A special adapter is available to affix the endoscope.

Device Story

Neuroendoscope set for intracranial procedures; includes sheath, obturators, telescope, forceps, scissors, electrodes, suction needle, and adapters. Enables direct visualization, diagnosis, and therapy through single burr hole. Features working, irrigation, and aspiration channels; compatible with stereotactic frames via special adapter. Rigid telescopes allow penetration of small openings and viewing around corners. Used by neurosurgeons in clinical settings. Provides visual control for procedures like cyst fenestration, shunt placement, and lesion biopsy. Benefits patient by enabling minimally invasive intracranial access and therapeutic intervention.

Clinical Evidence

Clinical tests were performed by Eric Weber, MD, PhD, at the University of South Alabama under protocol # 92-105. No specific performance metrics or results were provided in the summary document.

Technological Characteristics

Rigid and flexible endoscope system for single burr hole access. Includes irrigation, aspiration, and working channels. Features interchangeable rigid telescopes with varying viewing angles. Designed for electrical isolation; insulation bonding tested for abrasion/flaking resistance. Thermal safety verified. Compatible with stereotactic frames.

Indications for Use

Indicated for patients undergoing intracranial procedures requiring direct visualization, diagnosis, or therapeutic intervention, including cyst fenestration, shunt placement, intraventricular coagulation, ventriculostomy, and biopsy of ventricular lesions.

Regulatory Classification

Identification

## 2.0 Intended Use

The device is intended for use for direct visualization, diagnosis and therapeutic application during intracranial procedures, such as

- cyst fenestration
- shunt placement
- intraventricular coagulation
- ventriculostomy of the 3rd ventricle when the aqueduct is obstructed
- coagulation of small intraventricular lesions
- biopsy of lesions which lead to the stricture of a ventricle

The instrument simultaneously permits visual control and utilization of a working, an irrigation, and an aspiration channel.

The Neuro-Endoscope can be used with or without a stereotactic frame. A special adapter is available to affix the endoscope.

## 3.0 Technological Characteristics

- Procedure can be performed through one single burr hole.
- Uses a small flexible endoscope able to pass through the working channel and the possibility of using different rigid telescopes with various viewing angles.
- Rigid telescopes can be advanced in a second stage beyond the tip of the sheath to penetrate small openings or channels and to “look around the corner”.

## 4.0 Substantial Equivalence

The Richard Wolf Neuroendoscopy Set is substantially equivalent to the following devices:

- Codman and Shurtleff, Inc.’s Gaab Neuroendoscope System
- Karl Storz Auero Neuro-Endoscope System
- Aesculap, Inc. Neuroendoscope

All devices have the same intended use.

## 5.0 Performance Data

- To ensure that the user is electrically isolated from the device, the instruments and connection cables are designed so that the connection instrument/cable overlaps.
- Abrasion/Flaking testing was performed to assure the integrity and bonding of the insulation material to the instruments.
- Testing was performed to verify thermal safety. Thermal damage is unlikely to occur using the Richard Wolf Neuroendoscopy Set.

## 6.0 Clinical Tests

Clinical tests were performed by Eric Weber, MD, PhD, at the University of South Alabama under protocol # 92-105.
