No
The description focuses on the mechanical and electronic functions of a negative pressure wound therapy system, with no mention of AI or ML capabilities for data analysis, decision-making, or adaptive therapy. The testing described is standard for medical devices and does not indicate AI/ML development or validation.
Yes
The device is described as a "Negative Pressure Wound Therapy System" that "may promote wound healing by removing low to moderate levels [...] of exudate and infectious materials" from various wound types. This directly aligns with the definition of a therapeutic device, which is designed to treat or alleviate a medical condition.
No
The device is a negative pressure wound therapy system, which is a therapeutic device that promotes wound healing by removing exudate and infectious materials. It does not diagnose conditions.
No
The device description explicitly lists hardware components such as a battery-operated vacuum pump, a flexible exudate canister, and a sterile wound interface kit. The performance studies also include testing related to electrical safety, electromagnetic compatibility, biocompatibility, sterility, and mechanical performance, all of which are associated with hardware.
Based on the provided information, the myNeWT system is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the system is for applying negative pressure to wounds to promote healing by removing exudate and infectious materials. This is a therapeutic intervention applied directly to the patient's body.
- Device Description: The description details a pump, canister, tubing, and wound interface kit used to create and manage negative pressure on a wound. This is consistent with a medical device used for treatment, not for analyzing samples outside the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening.
IVD devices are specifically designed to perform tests on samples taken from the body. The myNeWT system is a therapeutic device used to treat wounds directly on the patient.

PREDICATE DEVICE
Substantial Equivalent claimed to:
PICO Single Use Negative Pressure Wound Therapy system, Smith and Nephew (510k number K112127 – Primary Predicate), in the basis that both systems are a portable, body worn, disposable Single Use system for patients who have hard to heal wounds. Therapy is accomplished by the electronically controlled pump unit, operating on primary batteries only, and delivering a continuous negative pressure to the wound surface, which draws the exudate into a containment system, creating an environment that promotes wound healing via the removal of low to moderate amounts of exudate and infectious materials from the wound. The device is programmed to run for 7 days after the batteries are inserted, after which the device will not operate and will need to be replaced. Indications for use are similar.

V.A.C Via Negative Pressure Wound Therapy system, KCI USA Inc (510k number K132741 - Additional Predicate), in the basis that both systems are a portable, body worn, Single Use system for patients who have hard to heal wounds. Therapy is accomplished by the electronically controlled pump unit, operating on rechargeable batteries, delivering a negative pressure to the wound surface, which draws the exudate into a containment system, creating an environment that promotes wound healing via the removal of low to moderate amounts of exudate and infectious materials from the wound. The negative pressure level may be varied within set parameters. The device is programmed to run for 7 days, after which the device will not operate and will need to be replaced. Indications for use are similar.
DEVICE DESCRIPTION
The myNeWT Negative Pressure Wound Therapy System is a portable, body worn, Single Use system for patients who have hard to heal wounds. Therapy is accomplished by the electronically controlled pump unit delivering a continuous negative pressure at -80 mmHg ±20mmHg to the wound surface, which draws the exudate into a flexible exudate canister, creating an environment that promotes wound healing via the removal of low to moderate amounts ( 37.5 ml/day) exudate flow rates. ●
The Indications for Use and Contraindications are similar to the predicate devices, and the slight textural variances do not alter the intended therapeutic use of the device nor do they affect the safety and effectiveness of the device relative to the predicates. Both the subject and the predicate devices have the same intended use for patients who would benefit from Negative Pressure Wound Therapy as it may promote wound healing by removing low to moderate level of exudate and infectious materials.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICES
The myNeWT System is similar to the predicate devices listed above in function and operating principles to achieve similar results, however the myNeWT System possesses a combination of features that each of the predicate devices incorporate individually. The myNeWT System combines these features to offer greater flexibility in portability, whilst retaining the same clinical benefits.
The subject and predicate devices are based on the following same technological elements:
- A battery operated pneumatic pump to deliver a controlled level of negative . pressure (vacuum) to the wound bed of a hard to heal wound
- A controlled level of negative pressure (vacuum) of -60mmHz to -100mmHg ● nominal
- The pump is software controlled
- A collection device or canister to contain the exudate ●
- A wound interface to connect the negative pressure to the wound ●
- . A wound dressing cover with medical adhesive (in the myNeWT System, this is supplied by the Healthcare Professional setting up the device from existing wound care products)
- . Tubing and connection systems to connect the wound to the vacuum source.
- The system operates for 7 days of therapy only.
- The system is disposable after 7 days of use. ●
The following technological differences exist between the subject and predicate devices:
- The myNeWT System uses a flexible canister to collect the exudate, the PICO ● uses a flexible canister combined with the wound interface and the VAC Via uses a rigid canister.
- . The myNeWT System allows the Healthcare Professional to select the wound dressing components from a range to cleared medical wound care items, allowing the Healthcare Professional to be able to match the appropriate dressing components to the wound size, shape and location. The predicate devices supply the wound dressing covers, often requiring a range of kits to suit varving wound sizes or shapes, but allows the Healthcare Professional to supply any other wound dressing components required (gauze, skin preps, saline solution etc ).
- The myNeWT System and VAC Via have an audible and visual alert to notify the user of system status, the PICO system only has visual alerts.
The myNeWT System provides the safety features required to protect the patient, including high vacuum alert, leak alert, battery status alert, therapy day of use alert and pump error alert.

Distribution Testing
The final packed myNeWT kit was subjected to distribution testing in accordance with ISTA Procedure 2A (2011).
Animal Studies
No animal testing was performed on the myNeWT System.
Clinical Studies
Clinical testing was not required to demonstrate the substantial equivalence of the myNeWT System to the predicate devices.
EQUIVALENCY CONCLUSION
The myNeWT System passed all the verification and validation testing, and no new issues of safety or effectiveness have been raised against the predicate devices.
Based on the information provided in the accompanying 510(k), Stortford Medical LLC concludes that the myNeWT System is substantially equivalent to the predicate devices listed above.
