Intended Use

The RENASYS White Foam NPWT Dressing is a moist, sterile, polyvinyl alcohol (PVA) foam intended to be used in conjunction with Smith & Nephew RENASYS TOUCH and RENASYS GO Negative Pressure Wound Therapy (NPWT) Systems. The Smith & Nephew RENASYS system is indicated for patients who would benefit from a suction pump (Negative Pressure Wound Therapy) as it may promote wound healing via the removal of wound fluids, including irrigation of body fluids, wound exudates and infectious materials.

Device Story

RENASYS-WF White Foam NPWT Dressing is a sterile, moist PVA foam wound filler; used as an interface between wound bed and negative pressure wound therapy (NPWT) system. Device functions by facilitating suction of wound exudates, irrigation fluids, and infectious materials when connected to Smith & Nephew RENASYS TOUCH or RENASYS GO pumps. Used in clinical and home environments by healthcare professionals or patients/caregivers. Dressing maintains moist wound environment; promotes healing via fluid removal. Output is physical removal of wound fluids; clinical decision-making relies on visual assessment of wound healing progress and exudate management. Benefits include effective wound bed preparation and exudate control.

Clinical Evidence

No clinical data submitted. Substantial equivalence supported by bench testing, including wound model testing in challenge conditions, comparative wound model testing against the predicate, and biocompatibility testing per ISO 10993.

Technological Characteristics

Material: Polyvinyl alcohol (PVA) foam, moistened with water. Dimensions: 7.5 x 10 x 1 cm and 15 x 10 x 1 cm. Sterilization: Gamma irradiation. Packaging: Polyethylene inner and aluminum foil outer pouch. Connectivity: Passive component for use with RENASYS NPWT systems.

Indications for Use

Indicated for patients requiring negative pressure wound therapy to promote healing via fluid removal. Appropriate for chronic, acute, traumatic, sub-acute, and dehisced wounds; ulcers (pressure or diabetic); partial-thickness burns; flaps; and grafts. Contraindicated for untreated osteomyelitis; exposed arteries, veins, organs, or nerves; necrotic tissue with eschar; malignancy in the wound; non-enteric and unexplored fistulas; and exposed anastomotic sites.

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.
