초록

The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and method relate to removal of the occluding material from the blood vessels as well as other body lumens.

대표청구항 ▼

We claim: 1. A method for cutting and removing occlusive material from a body lumen, the method comprising:providing a vascular device comprisinga catheter body sized and configured for axial advancement in the body lumen, the catheter body having a center axis along which axial advancement occurs and including spaced apart proximal and distal ends,a cutter assembly having an outside diameter attached at the distal end of the catheter body, the cutter assembly comprising a housing having at least one opening and a cutter having at least one helical cutting surface configured to rotate about the center axis relative to the housing to cut occlusive material at the distal end of the catheter body and convey the occlusive material from the body lumen proximally into the housing,a drive mechanism at the proximal end of the catheter body;a torque shaft coupled to the drive mechanism and extending through the catheter body and coupled to the cutter to rotate the helical cutting blade about the center axis relative to the housing,a conveyor mechanism helically wound about the torque shaft in a direction common with the helical cutting blade to convey the occlusive material conveyed into the housing by the helical cutting blade further proximally along the catheter body for discharge without supplement of a vacuum pump, anda deflecting mechanism slidable within the catheter body in response to a force applied at the proximal end of the catheter body for deflecting the cutter assembly relative to the center axis of the catheter body to point the cutter assembly toward a side of the body lumen without necessitating axial advancement of the catheter body in the body lumen,manipulating the proximal end of the catheter body to insert the distal end of the catheter body within the body lumen,manipulating the proximal end of the catheter body to advance the distal end of the catheter body within the body lumen toward the occlusive material,operating the drive mechanism to rotate the helical cutting surface about the central axis to cut occlusive material at the distal end of the catheter body, to convey the occlusive material from the body lumen proximally into the housing, and to convey the occlusive material conveyed into the housing by the helical cutting surface further proximally along the catheter body by the conveyor mechanism for discharge without supplement of a vacuum pump,operating the deflecting mechanism at the proximal end of the catheter body to deflect the cutter assembly relative to the center axis of the catheter body to point the cutter assembly toward a side of the body lumen without necessitating axial advancement of the catheter body in the body lumen, androtating the distal end of the catheter body when the cutter assembly is deflected to sweep the cutter assembly in an arc about the center axis to cut occlusive material in a region larger than the outside diameter of the cutter assembly, wherein rotating the distal end of the catheter body comprises operating a torque control device separate from the deflecting mechanism to manually or automatically control the sweep of the cutter assembly.
