Claims Analysis
Total Claims: 35
Claim 1
Independent Claim
134 words
1 . A vascular device for removing material from body lumens, the device comprising: a catheter body having a proximal end and a distal end; a cutter assembly located at the distal end of the catheter body, the cutter assembly comprising a housing having at least one opening and a cutter having at least one cutting surface configured to rotate relative to the housing, where movement between the housing opening and the cutting surface removes material located therebetween; a rotating shaft extending through the catheter body and coupled to the cutter, the shaft having a proximal end adapted to couple to a first rotating mechanism; and a deflecting member extending along the catheter body, such that movement of the deflecting member causes deflection of the cutter assembly relative to an axis of the catheter.
