Patent attributes
In accordance with an embodiment of the present invention, a system for widening passages in the body of a patient includes a member extendable into a patient with a proximal end and a distal end with a tip and a hollow interior extending therebetween; bristles adjacent the distal end of the member such that rotation of the proximal end of the member causes rotation of the bristles to remove material from walls of pre-existing passages in the patient and, all of the bristles are inclined away from the tip of the distal end as they extend out from the distal end; a guide wire having a proximal end and a distal end disposed within the hollow interior and extendable into the patient; and a non-rotating capture member coaxially aligned with and fixed near the guide wire distal end to be disposed within the hollow interior and extendable into the patient.
