The summary describes a standard negative pressure wound therapy system with a pump and dressing. There is no mention of AI, ML, image processing, or any other technology that would suggest the use of AI/ML. The performance studies focus on bench testing and clinical outcomes related to wound healing and adverse events, not on the performance of an AI/ML algorithm.
Yes
The device is indicated for promoting wound healing and managing various wound types, including chronic, acute, and ulcers, by removing exudate and infectious materials, which are therapeutic actions.
No
The device description and intended use clearly state that it is a suction device (Negative Pressure Wound Therapy system) designed to promote wound healing by removing exudate and infectious materials. It does not mention any function for diagnosing conditions or diseases.
No
The device description explicitly states it is an "electro-mechanical pump system connected through a flexible tube to a super-absorbent, gentle adhesive dressing," indicating it includes hardware components beyond just software.
Based on the provided information, the PICO 14 Single Use Negative Pressure Wound Therapy System is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use clearly states that the device is a "suction device (NPWT)" used to promote wound healing by removing exudate and infectious materials. This is a therapeutic function applied directly to the patient's body.
- Device Description: The description details a pump system, tubing, and a dressing. These are components of a therapeutic device, not a device used to examine specimens from the human body.
- Lack of IVD Characteristics: There is no mention of the device being used to test or analyze biological samples (blood, urine, tissue, etc.) to provide information about a patient's health status, diagnose, monitor, or screen for diseases.
IVD devices are used in vitro (outside the body) to examine specimens. The PICO 14 system is used in vivo (on the body) for therapeutic purposes.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Tests (Bench):
The PICO 14 Single Use Negative Pressure Wound Therapy System delivers the same nominal negative pressure of -80mmHg and the same pressure profile as the PICO 7 System. The only functional changes are to increase the use time from 7 to 14 days, two repetitions of the dynamic duty cycle used in PICO 7 to maximize power use of 14 days instead of 7 days and changes to the maximum Initial Pump Down (IPD) and Maintenance Pump Down (MPD) times.
- 14 Day System Use: Bench tests successfully completed, representing worst case scenarios. The wound model tests demonstrate that, in a clinically representative scenario, the PICO 14 system can manage wound exudate and deliver Negative Pressure over 14 days.
- Deep Wound Model Testing: Bench tests successfully completed, representing worst case scenarios. The wound model tests demonstrate that, in a clinically representative scenario, the PICO 14 system can manage wounds up to 4.5cm deep.
The testing utilized PICO pumps from the predicate submission; as discussed throughout this 510(k), the NPWT delivery profile is unchanged between the subject and predicate devices, hence the data from the predicate system as applicable to the subject system.
Clinical Evidence Summary:
- Clinical evidence was provided to support the use of PICO 14 in wounds with depths up to 4.5 cm.
- Study Population: All patients at two community care access centers, who were admitted and received care for a chronic wound (pressure ulcer (PU), diabetic foot ulcer (DFU), venous leg ulcer (VLU), surgical ulcer (open incision)) from March 31, 2016 until March 31, 2018.
- Sample Size: 3,159 patients followed from admission to healing. 917 patients used the PICO device. 409 of those patients had wound depths greater than 2 cm (233 DFUs, 18 PUs, 147 dehisced surgical wounds, and 11 VLUs).
- Key Results:
- Time to healing, number and duration of dressing changes, and adverse events were recorded.
- The adverse event rate in the PICO groups (depth 2cm 2.5%) was lower than the non-PICO group (6.6%).
- There were no PICO device related adverse events in the > 2cm group.
- Data were provided on the 32 of the 917 (2.8%) patients that discontinued PICO. 11 of those patients discontinued due to infection (1) or drainage (10). For the drainage, the clinician decided the exudate rate had increased beyond the indicated low to moderate exudate rate.
- The data provided demonstrates safety of the device for wounds with depths up to 4.5 cm.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Adverse event rate:
- PICO groups (depth 2cm): 2.5%
- Non-PICO group: 6.6%
Discontinuation rate for PICO: 2.8% (32 out of 917 patients)

Comparison of Subject and Predicate Devices
| Comparison Between PICO 7 (Predicate Device) and PICO 14 (Subject Device) | |
|---|---|
| Software | The only changes to the software are minor convenience updates to the maximum pump down times and to allow for use over a 14 day period instead of 7 days (predicate device). There are no changes to the function of the system with respect to the delivery of NPWT, |
| Packaging format | The packaging format been modified to provide a more simple manufacturing process. The materials used in the packaging are unchanged however the IFU will now be in an A4 book format and the carton will be a single box with an insert rather than the book format. |
| Indications for Use statement | PICO 7 and PICO 14 are identical. |
| Instructions for use | The Instructions for Use are largely the same as the predicate system. The main changes are to provide clarity with respect to wound depth. The updated wording is clear that PICO 14 is suitable for use on wounds up to 4.5cm deep. Wounds greater than 0.5cm (1/4 in.) in depth are likely to require a foam or gauze negative pressure wound therapy filler to ensure adequate treatment of all the wound surface. Wounds treated with the PICO 14 system should generally be no more than 4.5cm (1 $1\frac{3}{4}$ in.) in depth and must not contain exposed arteries, veins, nerves or organs. |
| Technological principal for delivering the negative pressure wound therapy | PICO 7 and PICO 14 are identical |
| PICO Pump | Embossing and symbol changes to change from 7 day use to 14 day use and change to icon bar color (from gray to black). |
| Physical components of the pumps, dressings and tubing | PICO 7 and PICO 14 are identical |
| Batteries | While an additional set of batteries are now provided, |
| The predicate system could require a battery change, | |
| which was already communicated to the user. Two sets | |
| of batteries will be provided in the case that the user | |
| needs to change the batteries (the predicate device | |
| provides one set of batteries). One of the battery sets | |
| will be provided sterile within the primary pump tray | |
| packaging (identical to the predicate device) and one set | |
| is provided non-sterile as an extra set. | |
| System-use time | The system use time has changed from 7 days |
| (predicate device) to 14 days (subject device). | |
| User interface | PICO 14 remains similar, with only minor changes to the |
| product appearance and packaging | |
| Electrical Safety and | |
| Electromagnetic | |
| Compatibility (EMC) | PICO 7 and PICO 14 are identical |
6
These minor changes discussed above are not considered to change the safety profile of the system, nor do they raise any new questions of safety or efficacy.
The changes do not reflect any new user tasks, nor do they impact any of the critical tasks associated with the use of PICO and the users are not expected to complete any new tasks.
Given the identical nature of the physical aspects of the predicate system and PICO 14, much of the data to support the product is the same as the predicate data.

Non-Clinical Tests (Bench)
The PICO 14 Single Use Negative Pressure Wound Therapy System delivers the same nominal negative pressure of -80mmHg and the same pressure profile as the PICO 7 System. The only functional changes are to increase the use time from 7 to 14 days, two repetitions of the dynamic duty cycle used in PICO 7 to maximize power use of 14 days instead of 7 days and changes to the maximum Initial Pump Down (IPD) and Maintenance Pump Down (MPD) times.
Since the system continues to act exactly as with the PICO 7 system, the bench testing provided is to demonstrate two aspects:
-
- The system can function for 14 days without failure
-
- The system continues to function when used on wounds up to 4.5cm deep
14 Day System Use
Bench tests have successfully been completed and represent worst case scenarios. The wound model tests demonstrate that, in a clinically representative scenario, the PICO 14 system can manage wound exudate and deliver Negative Pressure over 14 days.
Deep Wound Model Testing
Bench tests have successfully been completed and represent worst case scenarios. The wound model tests demonstrate that, in a clinically representative scenario, the PICO 14 system can manage wounds up to 4.5cm deep.
The testing utilized PICO pumps from the predicate submission; as discussed throughout this 510(k), the NPWT delivery profile is unchanged between the subject and predicate devices, hence the data from the predicate system as applicable to the subject system.
Clinical Evidence Summary
Clinical evidence was provided to support the use of PICO 14 in wounds with depths up to 4.5 cm. The study population included all patients at two community care access centers, who were admitted and received care for a chronic wound (pressure ulcer (PU), diabetic foot ulcer (DFU), venous leg ulcer (VLU), surgical ulcer (open incision)) from March 31, 2016 until March 31, 2018. 3,159 patients were followed from admission to healing. 917 patients used the PICO device and 409 of those patients had wound depths greater than 2 cm in which 233 were DFUs, 18 were PUs, 147 were dehisced surgical wounds, and 11 were VLUs.

to healing, number and duration of dressing changes, and adverse events were recorded.
The adverse event rate in the PICO groups (depth 2cm 2.5%) was lower than the non-PICO group (6.6%). There were no PICO device related adverse events in the > 2cm group. Data were provided on the 32 of the 917 (2.8%) patients that discontinued PICO. 11 of those patients discontinued due to infection (1) or drainage (10) and for the drainage, the clinician decided the exudate rate had increased beyond the indicated low to moderate exudate rate. The data provided demonstrates safety of the device for wounds with depths up to 4.5 cm.
Biocompatibility, Sterilization and Electrical Testing
PICO 14 Single Use Negative Pressure Wound Therapy System has been evaluated according to the Biological Evaluation of Medical Devices Standard BS EN ISO 10993, with particular reference to Part 1 (2009): Evaluation and testing within a risk management process and FDA guidance 'Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". PICO 14 Single Use NPWT Use System uses the same dressings with soft port as the predicate PICO Single Use NPWT System; the materials are identical and therefore no new biocompatibility data are required. Additionally, the exterior pump components remain identical to the predicate device already cleared by the FDA.
The PICO 14 Single Use Negative Pressure Wound Therapy System has the same electrical characteristics as the predicate system (K180698), with the only changes being a software update. The software changes will not impact on the electrical safety of the system.
Conclusions
In establishing substantial equivalence to the predicate devices, Smith & Nephew Medical Ltd evaluated the indications for use, materials, technology, product specifications and energy requirements of the device. It was confirmed that the PICO 14 Single Use Negative Pressure Wound Therapy System continues to use the same materials as the predicate system and provides the same user interface.
Performance testing has been completed to demonstrate that the PICO 14 Single Use Negative Pressure Wound Therapy System is substantially equivalent to the predicate for the intended use.
