The comments from Mauna Kea in the full year 2016 result give some idea of current sales volumes in the industry:
"The Company shipped 54 Cellvizio systems in the full year 2016, including 6 systems placed under the Company’s recently launched consignment program, compared to 51 systems in the full year 2015. The Company shipped 43 clinical systems and 11 pre-clinical systems in the full year 2016, compared to 38 clinical systems and 13 pre-clinical systems in the full year 2015. Consumable probes unit volume increased 7% to 716 units, compared to 669 probes in the full year 2015. The number of probe reorders (probes sold to existing customers) increased from 492 in the full year 2015 to 541 in the full year 2016, representing 10% growth year-over-year. Consumable probe reorder sales grew 34% for the full year 2016. The year-over-year increases in consumable probe sales, and particularly the reorder rate and sales, reflect increased utilization of the Cellvizio systems, particularly in the U.S., along with growth of the installed base."
