Pajunk BrainPro needles have been specially designed for single or repeated extraction of tumorous cerebral tissue, using a stereotaxic frame. They are easy to handle and highly functional: The needle tip has a lateral opening for the incorporation of large biopsy material samples. The tissue cylinder is large enough for the recovery of histology samples. The sealed, closed system also ensures a good vacuum and excellent biopsy material quality. BrainPro biopsy sets are designed as an entirely disposable set of instruments, guaranteeing total hygiene and therefore also protection against prion transfer.
