Patent ID: 7731731

Claim:
A system for widening passages in the body of a patient comprising: a member extendable into a pre-existing passage of the patient, said member having a proximal end and a distal end with a hollow interior extending therebetween; moveable bristles disposed on the member adjacent the distal end such that rotation of the proximal end of the member causes rotation which, in turn, rotates the bristles, the bristles being operable upon rotation to remove material from walls of the pre-existing passage within which the bristles rotate and, said bristles being inclined away from the distal end of the member; a guide wire having a proximal end and a distal end being movably disposed within the hollow interior of the member and extendable into the patient and at least one channel running longitudinally along a portion of the guide wire; a non-rotating capture member coaxially aligned with, fixed to and near the distal end of the guide wire and adapted to be disposed within the hollow interior of the member and extendable into the patient beyond the distal end of the member by the guide wire, the capture member comprising non-rotating bristles that are circumferentially aligned around and fixed to an annular ring positioned around and coaxially aligned with the guide wire and having at least one tab on an inner edge of the annular ring where the at least one tab slidingly engages the at least one channel in the guide wire and the non-rotating bristles are to capture the material removed from the walls of the pre-existing passage in the patient; and a cap with an open-ended conical shape that is open toward the proximal end of the guide wire and that is coaxially aligned with and attached to the guide wire distal of the non-rotating bristles and the at least one channel.
