Claim 1
Independent Claim
241 words
An apparatus for atherectomy, the apparatus comprising: a catheter; a hollow wire guided by said catheter, said hollow wire including at least one rotary member for removing at least one of deposits, coatings and occlusions in a vessel; a first helically wound hollow wire attachment provided on a proximal end of said at least one rotary member, and a second helically wound hollow attachment provided on a distal end of said at least one rotary member; a taut wire extending through said first and second helically wound attachments and said rotary member; means provided on a proximal end of said taut wire and cooperable with a proximal end of said first helically wound hollow wire attachment for enabling a radial expansion of said at least one rotary member from a paraxial position upon drawing the taut wire in a distal direction of the apparatus; a drive for the apparatus including means for receiving said catheter, and rotary connecting means for connecting a rotary drive for the at least one rotary member, wherein the rotary connecting means is axially reciprocatable relative to the catheter by a motor; and a sleeve firmly and rotatably connected to the rotary connecting means and in a non-rotary manner to a drive casing, said sleeve having a closed meandering groove guided around a circumference engageable with a cam of a transmission part rotating at a lower angular velocity than an angular velocity of the rotary connecting means.
