摘要 |
Disclosed is a tissue removal device. The device includes an outer tubular body, an inner tubular body and a cutting edge on the inner tubular body. The outer tubular body includes a window, which may be opened or closed by moving the cutting edge. The cutting edge has a hardness that exceeds the hardness of the material of the inner tube. The cutting edge may have a Rockwell C hardness of at least about 50, while the inner tube has a Rockwell C hardness of no more than about 40. The cutting edge may be formed by a milling step, and the inner tube may be formed by a drawing step. Tissue severed by the cutting edge may be removed at a rate of at least about 1.8 grams per minute through the inner tube, and the outer tubular body may have an outside diameter of no more than about 3.5 mm. |
