Needles, Aspiration/Injection, Brain
Definition : Needles designed for injection and/or aspiration inside the brain tissue. These devices typically consist of thin needles with insertion lengths of 15 cm (6 inches) or more and blunt tips to minimize the risk of brain tissue damage. Brain tissue injection/aspiration needles are mostly used during neurosurgery for drainage of hematomas and cyst aspirations as well as for abscess drainages; they may also be used in aspiration biopsies and as guides in some minimally invasive therapies.
