Abstract

An endobronchial probe includes a deflector having a bore extending therethrough at an angle to its long axis for passage of a tool. The probe includes a location sensor and an ultrasound imager. A push-pull anchoring system comprises a plurality of guides and wires that can extend beyond the guides and retract within the guides. When extended the wires diverge from the long axis sufficiently to engage a bronchus. The probe includes a balloon disposed on the distal segment contralateral to bore that when inflated urges the mouth of the bore into contact with the bronchial wall.
