Claims (15)

  1. A system, comprising: (i) a surgical mesh including an upper side and a lower side, the upper side including a visual indicia pattern that extends longitudinally along the upper side, the lower side being configured to adhere to a section of skin of a patient that surrounds a wound; and (ii) a topical skin adhesive configured to be applied to the upper side of the surgical mesh based on the visual indicia pattern, the topical skin adhesive being configured to cure within the surgical mesh to thereby form a protective layer over the wound.
  2. The system of claim 1, wherein the surgical mesh is configured to adhere to opposing sides of the wound of the patient to thereby approximate the opposing sides.
  3. The system of claim 1 or 2, further comprising a spreader configured to spread the topical skin adhesive across the upper side.
  4. The system of any preceding claim, wherein the surgical mesh includes a first longitudinal end, a second longitudinal end, and a longitudinal centerline extending therebetween, wherein a portion of the visual indicia pattern intersects the longitudinal centerline or extends directly over top of and along the longitudinal centerline.
  5. The system of claim 4, wherein the visual indicia pattern extends from the first longitudinal end to the second longitudinal end.
  6. The system of any preceding claim, wherein the visual indicia pattern includes a plurality of discrete pattern segments that are disconnected from one another.
  7. The system of any preceding claim, wherein at least a portion of the visual indicia pattern extends along an arcuate path, optionally wherein the visual indicia pattern includes a sinusoidal wave.
  8. The system of any preceding claim, wherein the visual indicia pattern includes a "T" shape.
  9. The system of any of claims 4 to 8, wherein the visual indicia pattern includes a first line segment that transversely intersects the longitudinal centerline at the first longitudinal end, and a second line segment that extends directly over top of and along the longitudinal centerline from the first longitudinal end to the second longitudinal end.
  10. The system of any preceding claim, wherein the visual indicia pattern includes a series of parallel lines.
  11. The system of claim 10, wherein at least some of the parallel lines extend parallel to the longitudinal centerline.
  12. The system of claim 10, wherein at least some of the parallel lines extend transversely to the longitudinal centerline.
  13. The system of any preceding claim, wherein the surgical mesh includes a pressure sensitive adhesive along the lower side.
  14. The system of any preceding claim, wherein the surgical mesh includes a plurality of time-based indicators collectively configured to visually indicate a timeline for applying topical skin adhesive to the upper side of the surgical mesh relative to the visual indicia pattern.
  15. The system of claim 1, wherein: (i) the lower side includes a pressure sensitive adhesive configured to adhere to a section of skin of a patient that surrounds a wound; (ii) the protective layer is a liquid-resistant layer; and (iii) the system further comprises a spreader configured to spread the applied topical skin adhesive across the upper side prior to curing.

Description

BACKGROUND A wound closure system (also referred to as a skin closure system) may be used at the conclusion of a surgical procedure on a patient to close a wound (e.g., a surgical incision) that was formed in the patient's skin for accessing a target anatomical structure. By way of example, wound closure systems may include components such as sutures, substrates, and/or liquid topical skin adhesives that are applied by a surgeon to approximate the edges of the wound and, in some cases, form a stable and protective layer over the wound that promotes efficient healing. In some instances, one or more components of the applied wound closure system may be absorbed by the patient during the healing process. Following healing of the wound, remaining components of the wound closure system may be removed from the skin by a surgeon, and/or they may automatically separate from the skin such that they may be discarded by the patient. US 2014148640 describes an implantable article and method for treating pelvic floor disorders such as vaginal vault prolapse. A surgical kit that is said to be useful for performing a surgical procedure such as a sacral colpopexy is also described. US 2011082478 describes a suture kit including a plurality of flexible strands of suture, each of the strands of suture having one or more suture markings indicative of a suture orientation and a mesh material configured to enable the strands of suture to be passed therethrough, wherein at least one quadrant/section of the mesh material has one or more mesh markings indicative of a mesh material orientation. The one or more suture markings include visual indicators and the one or more mesh markings include visual indicators, the suture visual indicators corresponding to the mesh visual indicators for indicating correct orientation of the mesh material with respect to tissue of a subject. US 8097008 describes an apparatus for the laparoscopic deployment and positioning of surgical materials, such as mesh. The mesh is applied by at least one extension arm which radiates from a central shaft. Alternate embodiments employ simultaneously and/or individually extended rigid arms, and simultaneously deployed resilient arms. Various methods are also disclosed for attaching the mesh to the abdominal wall once it is deployed by the extension arms. Illustrative attaching methods include staples, low viscosity adhesives, and electro-cauterization. While various wound closure systems and associated components and methods have been made and used, it is believed that no one prior to the inventors has made or used the invention described in the appended claims.
