Abstract

A gas enriched foam generating apparatus for performing medical procedures includes a foam generating tip assembly composed of a multi-channel arrangement at a proximal first end thereof and a tip at a distal second end thereof. The apparatus also includes a compressed gas unit fluidly connected to the multi-channel arrangement at a proximal first end of the foam generating tip assembly and a medical solution fluidly connected to the multi-channel arrangement at a proximal first end of the foam generating tip assembly. Compressed gas, from the compressed gas unit, and the medical solution are combined within the foam generating tip assembly in a manner generating a gas enriched foam that is ultimately dispensed from the foam generating apparatus.

First claim
