Abstract:
1. A device for removing tissue from a patient, the device comprising: an elongate body that is flexible over at least a portion of its length, the elongate body having a proximal end, a distal end, and a longitudinal axis therebetween, the elongate body having opposed first and second major surfaces with a lateral orientation across the axis, the elongate body further comprising a rigid shaft, a flexible portion extending from one end of the shaft, a guidewire coupler on or in the flexible portion, and a first handle coupled with an end of the shaft opposite the flexible portion; and a plurality of blades on the first major surface, each blade having a first end adjacent the first major surface and extending to a cantilevered second end, a first edge between the first and second ends of the blade being oriented toward the distal end of the elongate body, a second edge between the first and second ends of the blade being oriented toward the proximal end of the elongate body, a height of the blade between its first and second ends, and an axial length of the blade between its first and second edges, wherein at least one of the first edge or the second edge comprises a cutting edge so as to cut the tissue when the first major surface is urged toward the tissue and the elongate body advances along a path toward one end of the elongate body, wherein both the height and the axial length of each blade are greater than a transverse width of the blade, and wherein the guidewire coupler is configured for attachment to the guidewire from the distal direction of the distal end, and wherein the guidewire extends distal of the distal end when the guidewire is coupled to the guidewire coupler.
