Intended Use

The StealthStation® System is intended as an aid for precisely locating anatomical structures in either open or percutaneous procedures. The StealthStation® System 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 or fluoroscopy images of the anatomy. Example procedures include, but are not limited to: Cranial Procedures: Cranial biopsies. Tumor resections. Craniotomies/ Craniectomies. Skull base procedures. Thalamotomies/Pallidotomies. Spinal Procedures: Spinal implant procedures, such as pedicle screw placement. ENT Procedures: Transphenoidal procedures. Intranasal procedures. Sinus procedures, such as Maxillary antrostomies, Ethmoidectomies, Sphenoidotomies./Sphenoid explorations, Turbinate resections, and Frontal sinusotomies.

Device Story

StealthStation System is a frameless stereotactic navigation platform; aids surgeons in precisely locating anatomical structures during open or percutaneous procedures. Inputs include CT, MR, or fluoroscopic images of patient anatomy. System registers rigid anatomical structures (skull, long bone, vertebra) to these images; provides real-time spatial tracking. Used in OR by surgeons; assists in cranial biopsies, tumor resections, craniotomies, spinal implant placement (e.g., pedicle screws), and ENT procedures (e.g., sinusotomies). Output is visual guidance on display; allows surgeon to correlate instrument position with patient anatomy. Benefits include improved surgical precision and anatomical localization.

Clinical Evidence

Clinical study data originally submitted in K954276 was reviewed to support the expanded indications for use. No new clinical testing was performed for this specific indications modification.

Technological Characteristics

Frameless stereotactic navigation system. Utilizes CT, MR, or fluoroscopic image data for anatomical registration. System architecture remains consistent with previously cleared StealthStation® predicates. No changes to hardware or sensing principles.

Indications for Use

Indicated for patients requiring stereotactic surgery where rigid anatomical structures (skull, long bone, vertebra) can be registered to CT, MR, or fluoroscopic images. Applicable for cranial, spinal, and ENT surgical procedures.

Regulatory Classification

Identification

A stereotaxic instrument is a device consisting of a rigid frame with a calibrated guide mechanism for precisely positioning probes or other devices within a patient's brain, spinal cord, or other part of the nervous system.

Predicate Devices

• StealthStation® System (K954276)
• StealthStation® System (K972398)
• StealthStation® System (K974187)

Dear Mr. White:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
