Mesh dispenser

Abstract

A dispensing device configured to operate with an adhesive backed mesh and backing film for tissue bonding is disclosed. The dispensing device provides for low-friction, low force pay-out of a desired length of an adhesive backed mesh to a wound site. The device prevents or eliminates distortion of the mesh prior to application to the wound sites and includes means for reducing or eliminating binding during use. The dispensing device is configured to operate in a “forward” mode (substrate to which mesh is applied passes beneath applicator after mesh is applied) to provide essentially an unobstructed view of the wound site during use.
