For full details, please refer to your System Manual.

Intended Use

Your Medtronic computer-assisted surgery system and its associated applications are intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. Their use is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure, such as the skull, a long bone, or vertebra, can be identified relative to a CT- or MR-based model, fluoroscopic images, or digitized landmarks of the anatomy.

Contraindications

Medical conditions which contraindicate the use of a Medtronic computer-assisted surgery system and its associated applications include any medical conditions which may contraindicate the medical procedure itself.

Warnings

Do not modify the StealthStation S7 System.

The system and its associated applications should be used only by qualified medical professionals who are thoroughly trained and experienced in performing surgery with Medtronic computer-assisted surgery systems.

The system and its associated applications should be used only as an adjunct for surgical guidance. They are not a replacement for the surgeon's knowledge, expertise, or judgment.

If system navigation seems inaccurate and recommended steps to restore accuracy are not successful, abort use of the system.

Accessory equipment connected to the analog and digital interfaces of the Medtronic computer-assisted surgery system must be certified according to the applicable IEC standards (e.g., IEC 60601-1 for medical equipment, UL60601-1, and CSA C22.2 No. 601-1-M90). Furthermore all configurations shall comply with the system standard IEC 60601-1-1 or the system requirements of Clause 16 IEC 60601-1: 3rd Edition. Any person who connects additional equipment to the signal input part or signal output part configures a medical system, and is therefore responsible for ensuring that the system complies with the requirements of the system standard IEC 60601-1-1 or the system requirements of Clause 16 IEC 60601-1: 3rd Edition. If in doubt, contact technical support or your local Medtronic Navigation, Inc. representative.

Some system components may contain batteries. Do not recharge or disassemble batteries. Do not dispose of batteries in fire. Observe local regulations concerning battery disposal.

Inspect all instruments before use. If visibly damaged, do not use the instrument.

Inspect all system components before use. If visibly damaged, do not use the system.

Discard before use any pre-sterilized component whose sterile packaging appears to be compromised.

Do not re-process, re-sterilize, or re-use any single-use device. Attempts to re-process or re-sterilize a single-use device may be ineffective and may compromise its structural integrity. Any re-use creates a risk of contamination which could result in patient injury, illness, or death.

There is currently no effective sterilization method for components that are tainted with the infectious agent that causes Creutzfeld-Jakob Disease (CJD). Therefore, you must discard immediately after surgery any components that come into contact with biologic material from patients who carry or are suspected to carry this infectious agent. As a precaution, drape all non-disposable components that could otherwise come into contact with such material.

Do not open sterile-barrier packages or containers until surgical use. At time of use, inspect barrier for breach. If the sterile barrier was breached before surgical use, reprocess all devices contained in the package.

The StealthStation S7 System is not intended to be operated on battery power alone while instruments are connected to a patient.

To reduce the potential of electrical shock, the operator should not simultaneously touch the patient and the system input/output panel, mouse, keyboard, or batteries.

To avoid risk of electrical shock, the StealthStation S7 System must only be connected to a supply mains with protective earth.

The StealthStation S7 System should not be connected to a wired network while in the patient vicinity to avoid electric coupling to non-medical equipment.

Do not transport the carts in an undocked position. Carts must be properly placed in the transport position and docked together before moving. To secure the system from unwanted lateral movement (for example, on an incline), lock all the castor wheels of the docked system.

The StealthStation S7 System Staff Cart contains a high fidelity stereo system for music playback from a user provided audio player. This system may be capable of sound levels which can lead to permanent hearing loss at high volume. The volume is controlled at the user provided audio player. For hearing safety, follow all warnings prescribed by the user provided player. If these warnings are not available or understood, do not exceed a 50% volume output from the audio player.

The following 2 warnings are from the AXIEM system manual:
