Intended Use

The EpiFinder is intended for use, in between a luer Loss of resistance (LOR) syringe and an epidural needle, to verify the needle tip placement in the epidural space as a secondary indicator adjunctive to the LOR technique.

Device Story

EpiFinder is a sterile, single-use device used during epidural procedures to confirm needle tip placement in the epidural space. It attaches between a standard 18G epidural needle and a LOR syringe. The device features a blunt-tip, spring-loaded probe that detects tissue resistance changes as the needle advances. A microcontroller measures probe spring contraction; LED indicators on the housing provide visual feedback to the physician. It is designed to be used adjunctively with the standard manual LOR technique. By providing an independent secondary signal, it assists the practitioner in identifying the epidural space, potentially improving procedural accuracy and patient safety. It is intended for use by clinicians in a clinical setting.

Clinical Evidence

Clinical evidence includes a single-arm, open-label multicenter trial (n=31 adults) for lumbar epidural steroid injections. The study confirmed the device's safety and performance in identifying the epidural space. An animal study (pigs) compared EpiFinder-assisted LOR to standard LOR, demonstrating effectiveness with one adverse event. Human factors evaluation (n=26: 16 anesthesiologists, 10 student nurse anesthetists) confirmed safe use and high user satisfaction with no use-related hazards. Bench testing verified mechanical integrity, biocompatibility (ISO 10993), and electrical safety (IEC 60601).

## A. INTENDED USE/INDICATION FOR USE

The EpiFinder is intended for use, in between a luer Loss of resistance (LOR) syringe and an epidural needle, to verify the needle tip placement in the epidural space as a secondary indicator adjunctive to the LOR technique.

## B. DEVICE DESCRIPTION

The EpiFinder is intended to be used in conjunction with a standard epidural LOR technique as an independent secondary confirmatory indicator, giving the practitioner a clear visual signal that the needle tip has entered the epidural space. The EpiFinder is a sterile, single-use device that is used during epidural procedures. The device works with a standard loss of resistance (LOR) syringe and an epidural needle (18G) to verify that the needle tip placement is in the epidural space in patients ages 18 or older.

The EpiFinder consists of a blunt tip spring-loaded probe that is installed into a standard epidural needle, and a plastic housing that is composed of a linear actuator, a sensor, and a microcontroller that measures the probe spring's contraction. The EpiFinder is attached to a Tuohy needle that has been inserted into the patient. The device has built in "wings" to help advance the needle, if the practitioner wishes to use them. As the needle advances forward, there are LED indicator lights on the housing that give feedback to the operator as to when the epidural space is entered, as input to the user in conjunction with the standard LOR technique.

{4}------------------------------------------------

### C. SUMMARY OF TECHNOLOGICAL CHARACTERISTICS

Both the subject and predicate devices operate in conjunction with a standard luer LOR syringe and epidural needle to enable detection of when the needle has entered the epidural space. Both devices detect entry into the epidural space via tissue resistance differentiation, which is based on the wellknown and widely used loss of resistance technique. In addition, both are comprised entirely or largely of medical-grade polymers.

The primary technological difference between the subject and predicate devices is that the predicate device incorporates an expandable membrane which deflates while the needle tip enters the epidural space and does not enable utilization of loss of resistance (LOR) technique by using the syringe, (though the reference device does). In contrast, the subject device enables a standard LOR technique (primary indicator) and a secondary indicator that uses a spring-loaded probe which expands while the needle tip enters the epidural space. The subject device provides a secondary indicator as to when the epidural space is entered while the predicate device replaces the LOR technique with its own indicator (membrane deflation).

A table comparing the key features of the subject, predicate, and reference devices is provided below.

## D. PERFORMANCE DATA

Final verification/validation testing of the EpiFinder device is summarized below. The results were supportive of the device's safety and effectiveness for the proposed indications.

{6}------------------------------------------------

- . Biocompatibility: Testing per ISO 10993 evaluated the relevant endpoints for an externally communicating device with limited contact with tissue: cytotoxicity, sensitization, intracutaneous irritation, acute systemic toxicity and material-mediated pyrogenicity. All results were acceptable.
- Benchtop tests: LOR channel sealing integrity, LOR channel sealing integrity per ISO 80369-. 7, Luer dimensional and functional attributes verification, probe penetration force, probe integrity, sensing mechanism, wings mechanism, particulate matter, corrosion resistance, device integrity, device operation time under load, torques on Front Luer and Housing interface point, Sensing mechanism consistency throughout shelf-life and LOR channel resistance.
- Electrical Safety and Electromagnetic Compatibility (EMC): The EpiFinder was determined to ● be in conformance with IEC 60601 and other applicable standards for electrical safety and EMC.
- . Software: Software verification and validation testing was conducted, and results were found acceptable for software release per IEC 62304:2006+AMD1:2015 and FDA's 2005 quidance document.
- . Animal Study: A study in pigs was conducted to evaluate the safety and effectiveness of using the EpiFinder device in epidural procedures in accordance with the proposed indications for use. The study was conducted in compliance with the OECD principles of Good Laboratory Practice (GLP) ENV/MC/CHEM (98)17 (except for the blood analysis). The study evaluated numerous test sites which were randomly divided into two groups: Group 1 (where the EpiFinder was used in conjunction with standard LOR technique) and Group 2 (where standard LOR technique alone was used). Needle advancement was halted when the epidural space was identified either by the EpiFinder's LEDs or by standard LOR technique, and the finding was confirmed using X-ray and contrast medium (if needed). Results demonstrated that the device is appropriate for its intended use (only one adverse event) and effective in providing a clear visual signal that the epidural needle had entered the epidural space.
- Human Factors Evaluation: Usability studies have been conducted with the EpiFinder per IEC . 62366-1:2015 and FDA's corresponding 2016 guidance document. The study was conducted with 16 anesthesiologists (physicians) and 10 student resident nurse anesthetists (sRNAs) to evaluate the safe use, any usability concerns, and clear readability of the IFU/labeling of the Epifinder. No use-related hazards were recorded. Three participants in each group experiences use problems, but these were deemed not to pose any additional risk. Additionally, users reported a high level of satisfaction with the device's design and ergonomic attributes.
- Clinical Evaluation: The EpiFinder was evaluated in a single arm, open label multicenter trial. The purpose of the trial was to assess the safety and performance of the EpiFinder in 31 adult subjects with clinical indication for a lumbar epidural steroid injection. The EpiFinder was found to be appropriate for use in human subjects. The performance of the device was also established, demonstrating that the device is capable of correctly identifying the epidural space during the injection procedure. In addition, the data from this trial demonstrate that the utilization of LOR technique with the EpiFinder is similar to the standard practice and that the device can be incorporated into clinical practice. All injections were performed on the lumbar region (21 injections in the L5-S1 interspace, 9 injections in the L4-L5 and one injection in L2-L3) while patients were in the prone position. 2 users conducted LOR technique with air as the medium while 1 user conducted it with saline as the medium.

{7}------------------------------------------------

## E. CONCLUSION

The EpiFinder is as safe and effective as the Epidrum predicate device (K093863). The EpiFinder has the same intended use and similar indications for use, and technological characteristics and principles of operation, as the predicate device. The minor technological differences between the EpiFinder and its predicate device raise no new issues of safety or effectiveness, and the reference device -Compass Epidural Assist (K112203) – further supports these elements of the EpiFinder technology. Performance data demonstrate that the minor technological differences do not adversely impact the subject device's performance as intended. Thus, the EpiFinder is substantially equivalent.
