Description

CROSS-SECTION TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 17/877,930, filed on Jul. 30, 2022, which is a divisional of Running et al., U.S. Patent Application Publ. No. 2021/0275161, published Sep. 9, 2021, now issued as U.S. Pat. No. 11,413,032 and entitled “Surgical Anchoring Device, Deployment Device, and Method of Use,” which claims the benefit of U.S. Provisional Patent Application No. 62/972,718, filed on Feb. 11, 2020, and titled “Anchoring Device for Tissue and Method of Insertion,” and U.S. Provisional Patent Application No. 62/972,722, filed on Feb. 11, 2020, and titled “Deployment Device for Inserting Anchors into Tissue.” The entire disclosure of each application listed above is incorporated herein by reference. BACKGROUND The present embodiments relate generally to medical devices, and in particular to medical devices used to repair tissue. Rotator cuff repair is a surgical procedure performed to repair torn (or partially torn) tendons in the shoulder. This procedure can be done with large incisions or with arthroscopic techniques. To repair a torn tendon (such as the supraspinatus tendon), a surgeon may use anchors and sutures to reattach the tendon to the humerus bone. The repaired area may then be covered with a graft to facilitate healing. Currently, grafts may be applied using anchors to fix the graft to the underlying tendon and/or bone. The anchors may cause inflammation. Additionally, the anchors are implanted by inserting a device through one or more openings at the top of the shoulder, which can make it difficult to access all of the desired joint spaces. There is a need in the art for a system and method that addresses the shortcomings discussed above. SUMMARY In one aspect, the present disclosure is directed to a surgical anchoring device. The anchoring device may include a first beam and a second beam each extending along a longitudinal direction and a connecting member bridging a first proximal portion of the first beam to a second proximal portion of the second beam such that the first beam is substantially aligned with the second beam. In addition, the anchoring device may include a first barb protruding from a medial side of the first beam, wherein the first barb extends diagonally in a generally proximal direction. The first barb may include a proximal facing surface that is separated from the first beam by a recess. In another aspect, the present disclosure is directed to a surgical anchoring device. The anchoring device may include a first beam and a second beam bridged by a connecting member. The anchoring device may further include a first set of barbs protruding from the first beam, the first set of barbs including a first barb and a second barb; and a second set of barbs protruding from the second beam, the second set of barbs including a third barb and a fourth barb. At least one of the barbs may include a tip portion corresponding to an intersection of a proximal surface, a first side surface, a second side surface, and a distal ridge surface. In another aspect, the present disclosure is directed to method of implanting a surgical anchoring device. The method may include providing a deployment device loaded with a first anchoring device comprising a frame structure including a first beam and a second beam bridged together by a connecting member and having a retention portion proximate a distal end of the first anchoring device configured to resist withdrawal of the anchoring device from tissue. The deployment device may further include at least one pair of needle members, including a first needle member and a second needle member configured to receive the first beam and the second beam of the first anchoring device, at least one anchor engaging rod configured to engage with the first anchoring device when disposed within the needle members; and at least one pushing member configured engage the pair of needle members and the anchor engaging rod. The method may include actuating the at least one pushing member, thereby translating the pair of needles and the first anchoring device from a first position within the deployment device to a second position extending from the distal end of the deployment device. The method may also include retracting the needle members independent of the anchor engaging rod such that the anchor engaging rod maintains the anchoring device in the second position, thereby releasing the anchoring device from the needle members. Other systems, methods, features, and advantages of the embodiments will be, or will become, apparent to one of ordinary skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description and this summary, be within the scope of the embodiments, and be protected by the following claims.
