Abstract
The present invention provides minimally invasive devices and methods for delivering a spinal connector to one or more spinal anchor sites in a patient's spinal column. In one embodiment, a spinal implant and access device is provided that includes a U-shaped receiver member, a bone-engaging member, and an extension member. The U-shaped receiver member can have a recess formed therein that is adapted to seat a spinal connector. The bone-engaging member can extend distally from the receiver member and it can be adapted to engage bone to thereby mate the receiver member to bone. The extension member can extend proximally from the receiver member and it can include a frangible portion formed thereon that is adapted to break when a predetermined force is applied thereto thereby allowing at least a portion of the extension member to be separated from the receiver member.
