The device description focuses on mechanical and magnetic manipulation of tissue and does not mention any computational or data-driven components indicative of AI/ML.
No.
The device is described as a surgical tool designed to grasp and retract tissue for visualization and access during procedures, not to treat a disease or condition.
No
The device is designed for grasping and retracting tissue during surgical procedures to facilitate access and visualization, not for diagnosing medical conditions.
No
The device description clearly outlines physical hardware components: two hand-held instruments (Magnetic Grasper and Magnetic Controller) with specific mechanical functions (grasping, magnetic attraction). There is no mention of software being the primary or sole component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a surgical system designed to grasp and retract tissue during surgical procedures (laparoscopic cholecystectomy, bariatric procedures, prostatectomy). This is a surgical tool used in vivo (within the living body).
- Device Description: The description details hand-held instruments (Magnetic Grasper and Magnetic Controller) used for physical manipulation of tissue during surgery.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (blood, urine, tissue samples, etc.) in vitro (outside the living body) to provide information for diagnosis, monitoring, or screening.
IVD devices are used to perform tests on samples taken from the body to provide diagnostic information. This device is a surgical instrument used to facilitate the surgical procedure itself.

Device Description
The Levita Magnetic Surgical System is composed of two hand-held instruments, the Magnetic Grasper and external Magnetic Controller.
The Magnetic Grasper (sterile, single use), comprised of a distal detachable Grasper Tip attached to a Shaft with handle, is actuated via its pistol-grip handle with two distinct scissor-type motions to open and close the detachable Grasper Tip jaws. Once the Magnetic Grasper is inserted through a compatible
The Magnetic Controller (non-sterile, reusable) is a single unit with handles that is held external to the body and emits a magnetic field that attracts the Grasper Tip. Once the Grasper Tip is attached to the desired tissue and detached from the Shaft, the Magnetic Controller is placed external to the body to magnetically attract the Grasper Tip to manipulate the target tissue. Adjusting the distance between the Magnetic Controller and the Grasper Tip will modulate the magnetic attraction used for tissue retraction/mobilization. If desired, the user can connect the Magnetic Controller to a commercially available surgical support arm that is compatible with its arm mount.

The device is indicated for use in patients with a BMI range of 20-60 kg/m².
Comparison of Intended Use, Indications for Use and Technological Characteristics with the Predicate Device:
The subject and the predicate devices are identical in technological characteristics. The subject device differs from the predicate device by only a modifications for Use and the associated changes to the labeling. Results of clinical testing demonstrated that the differences in the indications for use do not raise different questions of safety and effectiveness, and, therefore, the subject device has the same intended use as the predicate device.

Page 3 of 6
The subject and predicate device share identical technological characteristics:
- Both devices are composed of two hand-held instruments: a Magnetic Grasper comprised of a detachable Grasper Tip and a Shaft, and an external Magnetic Controller.
- . The principles of operation remain unchanged. For both devices, the Magnetic Grasper is actuated manually using the handle of the Shaft to grasp and release tissue; and the Grasper Tip is controlled manually by the handle or the external Magnetic Controller to retract tissue.
- . The design, features and materials remain unchanged. The patient-contacting materials of the Magnetic Grasper meet biocompatibility requirements per applicable sections of ISO 10993-1. The Magnetic Controller is not patient-contacting.
As such, the design, materials and function of the subject Magnetic Surgical System are substantially equivalent to the predicate Magnetic Surgical System.
Performance Data:
There were no technological changes to the subject device, thus no bench, animal, electromagnetic compatibility testing, sterilization testing or biocompatibility testing was required.
Clinical performance data demonstrated the subject device is as safe and effective as the predicate device in grasping and retracting soft tissue and organs in prostatectomy procedures.
Special Controls:
The Magnetic Surgical System is subject to the special controls described in §21 CFR 878.4815. These special controls are stated below. Compliance with these requirements has been met as noted in the italicized text below each requirement.
- (1) In vivo performance data must demonstrate that the device performs as intended under anticipated conditions of use. Testing must demonstrate the ability of the device to grasp, hold, retract, mobilize or manipulate soft tissue and organs.
Clinical performance data from a prospective clinical study of 30 subjects with five participating surgeons was conducted at Fundacion Arturo Lopez Perez in Santiago, Chile to address this special control.
As shown in the study summary table below (Table A), the device was successfully used for retraction of the prostate and periprostatic tissue in prostatectomy procedures. Results of the clinical study met all safety and effectiveness endpoints, demonstrating that the Magnetic Surgical System can be used in robotic-assisted laparoscopic prostatectomy surgery in a safe and effective manner. Investigators reported that adequate retraction was achieved since it was not necessary to replace the MSS with another instrument to retract the prostate during the procedure. There were no cases of severe or serious adverse events related to the reported clinical performance data from the prospective study demonstrated that the device performed as intended in prostatectomy procedures.

- Non-clinical performance data must demonstrate that the system performs as intended (2) under anticipated conditions of use. The following performance characteristics must be tested:
- (a) Magnetic field strength testing characterization to identify the distances from the magnet that are safe for patients and users with ferromagnetic implants, devices or objects.
- (b) Ability of the internal surgical instrument(s) to be coupled, de-coupled, and recoupled with the external magnet over the external magnet use life.
The modifications that are the subject of this submission do not change the magnetic field strength or coupling of the internal surgical instrument with the external magnet. Therefore, previously conducted nonclinical performance testing that demonstrated that the device performs as intended under the anticipated conditions of use applies here.
