ABSTRACT:
An instrument for delivering a pre-tied suture assembly, having a needle carrying a thread with a noose thereon, into a body cavity. The needle has a pointed free end to puncture a tissue and guide movement of the needle and thread therethrough. The instrument has an elongate body with proximal and distal ends. Structure is provided on the body for holding the needle in a transfer position with the pointed free end of the needle shielded to prevent inadvertent puncture of a tissue as the suture assembly is introduced into a body cavity through the instrument. The body has a noose receiving portion to be surrounded by the noose with the needle in its transfer position to prevent the noose from closing upon itself. There is first structure on the elongate body for a) preventing a noose on the noose receiving portion from sliding from the noose receiving portion off of the distal free end of the body with the first structure in a first position and b) allowing a noose to slide from the noose receiving portion off of the distal free end of the body with the first structure in a second position.
