Cerebrum's cerebral material sampling device for biopsy, has electrode coupled to stimulator to send electrical stimulation in cerebrum to locate functional and non-functional areas of cerebrum in exploratory phase before sampling phase

摘要

The device (10) has a catheter (20) penetrating a cerebral material, and a trocar introduced into the catheter to carry out a sampling process, where the device is made up of a synthetic material. A distal end of the catheter and the trocar comprises a sampling window (21) that is overlapped in a sampling phase. An electrode (60) is coupled to a stimulator by a connection cable (63) to send electrical stimulation in a cerebrum to locate functional and non-functional areas of the cerebrum in an exploratory phase before the sampling phase. The electrode is introduced in the catheter.
