The ELEXIR 2.0 is indicated for the acute treatment of migraine (Acute mode, frequency 100 Hz) and the prophylactic treatment of episodic migraine (Prevention mode, frequency 60 Hz) in patients 18 years of age or older.
The ELEXIR 2.0 is a transcutaneous electrical nerve stimulator (TENS) that is applied to the forehead using a self-adhesive electrode positioned over the upper branches of the trigeminal nerve bilaterally. It is intended to stimulate the upper branches of the trigeminal nerve in order to reduce the frequency of migraine attack. The ELEXIR 2.0 is indicated for the acute treatment of migraine and the prophylactic treatment of episodic migraine by applying 100 Hz (Acute mode) and 60 Hz (Prevention mode), low-frequency stimulation to the forehead area percutaneously to the trigeminal nerve.
The provided text is a 510(k) summary for the ELEXIR 2.0 (ALLIVE3) device, a transcranial electrical nerve stimulator for headache treatment. The document focuses on demonstrating substantial equivalence to a predicate device (ALLIVE2 (ELEXIR)) rather than presenting a study of the device's clinical performance against specific acceptance criteria.
Therefore, the requested information regarding "acceptance criteria" for device performance, a "study that proves the device meets the acceptance criteria," "sample size," "data provenance," "number of experts," "adjudication method," "MRMC comparative effectiveness study," "standalone performance," "type of ground truth," and "training set details" cannot be extracted from this document, as it describes non-clinical testing for safety and electrical performance, and equivalence to a predicate, not clinical efficacy or diagnostic accuracy.
The document lists various non-clinical tests performed, such as:
- Biocompatibility tests: Cytotoxicity (ISO 10993-5:2009), Sensitization (ISO 10993-10:2010), and Intracutaneous Reactivity Test (ISO 10993-10:2010).
- Electrical Safety and EMC tests: IEC 60601-1:2005+A1:2012, IEC 60601-1-2:2014, IEC 60601-1-11:2015, and IEC 60601-2-10:2012/A1:2016.
- Performance Tests: IEC 60601-2-10:2012/A1:2016, Technical Test (IEC 60601-2-10:2012/A1:2016), Performance Test under wireless communication (Manufacturer's own standards), and Lifetime study (Manufacturer's own standards).
- Usability V&V: IEC 60601-1-6:2010/A1:2013 and IEC 62366-1:2015.
- Software Test: IEC 62304:2006/A1:2015.
These tests are primarily aimed at establishing the safety and fundamental performance characteristics to claim substantial equivalence, rather than demonstrating specific clinical effectiveness against quantified criteria. The document states, "the safety and performance test reports support the safety and effectiveness of the subject device," which is a general conclusion based on these non-clinical evaluations and comparison to the predicate.
Without a clinical study section, the specific details for clinical performance criteria and their evaluation are not available in this 510(k) summary.
§ 882.5891 Transcutaneous electrical nerve stimulator to treat headache.
(a)
Identification. A transcutaneous electrical nerve stimulator to treat headache is a device used to apply an electrical current to a patient's cranium through electrodes placed on the skin.(b)
Classification. Class II (special controls). The special controls for this device are:(1) The patient-contacting components of the device must be demonstrated to be biocompatible.
(2) Appropriate analysis/testing must validate electromagnetic compatibility and electrical, mechanical, and thermal safety.
(3) The technical parameters of the device, including waveform, output modes, maximum output voltage and current (with 500, 2,000, and 10,000 ohm loads), pulse duration, frequency, net charge (µC) per pulse, maximum phase charge at 500 ohms, maximum current density (mA/cm
2 , r.m.s.), maximum average current (mA), maximum average power density (W/cm2 ), and the type of impedance monitoring system must be fully characterized.(4) Electrical performance, adhesive integrity, shelf life, reusability, and current distribution testing of the electrodes must be conducted.
(5) Appropriate software verification, validation, and hazard analysis must be performed.
(6) Clinical performance data must demonstrate that the device is safe and effective as a treatment for headache in the indicated patient population.
(7) Labeling must include the following:
(i) Appropriate contraindications such as not for use in subjects with an implanted metallic or electronic device in the head, a cardiac pacemaker, or an implanted or wearable defibrillator.
(ii) Appropriate warnings such as not to apply the device on the neck or chest, not to use the device in the presence of electronic monitoring equipment, not to use in the bath or shower, not to use while sleeping, not to use while driving, not to use while operating machinery.
(iii) Appropriate precautions such as the long-term effects of chronic use of the device are unknown.
(iv) A summary of the expected risks and benefits of using the device.
(v) A summary of the clinical performance data, including information on the patient population for which the device has and has not been demonstrated to be effective, and any adverse events and complications.
(vi) Information on how the device operates and the typical sensations experienced during treatment.
(vii) A detailed summary of the device technical parameters.
(viii) An expiration date/shelf life for the electrodes and the number of times they can be reused.
(ix) Disposal instructions.
