Medical device delivery system and method

1. A method for positioning a tendon repair implant, the method comprising the steps of:

temporarily affixing a distal tip of a guide to tissue at a target site of a shoulder;

positioning a tendon repair implant against a tendon of the shoulder with the guide extending through the tendon repair implant;

fixing the tendon repair implant to the tendon; and

removing the guide from the target site after fixing the tendon repair implant to the tendon.

2. The method of claim 1 , further comprising expanding the tendon repair implant to assume an expanded shape prior to positioning the tendon repair implant against the tendon.

3. The method of claim 2 , wherein the tendon repair implant is advanced to the target site in a collapsed shape within a sheath of a tendon repair implant delivery system.

4. The method of claim 3 , wherein the tendon repair implant delivery system includes a support extendable from a distal opening of the sheath.

5. The method of claim 4 , further comprising urging the tendon repair implant to assume the expanded shape by extending the support from the distal opening of the sheath.

6. The method of claim 5 , further comprising holding the tendon repair implant against the tendon with the support while fixing the tendon repair implant to the tendon.

7. The method of claim 6 , wherein fixing the tendon repair implant to the tendon comprises advancing an anchor into the tendon.

8. The method of claim 1 , wherein fixing the tendon repair implant to the tendon comprises fixing the tendon repair implant to the tendon while the tendon repair implant is held in contact with the tendon.

9. The method of claim 8 , wherein fixing the tendon repair implant to the tendon comprises advancing an anchor into the tendon.

10. A method for positioning a tendon repair implant to overlay at least a portion of a supraspinatus tendon of a shoulder, the method comprising the steps of:

temporarily affixing a temporary fixation member to tissue at a tendon repair site on a bursal side of the supraspinatus tendon;

positioning a tendon repair implant against the bursal side of the supraspinatus tendon with the temporary fixation member extending through the tendon repair implant;

fixing the tendon repair implant to the bursal side of the supraspinatus tendon while the temporary fixation member is extending through the tendon repair implant; and

removing the temporary fixation member from the tissue at the tendon repair site after fixing the tendon repair implant to the bursal side of the supraspinatus tendon.

11. The method of claim 10 , further comprising expanding the tendon repair implant to overlie a portion of the supraspinatus tendon in an expanded configuration.

12. The method of claim 11 , wherein the tendon repair implant is configured and adapted to assume a compact configuration prior to expanding the tendon repair implant.

13. The method of claim 12 , further comprising holding the tendon repair implant against the supraspinatus tendon with a support while fixing the tendon repair implant to the supraspinatus tendon.

14. The method of claim 13 , wherein fixing the tendon repair implant to the supraspinatus tendon comprises advancing an anchor into the supraspinatus tendon.

15. A method of positioning a tendon repair implant at a treatment site comprising:

positioning an implant delivery device at a target treatment site within a shoulder of a patient;

deploying a tendon repair implant from the implant delivery device at the target treatment site;

causing the tendon repair implant to transition from a compact configuration to an expanded configuration at the target treatment site;

pressing the tendon repair implant against the target treatment site in the expanded configuration; and

attaching the tendon repair implant to the target treatment site while a temporary fixation member of the implant delivery device is extended through the tissue tendon repair implant and fixed to tissue underlying the tendon repair implant at the target treatment site.

16. The method of claim 15 , wherein the target treatment site includes a supraspinatus tendon.

17. The method of claim 15 , further comprising detaching the temporary fixation member from the tissue underlying the tendon repair implant after attaching the tendon repair implant to the target treatment site.
