Intended Use

Horizontal-Vertical Lumbar Valve Systems are implantable devices used in the treatment of patients with communicating hydrocephalus to shunt cerebrospinal fluid (CSF) from the lumbar subarachnoid region to the peritoneal cavity. They provide controlled intraventricular pressure and CSF drainage in patients with hydrocephalus. The antechamber can be electively mounted in line with the Valve Unit to allow for CSF sampling or injections in the subarachnoid space. Percutaneous lumbar peritoneal shunting may be utilized in the treatment of communicating hydrocephalus. The Spetzler Shunt systems are designed to shunt CSF from the lumbar subarachnoid space to the peritoneal cavity. The shunt may be used for diagnosis, evaluation or treatment of normal pressure communicating hydrocephalus. A percutaneous lumbar peritoneal shunt is also useful in the management of persistent cerebrospinal fluid fistulas, bulging cranial and suboccipital decompressions and in transient CSF absorption defects, e.g. post-meningitic or post-hemorrhagic hydrocephalus. The In-Line Valve, available as a separate component of the system, is indicated for use where added resistance is desired to alleviate symptoms of low pressure in the small percentage of patients who, after normal drainage and in the normal course of treatment, develop such symptoms.

Device Story

Implantable differential pressure valve systems for communicating hydrocephalus; shunts CSF from lumbar subarachnoid region to peritoneal cavity. Operates via passive mechanical pressure thresholds; utilizes spring-actuated (lower pressure) and gravity-actuated (higher pressure) ball-in-cone mechanisms or double-slit valve/catheter resistance. Used by neurosurgeons in clinical settings. Modification adds MRI safety labeling (MR Conditional). Benefits include controlled CSF drainage and pressure management. No active components; no software/algorithms.

Clinical Evidence

No clinical data. Bench testing only, specifically to validate MR Conditional status per ASTM standards.

Technological Characteristics

Passive differential pressure valves; stainless steel modulus; spring-actuated and gravity-actuated mechanisms. MR Conditional per ASTM 2503-05. Testing performed per ASTM F2052 (displacement force), ASTM F2213 (torque), ASTM F2182 (RF heating), and ASTM F2119 (image artifacts).

Indications for Use

Indicated for patients with communicating hydrocephalus, normal pressure hydrocephalus, persistent CSF fistulas, bulging cranial/suboccipital decompressions, and transient CSF absorption defects (e.g., post-meningitic or post-hemorrhagic hydrocephalus) requiring CSF shunting from lumbar subarachnoid space to peritoneal cavity.

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.

# 4. Device Description

The Horizontal-Vertical Lumbar Valve and the Spetzler Lumbar-Peritoneal Shunt systems are implantable devices used in the treatment of patients with communicating hydrocephalus to shunt cerebrospinal fluid (CSF) from the lumbar subarachnoid region to the peritoneal cavity. Both are differential pressure valves designed to open when the difference between ventricular or lumbar pressure and outlet cavity pressure exceeds a certain threshold.

The primary issues affecting the safety and compatibility of passive implants in the MR environment concern magnetically induced displacement force and torque, radio frequency (RF) heating, and image artifacts. The addition of MRI Safety information to the labeling is intended to provide for safe use of the shunt systems by clarifying the conditions required to safely use these devices in an MR environment in a readily available, clear and concise manner, to healthcare providers.

## 5. Intended Use/Indications for use

## Horizontal-Vertical Lumbar Valve Systems

Horizontal-Vertical Lumbar Valve Systems are implantable devices used in the treatment of patients with communicating hydrocephalus to shunt cerebrospinal fluid (CSF) from the lumbar subarachnoid region to the peritoneal cavity. They provide controlled intraventricular pressure and CSF drainage in patients with hydrocephalus. The antechamber can be electively mounted in line with the Valve Unit to allow for CSF sampling or injections in the subarachnoid space.

#### Spetzler Lumbar Peritoneal Shunt Systems

Percutaneous lumbar peritoneal shunting may be utilized in the treatment of communicating hydrocephalus. The Spetzler Shunt systems are designed to shunt CSF from the lumbar subarachnoid space to the peritoneal cavity.

The shunt may be used for diagnosis, evaluation or treatment of normal pressure communicating hydrocephalus.

A percutaneous lumbar peritoneal shunt is also useful in the management of persistent cerebrospinal fluid fistulas, bulging cranial and suboccipital decompressions and in transient CSF absorption defects, e.g. post-meningitic or post-hemorrhagic hydrocephalus.

The In-Line Valve, available as a separate component of the system, is indicated for use where added resistance is desired to alleviate symptoms of low pressure in the small percentage of patients who, after normal drainage and in the normal course of treatment, develop such symptoms.

## 6. Substantial Equivalence Comparison

The Horizontal-Vertical Lumbar Valve and the Spetzler Lumbar-Peritoneal Shunt systems are identical to currently marketed predicate Horizontal-Vertical Lumbar Valve and Spetzler Lumbar-Peritoneal Shunt systems except for a labeling revision to add MRI safety information for the safe use of the devices in an MR environment.

# 7. Non-Clinical Testing

The Horizontal-Vertical Lumbar Valve Systems and Spetzler Lumbar Peritoneal Shunt Systems are identical in design. performance, and materials of composition to the currently marketed predicate systems. Since the proposed shunts and accessories are identical to the currently marketed shunts and accessories, all performance testing to the performance of the predicate devices also supports the proposed devices, and remains unchanged. Additional bench testing was performed to determine the safe use conditions for these products in the MR environment, as described below. Testing was also performed to confirm that the performance of these devices remains the same after use in an MR environment.

| DESIGN<br>VERIFICATION TEST | Acceptance |
|---------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Visual Inspection | All test samples shall be complete and free of visible damage. |
| Magnetically Induced<br>Displacement Force Test<br>ASTM F2052 | The amount of magnetically induced force on the device shall be less<br>than or equal to the force on the device due to gravity. |
| Magnetically Induced<br>Torque Test<br>ASTM F2213 | The amount of magnetically induced torque on the device shall be<br>less than or equal to the gravitational torque. |
| RF Heating Test<br>ASTM F 2182 | No portion of the implanted device shall exhibit an increase in<br>temperature of more than 2°C at a SAR of 2W/kg. |
| Image Artifact Test<br>ASTM F2119 | There is no acceptance criterion as per ASTM standard; this test is<br>performed to gather information relating to image artifacts caused by<br>the device. This information can be included in labeling. |

The non-clinical testing has demonstrated that the Horizontal-Vertical Lumbar Valve Systems and Spetzler Lumbar Peritoneal Shunt Systems are MR Conditional, as defined in the ASTM 2503-05 Standard, "Standard Practice for Marking Medical Devices and other items for Safety in the Magnetic Resonance Environment." This classification is appropriate for "an item which has been demonstrated to pose no known hazards in specific MR environment with specified conditions.

## 8. Clinical Testing

Clinical testing was not applicable for this modification.

{5}------------------------------------------------

## 9. Conclusions

The conclusions drawn from the nonclinical testing demonstrate that both the Horizontal-Vertical Lumbar Valve Systems and the Spetzler Lumbar Peritoneal Shunt Systems, with the addition of MRI Safety information in the labeling, are as safe and effective, and perform at least as safely and effectively, as the legally marketed predicate devices.
