AI Technical Summary

Benefits of technology

Enables effective drainage of exudates while keeping the wound closed and isolated from contaminants, reducing the risk of infection and pressure buildup.

Problems solved by technology

Skin closure devices and dressings having porated or porous or apertured tape structure can release the pressure of wound exudates and provide for drainage, however these systems will also leave the incision and wound open to ingress of contaminates through the pores or apertures, potentially resulting in infection.

Embodiment Construction

[0023]According to embodiments of the present invention, self-forming drainage channels are provided to remove exudates and allow drainage from the wound or surgical incision towards the periphery of the skin closure system.

[0024]Referring now to FIGS. 1a-e, embodiments of skin closure system device 10 are shown in a schematic view from a lower side 23, with device 10 comprising a thin, flat, flexible porous tape 20, (depicted as a mesh in all Figs.) having length L and width W and elongated along longitudinal axis 21, with upper side 22 (not visible in views of FIG. 1 but visible for instance in FIG. 5) and lower or wound facing side 23. Tape 20 comprises a porous tape having perforations or micro-holes throughout and can be a woven, non-woven, extruded, punched, perforated, molded, etc. substrate. Preferably tape 20 is a mesh and coated and / or impregnated with an initiator or accelerator of polymerization.

[0025]On lower side 23, which is the tissue or skin facing side of device 10...

Abstract

A device for application onto wounds with a liquid rapidly polymerizable adhesive for forming skin closure systems, comprising a thin flexible flat porous tape, preferably a mesh, elongated along a longitudinal axis and having a lower side or wound-facing side and an opposing upper side, a periphery, and central portion in immediate vicinity of the axis; said tape coated or impregnated with an initiator or accelerator of polymerization; said tape having a plurality of elongated traces of soluble pressure sensitive adhesive (PSA) disposed on the wound-facing side; said traces covering from about 3% to about 50% of area of said tape and extending from the periphery to the central portion of said tape.

Description

[0001]The present disclosure relates to skin closure devices applied over a surgical incision and preferably secured by a polymerizable adhesive, with the devices capable of forming drainage channels for removal of wound exudates.BACKGROUND[0002]A number of devices and methods exist for closing skin or tissue having a surgical incision, opening, cut, wound, or dissection. With these devices, skin or tissue parts separated by the incision are approximated or brought into close proximity forming as narrow a gap as possible in the area of the surgical incision or cut, and then covered by an adhesively attached tape which holds the skin or tissue in closed apposed arrangement until wound healing occurs after which the tape is removed.[0003]Commercially available DERMABOND® PRINEO® Skin Closure System comprises a mesh having a pressure sensitive adhesive and a polymerization initiator disposed on the mesh. The mesh is applied onto the skin over a wound, and a polymerizable cyanoacrylate-...
