The summary describes a robotic arm system controlled by a surgeon via a foot controller and custom software. While it involves computer control and calculations (e.g., calculating movements relative to a trocar point), there is no mention of AI, ML, or any learning or adaptive capabilities based on data. The control logic appears to be deterministic based on user input and pre-programmed calculations.
No
The device is described as a "Surgeon Controlled Arm" that holds and positions a laparoscope/endoscope and a magnetic controller. Its function is to assist in surgical procedures by controlling these instruments, not to directly treat a disease or condition itself.
No
Explanation: The device is described as a surgical arm system that holds and controls surgical tools (laparoscope/endoscope and magnetic controller) during minimally invasive interventions. Its function is to assist in surgical procedures by positioning instruments, not to diagnose medical conditions or provide diagnostic information.
No
The device description explicitly lists multiple hardware components, including two carts, surgeon-controlled arms, a scope holder, and a foot controller, in addition to the custom-programmed software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that the Surgeon Controlled Arm is used to hold and position a rigid laparoscope/endoscope and the Magnetic Controller of the Levita Magnetic Surgical System during minimally invasive interventions. This is a surgical assistance device used in vivo (within the living body) during a procedure.
- Lack of Diagnostic Testing: There is no mention of the device analyzing biological samples or providing diagnostic information. Its function is purely mechanical and control-based, assisting the surgeon with positioning instruments.
Therefore, the Surgeon Controlled Arm is a surgical device, not an in vitro diagnostic device.

Device Description
The Surgeon Controlled Arm for the Levita Magnetic Surgical System (MSS) comprises two collaborative surgeon-controlled arms, which along with their controllers, control software, and custom attachments, are intended to hold and control the Magnetic Controller of the commercially available MSS (most recently cleared under K191762) using an arm and to hold and control a commercially available endoscope with camera using the second arm. The design of the surgeon-controlled arms, referred to as the Scope Arm and the Magnet Arm, includes several redundant safety features that make them well suited for use with the MSS in the operating room environment, including hardware and software safety controls.
When mounted on the Scope Arm, an endoscope can be pivoted and translated as controlled by the user, while maintaining minimal motion at the point where the endoscope enters the patient's body via a standard trocar. Similarly, when mounted on the Magnet Arm, the Magnetic Controller can be moved to different positions on or away from the abdominal wall.
The Surgeon Controlled Arm includes the following components:
- (1) Two Carts, which are the Scope Cart and the Magnet Cart. Each Cart includes a surgeoncontrolled arm mounted on top of a moveable cart with custom attachments. One arm functions as a Scope Arm to hold a commercially available endoscope with endoscopic camera. The other arm functions as a Magnet Arm and includes a Magnet Holder to hold the Magnetic Controller of the MSS;
- (2) a Scope Holder for attachment and detachment of a compatible commercially-available endoscope to the end of the Scope Arm:
- (3) a Foot Controller for foot-actuated selection of the active arm and foot-actuated remote control for one of the arms at a time;
- (4) custom-programmed software, the Levita Custom Control Software Program.
The Surgeon Controlled Arm provides for computer control of a dual- arm device with motorized axes to hold and control the movements of a rigid endoscope and the Magnetic Controller of the Levita MSS during the minimally-invasive procedures cleared for the MSS (most recently cleared under K191762). The user selects the active arm and controls its movement using a Foot Controller. Only one arm is enabled for computer-controlled movement at any given time; while one arm is being moved, the other arm remains stationary. The user may also manually move the arms (i.e. hand guiding) at any time without the use of the Foot Controller.
For the Scope Arm, the reference point for scope movement is established as the Trocar Point and is set by the user, who positions the endoscope near the trocar inserted in the body opening (e.g. the abdominal fascial layer) and presses the Teach Trocar button on the Scope Adaptor. The Custom Control Software Program then calculates the required individual movements of the Scope Arm motorized axes relative to the Trocar Point in order to achieve the desired total movement of the endoscope with respect to the endoscope view. Once the Custom Control Software Program completes the Teach Trocar procedure, the Foot Controller is enabled, allowing the user in a standing position by the operating table to direct endoscope movement by using their foot to press on switches corresponding to the allowed movement directions.
For the Magnet Arm, the same arm hardware, software, and Foot Controller are employed to move the Magnetic Controller also in the same directions.

When mounted on the Scope Arm, an endoscope can be pivoted and translated as controlled by the user, while maintaining minimal motion at the point where the endoscope enters the patient's body via a standard trocar. Similarly, when mounted on the Magnet Arm, the Magnetic Controller can be moved to different positions on or away from the abdominal wall.
The Surgeon Controlled Arm includes the following components:
- (1) Two Carts, which are the Scope Cart and the Magnet Cart. Each Cart includes a surgeoncontrolled arm mounted on top of a moveable cart with custom attachments. One arm functions as a Scope Arm to hold a commercially available endoscope with endoscopic camera. The other arm functions as a Magnet Arm and includes a Magnet Holder to hold the Magnetic Controller of the MSS;
- (2) a Scope Holder for attachment and detachment of a compatible commercially-available endoscope to the end of the Scope Arm:
- (3) a Foot Controller for foot-actuated selection of the active arm and foot-actuated remote control for one of the arms at a time;
- (4) custom-programmed software, the Levita Custom Control Software Program.
The Surgeon Controlled Arm provides for computer control of a dual- arm device with motorized axes to hold and control the movements of a rigid endoscope and the Magnetic Controller of the Levita MSS during the minimally-invasive procedures cleared for the MSS (most recently cleared under K191762). The user selects the active arm and controls its movement using a Foot Controller. Only one arm is enabled for computer-controlled movement at any given time; while one arm is being moved, the other arm remains stationary. The user may also manually move the arms (i.e. hand guiding) at any time without the use of the Foot Controller.
For the Scope Arm, the reference point for scope movement is established as the Trocar Point and is set by the user, who positions the endoscope near the trocar inserted in the body opening (e.g. the abdominal fascial layer) and presses the Teach Trocar button on the Scope Adaptor. The Custom Control Software Program then calculates the required individual movements of the Scope Arm motorized axes relative to the Trocar Point in order to achieve the desired total movement of the endoscope with respect to the endoscope view. Once the Custom Control Software Program completes the Teach Trocar procedure, the Foot Controller is enabled, allowing the user in a standing position by the operating table to direct endoscope movement by using their foot to press on switches corresponding to the allowed movement directions.
For the Magnet Arm, the same arm hardware, software, and Foot Controller are employed to move the Magnetic Controller also in the same directions.
Indications for Use:
The Surgeon Controlled Arm is indicated for use to hold and position a rigid laparoscope/endoscope and the Magnetic Controller of the Levita Magnetic Surgical System in
5
minimally invasive interventions where the Levita Magnetic Surgical System is indicated for use.
Comparison of Intended Use and Technological Characteristics with the Predicate Device:
The subject and predicate devices have the same intended use. Both devices are surgeoncontrolled computer-driven systems whose function is to hold and position a rigid laparoscope/ endoscope. The subject device is only indicated for use with the Levita Magnetics Surgical System (most recently cleared under K191762).
The technological characteristics of the subject device and predicate device are substantially equivalent. Both devices have the same principles of operation using similar components: they provide software-based control of surgeon-controlled arm device(s) with motorized axes to hold and move a rigid commercially-available endoscope during minimally-invasive procedures. The user drives the electrically-powered device using a remote controller. The starting point of the movement for each case is saved as the trocar point from which the software calculates the required individual movements of the device arm's motorized axes to achieve the desired total movement. The user may also move the arm by hand guiding, without use of the remote controller. Neither predicate nor subject device interacts directly with any intra-cavity organ, but instead, holds instruments externally.
The following are differences in technological characteristics:
- . Both devices include a surgeon-controlled arm for controlling a rigid commerciallyavailable endoscope. The subject device additionally includes a second, similar arm for controlling the Levita Magnetics Magnetic Controller component of the Levita Magnetics Surgical System
- . The predicate device remote controller is controlled by hand and the subject device remote controller is controlled by foot.
- The subject device additionally includes a switch to allow the surgeon to determine the . active arm for remote control.
- The arm motion control specifications for the subject device, i.e. maximum velocities ● and acceleration, latency, range of motion, and safety limits, may differ from those of the predicate device, which are unknown.
Performance Data:
The following performance data were provided to demonstrate safety and effectiveness in support of substantial equivalence determination:
- Electrical safety and electromagnetic compatibility (EMC) performed to applicable . requirements of IEC 60601-1 and IEC 60601-1-2.

Summary:
7
K223673
The Surgeon Controlled Arm has the same intended use as the predicate device. In addition, it has similar technological characteristics; performance data demonstrates that any differences in technological characteristics do not raise different questions of safety or effectiveness. Therefore, the Surgeon Controlled Arm is substantially equivalent to the cleared predicate device.
