Orthopedic anchoring system and methods
First Claim
1. An orthopedic anchoring system comprising:
- an implant assembly comprising;
an implant body comprising at least a portion of a locking element comprising a slot having lateral sides formed in the implant body;
an implant outer layer comprising a longitudinal axis and a lumen extending parallel to the longitudinal axis, wherein the lumen is configured to receive at least a portion of the implant body within the lumen; and
a fastener comprising an attachment feature configured to mechanically interlock with the locking element in a force-fit mechanical engagement, the attachment feature comprising a fastener distal end attached to the fastener by a contracted neck region, wherein the fastener distal end is configured to be forced through the slot to produce the force-fit mechanical engagement between the lateral sides of the slot and the fastener distal end;
a delivery tool comprising;
an implant guide configured to releasably couple to at least one of the implant body or the implant outer layer; and
a fastener guide operably coupled to the implant guide and configured to deliver the attachment feature of the fastener to the locking element;
wherein a final manufactured configuration of the delivery tool and a final manufactured configuration of the implant assembly are such that, when the system is assembled such that the implant guide is releasably coupled to at least one of the implant body or the implant outer layer, a delivery arrangement automatically exists such that the fastener guide is correctly oriented to deliver the attachment feature to the locking element.

Abstract
Systems and methods for performing orthopedic surgical procedures to treat a patient are presented herein. The orthopedic anchoring system may include an implant assembly and a delivery tool to perform the orthopedic surgical procedure. The implant assembly may include an implant outer layer, an implant body situated within the implant outer layer, and a fastener attached to a locking element of the implant body. The delivery tool may include a targeting arm, a fastener guide removably attached at a first end of the targeting arm and an implant guide removably attached to a second end of the targeting arm. The delivery tool may maintain a fixed spatial relationship between a longitudinal axis of the fastener and a longitudinal axis of the implant outer layer and implant body. The orthopedic anchoring system may be used to perform orthopedic surgical procedures related to joint reinforcement or immobilization.

14. An orthopedic anchoring system comprising:
-
an implant assembly comprising; an implant body comprising at least a portion of a locking element comprising a slot formed within the implant body; an implant outer layer comprising a longitudinal axis and a lumen extending parallel to the longitudinal axis, wherein the lumen is configured to receive at least a portion of the implant body within the lumen; and a fastener comprising an attachment feature configured to mechanically interlock with the locking element in an interference mechanical engagement, the attachment feature comprises a fastener distal end attached to the fastener by contracted neck region, the locking element extending from a distal end of the implant body in a direction parallel with the longitudinal axis, wherein the slot comprises a slot width between a diameter of the neck region and a diameter of the fastener distal end, the slot is configured to receive the neck region of the attachment feature to retain the fastener distal end and to produce the interference mechanical engagement; a delivery tool comprising; an implant guide configured to releasably couple to at least one of the implant body or the implant outer layer; and a fastener guide operably coupled to the implant guide and configured to deliver the attachment feature of the fastener to the locking element; wherein a final manufactured configuration of the delivery tool and a final manufactured configuration of the implant assembly are such that, when the system is assembled such that the implant guide is releasably coupled to the implant body, a delivery arrangement automatically exists such that the fastener guide is correctly oriented to deliver the attachment feature to the locking element. - View Dependent Claims (15, 16, 17, 18, 20, 21, 22, 23, 24, 25, 26)

27. An orthopedic anchoring system comprising:
-
an implant assembly comprising; an implant body comprising at least a portion of a locking element; an implant outer layer comprising a longitudinal axis and a lumen extending parallel to the longitudinal axis, wherein the lumen is configured to receive at least a portion of the implant body within the lumen, the implant outer layer further comprises a first alignment feature formed on the inner surface of the lumen, an exterior surface, a fastener opening, a fastener opening perimeter; and a fastener comprising an attachment feature configured to mechanically interlock with the locking element in an interference mechanical engagement, the attachment feature comprising a distal end attached to the fastener by a contracted neck region; a delivery tool comprising; an implant guide configured to releasably couple to at least one of the implant body or the implant outer layer; and a fastener guide operably coupled to the implant guide and configured to deliver the attachment feature of the fastener to the locking element; wherein a final manufactured configuration of the delivery tool and a final manufactured configuration of the implant assembly are such that, when the system is assembled such that the implant guide is releasably coupled to at least one of the implant body or the implant outer layer, a delivery arrangement automatically exists such that the fastener guide is correctly oriented to deliver the attachment feature to the locking element, wherein the fastener opening communicates between the exterior surface and the lumen through a lumen wall and is configured to provide a path through which the attachment feature passes to engage the locking element in the interference mechanical engagement; the implant body further comprises a second alignment feature formed on an exterior surface of the implant body configured to operatively engage with the first alignment feature; the locking element comprises a slot formed through the implant body at a distal region of the implant body, wherein the slot comprises a first end and a second end opposite the first end, a first slot side and a second slot side opposite the first slot side, each of the first and second slot sides attached to the first end and toward the second slot end, a slot width extending between the first slot side and second slot side near a first slot end and dimensioned to include a width which is between a diameter of the contracted neck region and a diameter of the distal end of the attachment feature of the fastener; and
the slot is configured to receive the contracted neck region of the attachment feature to retain the distal end of the attachment feature and to produce the interference mechanical engagement; andwherein, when the implant assembly transitions from a first or open condition to a second or locked condition, the first alignment feature being operatively connected to the second feature results in a predetermined alignment of both the implant body relative to the implant outer layer and the slot relative to a position of the attachment feature when received within the lumen through the fastener opening such that the slot and the attachment feature mechanically interlock once in the second or locked condition, the first or open condition being when the locking element does not engage the attachment feature and the second or locked condition being when the locking element engages the attachment feature. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
