Surgical access assembly and method of using same
11464539 · 2022-10-11 · ·

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

A cerebral catheter device for draining fluid from the brain of a patient is described. The device may be used as part of a ventricular shunt system. The device includes an elongate tube for insertion into the brain of a patient to a vicinity of a desired target. A head is attached to the elongate tube that has a passageway in fluid communication with a lumen of the elongate tube. Formations are provided on the external surface of the head for securing the head in a hole formed in the skull of a patient. The head further includes a first fluid connector portion that is attachable to an associated drainage catheter device. This allows fluid communication to be established between the lumen of the elongate tube and a drainage catheter device via the passageway of the head.
