PICO 7 Single Use Negative Pressure Wound Therapy System, PICO 14 Single Use Negative Pressure Wound Therapy System and PICO Fluid Management Packs 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)
- Venous Leg Ulcers - PICO can be used in combination with Graduated Compression Therapy in the management of Venous Leg Ulcers
- Flaps and grafts
- Closed surgical incisions
PICO 7 Single Use Negative Pressure Wound Therapy Systems, PICO 14 Single Use Negative Pressure Wound Therapy Systems and PICO Fluid Management Packs are suitable for use in both a hospital and homecare setting.
The PICO 7 and PICO 14 Single Use Negative Pressure Wound Therapy Systems consist of:
• PICO Pump
• Batteries
• PICO Dressing (s)
• Instructions for Use
• Fixation Strips
PICO Fluid Management Packs consist of 5 individually packaged PICO dressings designed for use with PICO devices.
PICO 7 and PICO 14 are canister-free single use Negative Pressure Wound Therapy Systems and use an absorbent dressing connected to the PICO pump via a tubing and port.
Wound exudate is managed by PICO dressing using a combination of absorption and evaporation. The PICO pump provides the additional benefit of -80mmHg nominal pressure under the dressing, applying Negative Pressure Wound Therapy to the wound.
The provided text does not contain information about acceptance criteria for a device's performance, nor does it detail a study designed to prove the device meets specific performance criteria.
The document is an FDA 510(k) clearance letter and an accompanying 510(k) summary for the PICO 7 and PICO 14 Single Use Negative Pressure Wound Therapy Systems. The primary purpose of this submission is to demonstrate substantial equivalence to a previously cleared predicate device (K202157) for an expanded Indication for Use: the use of PICO in combination with Graduated Compression Therapy in the management of Venous Leg Ulcers.
Therefore, the requested information regarding acceptance criteria and a study proving the device meets those criteria, specifically concerning the performance of the device itself (e.g., accuracy, sensitivity, specificity for an AI/algorithm-based device), cannot be extracted from this document.
The document does include:
- Clinical information (Page 6-7): References a Randomized Controlled Trial (RCT) by Kirsner et al. (2019) and a Cochrane Review by O'Meara et al. (2012) to demonstrate the safety of PICO when used with compression therapy for Venous Leg Ulcers, especially regarding adverse events (AEs). This is a safety comparison, not a performance study against acceptance criteria.
- Study Design: Randomized, multi-centre, open-label, controlled trial.
- Sample Size: 164 patients for safety analysis. 101 subjects with venous leg ulcers (VLU) and 60 subjects with diabetic foot ulcers were in the ITT population (n=161 total). 80 received PICO treatment, of which 51 (63.8%) had a VLU.
- Data Provenance: Not specified, but likely multi-center, implying various locations. Retrospective or prospective is not explicitly stated, but RCTs are typically prospective.
- Ground Truth: The study evaluated adverse events and their frequency, comparing them to historical controls. The "ground truth" here is the occurrence and classification of adverse events by clinical observation as per the study protocol.
- Acceptance Criteria (Safety): The conclusion drawn is that "PICO used in conjunction with compression therapy does not generate any increased frequency in the number or severity of AEs in patients compared to compression therapy alone." This acts as a comparative safety criterion rather than a performance metric.
- Reported Device Performance (Safety): Percentage of subjects reporting a device-related AE was 13.7% for PICO + 4-Layer Bandage (4LB) group, compared to 31.9% for historical 4LB control.
- Experts, Adjudication, MRMC studies, Standalone Performance, Training Set: These are not relevant to the safety study presented in the document, which focuses on device-related adverse events in patients, not on an algorithmic or AI performance.
§ 878.4780 Powered suction pump.
(a)
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.(b)
Classification. Class II.
