Intended Use

PICO 7 Single Use Negative Pressure Wound Therapy System, PICO 7Y Single Use Negative Pressure Wound Therapy System, PICO 14 Single Use Negative Pressure Wound Therapy System, and the PICO Fluid Management Pack are indicated for patients who would benefit from a suction device (negative pressure wound therapy) as it may promote wound healing via removal of low to moderate levels of exudate and infectious materials. Appropriate wound types include: Chronic Acute Traumatic Subacute and dehisced wounds Partial-thickness burns Ulcers (such as diabetic or pressure) Flaps and grafts Closed surgical incisions PICO 7, PICO 7Y, PICO 14 Single Use Negative Pressure Wound Therapy Systems and PICO Fluid Management Pack is suitable for use both in a hospital and homecare setting.

Device Story

Canister-free, single-use negative pressure wound therapy (NPWT) system; consists of absorbent dressing connected to small NPWT pump via tubing/port. Pump utilizes custom voice-coil mechanism controlled by microprocessor to maintain -80mmHg nominal pressure under dressing. Dressing manages exudate through absorption and evaporation. Used in hospital and homecare settings by clinicians or patients. Output is negative pressure application to wound site; healthcare providers monitor wound healing progress. Benefits include promotion of wound healing through exudate removal. Subject devices are updates to existing PICO family, specifically modifying magnet safety warnings and removing pump warning labels.

Clinical Evidence

Bench testing only. Evidence includes magnetic field strength testing demonstrating field strength is weaker than common consumer electronics (laptops, phones). Systematic literature review of implantable medical devices (IMDs) and magnetic interference, combined with analysis of over 60,000 MAUDE database records and internal complaint data, confirmed no reported instances of death or serious harm related to magnetic interference from PICO devices. Previous biocompatibility (ISO 10993), electrical safety (IEC 60601-1 series), and wound model performance data from cleared predicates remain applicable.

Technological Characteristics

Canister-free NPWT system; PU plastic pump casing; custom voice-coil pump; microprocessor-controlled; -80mmHg nominal pressure; ethylene oxide sterilization. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, and ISO 10993.

Indications for Use

Indicated for patients requiring negative pressure wound therapy to promote healing via removal of low to moderate exudate and infectious materials. Applicable to chronic, acute, traumatic, subacute, dehisced wounds, partial-thickness burns, ulcers (diabetic/pressure), flaps, grafts, and closed surgical incisions.

Regulatory Classification

Identification

A powered suction pump is a portable, AC-powered or compressed air-powered device intended to be used to remove infectious materials from wounds or fluids from a patient's airway or respiratory support system. The device may be used during surgery in the operating room or at the patient's bedside. The device may include a microbial filter.

analysis. In the cleared 510(k)s for PICO 7, PICO 7Y and PICO 14 Single Use Negative Pressure Wound Therapy Systems (including PICO Fluid Management Pack), the device met requirements for:

Biocompatibility:

- FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, "Biological ● Evaluation of Medical Devices Part 1: Evaluation and Testing,"" May 1, 1995,
- International Standard ISO 10993-1 "Biological Evaluation of Medical Devices Part 1: ● Evaluation and Testing Within a Risk Management Process," as recognized by FDA.

Testing included the following:

- Cytotoxicity
- Sensitization
- . Irritation
- Systemic toxicity
- Pyrogen Testing

# Electrical Safety and Electromagnetic Compatibility:

- IEC 60601-1 ●
- IEC 60601-1-11
- IEC 60601-1-6 ●
- IEC 60601-1-2

# Wound model testing:

- Wound exudate ●
- Wound size
- NPWT Wound flow rate ●
- Testing duration
- Pressure sampling rates ●

## Magnetic Field Testing:

Bench testing demonstrated that the average magnetic field strength of PICO Family pump is weaker than multiple everyday devices (e.g. laptops, phones, tablets, and headphones). These products are abundant in today's society and do not pose an unacceptable risk to patients with implantable medical devices (IMDs). The PICO pump does not significantly change the magnetic environment an IMD user may encounter.

## Post Market and Risk Analysis:

A systematic literature review was conducted of IMDs and magnetic interference and this demonstrated that although the risk of magnetic interference with implantable medical devices exists, the risk is not as high as had been originally assessed. Magnetic fields are present in the everyday environment which are comparable with those presented by the PICO devices, however, there are no risks that have been reported in the clinical literature that relate to actual death or serious harm. A comprehensive review of over 60,000 records from the MAUDE database as well as the Smith +Nephew PICO devices complaint data confirmed the literature review outcome.

# VIII. Conclusion

Data to confirm substantial equivalence to the predicate were provided in the FDA cleared 510(k) for PICO Family of Single Use Negative Pressure Wound Therapy Systems. The proposed labeling changes are supported by updated IFUs, evaluation of risk and updated risk analysis, and magnetic strength testing. The subject devices are substantially equivalent to the predicate device.
