Filed:

Dec 28, 2006

Appl. No.:

11/648408

Inventors:

Robert Ohline - Redwood City CA, US
Katherine Whitin - Woodside CA, US
Amir Belson - Sunnyvale CA, US
Christopher Justice - Prairie Village KS, US

International Classification:

A61B 5/05
A61B 1/00

US Classification:

600117000, 600424000

Abstract:

One RFID equipped instrument includes an elongate body with a plurality of uniquely identified radio frequency identification chips spaced along the length of the elongate body. One system used for determining the position of an instrument includes an instrument; a plurality of radio frequency identification chips attached to the instrument; a reader connected to an antenna and adapted to communicate with each radio frequency identification chip using the antenna. One method for determining the position of an instrument using radio frequency identification chips includes providing a radio frequency identification chip reader and antenna; providing an instrument having a longitudinal axis and comprising a plurality of radio frequency identification chips placed along the longitudinal axis; moving the instrument relative to the antenna; and using information about a radio frequency identification chip detected by the antenna to determine the position of the instrument.

Abstract:

A system for determining a position of an endoscopic instrument comprises an endoscopic instrument having an elongate body portion, the elongate body portion being configured to be moved along a path, and a plurality of sensible elements disposed at differing axial positions along the elongate body portion, wherein each sensible element transmits unique information indicative of the respective differing axial position of the sensible elements. The system further comprises a sensing device positioned to receive the unique information from a respective sensible element when the respective sensible element is in sufficient proximity to the sensing device, the sensible elements being in sufficient proximity to the sensing device at differing times based upon a position of the elongate body portion relative to the path.
