Abstract
An apparatus and method facilitating removal, from a body, of an implanted elongated structure with a lumen such as a lead or catheter, comprises a plurality of wire stylets that are inserted together into the lumen and subsequently moved relative to each other in a longitudinal direction by manipulation at the proximal end. The stylets have dimensional features on their adjacent sides that mate together to minimize the overall diameter of the stylet assembly during insertion into the lumen. Interaction of the features on the stylets' adjacent sides, resulting from the subsequent relative displacement, causes the assembly to expand radially. The expansion is sufficient to engage the luminal surface of the implanted structure, thereby allowing traction forces to be applied, while minimizing deformation of the implanted structure. If repositioning of the apparatus is necessary, the stylets may be returned to initial relative positions, reestablishing a minimal overall diameter.
