About this User’s Manual This manual supports the CRW® Precision Arc Stereotactic System, and is not intended to be a clinical medical document. This publication details the mechanical/functional features of the system and describes how to properly assemble, use, sterilize and maintain the equipment in the system. Read and become familiar with these instructions before using the system in surgery.

About CRW System Compatibility The CRW stereotactic system is a target-centered system that can be configured to be CT-only or CT/MR compatible.

Indications for Using the CRW System Standard Stereotactic Procedures The CRW stereotactic system is a multi-purpose system used for localizing intercranial targets for precisely directing instruments such as: • Biopsy forceps • RF lesioning electrodes • Deep brain electrodes • Recording and stimulating electrodes • Hematoma evacuators • Endoscopes Note

Localization is performed using CT or MR imaging.

Chapter 1 • About the CRW® Precision Arc Stereotactic System • 1

Contraindications for Using the CRW System •T he head ring is contraindicated for infants whose coronal sutures have not yet closed. •T he CRW system is contraindicated for patients with Creutzfeldt–Jakob disease.

Single Use Precautions Single use devices are used with the CRW stereotactic system. The following precautions should be taken:

For single patient use only. The Disposable Head Ring Screws, Long and Short (DHRSS5, DHRSL5) are designed as single-use, disposable products and should not be re-sterilized or reused. Re-sterilization and reuse may result in dullness of the screw, leading to potential head ring movement, and cross contamination. Any Disposable Head Ring Screw, once used, should be discarded according to hospital policy.

For single patient use only. The Apuzzo Stereotactic Drapes (ASD1 and ASD1B) are designed as single-use, disposable products and should not be re-sterilized or reused. Reuse of this device may result in cross contamination or compromised sterility of the drape and sterile field. Any drape, once used, should be discarded according to hospital policy.

For single patient use only. The Nashhold Biopsy Needle (NBND) is designed as a single-use, disposable product and should not be re-sterilized or reused. Re-sterilization may result in impaired function (e.g. dulling of the cutting window, loss of vacuum) and cross contamination. Any needle, once used, should be discarded according to hospital policy.

For single patient use only. The CRW BiopsyPlus Kit (CRWBP) is designed as a single-use, disposable product and should not be re-sterilized or reused. Re-sterilization may result in impaired function (e.g. dullness of cutting window, loss of vacuum, inaccuracy of bushing) and cross contamination. Once used, the kit should be discarded according to hospital policy.

2 • Chapter 1 • About the CRW® Precision Arc Stereotactic System

Accuracy of the CRW System User error in the cursor placement and slice positioning contribute to the total application error. The accuracy in the lateral and AP dimension is ±2mm. Error in the vertical direction may be as large as the thickness of the scan slice (2 or 4 mm). The intrinsic mechanical accuracy of the arc is better than 0.5 mm, as determined in bench testing. To ensure proper accuracy and function of the CRW system, do not subject any of the CRW system’s parts or accessories to any forces that may affect its use or calibration.

Always inspect the CRW system’s parts and accessories prior to use. If any of the parts or accessories are damaged in a way that may potentially affect the system’s accuracy or function, please return the system to Integra for service (see page 79 for packaging instructions).

The CRW system should be viewed as adjuncts to the skills of the surgeon.

Using the CRW System with Electrosurgical Devices If the CRW system is to be used with a ground–referenced electrosurgical device (monopolar or bipolar electrode), the head ring should not contact the patient. Maintain a gap (at least 1/4 inch) between the head ring and the patient’s body. • Follow safety procedures consistent with the use of anesthetizing gases when using the arc system with electrosurgical equipment. • Review the system and its accessories prior to surgery to ensure that all items are available and functional.
