Intended Use

The Neuron Therapeutics Inc., 14-Gauge Lumbar Puncture Set is indicated for temporary access to the lumbar subarachnoid region to drain cerebrospinal fluid (CSF) and other fluids of similar physical characteristics.

Device Story

The 14-Gauge Lumbar Puncture Set provides temporary access to the lumbar subarachnoid space for CSF drainage. The set includes a 14-gauge polyurethane catheter (30 cm length, 1.25 mm ID, 1.74 mm OD) featuring 35 fenestrations to reduce flow resistance and occlusion risk, a 14-gauge Extra-Thin Wall Touhy needle, a 45 cm stainless steel J-tip guidewire, a 6-French Touhy-Borst connector, and accessories (dressing, anchor, drape). The physician inserts the catheter into the subarachnoid space using the needle and guidewire. Catheter markings at 1 cm intervals assist in distal tip placement. The device is intended for single-use. The output is the facilitated drainage of CSF, which is collected or monitored via external equipment connected to the Touhy-Borst connector. This procedure aids in managing CSF pressure or fluid removal, benefiting patients requiring temporary subarachnoid access.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Polyurethane catheter; 14-gauge Extra-Thin Wall Touhy needle; stainless steel J-tip guidewire; 6-French Touhy-Borst connector. Features 35 fenestrations and 13 location markings at 1 cm intervals. Sterile, single-use, tamper-evident packaging.

Indications for Use

Indicated for temporary access to the lumbar subarachnoid region for drainage of cerebrospinal fluid (CSF) or fluids with similar physical characteristics in patients requiring such access.

Regulatory Classification

Identification

A central nervous system fluid shunt is a device or combination of devices used to divert fluid from the brain or other part of the central nervous system to an internal delivery site or an external receptacle for the purpose of relieving elevated intracranial pressure or fluid volume (e.g., due to hydrocephalus). Components of a central nervous system shunt include catheters, valved catheters, valves, connectors, and other accessory components intended to facilitate use of the shunt or evaluation of a patient with a shunt.

Predicate Devices

• CODMAN Lumbar External Drainage Catheter with Touhy Needle (K964923)

## Device Classification

This device has been placed in a Class II for Central Nervous System shunt and components per 21 CFR § 882.5550.

## Statement of Substantial Equivalence

The 14-Gauge Lumbar Catheter is the component of the14-Gauge Lumbar Puncture Set subject to 510(k) approval. Neuron Therapeutic Inc.'s (NT) 14-Gauge Lumbar Catheter is substantially equivalent to the CODMAN Lumbar External Drainage Catheter with Touhy Needle that is currently marketed in the United States under 510(k) No. K964923. NTI's 14-Gauge Lumbar Catheter and 14-Gauge Lumbar Puncture Set have the same intended use, design characteristics, and similar methods of manufacture as the CODMAN Lumbar External Drainage Catheter with Touhy Needle.

#### Indications for Use

The Neuron Therapeutics Inc., 14-Gauge Lumbar Puncture Set has an substantially equivalent indication for use as the Codman Lumbar Drainage Catheter Kit. Both are indicated for temporary access to the lumbar subarachnoid region to drain cerebrospinal fluid (CSF) and other fluids of similar physical characteristics.

#### Physical Description

The Neuron Therapeutics 14-Gauge Lumbar Puncture Set, part number PN1000735, consists of a 14-Gauge Lumbar Catheter Kit, a Transparent Tegaderm™ Dressing, a Suture-less Catheter Anchor, and a Sterile Drape. These individual, sterile packaged components are provided in sealed tamper-evident packaging for single-use.

The 14-Gauge Lumbar Catheter Kit, part number PN1000737, contains a single 30 cm coiled lumbar catheter with an inner diameter of 1.25 mm, an outer diameter of 1.74 mm and 35 fenestrations. The shorter length, larger diameter and higher number of fenestrations of the catheter allow for decreased flow resistance and higher liquid flow rates. The higher number of fenestrations decreases the possibility of occlusion of the catheter during use. The catheter is constructed of polyurethane to provide resistance to kinking or collapsing. The catheter has13 location markings positioned at 1 cm intervals to assist the physician in identifying the location of the distal end of the catheter in the subarachnoid space. Special

{2}------------------------------------------------

markings are provided to indicate the location of the catheter tip, the proximal fenestration and the coiled shaft as they exit from the needle tip.

The 14-Gauge Lumbar Catheter Kit also contains a 15.0 cm, 14-gauge Extra-Thin Wall Touhy Needle and a 45 cm stainless steel flexible J-tip guidewire for inserting and guiding the catheter into the lumbar subarachnoid space. A 6-French Touhy-Borst Connector is also included for connection to equipment for patient monitoring or fluid collection.
