Devices, systems, and methods for repairing soft tissue and attaching soft tissue to bone
Devices, systems and/or methods for fixating soft tissue to bone are provided. In one embodiment, a repair device for fixating soft tissue to bone with a bone anchor includes a soft tissue anchor and one or more flexible members. The soft tissue anchor includes a base with multiple legs extending from the base. The one or more flexible members are coupled to the base and configured to extend from the base to the bone anchor with a fixed length. With this arrangement, the fixed length of the one or more flexible members is configured to maintain a substantially fixed pre-determined distance between the soft tissue anchor and the bone anchor such that, as the bone anchor is seated into bone, the one or more flexible members pulls the soft tissue anchor down against the soft tissue to fixate the soft tissue to the bone.
1. A medical device system for fixating soft tissue to bone, the medical device system comprising:
a delivery instrument having an elongated portion defining a delivery instrument axis, the delivery instrument including a distal impacting surface; and
a repair device system configured to be removably coupled to the delivery instrument, the repair device system including:
a bone anchor having an elongated structure extending between a proximal end and a distal end, the bone anchor defining a bone anchor axis extending along the elongated structure;
a soft tissue anchor having a base with multiple legs extending from the base, the base defining a central opening defining a tissue anchor axis; and
one or more flexible members extending to couple the soft tissue anchor to the bone anchor;
wherein the repair device system is removably coupled to the delivery instrument with the elongated portion extending through the central opening of the soft tissue anchor and the distal impacting surface abutted against the proximal end of the bone anchor such that, as the bone anchor is being implanted into bone, the one or more flexible members extend taut between the bone anchor and the soft tissue anchor to simultaneously pull the soft tissue anchor into the soft tissue.
2. The medical device system of claim 1 , wherein the repair device system is configured to be delivered with the delivery instrument such that the delivery instrument axis is substantially coaxial, or substantially parallel, with the bone anchor axis and the tissue anchor axis.
3. The medical device system of claim 1 , wherein, as the bone anchor is seated into bone with the delivery instrument, the one or more flexible members maintain a substantially fixed distance between the bone anchor and the soft tissue anchor.
4. The medical device system of claim 1 , wherein, as the bone anchor is seated into bone with the delivery instrument, the soft tissue anchor compresses soft tissue against the bone with the one or more flexible members coupled to the soft tissue anchor.
5. The medical device system of claim 1 , wherein the one or more flexible members are a fixed length such that, upon the one or more flexible members being in a taut position, the one or more flexible members maintain a substantially fixed distance between the bone anchor and the soft tissue anchor in a pre-delivered state and a delivered state.
6. The medical device system of claim 1 , further comprising a retainer element, the retainer element having a line and a retaining portion, the line extending along an underside of the soft tissue anchor and toward the retaining portion, the retaining portion being removably coupled to the delivery instrument and configured to retain the line thereto.
7. The medical device system of claim 1 , further comprising a retainer element sized and configured to removably couple the delivery instrument to the repair device system, the retainer element having a line configured to be positioned along an underside of the soft tissue anchor to position the one or more flexible members in a taut position.
8. The medical device system of claim 1 , wherein the bone anchor defines a hole in the proximal end of the bone anchor, the hole sized and configured to receive an alignment portion extending from adjacent the distal impacting surface of the delivery instrument.
