A method for securing an implant to tissue of a patient using a fixation apparatus and a delivery apparatus releasably carrying the fixation apparatus. The fixation apparatus includes first and second anchors and an adjustable band connecting the anchors. The band includes a cinch line and a tether
A method for securing an implant to tissue of a patient using a fixation apparatus and a delivery apparatus releasably carrying the fixation apparatus. The fixation apparatus includes first and second anchors and an adjustable band connecting the anchors. The band includes a cinch line and a tether connected to one of the anchors. The delivery apparatus includes a body, a tubular shaft, a displacement rod within the tubular shaft, and an actuator. The method comprises positioning the implant in proximity to the tissue, deploying the anchors into or through the tissue, and applying tension to the cinch line to foreshorten the adjustable band and secure the implant to the tissue with at least a portion of the implant positioned between the band and the tissue.
1. A method of anchoring an implant to tissue of a patient, the method comprising: providing a delivery apparatus releasably carrying a fixation apparatus, the delivery apparatus including a body, a tubular shaft extending from the body and having a distal end, a displacement rod longitudinally disp
1. A method of anchoring an implant to tissue of a patient, the method comprising: providing a delivery apparatus releasably carrying a fixation apparatus, the delivery apparatus including a body, a tubular shaft extending from the body and having a distal end, a displacement rod longitudinally displaceable within the body and the tubular shaft and including a proximal end and a distal end, a tether severing element in the body including a cutting edge, and an actuator coupled to the body and attached to the proximal end of the displacement rod, the fixation apparatus including first and second anchors, a flexible band connecting the first and second anchors and including a cinch line releasably coupled to the delivery apparatus, and a tether extending through the tubular shaft, the tether having a proximal end and a distal end, the proximal end of the tether attached to the delivery apparatus within the body of the delivery apparatus, and the distal end of the tether attached to the second anchor;positioning the implant in proximity to the tissue;inserting the distal end of the tubular shaft into or through the tissue at a first location;operating the actuator to deploy the first anchor into or through the tissue;relocating the delivery apparatus to a second location different than the first location, the second location selected such that at least a portion of the implant is located between the band and the tissue;inserting the distal end of the tubular shaft into or through the tissue at the second location;operating the actuator to deploy the second anchor into or through the tissue, wherein operating the actuator to deploy the second anchor includes severing the tether by the cutting edge;applying tension to the cinch line to foreshorten the band between the first and second anchors, thereby securing the implant to the tissue with the at least a portion of the implant positioned between the band and the tissue. 2. The method of claim 1 wherein the fixation apparatus includes a first suture connected to the first anchor, a separate, second suture connected to the second anchor, and wherein the band includes a separate, third suture coupled to the first and second sutures, the third suture forming a suture loop having an adjustable length, and wherein applying tension to the cinch line foreshortens the adjustable length of the suture loop. 3. The method of claim 2 wherein the first and second sutures are each in the form of a suture loop, and wherein the third suture extends through the loops formed by the first and second sutures such that the first and second anchors are slidably coupled to the third suture. 4. The method of claim 1 wherein the delivery apparatus further includes a system for regulating movement of the actuator and the displacement rod. 5. The method of claim 4 wherein operating the actuator to deploy the first anchor includes advancing the actuator and the displacement rod a first distance so as to eject the first anchor from the distal end of the tubular shaft, and wherein the tether is operable to resist expulsion of the second anchor from the tubular shaft during deployment of the first anchor. 6. The method of claim 5 wherein operating the actuator to deploy the second anchor includes advancing the actuator and the displacement rod a second distance so as to eject the second anchor from the distal end of the tubular shaft. 7. The method of claim 6 wherein operating the actuator to deploy the second anchor includes severing the tether so that the tether does not resist ejection of the second anchor from the distal end of the tubular shaft. 8. The method of claim 1 wherein the delivery apparatus includes a guide extending into the body, a guide spring biasing the guide toward the actuator, and a displacement spring in the body biasing the displacement rod in a proximal direction and away from the distal end of the tubular shaft, and wherein the actuator includes a groove, and wherein the guide extends into and is slidably received by the groove so as to regulate movement of the actuator and the displacement rod. 9. The method of claim 8 wherein the groove includes a first longitudinally extending portion having a first length, and a second longitudinally extending portion having a second length, and wherein operating the actuator to deploy the first anchor includes advancing the actuator a first distance corresponding to the first length, and wherein operating the actuator to deploy the second anchor includes advancing the actuator a second distance corresponding to the second length. 10. The method of claim 9 wherein the groove further includes a radially extending portion between the first and second longitudinally extending portions, and wherein the method further comprises rotating the actuator relative to the body after advancing the actuator the first distance. 11. The method of claim 10 wherein advancing the actuator the second distance is performed after rotating the actuator relative to the body. 12. The method of claim 11 wherein advancing the actuator the second distance causes the tether line to be severed within the body. 13. The method of claim 12 further comprising removing excess lengths of the tether and the cinch line. 14. The method of claim 1 wherein the implant is a therapeutic device. 15. The method of claim 14 wherein the implant is an orthopedic device. 16. The method of claim 15 wherein the orthopedic device is a mesh configured to repair a defect in an annulus of an intervertebral disc.
