Just, being production manner of the production mannered null medical application lead line

摘要

A method of manufacturing a medical electrical lead includes molding a lead body preform, stringing an electrode onto the preform and over molding the preform with a polymer to form a lead body portion. The preform has a proximal end, a distal end and at least one lumen extending between the proximal and distal ends. At least one asymmetric region of the preform has a transverse cross-section that has a non-circular outer dimension. The over molding causes the asymmetric region to become substantially circular.
