Abstract
A catheter has a proximal end and a distal end and comprises an outer tube having a proximal end, an inner sheath slidingly received within the outer tube and extending distally from the outer tube, and a rotatable shaft extending from the proximal end of the outer tube to within the inner sheath. The rotatable shaft is axially fixed with respect to the outer tube and axially moveable within and with respect to the inner sheath. The rotatable shaft includes a proximal substantially rigid section and a distal flexible section. The catheter further includes a working element carried on the distal flexible section of the rotatable shaft.
