The summary describes a standard electro-mechanical pump system for negative pressure wound therapy and does not mention any AI or ML components or capabilities.
Yes
The device is indicated for promoting wound healing and is described as a Negative Pressure Wound Therapy (NPWT) System, which is a recognized therapeutic intervention.
No
The device is a negative pressure wound therapy system, which is a therapeutic device designed to promote wound healing by removing exudate and infectious materials. It does not analyze patient data or provide a diagnosis.
No
The device description explicitly states it is an "electro-mechanical pump system" and includes physical components like a pump, Y-connector, dressings, and fixation strips. This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device that applies negative pressure to a wound to promote healing by removing exudate and infectious materials. This is a therapeutic intervention applied directly to the body, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details a pump system, tubing, and dressings designed to create and maintain negative pressure on a wound. This aligns with a therapeutic device, not a diagnostic one.
- Lack of IVD Characteristics: The description does not mention any components or processes related to analyzing biological samples (like blood, urine, tissue, etc.) to provide diagnostic information. There's no mention of reagents, assays, or any form of in vitro testing.
Therefore, the PICO 7Y Single Use Negative Pressure Wound Therapy System is a therapeutic medical device, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Tests (Bench)
- Wound model testing was conducted on the PICO 7Y system and compatible dressings from the PICO range (10x20cm and 25x25cm dressings) at low and moderate flow rate in vertical and horizontal positions. The results showed that all dressings managed fluid (0.6 g/cm²/24 hours for low, 1.1 g/cm²/24 hours for moderate) for a simulated wound of 25% of the dressing absorbent pad area. The dressings maintained negative pressure within -60 mmHg to -100 mmHg for a minimum of 95% of the test time.
- Wound model testing was conducted on the PICO 7Y dressings in the absence of negative pressure in vertical and horizontal positions. The results showed that all dressings in a vertical position managed fluid (0.5 g/cm²/24hrs and 0.3g/cm²/24hrs) for a simulated wound of 25% of the dressing absorbent pad area.
- Functionality testing was conducted on the PICO 7Y device to demonstrate handling small (50ml) and large (600ml) simulated wounds simultaneously. The results (using one 50ml and two 300ml canisters) showed pump pressure limits between -100 to -60mmHg, a cycle of >=10mmHg, and time to reach target negative pressure less than 100seconds.
- The ability of the PICO 7Y device to deliver negative pressure whilst in a battery low state was assessed. Test results showed continued delivery of negative pressure.
- Check dressing indicator performance testing was conducted on the PICO 7Y device. The results showed the indicator successfully activated after 24 hours use while maintaining negative pressure. After resetting, the second occurrence activated after a minimum of 23 hours 45 minutes and a maximum of 24 hours 10 minutes.
- Performance testing was conducted to demonstrate the dressing's ability to manage exudate when NPWT is lost due to a blocked port. Test results showed successful exudate management during and after loss of negative pressure for the 7-day service life.
- Performance bench testing was conducted to confirm that when one dressing soft port is blocked, pressure is maintained on the non-blocked dressing. The results demonstrated acceptable levels of negative pressure to the non-blocked dressing.
- Air leak testing was conducted on PICO 7Y device by introducing deliberate air leaks. Test results showed that the air leak indicator activated at specified time points, representing initial application to achieve therapeutic negative pressure range (-60mmHg to -100mmHg, target -80mmHg) and maintenance of this range.

- . Chronic
- . Acute
5
- Traumatic .
- Subacute and dehisced wounds ●
- Partial-thickness burns .
- Ulcers (such as diabetic or pressure) ●
- Flaps and grafts ●
- . Closed Surgical incisions
PICO Systems are suitable for use both in a hospital and homecare setting.
Comparison between subject device and predicate device
The main differences between the cleared PICO 7 System (K180698) and the subject device are as follows:
-
- Introduction of a Y connector to the existing PICO 7 pump device (K180698) allowing delivery of negative pressure to two wounds simultaneously. The O-ring component within the pump device has been changed to enable securing the Y Connector within the pump device casing.
-
- Extension of the soft port connected to the large multisite dressing kit for use with PICO 7Y Single Use Negative Pressure Wound Therapy System. The dressing components are identical to existing large multisite dressings (20 x 25cm or 7.9 x 9.8 inches); however the soft port has been extended for user convenience so that when using the device on two wounds, use of the extension tubing is not necessary.
- Introduction of a new packaging configuration incorporating dimensional 3. changes to accommodate for additional PVC tubing, the instructions for use being presented as booklets, and the "book" style carton used in the predicate device being replaced with a tuck end carton.
-
- Replacement of the 'Dressing Full' indicator with the 'Check Dressing' indicator to remind the user to check their dressing every 24hours.
6
-
- Corresponding changes to the software to accommodate the use of the system on two wounds and replacement of the 'Dressing Full' indicator with 'Check Dressing' indicator.
- Replacement of Alkaline batteries with Lithium batteries which are 6. identical to those which were used in a previously cleared version of PICO Single Use Negative Pressure Wound Therapy System (K163387).
- Corresponding changes to the instructions for use to reflect the design 7. changes made to the subject device.
The following testing has been completed on the subject device:
Non-Clinical Tests (Bench)
-
. Wound model testing was conducted on the PICO 7Y system and compatible dressings from the PICO range (10x20cm and 25x25cm dressings) at low and moderate flow rate in vertical and horizontal positions.
The results of the tests showed that all of the dressings managed fluid at a flow rate modelling a low (0.6 g/cm²/24 hours) and a moderately exuding wound (1.1 g/cm²/24 hours) respectively for a simulated wound of 25% of the dressing absorbent pad area. The results also showed that the dressings maintained negative pressure within the test requirements of -60 mmHg to -100 mmHg for a minimum of 95% of the test time at the simulated wound base throughout the test. Based on the results of the tests it can be concluded that the PICO 7Y device and accessories can be used for their intended purposes. -
Wound model testing was conducted on the PICO 7Y dressings in the . absence of negative pressure in vertical and horizontal positions. The results of the tests showed that all of the dressings in a vertical position managed fluid at a flow rate modelling moderate and low exuding wounds
7
with no NPWT (0.5 g/cm²/24hrs and 0.3g/cm²/24hrs) for a simulated wound of 25% of the dressing absorbent pad area. Based on the results it can be concluded that the PICO 7Y dressings (large multisite) can handle fluid without the presence of negative pressure.
- Functionality testing was conducted on the PICO 7Y device to ● demonstrate that PICO 7Y pump unit has been adequately designed to handle small (minimum total 50ml volume) and large (maximum total 600ml volume) simulated wounds simultaneously. The results of the tests (using one canister of 50ml and two 300ml canisters respectively to simulate small and large wounds) showed that the pump pressure limits were recorded between -100 to -60mmHg and had a cycle of ≥10mmHg and the time taken to reach the target negative pressure was less than 100seconds. This demonstrated the pump can be used for its intended purpose.
- The ability of the PICO 7Y device to deliver negative pressure whilst in a . battery low state was assessed. Test results showed that the PICO 7Y device can continue to deliver negative pressure when the device is in a battery low state demonstrating that the pump can be used for its intended purpose.
- Check dressing indicator performance testing was conducted on the PICO . 7Y device. The results of the tests showed that the check dressing indicator successfully activated after 24 hours use, while maintaining negative pressure.
After resetting, per the Instructions for Use and Intended Use, the second occurrence of the check dressing indicator activated after a minimum of 23 hours and 45 minutes and a maximum of 24 hours and 10minutes. Based on the test results, it can be concluded that the PICO 7Y devices can be used for their intended purposes.
8
- Performance testing was conducted on the PICO 7Y device to . demonstrate that the dressing is able to manage exudate in a scenario when NPWT is lost after the port becomes blocked, thus mitigating risk of maceration. Test results show that the system when tested under the maximum clinically acceptable flow rate successfully manages exudate during the delivery of negative pressure and following the loss of negative pressure until the 7 day service life has been achieved. As such the design of the dressing provides for inherent safety and acts as an effective primary mitigation for the risk that a dressing is left in place after a port blockage scenario has occurred.
- Performance bench testing was conducted to confirm system performance ● and demonstrate that when one dressing soft port is blocked, pressure is maintained within the specified range on the non-blocked dressing. The results demonstrate that when one dressing soft port is blocked due to oversaturation of the dressing, the PICO 7Y device is still able to deliver acceptable levels of negative pressure to the non-blocked dressing.
- Air leak testing was conducted on PICO 7Y device by introducing . deliberate air leaks into the system to show that when the system has a high leak rate, the leak indicators activate to alert the user to inspect the dressing application and address the point of air ingress/ air leak. Test results showed that air leak indicator was activated at specified time points in line with the test requirements representing the initial application of the system to achieve the therapeutic negative pressure range of -60mmHg to -100mmHg (target -80mmHg); and maintenance of the therapeutic pressure range.
Based on the test results, it can be concluded that the PICO 7Y devices can be used for their intended purposes.

Shelf Life
The PICO 7Y system has been evaluated using real time and accelerating ageing challenge conditions and a combination of simulated wound model testing as well as specification testing to demonstrate system functionality over the duration of the shelf life.
Test results showed that all dressings managed fluid at a flow rate modelling a low (0.6 g/cm²/24 hours) and a moderately exuding wound (1.1 g/cm²/24 hours) respectively for a simulated wound of 25% of the dressing absorbent pad area. The results also showed that the dressings maintained negative pressure within
10
the test requirements of -60 mmHg to -100 mmHg for a minimum of 95% of the test time at the simulated wound base throughout the test without any pressure readings being lower than -235mmHg. Furthermore, all specification test results complied with the acceptance criteria as defined within the test requirements. The results of all tests showed that the subject device was able to maintain its functionality over the duration of the ageing study and that a shelf life of 24 months (2 years) can be applied to the PICO 7Y system. Therefore, it can be concluded that the PICO 7Y device and accessories can be used for their intended purposes.
Human Factors/Usability Engineering Testing
A summative study was carried out in the US. Instructions for Use (IFU) validations were also carried out to demonstrate that the intended users (Lay Users, Healthcare Professionals) can follow the instructions as intended and understand information for safety from the instructions for use. The summative study activities did not result in any patterns of use errors that when assessed resulted in an unacceptable residual risk. PICO 7Y system has appropriate design mitigations in order to prevent and control harm occurring due to use error. It was therefore concluded that PICO 7Y system is safe and effective for use by the intended users, for the described uses in the expected environments.
Conclusions
In establishing substantial equivalence to the predicate device, Smith & Nephew Medical Ltd evaluated the indications for use, materials, technology, product specifications and energy requirements of the device. Performance testing, service life testing and electrical safety testing has been completed to demonstrate that the PICO 7Y Single Use Negative Pressure Wound Therapy System is substantially equivalent to predicate device for the intended use.
