InMode Plus System
The InMode PLUS System with the PLUS/PLUS90 Hand pieces is indicated for the temporary relief of minor muscle aches and pain, temporary relief of muscle spasm, and temporary improvement of local blood circulation.
The InMode PLUS System delivers RF energy to gradually heat the skin and subcutaneous tissue. The RF power levels used by the device can be adjusted from 10 to 50 Watts and the maximum skin temperature cutoff can be adjusted from 35℃ to a maximum of 42℃. The hand pieces are operated while continuously moving them over the treatment area. This ensures uniform and safe heating of the entire trea.
Each InMode PLUS hand piece is comprised of the hand piece handle, a cable 250 cm long, and a connector, which connects to the rear connector of the InMode PLUS System.
Two InMode PLUS hand pieces are available:
- InMode PLUS hand piece (held perpendicular to the treatment area)
- InMode PLUS90 hand piece (held parallel to the treatment area)
Following are the InMode PLUS System specifications: Maximal RF Output Power: 50 Watt RF Output Frequency: 1.0[MHz] ± 2% Maximum Temperature (skin surface): 42°C ± 2°C
The provided document is a 510(k) Premarket Notification from the FDA for the InMode PLUS System. It details the device's indications for use, technical specifications, and the basis for its substantial equivalence to a predicate device.
However, it does not contain information about a clinical study involving human patients, human readers, or AI assistance for diagnostic purposes. The document explicitly states "Clinical Performance Data: Not Applicable."
The performance data presented is based on bench testing and ex-vivo tissue studies, not in-vivo human studies. Therefore, I cannot provide information on acceptance criteria related to human performance, multi-reader multi-case studies, or AI-assisted diagnoses.
The document discusses the following performance tests relevant to the device's substantial equivalence for its stated indications (temporary relief of minor muscle aches and pain, temporary relief of muscle spasm, and temporary improvement of local blood circulation):
1. Acceptance Criteria and Device Performance (Bench and Ex-vivo Studies Only):
| Acceptance Criteria Category | Specific Criteria (Implicit from study design) | Reported Device Performance |
