LapEvac, designed for use during laparoscopic surgery, will help reduce many of the risks associated with poor vision and loss of distension due to smoke & efforts to clear smoke and aerosols from the patient?s cavity. This system is the world?s first disposable, battery powered smoke evacuator that creates a constant closed loop flow to filter and re-circulate gas within the peritoneal cavity. LapEvac uses 99.999% efficient ULPA filter media with activated carbon to remove smoke plume and aerosols. This small, sterile unit connects to two trocars and quietly runs throughout the surgical procedure. LapEvac keeps the surgeon?s view clear from smoke, minimizes the amount of CO2 gas needed to keep the patient?s cavity distended, and also helps reduce the amount of plume byproducts remaining in the patient?s cavity. LapEvac is a self-contained, sterile system powered by 4 pre-installed AA batteries. Estimated operational life for LapEvac is typically 3 1/2 - 4 hours.
