摘要:
A method of treating a vessel in a subject comprises the steps of advancing a device distally across a treatment zone in a vessel, wherein the device comprises an elongated catheter having a lumen and a distal end, and a radially expansive treatment element disposed in the lumen and configured for axial movement relative to the catheter; deploying the radially expansive treatment element proud of the distal end of the catheter to radially expand and circumferentially impress against the vessel lumen at a distal end of the treatment zone; and withdrawing the deployed radially expansive treatment element proximally along the treatment zone with the treatment element circumferentially impressed against the vessel lumen to mechanically and circumferentially denude the treatment zone of the vessel. The radially expansive treatment element is then recaptured into the lumen of the catheter, before the device is withdrawn from the treated vessel.
