Abstract: Telescoping catheters for selectively moving a component of a medical device system are disclosed. An illustrative telescoping catheter may comprise a proximal hub adjacent a proximal end of the catheter, a drive cable, and a telescoping section extending from a proximal end adjacent the proximal hub to a distal end. The telescoping section may comprise an intermediate sheath having a proximal end coupled to the proximal hub and extending distally to a distal end, an outer sheath disposed over the intermediate sheath, the outer sheath having a proximal end and a distal end, an inner sheath disposed within the intermediate sheath, the inner sheath having a proximal end and a distal end, and a seal member disposed between the intermediate sheath and an outer surface of the inner sheath. The intermediate sheath may be configured to be longitudinally displaced relative to the inner and outer sheaths.
