         [0080]    The insertion member  300  includes a body  310  having threads  310   a , a distal portion  310   b , and a proximal portion  310   c . As shown in  FIGS. 8, 11, and 12 , the member  300  includes a triangular-shaped cannulation  310   d  that extends a partial length of the member  300 . The threads  310   a  are configured for engagement with the threads  230   c  of the cavity  230  when the insertion member  300  is arranged within the cavity  230 , as will be further explained below. 
         [0081]      FIGS. 13-14, 14A-14B, 15, and 15A-15B  show the delivery device  400  of the present disclosure for use with the anchor assembly  100  of  FIG. 8 . The device  400  includes a shaft  410 , a handle  420  coupled to the shaft  410 , and a knob  430  coupled to the handle  420 . The shaft  410  includes an outer member  410   a  and an inner member  410   b  slidably disposed within and coupled to the outer member  410   a . The inner member  410   b  includes a distal end  410   b ′ configured for disposal within the cannulation  310   d  of the insertion member  300  and a proximal end  410   b ″ coupled to the knob  430 . The end  410   b ′ is of a diameter such that it engages the wall  310   d ′ of the cannulation  310   d , thereby allowing movement of the member  30  when the knob  430  is rotated, as will be further described below. The outer member  410   a  includes prongs  410   c  located at a distal end  410   a ′ of the outer member  410   a  and a proximal end  410   a ″ coupled to the handle  420 . 
         [0082]    Prior to use, suture  440  is disposed within the through hole  250  and ends  440   a ,  440   b  of the suture  440  are fixed to suture holders  450  located on handle  420 . The suture  440  helps to keep anchor  200  coupled to the shaft  410 . The delivery device  400  and its components, especially the knob  430 , is similar to the delivery device shown and described in the &#39;869 publication. The ends  440   a ,  440   b  of the suture  440  are also housed within channels  460  that extend along the shaft  410 . A suture threader  12000  is also releasably coupled to the shaft  410 . Threader  12000  includes a clip  12000   a  and a loop of suture  12000   b  coupled to the clip  12000   a . Suture loop  12000   b  is disposed within the through hole  250  and placed around the clip  12000   a.    
         [0083]    As shown in  FIGS. 14A and 15A , the prongs  410   c  are disposed within the depressions  260 . Once the anchor assembly  100  is disposed within bone, the prongs  410   c  help to hold the anchor  200  stationary while the insertion member  300  is moved relative to the anchor  200  via rotation of the knob  430 . As will be further described below,  FIG. 14A  shows the location of the insertion member  300  prior to fixation of suture within the through hole  250 , while  FIG. 15A  shows the location of the insertion member  300  after fixation of suture within the through hole  250 . 
         [0084]    Additionally, as shown in  FIGS. 14B and 15B , the proximal end  410   b ″ of the inner member  410   b  includes threads  410   d  on an outer surface  410   e  of the inner member  410   b  and the proximal end  410   a ″ of the outer member  410   a  includes threads  410   f  on an inner surface  410   g  of the outer member  410   a . Threads  410   f  engage threads  410   d  to allow for coupling of the outer and inner members  410   a ,  410   b  and axial movement of the inner member  410   b  relative to the outer member  410   a . Axial movement of the inner member  410   b  relative to the outer member  410   a  allows for axial movement of the insertion member  300  to the two locations shown in  FIGS. 14A and 15A . Member  410   b  also includes a depth stop  410   b ′″ that engages an end  410   a ′″ of member  410   a , as shown in  FIG. 15B , once member  300  is located as shown in  FIG. 15A . Interaction of the depth stop  410   b ′″ with the end  410   a ′″ ceases axial movement of the member  300  toward the through hole  250  and prevents the member  300  from being overly inserted into the cavity  230 . The insertion member  300  is moved axially towards the through hole  250  to engage the flexible member and secure the flexible member within the cavity  230 , which will be further described below. 
         [0085]      FIGS. 16-27  show the anchor assembly  10 ,  100  of the present disclosure in use during soft tissue repair, specifically to repair labrum tears in the shoulder. As shown in  FIG. 16 , the labrum  2000  has been torn away from the glenoid cavity  3000  and is in need of being re-attached.  FIG. 16  shows a monofilament suture loop  4001  from a suture passer  4000  being inserted through the labrum  2000  via use of a first cannula  5000 . A grasper  6000  from a second cannula  7000  grabs the loop  4001  and pulls it through the second cannula  7000 . Once the loop  4001  is pulled through the second cannula  7000 , one end  8001  of a suture  8000  is passed through the loop  4001 . The one end  8001  of the suture  8000  is pulled through the labrum  2000  and first cannula  5000  via the loop  4001 , while the other end  8002  is grasped and pulled through the first cannula  5000  to have both ends  8001 ,  8002  exiting the cannula  5000 , as shown in  FIG. 17 . 
         [0086]    A hole  3001  is then made in the glenoid  3000  via the use of a drill guide  9000  and drill  10000 , as shown in  FIGS. 18 and 19 . The ends  8001 ,  8002  are placed through the suture threader loop  11000   b ,  12000   b  and pulled through the through hole  25 , 250  of the anchor  20 ,  200 , as shown in  FIGS. 20 and 21 . The suture  44 , 440  is removed from the delivery device  40 , 400  prior to inserting the anchor assembly  10 ,  100  into the hole  3001 . After the anchor assembly  10 ,  100  is inserted into the hole  3001 , as shown in  FIGS. 22 and 23 , the suture ends  8001 ,  8002  are tensioned and the ends  8001 ,  8002  are locked by placing the ends  8001 ,  8002  in the suture holder  45 ,  450 , as shown in  FIG. 24 , and the inner plug  30 ,  300  is then rotated, via rotation of the knob  43 ,  430  to fixate the suture  8000  in the cavity  23 ,  230 . 
         [0087]    The suture ends  8001 ,  8002  are cut, as shown in  FIG. 26 , and the delivery device  40 ,  400  is removed. Additional anchor assemblies  10 ,  100  may be inserted until the desired final repair is completed, as shown in  FIG. 27 . For clarity purposes, only end  8001 , suture loop  12000   b , and anchor assembly  100  are shown in  FIGS. 20-23 . However, in practice, both ends  8001 ,  8002  are used and suture loop  11000   b  and anchor assembly  10  may be used rather than suture loop  12000   b  and anchor assembly  100 . 
         [0088]      FIGS. 28-33  show an alternative embodiment of the anchor assembly  500  of the present disclosure and its components. The assembly  500  includes the anchor  600  and the insertion member  700 . The anchor  600  includes a proximal portion  610 , a distal portion  620 , and an inner cavity  630 . The inner cavity  630  will be further described below. An opening  640  to the cavity  630  is located at the proximal portion  610  of the anchor  600 . The anchor  600  also includes a transverse hole  650  extending through the anchor  600 . The through hole  650  is for housing of a flexible member, such as suture. Openings  650   a ,  650   b  are located at each end of the through hole  650 . The outer surface  670  of the proximal portion  610  also includes wings  680  for substantially reducing the possibility of removal of the anchor  600  when inserted into bone. The wings  680  are unlike barbs  28 ,  280  in that wings  680  are longer, have more space between them, and extend further upward and outward then barbs  28 ,  280 . The outer surface  670  also includes at least two slots  690  extending from the openings  650   a ,  650   b  of the through hole  650 . The slots  690  intersect the wings  680  and are configured for housing of the suture after positioning of the anchor  600  in bone. As shown in  FIG. 10 , the cavity  630  extends into and beyond the through hole  650  and includes a non-threaded proximal portion  630   a  and a threaded distal portion  630   b . The proximal portion  630   a  is square-shaped to correspond with an end of the delivery device used to insert the anchor  600  into bone, as will be further described below. The proximal portion  630   a  also has a larger diameter and is shorter than the distal portion  630   b.    
         [0089]    The insertion member  700  includes a body  710  having a threaded proximal portion  710   a  and a non-threaded distal portion  710   b . The proximal portion  710   a  has a larger diameter than the distal portion  710   b . The member  700  includes a triangular-shaped cannulation  710   e  that extends a partial length of the member  700 . The threads  710   a ′ are configured for engagement with the threads  630   c  of the cavity  630  when the insertion member  700  is arranged within the cavity  630 , as will be further explained below. 
         [0090]      FIGS. 34, 34A, 35, 35, 36, 36A-36B, and 37A-37B  show the delivery device  800  of the present disclosure. The device  800  includes a shaft  810 , a handle  820  coupled to the shaft  810 , and a knob  830  coupled to the handle  820 . The shaft  810  includes an outer member  810   a  and an inner member  810   b  slidably disposed within and coupled to the outer member  810   a . The inner member  810   b  includes a distal end  810   b ′ configured for disposal within the cannulation  710   e  of the insertion member  700  and a proximal end  810   b ″ coupled to the knob  830 . The end  810   b ′ is of a diameter such that it engages the wall  710   e ′ of the cannulation  710   e , thereby allowing movement of the member  700  when the knob  830  is rotated, as will be further described below. The outer member  810   a  includes a square-shaped tip  810   c  extending from a distal end  810   a ′ of the outer member  810   a  and a proximal end  810   a ″ coupled to the handle  820 . 
         [0091]    The handle  820  includes suture holders  850 , each suture holder  850  extending from a side of the handle  820 . Additionally, as shown in  FIG. 34 , a flexible member  900 , such as a suture, is housed within the through hole  650  with each end  900   a ,  900   b  of the member  900  being coupled to a holder  850 . The flexible member  850  helps to hold the anchor  600  on the device  800  prior to insertion of the anchor  600  into bone. The ends  900   a ,  900   b  of the suture  900  are also housed within channels  860  that extend along the shaft  810 . A suture threader  13000  is also releasably coupled to the shaft  81 . Threader  13000  includes a clip  13000   a  and a loop of suture  13000   b  coupled to the clip  13000   a . Suture loop  13000   b  is disposed within the through hole  650  and placed around the clip  13000   a . The delivery device  800  and its components, especially the knob  830 , are similar to the delivery device shown and described in the &#39;869 publication. 
         [0092]    As shown in  FIGS. 36 and 37 , the tip  810   c  is disposed within the proximal portion  630   a . Once the anchor assembly  500  is disposed within bone, the tip  810   c  helps to hold the anchor  600  stationary while the insertion member  700  is moved relative to the anchor  600 . Additionally, as shown in  FIG. 14A , the proximal end  810   b ″ of the inner member  810   b  includes threads  810   d  on an outer surface  810   e  of the inner member  810   b  and the proximal end  810   a ″ of the outer member  810   a  includes threads  810   f  on an inner surface  810   g  of the outer member  810   a . Threads  810   f  engage threads  810   d  to allow for coupling of the outer and inner members  810   a ,  810   b  and axial movement of the inner member  810   b  relative to the outer member  810   a.    
         [0093]    Axial movement of the inner member  810   b  relative to the outer member  810   a  allows for axial movement of the insertion member  700  to the two locations shown in  FIGS. 36B and 37B . Member  810   b  also includes a depth stop  810   b ′″ that engages an end  810   a ′″ of member  810   a , as shown in  FIG. 37A , once member  700  is located as shown in  FIG. 37B . Interaction of the depth stop  810   b ′″ with the end  810   a ′″ ceases axial movement of the member  700  toward the through hole  650  and prevents the member  700  from being overly inserted into the cavity  630 . The insertion member  700  is moved axially towards the through hole  650  to engage the flexible member and secure the flexible member within the cavity  630 , which will be further described below. 
         [0094]    During tissue repair via use of the anchor assembly  500  and the driver  800 , suture from a previously placed anchor is pulled through the through hole  650 . The manner in which the suture is pulled through the through hole  650  may be the same as the manner described in the &#39;106 and &#39;180 patent applications. The anchor assembly  500  is subsequently inserted into bone, via use of the driver  800 , in the manner shown in  FIG. 36B . Axial advancement of the anchor assembly  500  into the bone may occur via tapping on the handle  820 . After the soft tissue is situated on the bone and the suture is located through the soft tissue, in the manner described in the &#39;106 and &#39;180 patent applications, the insertion member  700  is moved axially towards the distal portion  630   b , via rotation of the knob  830  to engage the suture and secure the suture within the cavity  630 , in the manner shown in  FIG. 37B . For clarity purposes, only the anchor assembly  500  is shown in  FIGS. 36B and 37B . However, a further description and showing of a method of tissue repair similar to the above-described method, is shown in the &#39;106 and &#39;180 published applications. 
         [0095]    The components of the anchor assemblies  10 ,  100 ,  500  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. Furthermore, the outer surface  27 ,  270 ,  670  of the anchors  20 ,  200 ,  600  may include features other than barbs and wings  28 ,  280 ,  680  to reduce the possibility of removal of the anchor  20 ,  200 ,  600  and the barbs  28 ,  280 ,  680  may extend the entire length or a partial length of the anchor  20 ,  200 ,  600 . Similarly, the body  31 ,  310 ,  710  of the insertion member  30 ,  300 ,  700  and the cavity  23 ,  230 ,  630  of the anchor  20 ,  200 ,  600  may include features other than threads to facilitate insertion and removal of the insertion member  30 ,  300 ,  700  and the threads  31   a ′,  310   a ,  710   a ′ may extend the entire length or a partial length of the body  31 ,  310 ,  710  and cavity  23 ,  230 ,  630 . Also, for the purposes of this disclosure, the through hole  25 ,  250 ,  650  may be located anywhere along the length of the anchor  20 ,  200 ,  600 . Additionally, it is within the scope of this disclosure for the anchor  20 ,  200 ,  600  to have more or less than two slots  29 ,  290 ,  690 . 
         [0096]    Additionally, for the purposes of this disclosure, the outer member  41   a ,  410   a  includes at least one prong  41   c ,  410   c  and the anchor  20 ,  200  includes at least one corresponding depression  26 ,  260 . Also, the cannulation  31   e ,  310   e  of the insertion member  30 ,  300  may extend an entire length of the insertion member  30 , 300  and may include a shape other than triangular. 
         [0097]    The outer and inner members  41   a ,  41   b ,  410   a ,  410   b ,  810   a ,  810   b  of the delivery device  40 ,  400 ,  800  include a stainless steel material, but may be made from any other metal or non-metal material that is bio-compatible and strong enough to withstand the forces that are placed on the members  41   a ,  41   b ,  410   a ,  410   b ,  810   a ,  810   b  during surgery. The members  41   a ,  41   b ,  410   a ,  410   b ,  810   a ,  810   b  may be machined, die drawn and subsequently machined, or made by any other method known to one of skill in the art. The outer and inner members  41   a ,  41   b ,  410   a ,  410   b ,  810   a ,  810   b  are coupled to the handle  42 ,  420 ,  820  and knob  43 ,  430 ,  830  respectively, via a press-fit procedure. However, other methods of coupling the handle  42 ,  420 ,  820  and knob  43 ,  430 ,  830  to the members  41   a ,  41   b ,  410   a ,  410   b ,  810   a ,  810   b  are also within the scope of this disclosure. The handle  42 ,  420 ,  820  and knob  43 ,  430 ,  830  are of a non-metal material, but may be made from a metal material, and both are made via an injection molding process. However, other methods of making are also within the scope of this disclosure. 
         [0098]      FIGS. 38-40  show a first embodiment of a fenestrated suture anchor  1000  of the present disclosure. The anchor  1000  includes a body  1001  having a proximal portion  1001   a  and a distal portion  1001   b , a transverse through hole  1002  located between the distal and proximal portions  1001   b ,  1001   a , and a cavity  1003  extending a partial length of the body  1001 . Wings  1004  exist along the body  1001  and outward from it. Similar to the wings  680 , wings  1004  engage bone when the anchor  1000  is inserted into the bone, as will be further described below. The body  1001  also includes suture slots  1005  extending from openings  1002   a ,  1002   b  of the hole  1002 . Additionally, there are channels  1006  extending along the body  1001  on both sides of the slots  1005 . The channels  1006  extending from an outer surface  1007  of the anchor  1000  to the cavity  1003 , thereby allowing the anchor  1000  to be fenestrated. The channels  1006  allow for ingrowth of tissue, such as bone, and other nutrients after insertion of the anchor  1000  into bone, as will be further described later. A suture  1008  is housed within the hole  1002  having its ends  1008   a ,  1008   b  housed within the slots  1005 . 
         [0099]      FIGS. 41-42  show a second embodiment of a fenestrated suture anchor  1100 . The anchor  1100  includes a body  1101  having a proximal portion  1101   a  and a distal portion  1101   b , a transverse through hole  1102  located between the distal and proximal portions  1101   b ,  1101   a , and a cavity  1103  extending a partial length of the body  1101 . Barbs  1104  exist along the body  1101  and extend outward from it. Similar to the barbs  28 ,  280 , barbs  1104  engage bone when the anchor  1100  is inserted into the bone, as will be further described below. The body  1101  also includes channels  1106  extending along the body  1101 . The channels  1106  extending from an outer surface  1107  of the anchor  1100  to the cavity  1103 , thereby allowing the anchor  1100  to be fenestrated. The channels  1106  allow for ingrowth of tissue, such as bone, and other nutrients after insertion of the anchor  1100  into bone, as will be further described later. A suture  1108  is housed within the hole  1102  having its ends  1108   a ,  1108   b  extend through openings  1102   a ,  1102   b  and then back through the cavity  1103 , as shown in  FIG. 41 . 
         [0100]      FIGS. 43-44  show a first embodiment of a fenestrated suture anchor  1200  of the present disclosure. The anchor  1200  includes a body  1201  having a proximal portion  1201   a  and a distal portion  1201   b , a transverse through hole  1202  located between the distal and proximal portions  1201   b ,  1201   a , and a cavity  1203  extending a partial length of the body  1201 . Barbs  1204  exist along the body  1201  and extend outward from it. Similar to the barbs  28 ,  280 , barbs  1204  engage bone when the anchor  1200  is inserted into the bone, as will be further described below. The body  1201  also includes suture slots  1205  extending from openings  1202   a ,  1202   b  of the hole  1202 . Additionally, there are channels  1206  extending along the body  1201  interspaced with the slots  1205 . The channels  1206  extend from an outer surface  1207  of the anchor  1200  to the cavity  1203 , thereby allowing the anchor  1200  to be fenestrated. The channels  1206  allow for ingrowth of tissue, such as bone, and other nutrients after insertion of the anchor  1200  into bone, as will be further described later. A suture  1208  is housed within the hole  1202  having its ends  1208   a ,  1208   b  housed within the slots  1205 . 
         [0101]    During repair of tissue via use of the suture anchors  1000 ,  1100 ,  1200 , a delivery device having a handle and a shaft may be used to deliver the anchors into bone. An end of the shaft may be inserted into the cavity of the anchors and may have the same shape as cavity. The anchors  1000 ,  1100 ,  1200  are designed to be inserted into bone via axial motion. The torn tissue may then be placed on the bone, adjacent the anchors  1000 ,  1100 ,  1200 . Subsequently, the suture may then be pulled through the tissue and tied to attach the tissue to the bone. A hole may be drilled in the bone prior to inserting the anchors  1000 ,  1100 ,  1200  into the bone. 
         [0102]      FIGS. 45-50  show anchor assemblies  1300 ,  1400 ,  1500  similar to the anchor assemblies  10  of  FIGS. 1, 8, and 28 . The anchor assemblies  1300 ,  1400 ,  1500  are similar to the anchor assemblies  10 ,  100 ,  500  of  FIGS. 1, 8, and 28  and the anchor assemblies shown and described in US Patent Application Publication No. 20090112270, the disclosure of which is incorporated herein by reference in its entirety, and the &#39;869 publication mentioned above.  FIGS. 45-50  only show the anchors  1310 ,  1410 ,  1510  of the assemblies  1300 ,  1400 ,  1500 . Although for the purposes of this disclosure, an insertion member, similar to the insertion members shown in the above mentioned figures and publications, would also be used with the anchors  1310 ,  1410 ,  1510 . However, it is possible that the anchors  1310 ,  1410 ,  1510  could be used without insertion members, thereby being used in a similar manner to anchors  1000 ,  1100 ,  1200  during surgery. 
         [0103]      FIGS. 45-46  show an anchor  1310  having barbs  1320  that extend outward from the body  1330  of the anchor  1310  and along its entire length on both sides. The barbs  1320  alternate in direction along the length of the anchor  1310 . Similar to wings  680 , extending the barbs  1320  outward from the body  1330  increases the overall surface area of the barbs  1320  and allows flexibility, which improves resistance to anchor pull-out, thereby reducing the possibility of removal of the anchor  1300  when inserted into bone.  FIGS. 47-50  show anchors  1410 ,  1510 , which include barbs  1420 ,  1520 , similar in design and orientation, to barbs  1320  of anchor  1310 . Unlike anchor  1310 , the barbs  1420 ,  1520  do not extend along the entire length of the anchor  1410 ,  1510  and the distal end  1440 ,  1540  of the anchor  1410 ,  1510  is pointed thereby making it possible to insert the anchor  1410 ,  1510  into bone without first creating a hole in the bone. 
         [0104]      FIGS. 51 and 52  show an anchor  1610  that includes an outer body  1620  and an inner body  1630  disposed within the outer body  1620 . The outer body  1620  includes an outer surface  1621  having wings  1622 , similar to wings  680 , and an inner cavity  1623 . The distal end  1624  of the inner cavity  1623  includes a first feature  1625  and a second feature  1626 , which will be more fully explained below in relation to the inner body  1630 . Similar to the anchors described above, the outer body  1620  also includes a transverse hole  1627  and slots  1628 . Similar to the anchors described above, the inner body  1630  includes a threaded inner cavity  1631 , a through hole  1632 , a proximal portion  1633 , and a distal portion  1634 . The inner body  1630  includes a first feature  1635  and a second feature  1636 , both of which are located between the proximal and distal portions  1633 ,  1634  and which will be more fully explained below in relation to the outer body  1620 . The inner body  1630  is disposed within the outer body  1620  such that the outer body first feature  1625  is located within the inner body first feature  1635  and the outer body second feature  1626  is located within the inner body second feature  1636 . The first features  1625 ,  1635  are shaped so as to substantially reduce the possibility of the inner body  1630  rotating in relation to the outer body  1620  during repair, as will be more fully described below. The second features  1626 ,  1636  are shaped so as to substantially reduce the possibility of the inner body  1630  from moving axially in relation to the outer body  1620  during insertion of the anchor  1610  into bone, as will be more fully described below. Additionally, the through holes  1627 ,  1632  are aligned. 
         [0105]    Similar to anchors  1310 ,  1410 ,  1510 , anchor  1610  is part of an anchor assembly. However, for clarity purposes, the anchor  1610  is shown without an inner member. The distal portion  1634  of the inner body  1630  is pointed and the proximal portion  1633  does not extend the entire length of the inner cavity  1623 , the purposes of which will be described later. 
         [0106]    During insertion of the anchor  1610  into bone, a delivery device  1700 , similar to delivery device  800 , is used. For clarity purposes, only the outer member  1710   a  of the shaft  1710  is shown in  FIGS. 51 and 52 . The outer member  1710   a  is inserted into the anchor  1610  such that the square-shaped tip  1710   c  is inserted into the inner cavity  1623 . The tip  1710   c  engages the inner body  1630  such that there is a clearance  1800  between the distal end  1710   a ′ of the shaft  1710  and the anchor  1610 . During insertion of the anchor  1610  into bone, the outer member  1710   a  only engages the inner body  1630 , thereby asserting all of the axial force of the outer member  1710   a  on the inner body  1630 , rather than the outer body  1620 . The cooperation of the second features  1626 ,  1636  substantially reduces the possibility of the inner body  1630  becoming unlocked from the outer body  1620  during axial insertion of the anchor  1610  into the bone. After insertion of the anchor  1610  into bone, a threaded inner member is rotationally inserted into the cavity  1631  via the use an inner member on the delivery device  1700 , similar to the method of repair described above. During rotational insertion of the inner member into the cavity  1631 , the cooperation of the first features  1625 ,  1635  substantially reduces the possibility of rotation of the inner body  1630  in relation to the outer body  1620 . The pointed distal portion  1634  of the inner body  1630  allows for insertion of the anchor  1610  into bone without having to create a hole in the bone prior to insertion. 
         [0107]    For the purposes of this disclosure, the inner body  1630  is made from a metal material and the outer body  1620  is made from a polymer material. The outer and inner bodies  1620 ,  1630  are coupled to each other via an interference fit or overmolding. However, other materials and manners of coupling may be used. 
         [0108]      FIGS. 53 and 54  show an anchor  1900  similar to the anchor  600 , albeit with a distal portion  1920  that is pointed enough to allow for insertion of the anchor  1900  into bone without first creating a hole in bone. 
         [0109]    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.
