Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 198 words
1 . A vascular device for removing material from body lumens, the device comprising: a steering member; a catheter body having a stiffer proximal portion and a more flexible distal portion: a steering member located along the catheter body, the steering member having a curved section located towards the distal end. where the curved section is more flexible than the stiffer proximal portion of the catheter body such that when located along the flexible portion the flexible distal portion of the catheter body takes tile shape of the curved section: 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 tile housing opening and the cutting surface removes material located therebetween; a rotating shaft extending through tile catheter body and coupled to the cutter, the torque shaft having a proximal end adapted to couple to a first rotating mechanism; and where on advancement of the curved section of the steering member out of the distal portion of the sheath, the curved section reshapes the catheter body.
Claim 2
Dependent Claim 198 words
1 . A vascular device for removing material from body lumens, the device comprising: a steering member; a catheter body having a stiffer proximal portion and a more flexible distal portion: a steering member located along the catheter body, the steering member having a curved section located towards the distal end. where the curved section is more flexible than the stiffer proximal portion of the catheter body such that when located along the flexible portion the flexible distal portion of the catheter body takes tile shape of the curved section: 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 tile housing opening and the cutting surface removes material located therebetween; a rotating shaft extending through tile catheter body and coupled to the cutter, the torque shaft having a proximal end adapted to couple to a first rotating mechanism; and where on advancement of the curved section of the steering member out of the distal portion of the sheath, the curved section reshapes the catheter body.
Claim 3
Dependent Claim 53 words
2 . The device of claim 1 , where the deflecting member comprises a mandrel slidably located in the catheter body and extendable out of a distal opening of the catheter body, where upon extending out of the distal opening to push against tissue to deflect the distal end of the catheter body.
Claim 4
Dependent Claim 52 words
3 . The device of claim 1 , where a portion of the housing comprises a curved surface and the opening forms a plane across the curved surface such that as the cutting surface rotates across the opening a portion of the cutting surface extends out of the housing through the opening.
Claim 5
Dependent Claim 25 words
4 . The device of claim 1 , where the torque shaft and cutter each have a lumen allowing for advancement of a guidewire therethrough.
Claim 6
Dependent Claim 24 words
5 . The device of claim 1 , cutter comprises a plurality of flutes and the cutting surface is an edge of the flute.
Claim 7
Dependent Claim 16 words
6 . The device of claim 5 , where the edge or the flute is helical.
Claim 8
Dependent Claim 38 words
7 . The device of claim 5 , where each flute is arranged relative to the openings in the housing such that during a total length of the cutting surface exposed in the housing opening remains the same.
Claim 9
Dependent Claim 24 words
8 . The device of claim 1 , further including a ferrule linking tile housing to the said outer tube oil the catheter body.
Claim 10
Dependent Claim 38 words
9 . The device of claim 1 , where the shaft has at least one helical conveyor member wound about an exterior such that rotation of the torque shaft conveys material across a length of the torque shaft.
Claim 11
Dependent Claim 27 words
10 . The device of claim 1 , where the helical conveyor member is wound in the same rotational sense as tile helical lutes on the cutter,
Claim 12
Dependent Claim 18 words
11 . The device of claim 1 , where a guide-wire portion is fixedly attached to the cutter.
Claim 13
Dependent Claim 23 words
12 . The device of claim 1 , where the deflecting member comprises a wire extending along a length of the flexible catheter.
Claim 14
Dependent Claim 21 words
13 . The device of claim 1 , further comprising a burr rotatably located on a tip of the cutter assembly.
Claim 15
Dependent Claim 106 words
14 . A vascular device for removing material from body lumens, tile device comprising: a catheter body having a proximal portion and a distal portion: a steering tube having varying stiffness along its circumference at the distal portion; 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 tile housing, where movement between the housing opening and the cutting surface removes material located there between and the distal portion of the steering tube is attached to the cutter assembly.
Claim 16
Dependent Claim 106 words
14 . A vascular device for removing material from body lumens, tile device comprising: a catheter body having a proximal portion and a distal portion: a steering tube having varying stiffness along its circumference at the distal portion; 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 tile housing, where movement between the housing opening and the cutting surface removes material located there between and the distal portion of the steering tube is attached to the cutter assembly.
Claim 17
Dependent Claim 21 words
15 . A device of claim 14 , where tension on the steering tithe deflects the distal portion of tile catheter.
Claim 18
Dependent Claim 21 words
16 . A device of claim 14 , where compression of the steering tube deflects the distal portion of tile catheter.
