  • Ultrasonic-fiberoptic imaging ventricular catheter
    Patent number: 5690117
    Abstract: A rigid ultrasonic-fiberoptic stylet situated within a modified intracranial silastic catheter allows indirect and direct real time visualization through the tip of the catheter, The stylet is provided with fiberoptics and an ultrasound transducer which allows viewing through the end of the catheter. The ultrasonic portion of the stylet allows the surgeon to correctly aim the stylet and catheter towards the ventricle by giving the surgeon a 2-dimensional echogram view of the ventricle and allows the surgeon to maintain the proper trajectory or path towards the anterior horn of the lateral ventricle as the stylet and catheter are passed through the brain. The fiberoptic portion of the stylet allows the surgeon to directly view the interior of the anterior horn of lateral ventricle once the ventricle is punctured.
