1. An integrated surgical anchor/localization sensor, comprising:
- an anchor adapted to be secured to an anatomical structure;
a receiver, for sensing signals generated by a surgical guidance system, wherein the receiver includes a plurality of collinear electromagnetic coils wound at differing angles;
a transmitter coupled to the receiver, for conveying to a processor signals received by the receiver; and
a connector for securing at least the receiver to the anchor, the connector being configured so that the signals conveyed by the transmitter are indicative of a current position of the 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.
