disclosed is a spinal transconnector device for coupling longitudinal spinal rods on either side of the mid - sagittal plane . the device includes two interconnected rod engagement elements , a first rod engagement elements having a vaulted surface adapted to secure to a first longitudinal spinal rod via an interference fit comprising compression of the first longitudinal spinal rod against the generally vaulted surface ; and an interference pin that advances into a bore of the first rod engagement element forming an interference fit between the interference pin and the rod engagement element . the interference fit can be associated with elastic deformation of the first rod engagement element occurring as a consequence of the interference pin being advanced through the bore in the engagement element and contacting a surface of the first longitudinal spinal rod .
