A suture system configured to place suture in tissue includes a tool and a suture assembly. The tool includes a proximal portion, a distal end spaced apart from the proximal portion by a throat, and a needle that is movable through a needle exit port formed in the proximal portion of the tool to a cavity formed in the distal end of the tool. The suture assembly includes a leader that is insertable into the cavity. The leader has a distal end attached to a length of suture and a band having at least two prongs extending from a proximal edge of the band. The prongs are configured to engage with the needle to allow the needle to extract the leader from the cavity and deliver it to the needle exit port.
