Lumbar Puncture

Myelo-Nate® Spinal Fluid Sampling

Myelo-Nate® neonatal/pediatric lumbar puncture needles and kits provide access to the spinal column for the purpose of obtaining a cerebrospinal fluid (CSF) sample for diagnostic analysis. The short bevel design with Quincke type needle minimizes trauma and infiltration by spreading and displacing rather than cutting through the dura mater.


The Myelo-Nate® Lumbar Puncture Needle provides access to the spinal column for the purpose of obtaining a cerebrospinal fluid (CSF) sample from small patients. The Myelo-Nate® Kit provides the Myelo-Nate needle and components commonly needed to provide CSF samples.


  • Available with 1 inch or 1.5 inch 22 gauge or 1 inch 25 gauge LP needle.
  • Thin wall cannula design provides better flow of cerebral spinal fluid (CSF).
  • The needle's crystal clear hub provides visual detection of fluid flow.
  • The needle has an integrally ground stylet and a marker for bevel up orientation.
  • Vial lids can be sealed using one hand.


• To diagnose or rule out meningeal infection.
• To monitor efficacy of antibiotic therapy by examining CSF cell count, microbiology, and drug levels.
• To diagnose and treat subarachnoid hemorrhage.
• To drain CSF in prevention and treatment of communicating hydrocephalus associated with intraventricular hemorrhage.


• Superficial infection at or near puncture site.
• Lumbosacral anomalies.
• Increased intracranial pressure (ICP), due to:
a. Unilateral mass, such as tumor or hematoma.
b. Noncommunicating hydrocephalus
• Respiratory instability when the procedure may cause added compromise.
• Bleeding diathesis requires risk-benefit considerations.
