1. A tissue separator assembly comprising:

  • a proximal end assembly;

    a catheter assembly, extending from the proximal end assembly, comprising;

    a shaft having a distal portion and defining an axis at the distal portion; and

    an elongate tissue separator element having a proximal part and a distal part, the distal part connected to the distal portion of the shaft and movable between a retracted state, adjacent to the distal portion, and an outwardly extending, operational state; and

    the proximal end assembly comprising a first driver, operably coupled to the tissue separator element, constructed to (1) move the tissue separator element from the retracted state to the operational state, and (2) automatically rotate the tissue separator element about the axis, whereby a tissue section is separable from surrounding tissue by the moving tissue separator element.
