Abstract
Suture constructs and methods for soft tissue to bone repairs. The suture construct is a soft, suture-based anchor which is self-cinching and has a specific, accordian-type configuration (i.e., with the ability to fold from a first, extended position to a second, folded or compressed position). The suture-based anchor may be formed essentially of a flexible material such as a high strength surgical suture, suture chain, or suture.
Claims21
An anchor construct configured to be anchored in bone, the anchor construct comprising:
- a substantially flat suture tape section having an axis of extension, a width in a first direction perpendicular to the axis of extension and a thickness that is smaller than the width in a second direction perpendicular to the axis of extension;
- and
- a first suture section and a second suture section each attached to and extending from the suture tape section and having a substantially uniform thickness in every direction perpendicular to the axis of extension, wherein the second suture section is threadable through or around tissue for holding the tissue against bone;
- wherein the first suture section defines two apertures spaced apart axially along a length of the first suture section and a channel that extends through the length to connect the two apertures, and wherein the second suture section is configured to pass through the channel of the first suture section to form a splice and an adjustable knotless self-locking loop, with a portion of the first suture section that defines the channel forming at least part of the loop wherein pulling the second suture section through the channel of the first suture section tightens the adjustable knotless self-locking loop on the tissue thereby securing the tissue to the bone.

An anchor construct configured to be anchored in bone, the anchor construct comprising:
- an integrally connected suture having an axis of extension and comprising:
- a substantially flat suture tape section having a width in a first direction perpendicular to the axis of extension, and a thickness that is smaller than the width in a second direction perpendicular to the axis of extension;
- and
- a suture section having a substantially uniform thickness in every direction perpendicular to the axis of extension;
- wherein a first part of the suture section has a coreless section formed by two apertures spaced apart axially along a length of the suture and a channel that extends through the length to connect the two apertures, while at least a majority of the suture tape section has a solid core, and wherein another portion of the anchor construct is configured to pass through the channel to form a splice and an adjustable knotless self-locking loop, the splice forming a finger-trap mechanism where the entire length of the suture that defines the channel is configured to apply tension to the another portion of the anchor construct that passes therethrough when a force is applied to the loop wherein the another portion of the anchor construct is threadable through or around tissue for holding the tissue against bone, and wherein pulling the another portion of the anchor construct through the channel of the first part of the suture section tightens the adjustable knotless self-locking loop on the tissue thereby securing the tissue to the bone.

- a first suture section having a substantially uniform thickness in every direction perpendicular to the axis of extension;
- and
- a second suture section that defines two apertures spaced apart axially along a length of the second suture section and a channel that extends through the length to connect the two apertures;
- wherein in a first configuration, the channel of the second suture remains free from any other portion of the anchor construct passing therethrough, and wherein in a second configuration, another portion of the anchor construct is passed through the channel to form a splice and an adjustable knotless self-locking loop, with a portion of the second suture section that defines the channel forming at least part of the loop wherein the first suture section is threadable through or around tissue for holding the tissue against bone;
- wherein pulling the first suture section through the channel of the second suture section tightens the adjustable knotless self-locking loop on the tissue thereby securing the tissue to the bone.
