Implantable tendon protection systems and related kits and methods
An implantable tendon protection system includes a body adapted to be implanted within a bursa overlying a tendon of a patient to protect the tendon. The body may be fixed to the tendon with adhesive, sutures, staples, and/or anchors. A surgical kit is provided with such a tendon protection system and an insertion cannula. Methods of protecting a tendon of a patient are also disclosed.
1. An implant delivery system for delivering an implantable device, the implant delivery system comprising:
a barrel having a proximal end and a distal end configured to be laterally inserted into a bursa in a shoulder of a patient;
a sheath with an interior space disposed within the barrel and slidable relative to the barrel; and
an implantable device, wherein the implantable device is adapted to be collapsed and held within the interior space of the sheath, the implantable device configured to expand to an expanded configuration when the sheath slides towards the proximal end of the barrel and the implantable device is not held within the interior space of the sheath, wherein the system is configured to deliver the implantable device to an area adjacent and substantially parallel to a supraspinatus tendon in the shoulder of the patient,
wherein the implantable device comprises:
a first bioabsorbable layer;
a second layer;
an intermediate layer disposed between the first layer and the second layer, the intermediate layer including a plurality of channels; and
an inlet for injecting fluid into one or more of the plurality of channels.
2. The implant delivery system of claim 1 , wherein the expanded configuration of the implantable device is substantially parallel to a plane of the barrel.
3. The implant delivery system of claim 1 , further comprising a pharmacological agent in fluid communication with the implant delivery system.
4. The implant delivery system of claim 1 , further comprising an adhesive in fluid communication with the implant delivery system.
5. The implant delivery system of claim 1 , wherein the implantable device is configured to be overlaid on the supraspinatus tendon.
6. The implant delivery system of claim 5 , wherein the supraspinatus tendon is partially torn.
7. The implant delivery system of claim 1 , wherein the barrel is configured to be inserted into the bursa in the shoulder of the patient from the front or back of the patient's shoulder.
8. The implant delivery system of claim 1 , wherein the delivery system is configured to urge the implantable device into the expanded configuration.
9. The implant delivery system of claim 1 , wherein the implantable device is self-deploying.
10. The implant delivery system of claim 1 , wherein the implantable device has a folded or pleated configuration in a collapsed position.
11. The implant delivery system of claim 1 , wherein the implantable device has a rolled configuration in a collapsed position.
12. The implant delivery system of claim 1 , wherein the implantable device has an umbrella type shape in a collapsed position.
13. The implant delivery system of claim 12 , wherein the implantable device includes arms that expand the implant to the expanded configuration.
14. A method of treating a rotator cuff of a shoulder of a patient, comprising:
providing an implant delivery device comprising a barrel with a distal end, a sheath comprising a lumen, and an implant, wherein the implant is constrained within the lumen of the sheath, the implant comprising:
a first bioabsorbable layer;
a second layer;
an intermediate layer disposed between the first layer and the second layer, the intermediate layer including a plurality of channels; and
an inlet for injecting fluid into one or more of the plurality of channels;
laterally inserting the distal end of the barrel into a target site in the shoulder of the patient;
pulling back on a distal end of the sheath such that the implant is released from the constrained position;
expanding the implant to a deployed configuration, wherein the implant in the deployed configuration is substantially parallel to a supraspinatus tendon in the shoulder of the patient; and
attaching the implant to the supraspinatus tendon.
15. The method of claim 14 , wherein inserting the barrel into the target site includes inserting into the bursa.
16. The method of claim 15 , wherein inserting the barrel into the target site includes inserting into the bursa from the front or back of the patient's shoulder.
17. The method of claim 14 , wherein the implant is self-deploying.
18. The method of claim 14 , wherein expanding the implant to a deployed configuration includes urging the implant to assume the deployed configuration.
19. The method of claim 14 , wherein the implant has a folded or pleated configuration in the constrained position.
20. The method of claim 14 , wherein the implant has a rolled configuration in the constrained position.
21. The method of claim 14 , wherein the implant has an umbrella type shape in the constrained position.
22. The method of claim 14 , wherein the implant is deployed in the bursa over the supraspinatus tendon.
23. The method of claim 14 , further comprising inflating the shoulder at the target site prior to expanding the implant.
24. The method of claim 23 , wherein inflating the shoulder is done using saline.
25. The method of claim 14 , further comprising removing the device from the shoulder.
26. The method of claim 25 , further comprising closing the bursa after removing the device from the shoulder.
27. The method of claim 14 , wherein attaching the implant to the supraspinatus tendon is done using adhesive.
28. The method of claim 14 , wherein attaching the implant to the supraspinatus tendon is done using staples or sutures.
29. The method of claim 14 , further comprising delivering a therapeutic or diagnostic agent to tissue adjacent to the target site.
