Abstract
An implantable elastomeric article having modified surface characteristics on at least one surface obtained by application of an acid on said at least one surface and after a predetermined treatment time removing the acid by rinsing. The treatment gives the surface an increased roughness that decreases the friction against another object. A method of modifying surface characteristics of at least one surface on an implantable elastomeric article, comprising application of an acid, followed by rinsing. A method of assembly of an implantable electrode lead made of silicone tubing and a spiral conductor, comprising treating the tubing with an acid before inserting the conductor into the tubing.
