Soft anchor made from suture filament and suture tape
An anchor is provided for placement in or against tissue. The anchor includes a flat fibrous construct having a first end and a second end; and a filament having a first end and a second end passing through the fibrous construct in two locations including a first passing location nearest a first end of the fibrous construct, a second passing location nearest a second end of the fibrous construct, the filament remaining free to slide through the first passing location and the second passing location such that the filament can be removed from the flat fibrous construct from the first end of the fibrous construct and the second end of the fibrous construct. The anchor can be inserted into a bone hole and deployed.
1. A method of anchoring tissue to bone, comprising the steps of:
providing an anchor having an undeployed state and a deployed state, the anchor including:
a flat fibrous construct having a first end and a second end, wherein:
in the undeployed state, the fibrous construct has a first fibrous construct width or thickness and a first fibrous construct length;
in the deployed state, the fibrous construct has a second fibrous construct width or thickness and a second fibrous construct length; and
the second fibrous construct width or thickness being greater than the first fibrous construct width or thickness, the second fibrous construct length being shorter than the first fibrous construct length; and
a filament having a first end and a second end passing through the fibrous construct in two locations including a first passing location nearest a first end of the fibrous construct, a second passing location nearest a second end of the fibrous construct, the filament remaining free to slide through the first passing location and the second passing location such that the filament can be removed from the flat fibrous construct from the first end of the fibrous construct and the second end of the fibrous construct;
inserting the anchor into a hole in a bone; and
deploying the anchor into the hole.
2. The method of claim 1 , wherein the flat fibrous construct comprises a lumen and wherein the fibrous construct is tubular.
3. The method of claim 1 , wherein when the anchor is in the deployed state after the step of deploying:
the filament forms a semi-u-shape construct with an interior surface forming an interior space within a bone hole; and
the first end and the second end of the flat fibrous construct is positioned within the interior space.
4. The method of claim 1 , the filament having a longitudinal axis, the flat fibrous construct comprising:
a first state in which the flat fibrous construct is uncompressed and extends along the longitudinal axis of the filament; and
a second state in which the flat fibrous construct is compressed and expanded in a direction perpendicular to longitudinal axis of the filament.
