TUBULAR FLOATING ELECTRODE DIELECTRIC BARRIER DISCHARGE FOR APPLICATIONS IN STERILIZATION AND TISSUE BONDING

摘要

Disclosed is a device and method for contacting a biological substrate. A non-thermal plasma device delivers a non-thermal plasma discharge using a dielectric conduit, an igniter electrode and a RF electrode. The dielectric conduit fluidicly communicates a gas therethrough and an igniter electrode ionizes at least a portion of the gas. The RF electrode, disposed circumferentially proximate to the exterior of the dielectric conduit, generates non-thermal plasma from the ionized gas. The non-thermal plasma is discharged from the dielectric conduit and contacts a biological substrate. The non-thermal plasma discharge may be suitable for tissue bonding and sterilization applications.

1. A method for contacting a biological substrate with non-thermal plasma, comprising:
fluidicly communicating a gas through a dielectric conduit characterized as comprising an upstream end and a downstream end, the upstream end capable of receiving gas from a gas source, and the downstream end capable of transmitting non-thermal plasma therefrom; ionizing at least a portion of the gas using an igniter electrode disposed within the upstream portion of the dielectric conduit, the igniter electrode capable of being energized to give rise to ionized gas proximately located to the igniter electrode; generating non-thermal plasma from the ionized gas using an RF electrode disposed circumferentially proximate to the exterior of the dielectric conduit, the RF electrode disposed downstream relative to igniter electrode and the gas source; and contacting the biological substrate with non-thermal plasma discharge.
