Physician uses Controller (leader-follower mechanism) to command catheter insertion, retraction, and articulation. Used in hospital settings for diagnostic/therapeutic procedures. Enables fiducial marker placement. System modified to support remote software updates via secure network. Output provides visualization and navigation assistance to guide biopsy or marker placement; does not perform diagnosis. Benefits include precise navigation to peripheral lung targets.

Clinical Evidence

No clinical data provided. Substantial equivalence supported by risk analysis and literature-derived patient factors for pediatric population.

Technological Characteristics

Electromechanical system; servomechanism leader-follower architecture. Components: Planning Laptop, System Cart, Controller, articulating catheter, vision probe, biopsy needles. Connectivity: Secure network for remote software updates. Software-controlled. No changes to materials or hardware from predicate.

Indications for Use

Indicated for adult and pediatric patients (≥5 ft/152.5 cm and ≥102 lbs/46 kg) to assist in navigating a catheter and endoscopic tools in the pulmonary tract using endoscopic visualization of the tracheobronchial tree for diagnostic and therapeutic procedures, including fiducial marker placement. Does not make a diagnosis. PlanPoint Software uses patient CT scans to create a 3D plan of the lung and navigation pathways.

Regulatory Classification

Identification

A bronchoscope (flexible or rigid) and accessories is a tubular endoscopic device with any of a group of accessory devices which attach to the bronchoscope and is intended to examine or treat the larynx and tracheobronchial tree. It is typically used with a fiberoptic light source and carrier to provide illumination. The device is made of materials such as stainless steel or flexible plastic. This generic type of device includes the rigid ventilating bronchoscope, rigid nonventilating bronchoscope, nonrigid bronchoscope, laryngeal-bronchial telescope, flexible foreign body claw, bronchoscope tubing, flexible biopsy forceps, rigid biopsy curette, flexible biopsy brush, rigid biopsy forceps, flexible biopsy curette, and rigid bronchoscope aspirating tube, but excludes the fiberoptic light source and carrier.

Dear Sandi Mar:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

tracheobronchial tree for diagnostic and therapeutic procedures. It consists of a Planning Laptop with PlanPoint™ Software, a System Cart with System Software, a Controller, Instruments, and Accessories. The IF1000 Instruments include the Ion™ Fully Articulating Catheter, the Ion™ Peripheral Vision Probe, and the Flexision™ Biopsy Needles.

The Planning Laptop is a separate computer from the System Cart and Controller. A 3D airway model is generated from the patient’s chest CT scan using the PlanPoint™ Software.

The System Cart contains the Instrument Arm, electronics for the follower portion of the servomechanism, and two monitors. The System Cart allows the user to navigate the Catheter Instrument with the Controller, which represents the leader in the leader-follower relationship. For optimal viewing, the physician can position the monitors in both vertical and horizontal axes.

The Controller is the user input device on the Ion™ Endoluminal System. It provides the controls to command insertion, retraction, and articulation of the Catheter. The Controller also has buttons to operate the Catheter control states.

The IF1000 System and PlanPoint Software are modified to enable Remote Software Updates from the Intuitive server via secure network communication.

# 7. INDICATIONS FOR USE COMPARISON

The Indications for Use statement of the subject device is modified to include the pediatric population. Minimum patient factors that represent the appropriate pediatric population that can safely undergo an Ion procedure were derived from clinical literature. The inclusion of pediatric use to the Indications for Use does not change the objective intent of the device and the substantial equivalence can be demonstrated by confirmation through risk analysis that use in an indicated pediatric population does not present new issues of safety or efficacy. The intended use remains the same.

# 8. CONCLUSIONS

The basis for this submission is the modification of the Indications for Use of the Ion Endoluminal System, Model IF1000 to include the pediatric population. No new risks or changes to the existing risks or safety profile of the device are prompted by this modification. Additionally, there are no new verification or validation activities required to support this modification. The subject device modification does not raise new questions of safety and effectiveness of the device.

Based on the intended use, operating principles, technological characteristics, and performance testing, the subject device, Ion Endoluminal System, is substantially equivalent (SE) to the predicate device (K242070).
