Abstract
An apparatus formed of a flexible coil concentrically disposed around a flexible wire includes one or more radially expansible, helically configured wire loops. The loops grip deposits within a vessel and allow the deposits to be sheared from the interior wall of the vessel when the apparatus is withdrawn from within the vessel.
