Abstract
The present disclosure relates to an anchor assembly. The anchor assembly includes an anchor defining a cavity and an opening to the cavity; and a headless insertion member configured for arrangement within the anchor cavity, the insertion member including a body having a threaded proximal portion, a non-threaded distal portion, and a cannulation extending a partial length of the insertion member. Other anchor assemblies, anchors, and delivery devices are also disclosed.
Claims29
An anchor assembly comprising:
- an anchor body defining a cavity extending from a proximal end of the anchor, a plurality of wings extending from an outer surface of the body, a tapered distal end and a through hole intersecting the cavity so as to define first and second openings on opposing sides of the cavity;
- and
- a headless insertion member including a cannulation extending a substantial length of the insertion member and threads located along an outer surface of the insertion member extending from an insertion member proximal end;
- and the anchor cavity includes threads that extend along a length of the cavity, wherein the insertion member threads and cavity threads are configured to engage each other and move the insertion member so as to cover the first and second openings when the insertion member is located in a suture fixation position, and wherein the anchor assembly is configured for a suture to be inserted into the through hole, the insertion member disposed within the cavity and proximal the through hole during placement of the suture within the through hole;
- wherein the insertion member has a distal portion that defines a length having a diameter along the entire distal portion length that is smaller than a diameter of a proximal portion of the insertion member, and wherein the distal portion length covers the through hole from a point proximal of a proximal edge of the through hole to a point distal of a distal edge of the through hole when the insertion member covers the first and second openings.

An anchor assembly comprising:
- an anchor defining a cavity including threads extending along a length of the cavity, and a through hole intersecting the cavity and proximally spaced from the cavity bottom surface, defining first and second openings on opposing sides of the cavity;
- and
- a headless, insertion member including a threaded outer surface and a cannulation extending a substantial length of the insertion member, the threaded outer surface configured to engage the anchor cavity threads and move the insertion member so as to cover the first and second openings when the insertion member is in a suture fixation position;
- and wherein the insertion member includes a proximal portion having an opening and a flat distal portion, the flat distal portion located opposite the bottom portion of the cavity;
- wherein the insertion member includes a typical outer body diameter that is smaller than a diameter of any threads on the insertion member and larger than a maximum dimension of the first and second openings, and wherein the typical outer body diameter of the insertion member entirely covers the first and second openings in a suture fixation position.

An anchor assembly comprising:
- an anchor body defining two rows of axially spaced wings on an outer surface of the anchor body, a proximal opening to the cavity, the cavity including threads, a through hole located through the anchor cavity, the through hole proximally spaced from a cavity bottom surface, the through hole defining first and second openings on opposing sides of the cavity;
- and
- a headless, cannulated insertion member including threads extending along an outer surface of the insertion member extending from a proximal end, the insertion member threads configured to engage threads of the anchor cavity and move the insertion member so as to cover the first and second openings when the insertion member is located in a suture fixation position;
- and wherein the anchor assembly is configured for a suture to be disposed within the through hole with the insertion member disposed within the anchor cavity and adjacent the through hole;
- wherein the insertion member has a distal portion that defines a smaller diameter than a diameter of a proximal portion of the insertion member, the distal portion defining a length that covers the through hole from a point proximal of a proximal edge of the through hole to a point distal of a distal edge of the through hole when the insertion member covers the first and second openings.
