May - Web page: https://patentgrep.com/patent/US10368916B2 ## CPC - A61B 17/7035: {Screws or hooks, wherein a rod-clamping part and a bone-anchoring part can pivot relative to each other} - A61B: DIAGNOSIS; SURGERY; IDENTIFICATION (usefulness limited to only animals A61D) ## Abstract A bone fastener comprises a first member that defines an implant cavity. A part is disposed with the first member. A retainer is connected with the part and the first member, and includes an expandable orientation and a non-expandable orientation. A second member is connectable to the retainer and configured to penetrate tissue. Implants, systems, instruments and methods are disclosed. ## Claims ### Claim 1 A bone fastener comprising: a first member defining an implant cavity and having a threaded inner surface; a part disposed with the first member; a retainer connected with the part and the first member, and including a threaded outer surface configured for engagement with the threaded inner surface of the first member to move the retainer between an expandable orientation and a non-expandable orientation; and a second member connectable to the retainer and configured to penetrate tissue, wherein the first member defines a groove configured for disposal of a band, and wherein the retainer is engageable with the part and the first member in the expandable orientation such that the retainer engages the band to provisionally connect the retainer with the first member and in the non-expandable orientation such that the retainer is fixed with the first member. ### Claim 2 (depends on 1) A bone fastener as recited in claim 1, wherein the part includes at least one mating element that interfaces with a surgical instrument for rotation thereof. ### Claim 3 (depends on 1) A bone fastener as recited in claim 1, wherein the part includes an inner surface that defines a plurality of circumferentially disposed recesses. ### Claim 4 (depends on 1) A bone fastener as recited in claim 1, wherein the part includes a plurality of spaced apart flanges that matingly engage notches in the retainer to connect the part and the retainer such that the part drives and rotates the retainer between the expandable orientation and the non-expandable orientation. ### Claim 5 (depends on 1) A bone fastener as recited in claim 1, wherein the part includes spaced apart circumferential outer flanges engageable with the retainer. ### Claim 6 (depends on 1) A bone fastener as recited in claim 1, wherein the retainer is simultaneously rotatable with the part. ### Claim 7 (depends on 1) A bone fastener as recited in claim 1, wherein the retainer is rotatable relative to the first member for fixation therewith. ### Claim 8 (depends on 1) A bone fastener as recited in claim 1, wherein the part includes an outer surface that is free of threads. ### Claim 9 (depends on 1) A bone fastener as recited in claim 1, wherein the retainer is expandable between a capture orientation with the second member and an expanded orientation. ### Claim 10 (depends on 1) A bone fastener as recited in claim 1, wherein the retainer includes a circumferential sleeve that defines at least one gap. ### Claim 11 (depends on 1) A bone fastener as recited in claim 1, wherein the retainer defines a plurality of spaced apart concave notches and the part comprises a plurality of spaced apart convex flanges that matingly engage the notches to connect the part and the retainer such that the part drives and rotates the retainer between the expandable orientation and the non-expandable orientation. ### Claim 12 (depends on 1) A bone fastener as recited in claim 1, wherein the retainer is manually engageable with the second member in a non-instrumented assembly. ### Claim 13 (depends on 1) A bone fastener as recited in claim 1, wherein the second member is spaced apart from the first member by the part and the retainer. ### Claim 14 (depends on 1) A bone fastener as recited in claim 1, wherein the retainer comprises opposite proximal and distal surfaces, the proximal surface directly engaging a shoulder of the first member when the retainer is in the non-expandable orientation to prevent the retainer from translating axially relative to the first member in one direction. ### Claim 15 (depends on 1) A bone fastener as recited in claim 1, wherein the part comprises opposite proximal and distal surfaces, the proximal surface directly engaging a shoulder of the first member when the retainer is in the non-expandable orientation to prevent the part from translating axially relative to the first member in one direction. ### Claim 16 A bone fastener comprising: an implant receiver; a crown disposed with the implant receiver; a collet connected with the crown and including a threaded outer surface configured for engagement with a threaded inner surface of the implant receiver to translate the collet relative to the implant receiver between an open position and a closed position; and a screw shaft engageable with the collet and configured to penetrate tissue, wherein the implant receiver defines a groove configured for disposal of a band, and wherein the collet is engageable with the crown and the implant receiver in the open position such that the collet engages the band to provisionally connect the collet with the implant receiver and in the closed position such that the collet is fixed with the implant receiver. ### Claim 17 (depends on 16) A bone fastener as recited in claim 16, wherein the collet is expandable between a capture orientation with the screw shaft and an expanded orientation. ### Claim 18 (depends on 16) A bone fastener as recited in claim 16, wherein the collet is simultaneously rotatable with the crown. ### Claim 19 A bone fastener comprising: an implant receiver; a crown disposed with the implant receiver, the crown including an inner surface that mates with a surgical instrument and outer flanges; a collet comprising notches engaged with the flanges to connect the crown and the collet such that the crown drives and rotates the collet between an expandable orientation and a non-expandable orientation, the collet comprising a threaded outer surface configured for engagement with a threaded inner surface of the implant receiver to translate the collet relative to the implant receiver between the expandable orientation and the non-expandable orientation; and a screw shaft connectable to the collet and configured to penetrate tissue, wherein the implant receiver defines a groove configured for disposal of a band, and wherein the collet is engageable with the crown and the implant receiver in the expandable orientation such that the collet engages the band to provisionally connect the collet with the first member. ### Claim 20 (depends on 19) A bone fastener as recited in claim 19, wherein the collet is engageable with the crown and the implant receiver in the non-expandable orientation such that the collet is fixed with the implant receiver.
