Abstract
An introducer that includes a tubular outer sheath having proximal and distal ends, a tubular inner sheath having proximal and distal ends, rotatably mounted within the outer sheath, and a knob, positioned at the proximal end of the inner sheath, so that the inner sheath is rotatable through the knob. A gripping mechanism is coupled to the distal end of the inner sheath and rotatable with the inner sheath to compressively engage a distal portion of a lead or catheter extending through the inner sheath in response to the rotation of the inner sheath through the knob.
