Rod coupling system and devices and methods of making and using the same
First Claim
1. A rod coupler system comprising:
- a coupling body having a bone fastener disposed therethrough,a first saddle detachably attached to a locking cap, the first saddle having a concave portion configured to abut an elongate rod along at least two lines of contact between said first saddle and said elongate rod, anda second saddle having a first side abutting said bone fastener within said coupling body, and a second side of said saddle opposite said first side, said second side having a concave portion configured to abut the elongate rod along at least two lines of contact between said second saddle and said elongate rod,wherein in a first assembled position, the first saddle is attached to the locking cap and in a second assembled position, the first saddle is not attached to the locking cap.

Abstract
Provided are rod coupler devices, systems, kits and methods, which include at least one saddle having a concave configuration that either abuts a bone fastener and/or a locking cap and is shaped so as to contact the rod in two or more lines of contact, which reduces pressure on the rod, and therefore permits use of a rod having various materials, such as PEEK, without significant deformation of the rod. Also provided is the saddle itself and integrated locking caps that include a saddle, the locking cap and a set screw. Also provided are elongate rods having advantageous shapes, configurations, and/or compositions for rod coupler devices, systems and methods. Further provided are screw and cap devices and systems that themselves include a concave configuration so as to contact a rod in two or more lines of contact, which reduces pressure on the rod.

9. A coupling system comprising:
-
a saddle comprising; a first side detachably attached to a locking cap for a coupling body; and a second side opposite said first side of said saddle, said second side having a concave portion configured to abut an elongate rod along at least two lines of contact between said saddle and said elongate rod, wherein in a first assembled position where the saddle is rotated relative to the locking cap, the first side is attached to the locking cap and in a second assembled position, the first side is not attached to the locking cap. - View Dependent Claims (10, 11, 12, 13)

14. A rod coupler system comprising:
-
a coupling body having a bone fastener disposed therethrough, a locking cap adapted for attachment to said coupling body, and a saddle having a first side of said saddle abutting said locking cap, and a second side of said saddle opposite said first side, said second side having a concave portion having a radius and including at least one dimple within the radius, the concave portion abutting an elongate rod along at least two lines of contact between said saddle and said elongate rod. - View Dependent Claims (15, 16, 17, 18, 19, 20)
