Filamentous tissue implant

摘要

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.
