Abstract
An abrasion resistant implantable lead is described including a protector for preventing abrasion to lead insulation. A helix-shaped protector can be placed around portions of the implantable lead to prevent frictional contact between the lead and the metallic casing of an implantable medical device, known as a pulse generator. The protector can have a cross-section and end-view of various shapes. The protector can be made of a flexible, elastomeric biocompatible material and can be coated by a hydrophilic surface to minimize the coefficient of friction between the protector and the casing of the pulse generator. The protector can have an inner cross-sectional diameter equal to or less than an outer cross-sectional diameter of the lead insulation, ensuring a snug fit. A toolkit for selecting, sizing and positioning the proper protector is described.
