Abstract

A surgical access device includes a tissue retractor including a flexible body configured to engage tissue surrounding a tissue opening. A plurality of surgical instrument channels is arranged in a central portion of the tissue retractor. Each surgical instrument channel is configured to guide a surgical instrument distally through the surgical access device. At least one needle entrance port is arranged on a proximal portion of the surgical access device. At least one needle exit port is arranged distally of the needle entrance port. The at least one needle entrance port and the at least one needle exit port are configured to cooperate to define a needle channel extending distally through the surgical access device and obliquely relative to a central axis thereof. The needle channel is configured to guide a suture passer needle through the surgical access device and adjacent tissue to facilitate closure of the tissue opening.
