Abstract
An introducer set including a sheath and dilator is formed within a heated mold to form a smooth external shape on the set. The distal end of the sheath is embedded in the dilator and also formed at an angle oblique to the longitudinal axis of the introducer set. This construction permits the sheath to be inserted into the body with a minimum of trauma to the patient and also permits easy removal of the sheath from the dilator.
