Abstract
A probe or catheter, usable with a navigation system, includes a longitudinal lumen that curves outwardly through a sidewall prior to reaching a distal tip of the probe. The distal tip contains a position sensor as part of the navigation system. The lumen provides a working channel that guides a tool into a sidewall of a branched structure without requiring the distal end of the probe to be facing the branched structure.
Claims21
A probe for accessing tissue in a branched structure comprising:
- a catheter having a lumen and a distal end, said central lumen extending longitudinally through said catheter and curving laterally through a sidewall of said catheter to form a lateral port proximal of said distal end;
- a sensor located in said distal end of said catheter, distal of said lateral port, operatively associated with a navigation system to provide location information thereto such that positions of said distal end may be displayed and recorded.
A method of treating lung tissue comprising:
- navigating a probe to a target site such that a distal end of said probe is just distal of said target site;
- extending a tool through a sidewall of said probe to said target site;
- treating said tissue using said tool.
A probe for use with an electromagnetic probe navigation system comprising:
- a catheter having a longitudinal lumen that terminates through a sidewall thereof prior to reaching a distal end of said catheter;
- a position sensor in said distal end of said catheter capable of communicating position information to said electromagnetic probe navigation system;
- a tool extendable through said longitudinal lumen and beyond said sidewall.
