More Information

No
The summary describes a navigated surgical instrument that uses electromagnetic tracking to display its position on pre-operative scans. There is no mention of AI or ML being used for image analysis, navigation, or any other function.

No.
A therapeutic device is one that treats a disease or condition. This device is described as an instrument to "manipulate, dissect and/or remove tissue, cartilage and bone during surgical procedures," which are surgical tools, not therapeutic actions in themselves.

No

The device is described as an instrument intended for manipulating, dissecting, and removing tissue, cartilage, and bone during surgical procedures. Its function is to aid in surgical treatment, not to diagnose a condition. While it is used with a navigation system that displays over CT/MRI scans to confirm access and locate anatomical structures, this is for surgical guidance, not for diagnostic purposes.

No

The device description clearly states the TruDi™ Curette is a physical instrument with a shaft, curette cup, and magnetic sensor, and is sold in sterile packaging with a bending tool. It is a hardware device used in conjunction with a navigation system.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue samples) to provide information about a person's health. This testing is done outside of the body (in vitro).
  • TruDi™ Curette Function: The TruDi™ Curette is a surgical instrument used during a surgical procedure inside the patient's body. It is used to manipulate, dissect, and remove tissue, cartilage, and bone. Its primary function is mechanical manipulation and removal of tissue, aided by navigation for precise placement.
  • Navigation System: While it works with a navigation system that uses pre-operative imaging (CT/MRI), the curette itself is not performing a diagnostic test on a sample. The navigation system helps the surgeon guide the instrument, but the instrument's action is surgical, not diagnostic.

The description clearly indicates it's a surgical tool used in vivo (within the living body) during a procedure, not a device for testing samples in vitro.

| [807.92(a)(6)] Technical Characteristics | |
| Technological
Characteristics: | The TruDi™ Curette is substantially equivalent in technological characteristics,
as there are no significant differences in fundamental scientific technology or
other features as compared to the predicate device, KARL STORZ EM Frontal
Sinus Curette (K161555) and reference device, TruDi™ Probe (K193453). |

Both the subject and predicate devices are electromagnetically-navigated instruments, which are intended to be used with their compatible EM navigation systems to manipulate, dissect and/or remove tissue, cartilage and bone during surgical procedures in ENT and ENT skull base surgery. Similar to the predicate device, the subject device incorporates a sensor within the distal shaft, which is tracked by the navigation system. The location of the distal tip of the device is identified by the navigation system and displayed in real-time view over the patient's pre-operative CT/MRI scan to confirm access, and to locate anatomical structures during ENT and ENT skull base surgery.

The primary differences between the subject and predicate device are the following:

  • The subject device is a single-use instrument, whereas the predicate ● device is reusable for up to 30 uses.

The Acclarent logo features the company name in a combination of black and purple, with a curved design above the text.

  • The subject device is packaged with a bending tool, whereas the predicate device is not.
  • . The subject device consists of one configuration (straight 0°), whereas the predicate devices consists of two configurations (curved 55°and 90°).
  • . The distal shaft of the subject device is malleable and can be formed with the provided bending tool per physicians' preference, whereas the predicate device has a rigid distal shaft.
  • . The sensor in both the subject and predicate devices are located within the distal shaft of the devices. While the sensor in the subject device is located ~1cm away from the distal tip, the sensor in the predicate device is located ~6cm away from the distal tip.
  • . The total length of the subject device is 24cm, whereas the total length of the predicate device is 18cm.
  • . The handle construction of subject device consists of polycarbonate material, whereas the predicate device handle consists of stainless steel.

However, these differences do not raise new concerns of safety and effectiveness for the subject device as demonstrated by performance testing and design validation testing (simulated use testing).

Additionally, the technological characteristics of the subject device are similar to the reference device. The subject device utilizes identical sensor subassembly (sensor, wire, PCB, and connector) and navigation platform as the reference device. Similar to the reference device, the sensor of the subject device is located at the distal tip for instrument tracking. See Table 1 for a comparison of the technological characteristics between the subject device and the predicate/reference devices.

The difference in the working length
of the predicate and subject devices is
based on several Voice of Customer
(VOC) activities and has been
successfully validated during design
validation testing. This difference
improves usability of the subject
device and does not introduce any
additional risks.
The differences between the handles
