System with vibration device and cooling fluid for interstitial laser therapy

Abstract

Disclosed is a system provided with a vibration device and cooling fluid for interstitial laser therapy. Use of the vibration device to vibrate at least part of the system releases and assists in the transfer of gas bubbles (e.g. steam) produced during treatment use, thus stabilising the temperature at or near a treatment site. The system for interstitial laser therapy includes an optical waveguide having an optical output end and an associated optical diffuser, an irrigation tube, an outer tube (e.g. cannula) and a vibration device. The irrigation tube directs cooling fluid to flow out of a distal end of the irrigation tube which directs cooling fluid to flow inside of and/or outside of the optical diffuser. The vibration device is used to vibrate the irrigation tube, the optical diffuser and/or the outer tube.
