No
The summary describes accessory instruments for neuromonitoring systems, focusing on electrical stimulation and signal conduction properties. There is no mention of AI, ML, image processing, or data analysis that would suggest the use of these technologies. The performance studies are related to biocompatibility, sterility, electrical properties, and safety, not algorithmic performance.

No
The device is used to assist surgeons in locating spinal nerves and facilitating surgical procedures, not to treat a disease or condition. It is an accessory instrument for neuromonitoring systems.

Yes

The device assists in locating spinal nerves by providing proximity information through electrical stimulation, which is a diagnostic function.

No

The device description explicitly states that the device includes physical instruments made of surgical grade stainless steel and ABS, and describes testing related to the physical properties of these instruments (biocompatibility, sterility, electrical resistance, etc.).

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states the device is used by a surgeon to assist in locating spinal nerves by providing proximity information during surgical procedures. This is an in-vivo application, meaning it's used within a living organism.
  • Device Description: The description reinforces that these are accessory instruments used with neuromonitoring systems to deliver electrical stimulation to assist in locating spinal nerves during intraoperative neurological monitoring. This is a surgical tool, not a diagnostic test performed on samples outside the body.
  • Lack of IVD Characteristics: The description does not mention analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. IVDs are designed to diagnose diseases or conditions based on tests performed on these types of samples.

The device is a surgical accessory used for intraoperative neuromonitoring, which is a procedure performed on a patient during surgery. This falls outside the definition of an In Vitro Diagnostic device.

Externally communicating patient
contacting with tissue/bone/dentin
contact;limited exposure ≤24hrs | All samples passed acceptance criteria
testing on subject device. The device
demonstrated it had an acceptable
biocompatibility profile commensurate
with anticipated exposure. |
| Sterility and
Packaging | Testing appropriate for the sterile packaged LITE
Y-Needles device was performed as per the 2016
FDA Guidance "Submission and Review of Sterility
Information in Premarket Notification (510(k))
Submissions for Devices Labeled as Sterile", are
sterilized using an "Established Category A"
sterilization method, Gamma Radiation. This
testing included but not limited to the following:
Physical stressing | All samples passed acceptance criteria
testing on subject device and
demonstrated that packaging and
sterilization was appropriate for single
use, sterile packaged devices. |
| Summary of the Performance Data | | |
| Test | Test Method Summary | Results |
| | Visual inspection Seal strength Bubble emission Packaging aging | |
| EMC and Safety | Stryker Spine conducted Safety and EMC testing
to evaluate the electrical performance and safety
of the ES2 accessory instruments used for
neuromonitoring applications. Safety tests were
conducted and/or evaluated per IEC 60601-1. | EMC risk evaluation per IEC 60601-1
demonstrated that the subject device
did not present a new worst case and
met all applicable UL Safety and EMC
tests. |
| Stationary
Potential
Generation Test | The purpose of this test is to verify that a potential
stationary potential(s) produced when applying
electrical current to the LITe Y-300 and Y-400
needles are not sufficiently large so false positive is
not produced when used for neuromonitoring.

The LITe® Y-Needle was placed in a biological
simulant and connected to the stimulation probe.
Recording probes and thermocouples were placed
in the simulant.

The LITE® Y-Needle was stimulated at clinical
current levels for 60 seconds. Using a fixed sweep
trace capture, the average stationary potential was
obtained for the full duration. | The passing results of the stationary
potential testing demonstrated that the
LITe® Y-Needles generated a stationary
potential less than or equal to the
predefined acceptance criteria. |
| Electrical
Resistance | The purpose of this test is to ensure the resistive
and conduction sections of the needles are
appropriate to allow for current conduction and
current insulation during neuromonitoring.

Probes were connected to the conductive and
insulating portions of the device. The resistance of
the conductive portion was measured. The
resistance of the insulating portion was measured. | The passing results of the resistance test
demonstrated that the LITe® Y-Needles
experienced a resistance measurement
less than or equal to the predefined
acceptance criteria for conductivity and
greater than or equal to the predefined
acceptance criteria for the resistivity. |
| Current Variance | The purpose of this test is to verify the degree of
current deviation along the axial length of the
LITe® Y-Needle. This testing ensures the signal is
conducted in a consistent manner as delivered by
the neuromonitoring device.

The LITe® Y-Needles were connected to
stimulation probes at the conductive locations of
the device. Clinical current levels were applied to
the device for 10seconds, 100seconds, and 500
seconds. The transmitted current was recorded
and compared to the applied current. | The passing results of the current
deviation test demonstrated that the
LITe® Y-Needles experienced a current
deviation less than or equal to the
predefined acceptance criteria. |
| Summary of the Performance Data | | |
| Test | Test Method Summary | Results |
| Signal Conduction
(amplitude

signal loss the axial length of the LITe® Y-Needle.
This testing ensures the signal is conducted in a
consistent manner as delivered by the
neuromonitoring device.

The LITe® Y-Needles were connected to a
stimulation probe at the conductive locations of
the device. The device was stimulated using clinical
current levels and the percentage difference of the
power input was compared to the transmitted
signal wave. | The passing results of the signal loss test
demonstrated that the LITe® Y-Needles
experienced a signal loss less than or
equal to the predefined acceptance
criteria. |
