Claims (15)

  1. An apparatus, comprising: (a) a cannula defining a lumen, wherein the cannula is configured to operatively couple with a suction source to thereby establish fluid communication between the suction source and the lumen, wherein the cannula further comprises a distal portion defining at least one aperture, wherein the at least one aperture is in fluid communication with the lumen and an exterior surface of the distal portion; and (b) a wound closure device dimensioned to cover a wound in skin, wherein the wound closure device is configured to receive a layer of topical adhesive to thereby adhere to the skin and form a microbial barrier over the wound, wherein the wound closure device comprises a cannula housing defining a channel dimensioned to receive the distal portion of the cannula, wherein the cannula is configured to be inserted within the cannula housing to thereby provide fluid communication between the suction source and the wound after formation of the microbial barrier; wherein the wound closure device further comprises a textile mesh, wherein the textile mesh comprises the cannula housing.
  2. The apparatus of claim 1, wherein the wound closure device further comprises a pressure sensitive adhesive configured to temporarily attach the textile mesh to the wound.
  3. The apparatus of claim 2, wherein the wound closure device further comprises a backing removably covering the pressure sensitive adhesive.
  4. The apparatus of any preceding claim, wherein the distal portion of the cannula further comprises a closed distal tip.
  5. The apparatus of any preceding claim, wherein the distal portion of the cannula further comprises at least one barb.
  6. The apparatus of claim 5, wherein the at least one barb comprises a longitudinal array of barbs.
  7. The apparatus of claim 6, wherein the longitudinal array of barbs extends away from the at least one aperture of the distal portion of the cannula.
  8. The apparatus of any preceding claim, wherein the wound closure device comprises a first textile mesh and a second textile mesh, wherein the distal portion of the cannula is interposed between the first textile mesh and the second textile mesh.
  9. The apparatus of claim 8, wherein the second textile mesh comprises a pressure sensitive adhesive, wherein the cannula is attached to the pressure sensitive adhesive.
  10. The apparatus of any preceding claim, wherein the wound closure device comprises a substantially rectangular shape.
  11. The apparatus of any preceding claim, wherein the cannula housing comprises an open proximal end and a closed distal end.
  12. The apparatus of claim 11, wherein the open proximal end is located at a first peripheral location of the wound closure device.
  13. The apparatus of claim 11 or 12, wherein the distal end is located at a second peripheral location of the wound closure device.
  14. The apparatus of any preceding claim, wherein the cannula housing comprises a proximal end and distal end, wherein the cannula housing is tapered such that the proximal end is wider than the distal end.
  15. The apparatus of any preceding claim, wherein the proximal end and the distal end are both located within the peripheral edges of the wound closure device.

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. US2007055205 describes a protective device having a substantially rigid casing for placement on a patient's skin, wherein the casing has a hollow interior facing the patient's skin and a lip. US2013102945 describes a light-weight, semi-rigid wound shield that is said to protect wounds and intradermal therapy ports from impacts between therapy sessions. US2010042058 describes a drainage system that is said to extract fistula-produced discharge, or other bodily fluids, from an injury, such as a burn, laceration, or contusion. US2013231619 describes a wound management device comprising at least one wall element of flexible sheet material, the device being securable to skin around a wound site to define a space wherein the wound is accessible; and a connector element held to the at least one wall element and affording at least one passage for external communication with the space; wherein the connector element includes at least one formation through which the or a passage extends, for engagement by a member for fluid supply to or removal from the space. 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.
