Intended Use
The Medela® Invia Liberty Negative Pressure Wound Therapy System is indicated to help promote wound healing, through means including drainage and removal of infectious material or other fluids, under the influence of continuous and/or intermittent negative pressures, particularly for patients with chronic, acute, traumatic, subacute and dehisced wounds, partial-thickness burns, ulcers (such as diabetic or pressure), flaps and grafts.
Device Description
The Medela Invia Liberty Negative Pressure Wound Therapy (NPWT) System is comprised of the Invia Liberty NPWT Pump, canister/tubing set, power supply, carrying case, patient and user instructions, and Invia NPWT kits. The Invia Liberty is also compatible with Avance NPWT kits manufactured by Mölnlyke Healthcare. The Invia Liberty NPWT pump is a suction pump for Negative Pressure Wound Therapy with an optical and acoustic status display. Acoustic and optical signals are triggered for variances from the set values as well as for faults. The Invia Liberty NPWT pump provides continuous or intermittent operation. The Invia Liberty NPWT system may be used in a home or other health care facility by medical personnel or trained lay users adhering to the instructions for use. The user may not be hard of hearing or deaf and must have normal visual acuity. The Invia Liberty NPWT pump is portable and can be operated independent of the electrical power supply via its rechargeable battery.

No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and the device description focuses on standard pump functionality and safety features.

Yes
The device is indicated to help promote wound healing through drainage and removal of materials under negative pressure, which directly treats a medical condition.

No

The device is designed to promote wound healing by applying negative pressure to remove fluids and infectious material. It is a therapeutic device, not a diagnostic one, as it does not diagnose medical conditions.

No

The device description explicitly states that the system is comprised of a pump, canister/tubing set, power supply, carrying case, and kits, in addition to instructions. It also mentions hardware integration testing and electrical safety testing, indicating the presence of physical hardware components.

Based on the provided information, the Medela® Invia Liberty Negative Pressure Wound Therapy System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use clearly describes a therapy applied directly to a wound on a patient's body to promote healing by removing fluids and infectious material. This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
  • Device Description: The device is a suction pump and associated components designed to apply negative pressure to a wound. This aligns with a therapeutic device, not an IVD.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis. The device's function is purely mechanical/physical in its application to the wound.

In Vitro Diagnostics are devices intended for use in the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Medela Invia Liberty system does not fit this definition.

DEVICE DESCRIPTION:

The Medela Invia Liberty Negative Pressure Wound Therapy (NPWT) System is comprised of the Invia Liberty NPWT Pump, canister/tubing set, power supply, carrying case, patient and user instructions, and Invia NPWT kits. The Invia Liberty is also compatible with Avance NPWT kits manufactured by Mölnlyke Healthcare.

The Invia Liberty NPWT pump is a suction pump for Negative Pressure Wound Therapy with an optical and acoustic status display. Acoustic and optical signals are triggered for variances from the set values as well as for faults. The Invia Liberty NPWT pump provides continuous or intermittent operation.

The Invia Liberty NPWT system may be used in a home or other health care facility by medical personnel or trained lay users adhering to the instructions for use. The user may not be hard of hearing or deaf and must have normal visual acuity. The Invia Liberty NPWT pump is portable and can be operated independent of the electrical power supply via its rechargeable battery.

INTENDED USE:

The Medela® Invia Liberty Negative Pressure Wound Therapy System is indicated to help promote wound healing, through means including drainage and removal of infectious material or other fluids, under the influence of continuous and/or intermittent negative pressures, particularly for patients with chronic, acute, traumatic, subacute and dehisced wounds, partialthickness burns, ulcers (such as diabetic or pressure), flaps and grafts.

DETERMINATION OF SUBSTANTIAL EQUIVALENCE:

SUMMARY OF TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE COMPARED TO THE PREDICATE DEVICE

The Invia Liberty NPWT System uses the same fundamental technology as Invia Wound Therapy (K080357) for most features. The Invia Liberty NPWT System is identical to the Invia Wound Therapy in its indications for use and contraindications. The main differences between the Invia Liberty NPWT System and the predicate Invia Wound Therapy are:

  • New double lumen pump tubing with quick connector coupling. The smaller lumen (air flush tubing) flushes air to remove exudate from the larger lumen. Larger lumen (suction tubing) removes the fluid from the wound into the canister. The quick connector will ensure that the connection is easy to connect / disconnect and tight.
  • . New Drain Adapter to connect quick connect tubing to drains
  • New Y-Connector for quick connect compatibility
  • Firmware change, including improved flush algorithm
  • Housing material change to ABS to improve the stability and cleanability
  • Additional IFU for patient in home care environment
