Clot evacuation and visualization devices and methods of use

Abstract

An integrated clot evacuation device having visualization for use in neurosurgical applications, particularly for the evacuation of clots formed as a result of intracranial hemorrhage (ICH). The device may further include an integrated camera and light for visualizing the interior of the brain and the clot itself. Further, the device is configured to evacuate clots through aspiration and irrigation.

1 . An evacuation device comprising:
 an elongate body having a proximal end and a distal end, wherein the elongate body comprises one or more lumens, wherein the one or more lumens comprises an evacuation lumen extending along at least part of the length of the elongate body, and wherein the elongate body comprises a distal opening in fluid communication with the evacuation lumen at or near the distal end of the elongate body;   a visualization element located at or near the distal end of the elongate body for transmitting images received from inside of a patient; and   an obturator configured to be removably inserted in the evacuation lumen and close off the distal opening.   
     
     
         2 . The evacuation device of  claim 1 , wherein when the obturator is removably inserted in the evacuation lumen and closes off the distal opening, the evacuation device forms an atraumatic tip.
