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.
1. An anchor for placement in or against tissue, the anchor having an undeployed state and a deployed state, the anchor comprising:
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.
2. The anchor of claim 1 , wherein the flat fibrous construct comprises a lumen and wherein the fibrous construct is tubular.
3. The anchor of claim 1 , wherein when the anchor is in the deployed state:
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 anchor of claim 1 , further comprising an intermediate location at which the filament passes through the flat fibrous construct.
5. An anchor placement system comprising:
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; and
an installation device including an end around which the filament is positioned, the flat fibrous construct also being positioned around the end of the installation device between the end of the installation device and the filament.
6. The anchor placement system of claim 5 , the end of the installation device comprising a fork around which the filament and the flat fibrous construct are positioned with the flat fibrous construct being positioned around the fork between the fork and the filament.
7. The anchor placement system of claim 6 , the first end and the second end of the flat fibrous construct extending along opposite sides of the installation device, wherein a distance from the filament positioned around the fork to the first end of the fibrous construct is between 7.5 mm to 15 mm.
8. The anchor placement system of claim 6 , the first end and the second end of the flat fibrous construct extending along opposite sides of the installation device, wherein a distance from a distal end of the fork to the first end of the fibrous construct is between 8.5 mm to 17 mm.
9. The anchor placement system of claim 5 , wherein the flat fibrous construct comprises a lumen and wherein the fibrous construct is tubular.
10. The anchor placement system of claim 5 , wherein when the anchor is in the deployed state:
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.
11. The anchor placement system of claim 5 , further comprising an intermediate location at which the filament passes through the flat fibrous construct.
