1. A probe, comprising:

  • an elongated shaft having a distal end and an internal lumen;

    a shaft support at least partially disposed in the internal lumen, the shaft support comprising a cylindrical member and a plurality of shafts that extend from the cylindrical member; and

    a microelectrode array film comprising;

    a first portion disposed on the cylindrical member of the shaft support;

    a second portion disposed on the distal end of the elongated shaft;

    a first isolating layer defining a plurality of microelectrode film shafts extending from the cylindrical member of the shaft support;

    a metal layer disposed on the first isolating layer and defining a plurality of microelectrode elements and a plurality of traces extending from a corresponding microelectrode element of the plurality of microelectrode elements to the cylindrical member of the shaft support;

    a second isolating layer at least partially disposed on the metal layer;

    a helical ribbon cable coupled with the first portion and the second portion of the microelectrode array film to permit movement of the plurality of microelectrode film shafts, the helical ribbon cable separating the first portion and the second portion; and

    each microelectrode film shaft of the plurality of microelectrode film shafts disposed on an outside face of a respective shaft of the plurality of shafts that extend from the cylindrical member of the shaft support, each microelectrode film shaft comprising a respective microelectrode element of the plurality of microelectrode elements on the outside face of the respective shaft and a respective trace of the plurality of traces extending from the respective microelectrode element.
