摘要:
A device (1, 30, 40, 50, 60) for denuding a vein comprises a vein denuding head (3) operatively attached to an elongated catheter member (2) and configured for transluminal delivery and deployment in the vein. The vein denuding head comprises a helical coil (4) that is self-adjustable from an uncoiled delivery configuration suitable for transluminal delivery within the catheter member and a coiled deployed configuration having a diameter greater than the vein to be denuded that circumferentially engages an internal lumen of the vein when deployed. The helical coil has an abrasive surface configured to circumferentially denude the internal lumen of the vein when the coil is moved axially along the body lumen in the coiled configuration. The helical coil may be a single helical coil element.
