Surgical incision and closure apparatus with integrated force distribution
First Claim
1. An incision closure appliance comprising:
- a base including a left panel and a right panel, each panel having a tissue adherent lower surface, an upper surface, a longitudinal axis, an inner edge, and an outer edge;
left and right force distribution structures coupled to the left and right panels, respectively, wherein each force distribution structure comprises an axial spine disposed substantially parallel to the longitudinal axis of the left or right panel and a plurality of lateral supports extending laterally from the axial spine and disposed substantially perpendicularly to the longitudinal axis of the left or right panel, wherein the axial spine and the plurality of lateral supports are integral with one another, wherein the lateral supports are axially separate and spaced apart from one another, wherein the force distribution structures are configured to allow the inner edges of the panels to expand while restraining expansion of the outer edges of the panels, and wherein the axial spine and lateral supports are configured to preserve dimensional stability of the panels when the panels are deformed; and
a closure assembly securable to the left and right panels to draw the inner edges of the panels together, wherein the closure assembly comprises one or more lateral ties, each lateral tie having a fixed end fixedly coupled to one of the left or right force distribution structures and a free end opposite the fixed end, the free end being adjustably coupled to the opposing left or right force distribution structure.

Abstract
Apparatus for closing a surgical incision comprise a base having left and right panels, a force distribution structure coupled to each panel, and a closure component which releasably attaches to the force distribution structure to draw the inner edges of the panels together in order to close adhered tissue edges. The force distribution structures allow the inner edges of the panels to expand while restraining expansion of the outer edges of the panels and limiting elongation of the lateral dimension of the panels. The incision closure appliance may be placed on skin or other tissue prior to forming the incision to be available to close said incision at the end of the surgical procedure.
