First Claim
Patent Images
1. A connector, comprising:
- a body;
a first opening in the body;
a second opening in the body; and
a cam system positioned in a cam system opening in the body,wherein the cam system is in communication with the first opening,wherein the cam system comprises an engager that is extendable into the first opening of the body to engage an elongated member,wherein the cam system opening comprises a shoulder that inhibits removal of the cam system from the cam system opening and a cam guide that limits rotational motion of the cam system within the cam system opening, andwherein the longitudinal axis of the cam system is angled at an angle between about 40° and
about 90°
with respect to the longitudinal axis of the body.

Abstract
A transverse connector may be attached to rods of an orthopedic stabilization system by cam locks. Rotation of a cam system may extend a rod engager into a rod opening. The rod engager may be a portion of the cam system. The extension of the rod engager into the rod opening may push a rod against a body of the transverse connector to form a frictional engagement between the transverse connector, the rod, and the rod engager. The cam system allows the formation of an un-threaded, unitary transverse connector that has a low profile. The transverse connector may be easily and securely attached to a rod.

25. A bone stabilization system, comprising:
-
a first elongated member coupled to a first fixation element; a second elongated member positioned adjacent to the first elongated member and coupled to a second fixation element; and a connector comprising; a first section and a second section connected via a fastening system, wherein the first section comprises; a first opening configured to accept the first elongated member; a cam system in communication with the first opening; a cam system opening in the connector, the cam system opening comprising a shoulder that inhibits removal of the cam system from the cam system opening and a cam guide that limits rotational motion of the cam system within the cam system opening; wherein a position of the first section is adjustable relative to the second section, and wherein the fastening system inhibits movement of the first section relative to the second section during use, the fastening system comprising a collet and a collar, and wherein the collar is friction locked to the collet to inhibit movement of the first section relative to the second section. - View Dependent Claims (26, 27, 28, 29, 30)

31. A transverse connector comprising:
-
a body comprising a first section and a second section, wherein a position of the first section is adjustable relative to the second section, and further comprising a fastening system configured to fix the position of the first section relative to the second section during use, the fastening system comprising a collet and a collar, and wherein the collar is compressed onto the collet to fix the position of the first section relative to the second section; a first opening in the body configured to accept an elongated member; a cam system positioned in a cam system opening in the body, wherein the cam system is in communication with the first opening and wherein the cam system opening comprises a shoulder that inhibits removal of the cam system from the cam system opening and a cam guide that limits rotational motion of the cam system within the cam system opening; and an engager configured to extend into the first opening to couple the elongated member to the body when the cam system is activated. - View Dependent Claims (32, 33, 34, 35)
