FILAMENTOUS TISSUE IMPLANT
A tissue fixation system including a delivery tube and an elongated fastener with a loop at a proximal end and a distal end, A proximal end of an elongated curved needle is attached to the delivery tube. A distal end of the needle is configured to penetrate tissue. The needle includes an open channel sized to receive the elongated fastener with the loop located near the proximal end of the elongated curved needle and the distal end of the elongated fastener located near the distal end of the elongated curved needle. A capture needle is slidably positioned in the delivery tube to slide through the loop in the proximal end of the elongated fastener. The capture needle is configured to grasp the distal end of the elongated fastener and pull the distal end of the elongated fastener through the loop to cinch the elongated fastener.
1 . A method of engaging a tissue fixation system to two or more layers of material, the method comprising the steps of:
coupling an elongated fastener to an elongated curved needle, the elongated curved needle comprising a proximal end attached to a delivery tube and a distal end configured to penetrate the two or more layers of material;
inserting the distal end of the elongated curved needled and a portion of the elongated fastener though the two or more layers of material;
advancing a capture needle through the delivery tube and through at least one loop in the elongated fastener; mechanically capturing the elongated fastener with the capture needle;
retracting the capture needle through the deliver tube;
pulling the elongated fastener through the loop to cinch the elongated fastener to the two or more layers of material; and detaching the delivery tube and the elongated curved needle from the elongated fastener.
