1. A fastener system comprising:
- a flexible hollow fastener comprised of fibers of a biocompatible polymeric material;
a flexible elongated fastening member extending through the flexible hollow fastener such that two legs of the flexible elongated fastening member extend from the flexible hollow fastener to enable a user to tension the flexible elongated fastening member, wherein at least a portion of the flexible elongated fastening member is fabricated in part with polyethylene; and
an introducer comprised of a pushrod, the pushrod having a distal portion configured to engage the flexible hollow fastener and position the flexible hollow fastener relative to a body tissue, wherein the flexible hollow fastener and flexible elongated fastening member are positioned on the distal end of the pushrod,wherein the flexible hollow fastener is configured to deform from a first configuration to a second configuration to secure the flexible hollow fastener and the flexible elongated fastening member when at least one of the two legs of the flexible elongated fastening member are tensioned relative to the body tissue, andwherein the flexible elongated fastening member is configured to slide through the flexible hollow fastener under tension when the flexible hollow fastener is in the first configuration and the second configuration.

Abstract
The guidance and positioning device may be a system for creating a passage in tissue, positioning fasteners or other implants, and tensioning an elongated fastening member, like a suture, thread, wire, or pin. In some embodiments, the device may allow for the implantation of multiple sutures and fasteners in tissue. A fastener may be positioned at the distal end of a flexible pushrod. The fastener may be connected with the pushrod or may be loosely fitted with the distal end of the pushrod. A suture may be looped through or connected with the fastener such that one, two, or more sections, legs, strands, or portions of the suture extend from the fastener.
