A laparascopic incision closure device comprised of an ejector housing having a handpiece trigger that is activated by compression and is biased to return to an initial position. The handpiece is so carried by the ejector housing that compression and retraction of the handpiece sequentially advances a flexible wire push-rod to eject a T-bar suture and retracts the flexible wire push-rod to index a ratchet which feeds the T-bar portion of a T-bar suture into the longitudinal bore of a needle carried by the ejector housing. The strand portion of the T-bar suture trails the T-bar portion through the longitudinal bore. Multiple T-bar sutures are axially spaced and detachably carried on a suture spline by spline mount tabs connected to the T-bar portion of the T-bar sutures and are stored in the interior of the ejector housing for quick and easy placement through fascia on opposite sides of a wound. In the preferred embodiment the device is constructed of a disposable plastic material with sutures being formed of an absorbable material.

1. A laparascopic incision closure device comprising:a housing; a needle having a longitudinal axis, a proximal and distal end, and an axially extending longitudinal bore therethrough where said needle has a radial distal opening in said distal end and a radial proximal opening in said proximal end

1. A laparascopic incision closure device comprising:a housing; a needle having a longitudinal axis, a proximal and distal end, and an axially extending longitudinal bore therethrough where said needle has a radial distal opening in said distal end and a radial proximal opening in said proximal end and where said longitudinal bore communicates only with said radial distal opening and said radial proximal opening forming a continuously bounded passageway, and where said needle is attached to said housing at said proximal end; a plurality of T-bar sutures where each said T-bar suture comprises a T-bar portion and a suture portion integrally connected, and where said suture portion is so adapted and disposed in said housing and said longitudinal bore so as to permit axial passage of said T-bar portion and said suture portion through said longitudinal bore, and where said plurality of T-bar sutures are stored in said housing and said longitudinal bore; ejection means for sequentially ejecting said T-bar portion and said suture portion through said radial distal opening and through tissue adjacent to an incision; whereby a Laparascopic incision can be quickly and efficiently closed by sequential placement of a T-bar suture on opposite sides of said incision and then tying said respective suture portions to close the wound.
