         15 . The device of  claim 1 , wherein the device is mounted on or integrated into a distal end of a catheter. 
     
     
         16 . The device of  claim 1 , wherein the surgical procedure includes a neurosurgical procedure and wherein the distal face of the solid optical window is configured to come into contact with brain tissue. 
     
     
         17 . The device of  claim 16 , wherein the device is mounted on or integrated into a distal end of a neuroendoscope. 
     
     
         18 . The device of  claim 16 , wherein the device is mounted on or integrated into a lateral surface of a neuroendoscope. 
     
     
         19 . The device of  claim 1 , further comprising a flushing channel formed through the solid optical window from the proximal face to the distal face of the solid optical window.
