Abstract: An apparatus is disclosed for conveying material, for example for removal of tissue from a body. The apparatus generally comprises an elongate member defining a lumen and having an aperture at its distal end and a tissue removal member disposed within the lumen. The apparatus may further include a motorized source of rotational energy operatively connected to the tissue removal member. The tissue removal member may comprise a shaft having at least one outwardly extending projection, and the tissue removal member, or a projection thereof, may be recessed proximally relative to the aperture in order to prevent unnecessary damage to the surrounding environment. The elongate member may define at least one slot extending proximally from said distal end of said elongate member. The apparatus disclosed herein may be useful for, for example, removal of tissue from a patient's body in a minimally invasive manner.

Abstract: 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.

Abstract: An apparatus is disclosed for removing tissue from a patient's body. The apparatus comprises a first elongate member defining a lumen and having an open distal end. The open distal end defines an opening and comprises a tip, where the tip is structured to reduce damage to tissue within the patient's body. The apparatus further comprises a tissue removal member disposed within the lumen of the elongate member. The tissue removal member comprises a distal end that is recessed from the tip of the elongate member. At least a portion of the tissue removal member protrudes beyond the opening to allow access to tissue distal to the opening. Related hollow members with blunt tips are also disclosed.
