shaped and the proximal end 23 a includes tabs 25 and a recessed portion 26 located between the tabs 25 and the distal end 23 b . the recessed portion 26 allows the tabs 25 to expand , as will be further described below . although fig2 a and 2b show two tabs 25 , a higher or lesser number of tabs 25 may be present . the first and second surfaces 22 , 23 are configured to allow the surfaces 22 , 23 to conform to the surfaces 17 , 18 of the plug distal portion 15 , thereby allowing for easier receipt of the plug 20 into the internal bore 12 of the anchor 10 , as will be further described below . the plug 20 also includes an internal cavity 27 having surface features 28 , such as threads , and a transverse through hole 29 . the cavity 27 extends into the through hole 29 . the locking member 30 includes a head 31 and a shaft 32 coupled to the head 31 . the shaft 32 includes surface features 33 , such as threads , configured for engagement with the threads 28 of the plug 20 when the locking member 30 is disposed within the plug 20 , as shown in fig2 b . the anchor 10 of the present disclosure may be used in conjunction with another anchor to repair soft tissue . fig3 a and 3b show the anchor 10 located on the shaft 41 of a delivery device 40 in preparation for insertion of the anchor 10 into bone , as will be more fully described below . the delivery device 40 includes the shaft 41 having a distal portion 41 a , configured for engagement with the internal bore 12 of the anchor 10 , and a proximal portion 41 b coupled to a handle 42 . as shown in fig3 b , the distal portion 41 a includes a pointed end 41 a 1 , a first surface 41 a 2 , and a second surface 41 a 3 . the first and second surfaces 41 a 2 , 41 a 3 are configured to allow the surfaces 41 a 2 , 41 a 3 to conform to the surfaces 17 , 18 of the internal bore 12 , thereby allowing for easier receipt of the internal bore 12 onto the distal portion 41 a . fig4 a - 4e show the anchoring system 50 in use during arthroscopic repair of the rotator cuff . however , the anchoring system 50 may be used in the repair of soft tissue in other parts of the body . fig4 a shows a first anchor 60 that has been inserted into the lateral aspect of a bone 70 , such as a humeral bone . the anchor 60 , which has a flexible member 80 , such as a suture , coupled thereto , is inserted into the bone 70 , a soft tissue 90 , such as a rotator cuff tendon , is placed on the bone 70 to be located adjacent to the anchor 60 , and the ends 81 of the flexible member 80 are placed through the soft tissue 90 . next , the delivery device 40 is used to place a second anchor , such as the anchor 10 of the present disclosure , into the medial aspect of the bone 70 . the pointed end of 41 a 1 of the shaft 41 is used as an awl to start the hole 71 , by tapping the handle 42 with a surgical mallet , or other axially oriented , advancement force . the delivery device 40 is axially advanced into the hole 71 until the distal portion 11 b of the anchor 10 is no longer exposed , as shown in fig4 a . the delivery device 40 is then rotated until the proximal portion 11 a of the anchor 10 is no longer exposed , as shown in fig4 b . the delivery device 40 allows for the creation of the hole 71 and insertion of the anchor 10 in one step , rather than multiple steps . the delivery device 40 and anchor 10 are shown in an enlarged view compared to fig4 c - 4e where the anchor 10 is much smaller in size . the anchor 10 and delivery device 40 are shown in an enlarged view merely for the purposes of an increased level of detail and for further understanding of the repair process . subsequent to the anchor 10 being placed in the bone 70 , the delivery device 40 is removed , and at least one end 81 of the flexible member 80 is passed through the transverse through hole 29 of the plug 20 . the plug 20 is then placed into the internal bore 12 of the anchor 10 , as shown in fig4 c , such that the ends 81 extend out of the hole 71 . after placement of the plug 20 into the anchor 10 , the ends 81 of the flexible member 80 may be pulled to provide a preferred amount of tension on the flexible member 80 and the soft tissue 90 . this tension on the flexible member 60 can be seen in fig4 d , especially when comparing these figures to fig4 c . as shown in fig4 d and 4e , after insertion of the plug 20 into the inner bore 12 of the anchor 10 , the locking member 30 is advanced into the internal cavity 27 of the plug 20 , such that , as will be further described below , the plug 20 expands to lock the plug 20 within the inner bore 12 of the anchor 10 . in addition , advancement of the locking member 30 secures the flexible member 80 within the through hole 29 and the internal bore 12 and secures the tissue 90 to the bone 70 . as shown in fig5 , advancement of the locking member 30 into the inner bore 12 causes the tabs 25 to expand outward 25 a and into the groove 16 of the bore 12 , thereby locking the plug 20 within the bore 12 . also shown is the impingement of the locking member 30 on the flexible member 80 , which secures the flexible member 80 within the through hole 29 . both the plug 20 and the locking member 30 are advanced via delivery tools that provide for axial and rotary advancement . the suture 80 may need to be retensioned subsequent to placing the locking member 30 into the plug 20 . if re - tensioning is necessary , the delivery tools may be used to remove the locking member 30 , so that tension mat be applied to the suture 80 . the locking member 30 would then be re - inserted into the plug 20 . the anchor 10 and plug 20 of the present disclosure and the first anchor 60 are made from a bioabsorbable polymer material via an injection molding process . however , other materials and processes may be used . in addition , the suture material is made from a bioabsorbable polymer material , but other material may be used . also , the initial anchor , such as the first anchor 40 shown above , may include more than one suture and the sutures may be secured together at one attachment point , such as within the second anchor 10 shown above , or independently at more than one attachment point . for the purposes of this disclosure , the locking member 30 is made from a biocompatible material , such as titanium , stainless steel , or polyetheretherketone ( peek ). however , the locking member 30 may be made from other absorbable or non - absorbable material . furthermore , the proximal portion 11 a of the anchor 10 may include features other than threads to reduce the possibility of removal of the anchor 10 and the threads may extend the entire length of the anchor 10 . similarly , the outer wall 21 of the plug 20 and the internal bore 12 of the anchor 10 may include surface features other than those shown and described to facilitate insertion and removal of the anchor 10 onto the shaft 41 and the plug 20 within the internal bore 12 of the anchor 10 . in addition , the inner cavity 27 of the plug 20 and the shaft 31 of the locking member 30 may include surface features other than threads 28 , 33 for engagement of the locking member 30 with the plug 20 . also , for the purposes of this disclosure , the location of the through hole 29 may be anywhere along the length of the plug 20 . the shaft 41 of the delivery device 40 is made from a biocompatible material , such as stainless steel , and is coupled to the handle 42 by having the proximal portion 41 b press - fit into a through hole 43 of the handle 42 . however , other materials and methods of coupling may be used . the anchoring system 50 of the present disclosure allows a surgeon to load a suture from a previously placed anchor and secure the suture in the system 50 at a preferred tension . furthermore , the system 50 allows for one or more sutures to be secured together at one attachment point , such as described above with the second anchor 10 , or independently at several attachment points . this allows for a large area of contact between the tissue and the bone and results in a better repair . as various modifications could be made to the exemplary embodiments , as described above with reference to the corresponding illustrations , without departing from the scope of the disclosure , it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative rather than limiting . thus , the breadth and scope of the present disclosure should not be limited by any of the above - described exemplary embodiments , but should be defined only in accordance with the following claims appended hereto and their equivalents .
the present disclosure relates to an anchor assembly . the anchor assembly includes an anchor defining a cavity and an opening to the cavity and an insertion member including a body having a proximal end portion and a flat distal end portion , and a head coupled to the proximal end portion of the body . the insertion member is configured for arrangement within the anchor cavity . a method of tissue repair and other anchor assemblies are also disclosed .
