Intended Use

The Brain Biopsy Needles are used during guided procedures and methods deemed safe by the physician/surgeon to remove a targeted tissue sample for biopsy.

Device Story

Side-cutting brain biopsy needle; consists of two nested cannulae with distal sampling windows. Physician inserts needle to target depth; optional aspiration syringe attached to support tissue collection. Inner cannula rotated to excise tissue sample; inner cannula removed to retrieve sample. Procedure allows multiple biopsies via same trajectory. Used in clinical settings for brain tissue sampling. Device variation (MDBN-08-28) validated as MRI conditional to allow visualization during guided procedures. Benefits include minimally invasive tissue acquisition for diagnostic analysis.

Clinical Evidence

Bench testing only. MRI modeling and MRI testing performed to confirm MRI compatibility of the MDBN-08-28 variation.

Technological Characteristics

Side-cutting biopsy needle; two-cannula design; single-patient use; sterile. MRI conditional variation (8 mm sample window, 28 cm length).

Indications for Use

Indicated for use in patients undergoing guided procedures to remove targeted brain tissue samples for biopsy, as determined by a physician or surgeon.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

#### 5.1 Product Description

Brain Biopsy Needles are used to remove a targeted sample of brain tissue for analysis. These Brain Biopsy Needles are side-cutting needles. Side-cutting needles can extract several tissue samples without requiring a new trajectory.

Biopsy needles are used to sample brain tissue or to extract brain tissue samples to determine tissue abnormality or any deviation from healthy brain tissue. These Brain Biopsy Needles substantially consist of two cannulae that fit inside one another. Both cannulas have a sampling window opening in the distal tip. The inner cannula window opening has a sharp edge. The Brain Biopsy Needle is placed into tissue to the desired depth. An aspiration syringe may be attached to the brain biopsy to support aspiration of a small amount of tissue into the sampling window. The inner cannula is rotated such that the sampling window removes a tissue sample. The inner cannula is removed. The tissue sample from the inner cannula is removed for analysis. The inner cannula may be passed back through the outer cannula and additional biopsies can be taken as directed by the surgeon.
