from and longitudinally of said oblong retaining means for extraction of said retaining means from a body, said elongate extraction means having a lesser lateral extent than said oblong retaining means and a length greater than the lateral extent thereof and having sides are bi-concave with respect to said bi-convex sides, each bi-convex side of said retaining means continuously curving into a respective concave side of said extraction means, said extraction means having an end thereof remote from said retaining means, said retaining means having a rounded end portion opposite said extraction means, the end of said extraction means having a bi-concave curvature which substantially matches the rounded end portion of said retaining means, said suture mat being without a center reinforcing piece and without means for causing said sheet to be in a substantially vertical plane when immersed in water.
Claim 2
Dependent Claim 245 words
A suture mat for temporary placement in a body to retain and protect body organs during surgical procedures and capable of being withdrawn from the body through a restricted opening therein, said mat comprising a sheet of flexible material comprising: means for retaining a body organ against displacement and for removal from said body through an opening, said means being a thin body of oblong shape having bi-convex lenticular sides and having substantial lateral and longitudinal extent with the lateral extent greater than the opening, said means being uninflatable and of substantially uniform thickness, and elongate means integral with said oblong retaining means extending from and longitudinally of said oblong retaining means for extraction of said retaining means from a body, said elongate extraction means having a lesser lateral extent than said oblong retaining means and a length greater than the lateral extent thereof and having sides are bi-concave with respect to said bi-convex sides, each bi-convex side of said retaining means continuously curving into a respective concave side of said extraction means, said extraction means having an end thereof remote from said retaining means, said retaining means having a rounded end portion opposite said extraction means, the end of said extraction means having a bi-concave curvature which substantially matches the rounded end portion of said retaining means, said suture mat being without a center reinforcing piece and without means for causing said sheet to be in a substantially vertical plane when immersed in water.
