Abstract
A method of treating a lesion in a body lumen to enlarge a passageway in the lumen including inserting a cutting member and tracking member through a first lumen of a catheter, withdrawing the catheter from the cutting member and tracking member, inserting the catheter over the tracking member and leaving the cutting member outside the catheter, and expanding a portion of the catheter to move the cutting member into cutting contact with the lesion. A device for treating a lesion in a body lumen including a cutting member and tracking member is also provided.
Claims20
A method of treating a lesion in a body lumen in a patient's body, the method comprising:
- a) inserting a cutting member and tracking member through a first lumen of a first catheter;
- b) withdrawing the first catheter from the cutting member and tracking member and removing the first catheter from the body lumen;
- c) after step (b) inserting either the first catheter or a second different catheter over the tracking member and the cutting member remaining outside the catheter during insertion of the catheter;
- and
- d) after step (c) expanding a portion of the catheter inserted over the tracking member in step (c) to move the cutting member radially into cutting contact with the lesion to thereby enlarge a passageway in the body lumen.
A method of treating a lesion in a body lumen in a patient's body, the method comprising:
- inserting a cutting member and tracking member into the body lumen, the tracking member extending outside the body lumen;
- inserting a catheter over an exposed proximal end of the tracking member so the tracking member extends through a first lumen of the catheter and the cutting member is adjacent the catheter and does not extend through the first lumen;
- and
- moving the cutting member radially away from the tracking member into cutting contact with the lesion to enlarge a passageway in the body lumen.
