Intended Use

The V.A.C.® Ulta Negative Pressure Wound Therapy System is an integrated wound management system that provides Negative Pressure Wound Therapy (V.A.C.® Therapy) with an instillation option (Veraflo™ Therapy). V.A.C.® Therapy in the absence of instillation is intended to create an environment that promotes wound healing by secondary or tertiary (delayed primary) intention by preparing the wound bed for closure, reducing edema, promoting granulation tissue formation and perfusion, and by removing exudate and infectious material. Veraflo™ Therapy is indicated for patients who would benefit from vacuum assisted drainage and controlled delivery of topical wound treatment solutions and suspensions over the wound bed. The V.A.C.® Ulta Negative Pressure Wound Therapy System with and without is indicated for patients with chronic, acute, traumatic, sub-acute and dehisced wounds, partial-thickness burns, ulcers (such as diabetic, pressure and venous insufficiency), flaps and grafts. V.A.C.® Therapy in the absence of instillation may also be used for: The temporary bridging of abdominal wall openings where primary closure is not possible and/or repeat abdominal entries are necessary and for open abdominal wounds with exposed viscera including, but not limited to, abdominal compartment syndrome. The intended care setting is a closely monitored area within the acute care hospital, such as the ICU. The abdominal dressing will most often be applied in the operating theater. The management of the environment of surgical incisions that continue to drain following sutured or stapled closure by maintaining a closed environment and removing exudate via the application of negative pressure wound therapy.

Device Story

Integrated wound management system providing negative pressure wound therapy (NPWT) and instillation therapy. System comprises vacuum pump, instillation pump, tubing, and foam dressings. Vacuum pump removes exudate; instillation pump delivers topical solutions. Used in acute care/ICU settings by clinicians. Software monitors pressure, controls therapy parameters, and manages alarms. New Smart Instill™ feature determines solution volume based on pressure decay after negative pressure application. Clinicians use touch screen interface to set parameters and view therapy status. System promotes wound healing by reducing edema, removing infectious material, and preparing wound bed for closure. Benefits include controlled wound cleansing and automated exudate removal.

Clinical Evidence

No clinical tests were necessary. Human factors engineering assessment conducted with 30 nurses and doctors confirmed new features are safe and usable.

Technological Characteristics

Software-controlled vacuum and instillation pumps. Components include PVC tubing, polyurethane drapes, and foam dressings. System features touch screen interface, custom lithium battery, and AC power. Connectivity includes on-device monitoring and alarm systems. Software-based pressure sensing and control.

Indications for Use

Indicated for patients with chronic, acute, traumatic, sub-acute, dehisced wounds, partial-thickness burns, ulcers (diabetic, pressure, venous insufficiency), flaps, and grafts. Also indicated for temporary bridging of abdominal wall openings and management of draining surgical incisions. Contraindications not specified.

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.

## Device description [21 CFR 807.92(a)(4)]

The V.A.C. 8 Ulta Negative Pressure Wound Therapy System is a negative pressure wound therapy system with an instillation feature which allows controlled delivery and drainage of topical wound treatment solutions and suspensions. The unit is comprised of a vacuum pump and an instillation pump. The vacuum pump delivers negative therapy for the removal of wound exudate and instilled solutions when applied. The instillation pump provides controlled delivery of topical wound solutions and suspensions. Both pumps are software controlled. Instillations and negative pressure are delivered through tubing to foam dressings in the wound covered by an occlusive drape. Software monitors both negative pressure wound therapy as well as positive pressure during instillation of fluids to the wound bed. Software also provides controls for setting therapy parameters as well as help and alarm functions.
