摘要：
An apparatus is disclosed for removing tissue from a patient's body. The apparatus comprises an elongate member defining a lumen and a tissue removal member disposed within the lumen. The tissue removal member comprises a flexible shaft formed from a plurality of strands, and a coil that is helically disposed around the shaft. The coil is substantially in contact with the shaft along a length of the shaft. The coil forms a plurality of outwardly extending projections and each pair of the plurality of outwardly extending projections defines a spacing therebetween. Upon rotation of the tissue removal member within the elongate member, material is conveyed through the lumen of the elongate member. A related method of manufacturing a tissue removal member is also disclosed.
