Abstract

A system to detect objects tagged with transponders used in-vivo or proximate a surgical site. The system includes a wand housing, at least one antenna carried by the wand housing, a fuse coupled to the at least one antenna and selectively operable to permanently disable the at least one antenna, and a disable circuit configured to selectively blow the fuse to permanently disable the at least one antenna responsive to a lapse of a defined amount of usage. A pouch holds a transponder and is physically coupleable to objects such as surgical sponges or gauze.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 60 / 811,376, filed June 6, 2006, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention generally relates to detecting the presence or absence of an object tagged with a transponder, for example, detecting a surgical object during a surgical procedure.
