Repositionable surgical anchors
Embodiments related to surgical anchors are described. In some embodiments, a surgical anchor may include a selectively removable blocker which may prevent one or more barbs of the surgical anchor from engaging with adjacent tissue until the selectively removable blocker is removed.
1. A method of implanting an implantable prosthesis for repairing a defect in a tissue, the method comprising:
inserting a surgical anchor into the tissue;
removing a blocker disposed in a slot formed in the surgical anchor to expose one or more barbs of the surgical anchor, wherein the slot extends through a proximal surface of the surgical anchor; and
engaging the one or more barbs with adjacent tissue.
2. The method of claim 1 , further comprising positioning the implantable prosthesis adjacent to the tissue and affixing the implantable prosthesis to the tissue with the surgical anchor.
3. The method of claim 1 , further comprising removing the surgical anchor from the tissue prior to removing the blocker and repositioning the surgical anchor and/or the implantable prosthesis relative to the tissue.
4. The method of claim 3 , further comprising reinserting the surgical anchor into the tissue.
5. The method of claim 1 , wherein removing the blocker from the surgical anchor includes pulling a tab of the blocker.
6. The method of claim 1 , further comprising positioning the blocker against a proximal portion of the one or more barbs to block the one or more barbs from engaging with adjacent tissue.
7. The method of claim 1 , further comprising the surgical anchor exhibiting a pullout force of at least 0.16 lbf.
8. The method of claim 1 , further comprising inserting at least a second surgical anchor into the tissue, the surgical anchor and the second surgical anchor connected by a rigid backing.
9. The method of claim 1 , further comprising inserting the blocker through an opening of the slot located on the proximal surface of the surgical anchor.
10. The method of claim 1 , wherein at least one of the surgical anchor and the implantable prosthesis are bioresorbable.
11. The method of claim 1 , wherein the surgical anchor is one of a plurality of surgical anchors.
12. A method of implanting an implantable prosthesis for repairing a defect in a tissue, the method comprising:
inserting one or more surgical anchors into the tissue, wherein the one or more surgical anchors are attached to the implantable prosthesis;
removing a blocker from a slot of each surgical anchor of the one or more surgical anchors to expose one or more barbs of the one or more surgical anchors, wherein the slot of each surgical anchor extends through a proximal surface of the surgical anchor; and
engaging the one or more barbs with adjacent tissue.
13. The method of claim 12 , wherein the implantable prosthesis includes a patch body.
14. The method of claim 12 , further comprising positioning the implantable prosthesis adjacent to the tissue and affixing the implantable prosthesis to the tissue with the one or more surgical anchors.
15. The method of claim 13 , further comprising removing the one or more surgical anchors from the tissue prior to removing the blocker and repositioning the one or more surgical anchors and/or the implantable prosthesis relative to the tissue.
16. The method of claim 15 , further comprising reinserting the one or more surgical anchors into the tissue.
17. The method of claim 12 , wherein removing the blocker from the one or more surgical anchors includes pulling a tab of the blocker.
18. The method of claim 12 , further comprising positioning the blocker against a proximal portion of the one or more barbs to block the one or more barbs from engaging with adjacent tissue.
19. The method of claim 12 , wherein the one or more surgical anchors exhibit a pullout force of at least 0.16 lbf.
20. The method of claim 12 , wherein the one or more surgical anchors include a first surgical anchor and a second surgical anchor connected by a rigid backing.
21. The method of claim 12 , further comprising inserting the blocker through an opening of the slot located on the proximal surface of each surgical anchor of the one or more surgical anchors.
22. The method of claim 12 , wherein at least one of the one or more surgical anchors and the implantable prosthesis are bioresorbable.
23. The method of claim 12 , wherein the one or more surgical anchors is a plurality of surgical anchors.
