Abstract:
A brake device for engaging an inner surface of a drill string within a borehole. The brake device has a driving member that defines a plurality of wedge surfaces, a brake retainer that receives at least a portion of the driving member, and a plurality of braking elements positioned in contact with at least a portion of the outer surface of the driving member. The brake retainer has a biasing member that is operatively coupled to the driving member. The biasing member of the brake retainer biases the driving member in a proximal direction relative to the longitudinal axis of the drill string to position the wedge surfaces in contact with corresponding braking elements, and the wedge surfaces drive the braking elements radially outwardly to engage the inner surface of the drill string. The brake device is not coupled to an inner tube assembly.

Claim (Index 8):
The brake device of  claim 6 , wherein the at least one characteristic of the drill string comprises a direction of the borehole, a dip angle of the borehole, pressure within the drill string, a pressure change within the drill string, gravitational field strength, an angular measurement (azimuth) relative to a reference point within the drill string, or combinations thereof.
