No
The device description and performance studies focus on the physical mechanism of pulsed shortwave therapy and standard electrical/biocompatibility testing. There is no mention of AI, ML, image processing, or data-driven algorithms for diagnosis or treatment.
Yes
The device is described as an "adjunctive treatment of musculoskeletal pain" and a "pulsed shortwave therapy device" that produces a "therapeutic radiofrequency (RF) field". It also has clinical data showing significant pain reduction, all of which indicates it is a therapeutic device.
No
This device is described as an "adjunctive treatment of musculoskeletal pain" and a "pulsed shortwave therapy device," indicating its therapeutic rather than diagnostic function. Its clinical studies focus on pain reduction and safety, not on detecting medical conditions.
No
The device description explicitly states it is a "pulsed shortwave therapy device" with "circuitry," an "antenna," and a "battery power supply," indicating it is a hardware device that generates an RF field. The performance studies also include testing related to electrical safety, electromagnetic safety, and biocompatibility, which are characteristic of hardware devices.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "Adjunctive treatment of musculoskeletal pain." This describes a therapeutic purpose, not a diagnostic one. IVDs are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description details a pulsed shortwave therapy device that applies RF energy to target tissue. This is a physical therapy modality, not a device that analyzes biological samples.
- Lack of IVD Characteristics: The description does not mention any components or processes related to collecting, preparing, or analyzing biological specimens (like blood, urine, tissue, etc.).
- Performance Studies: The performance studies focus on electrical safety, electromagnetic safety, biocompatibility, and clinical trials evaluating pain reduction. These are typical studies for therapeutic devices, not IVDs which would focus on analytical performance (sensitivity, specificity, accuracy, etc.).
Therefore, the ActiPatch device, as described, is a therapeutic device and not an In Vitro Diagnostic.

Device Description
The ActiPatch® device is a pulsed shortwave therapy device. The circuitry consists of low voltage (3 V) digital/analog electronics that control all timing functions to produce the therapeutic radiofrequency (RF) field, where the antenna is placed directly above the therapeutic site. This closed loop system of the antenna, low energy signal generator circuit, and battery power supply, transfers the RF energy to the target tissue as a localized therapy with no far field effects.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
- A randomized, controlled trial on chronic cervical osteoarthritis (neck pain): This was a randomized, active-treatment controlled study to evaluate the safety and effectiveness of the ActiPatch medical device to reduce the pain level of patients diagnosed with cervical osteoarthritis. The active-treatment control was an NSAID of the Cox-2inhibitor family. There were 200 intent-to-treat patients, out of which 197 completed the four-week study. There were 142 women (71%) and 58 (29%) men in the study, with an average age of 45 years. The primary endpoint for efficacy was reduction in pain (VAS score) while at rest and being active, over four weeks, when compared to the beginning of the study. The results indicate that ActiPatch significantly reduced pain (measured by VAS pain) associated with COA in the device treatment group, and that the treatment differences between device-treatment and NSAID-treatment groups was significant (p

12.Substantial Equivalence:
ActiPatch has the same intended use as the predicate device, i.e., the application of electromagnetic energy to non-thermally treat pain. The current ActiPatch's technological features are identical to those of the predicate ActiPatch device in K152432 (Table 2). No device modifications have been made to the current ActiPatch, when compared to the predicate ActiPatch device.
The predicate device is indicated for adjunctive treatment of musculoskeletal pain related to: 1) Osteoarthritis of the knee; and 2) Plantar fasciitis of the heel (K152432). The performance data submitted in the premarket notification, including the electrical safety, electromagnetic safety, biocompatibility, and clinical data described in Section 13 below, show that there is no difference in technology between the subject and predicate device, and that the subject ActiPatch is at least as safe and effective as the predicate ActiPatch.

13.Testing
Non-Clinical/Performance Data:
Electrical safety, electromagnetic safety, biocompatibility testing, and testing in accordance with the special controls of the October 13, 2015 Final Reclassification Order for Nonthermal Shortwave Therapy devices was performed for the ActiPatch.
The ActiPatch was tested for conformity to the following standards and was determined to conform to these standards:
- General Safety and Requirements - Medical Equipment- IEC/EN 60601-1-2
- General Safety and Requirements Medical Equipment- EN ● 60601-1:2006
Biocompatibility testing was conducted for the ActiPatch. The skin sensitization test performed in accordance with ISO 10993-10:2010 showed no evidence of an ActiPatch extract causing skin sensitization in guinea pigs. The skin irritation test conducted in accordance with ISO 10993-10:2010 demonstrated that gauze material saturated with extract from the ActiPatch showed no evidence of causing skin irritation in New Zealand white rabbits. The cytotoxicity test performed in accordance with ISO 10993-5:2009 showed that no observable in vitro cytotoxicity in L-

929 mouse fibroblast cells that were placed in contact with an extract prepared from ActiPatch.
The testing that was conducted in accordance with the special controls of the October 13, 2015 Final Reclassification Order demonstrated that the ActiPatch performs as intended under anticipated conditions of use. The testing determined and considered the peak output power; the pulse width; the pulse frequency; the duty cycle; the average measured output powered into the RF antenna/applicator; the specific absorption rates in a saline gel test load; the characterization of the electrical and magnetic fields in saline gel test load for each RF antenna and prescribed RF antenna orientation/position; and the characterization of the deposited energy density in saline gel test load.
Clinical Data:
The clinical data in this 510(k) includes results from three IRB approved, randomized, controlled studies. Additionally, usability testing was conducted to support the OTC use of the device.
- A randomized, controlled trial on chronic cervical osteoarthritis (neck pain): This was a randomized, active-treatment controlled study to evaluate the safety and effectiveness of the ActiPatch medical device to reduce the pain level of patients diagnosed with cervical osteoarthritis. The active-treatment control was an NSAID of the Cox-2inhibitor family. There were 200 intent-to-treat patients, out of which 197 completed the four-week study.

The primary endpoint for efficacy was reduction in pain (VAS score) while at rest and being active, over four weeks, when compared to the beginning of the study. The results indicate that ActiPatch significantly reduced pain (measured by VAS pain) associated with COA in the device treatment group, and that the treatment differences between device-treatment and NSAID-treatment groups was significant (p
