Wound closure system having microcannulaic pathways
An apparatus includes a cannula that can establish fluid communication with a suction source, and a wound closure path dimensioned to cover a wound in skin. The wound closure patch can receive a topical adhesive to adhere to the skin and form a microbial barrier over the wound. The wound closure patch defines a channel. The wound closure patch includes a top surface, a bottom surface defining at least one channel interposed between the top surface and the bottom surface, and a fluid coupling section in fluid communication with the channel. The fluid coupling section can couple with the cannula to thereby establish fluid communication between the cannula, the channel, and the at least one opening defined by the bottom surface.
