Intended Use
The ClearPoint Bone Screw Fiducials are intended to provide fixed reference point(s) in patients requiring stereotactic surgery in conjunction with CT imaging.
Device Story
ClearPoint Bone Screw Fiducials are titanium markers anchored into a patient's skull to serve as fixed reference points for stereotactic surgery. The kit includes five titanium fiducials, a bone screw holder, and a screwdriver. During the procedure, the surgeon uses the holder to position the fiducial orthogonally to the skull surface and drives it until flush. A central divot in the spherical head allows for precise centering of a navigation tool pointer. After placement, the patient undergoes CT imaging. The fiducials appear on the CT scans, enabling registration of pre-operative images to an optical navigation system. This process assists surgeons in accurately localizing targets during neurosurgical procedures, potentially improving surgical precision and patient outcomes.
Clinical Evidence
Bench testing only. Verification testing included physical, performance, and safety requirements, as well as simulated workflow testing for usability and effectiveness. Results demonstrated compliance with all design specifications and successful mitigation of identified risks.
Technological Characteristics
Materials: Titanium (fiducials), Polycarbonate (holder), Titanium/ABS/Nylon (screwdriver). Principle: Orthogonal bone-anchored markers. Form factor: 17mm length, spherical head with T8 Torx interface and central divot. Connectivity: None. Sterilization: Sterile, single-use.
Indications for Use
Indicated for patients requiring stereotactic surgery who need fixed reference points for CT imaging.
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.

#### 3. PREDICATE DEVICE
- Medtronic Unibody Bone Fiducials K033619
#### 4. DEVICE DESCRIPTION
The ClearPoint Bone Screw Fiducials are titanium bone screw fiducials that provide fixed reference points during neurosurgical procedures.
The ClearPoint Bone Screw Fiducial Kit is provided sterile and is composed of the following:
- 5x - ClearPoint Bone Screw Fiducials
- 1x Bone Screw Fiducial holder ●
- 1x Screwdriver ●
The Bone Screw Fiducial is made of titanium and comprised of a threaded portion that is screwed into a patient's skull and a non-threaded, exposed length that protrudes from the patient's head. The head contains a feature for compatibility with a T8 Torx screwdriver
{5}------------------------------------------------
and small divot positioned at the center of the spherical head which is used to center the pointer tip of a navigation tool.
The Bone Screw Holder is intended to assist in holding the Bone Screw Fiducials securely to the screwdriver during anchoring. This is accomplished by allowing the screwdriver to mate with the Bone Screw Fiducial without the Bone Screw Fiducial separating from the assembly therefore allowing it to be anchored to the skull.
#### న. INDICATIONS FOR USE
The ClearPoint Bone Screw Fiducials are intended to provide fixed reference point(s) in patients requiring stereotactic surgery in conjunction with CT imaging.
#### TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.
The ClearPoint Bone Screw Fiducials are substantially equivalent to the predicate device MedTronic UniBody Bone Fiducials, subject of K033619. They are identical in indications for use and both the proposed ClearPoint Bone Screw Fiducials and the predicate are bone screw fiducials made out of titanium. The devices are both comprised of a threaded portion that is screwed into a patient's skull and non-threaded, exposed length that protrudes from the patient's head and is topped by a rounded, spherical head. The top of the head of both devices is equipped with a feature for compatibility with a screwdriver.
Both the subject device and the predicate are placed orthogonally into the patient's skull prior to CT-imaging to serve as fixed reference points for registration. They are both visible under CT and a minimum of 4 of each are required for proper registration.
The difference between the ClearPoint Bone Screw Fiducials and the Unibody Bone Fiducials are minor design differences to the dimensions and the screwdriver compatibility. These differences do no introduce any risks of safety or efficacy. Table 12-1 provides a side-by-side comparison of the ClearPoint Bone Screw Fiducials to the Unibody Bone Fiducials.
