1. A method of detecting and tracking a current position of a tissue or bone anchor, comprising:
- sensing, via a receiver associated with the tissue or bone anchor, reference signals generated by a surgical navigation system;
conveying, via a transmitter associated with the receiver, positional signals as a function of a current location of (i) the receiver and (ii) the reference signals generated by the surgical navigation system;
wherein the receiver is configured so that the positional signals correspond to the current position of the tissue or bone anchor.

Abstract
An integrated surgical anchor/localization sensor is disclosed. The anchor is adapted to be secured to an anatomical structure and contains a sensor housing. A receiver is located within the sensor housing and is adapted to sense reference signals generated by a surgical guidance system. A transmitter, connected to the receiver, conveys to a processor signals received by the receiver, so that the signals transmitted by the receiver are indicative of a current position of the anchor. Various other structures and methods are also disclosed.

8. A system for attaching a surgical anchor/localization sensor to a bone in a patient for use during a medical procedure, said system comprising:
-
a bone anchor operable to be substantially rigidly secured to the bone of the patient; a localization sensor to identify a current position of said bone anchor; a connector securing and retaining said localization sensor to said bone anchor to form an integrated bone anchor/localization sensor; and a device engage and drive at least a portion of said integrated bone anchor/localization sensor into the bone of the patient. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
