An instrument, a closure, and method of use for sealing an opening, e.g., a percutaneous incision or puncture, in a living being. The instrument includes a tubular carrier storing the closure. The carrier has a distally located free end to be extended through the opening. The closure comprises an anchoring portion, a sealing portion and a thin filament connected therebetween. The instrument is operated to eject the anchoring portion of the closure through the incision or puncture and to then draw that portion against the free end of the carrier. The instrument is then withdrawn to pull the anchoring portion of the closure against the tissue contiguous with the incision or puncture. Further withdrawing of the instrument draws the sealing portion of the closure out of the carrier, whereupon it moves with respect to the anchoring portion and into engagement with the tissue contiguous with the opening on the opposite side of the anchoring portion to seal it. Signals are produced to indicate proper operation.
An instrument for sealing an opening in tissue separating one portion of the body of a living being from another portion thereof, said instrument comprising carrier means for receipt of closure means, said closure means being arranged to be expelled from said carrier means, said carrier means compri
An instrument for sealing an opening in tissue separating one portion of the body of a living being from another portion thereof, said instrument comprising carrier means for receipt of closure means, said closure means being arranged to be expelled from said carrier means, said carrier means comprising tubular means having a proximally located portion and a distally located portion, said distally located portion having a free end arranged to be introduced through said opening, said closure means comprising anchoring means, sealing means, and filament means, said anchoring means including a tissue engaging portion configured to pass through said opening in one direction but resistant to passage therethrough in the opposite direction, said sealing means including a tissue engaging portion, said filament means being connected between said anchoring means and said sealing means and comprising a first portion and a second portion, said instrument being arranged to expel said anchoring means through said opening and to draw said tissue engaging portion of said anchoring means into engagement with the tissue contiguous with said opening, said first portion of said filament means being arranged to be drawn in the proximal direction by a force applied thereto, whereupon said second portion of said filament means causes said tissue engaging portion of said sealing means to move with respect to said anchoring means and into engagement with the tissue contiguous with said opening on the opposite side thereof from said anchoring means, whereupon said tissue engaging portion of said sealing means seals said opening from the flow of fluid therethrough.
