1. A method for aspirating and treating a cyst comprising:
- piercing a cyst with a first needle assembly until a distal tip of said first needle assembly is positioned in the region of the apex of the cyst, said first needle assembly comprising a first trocar and a first stylet;
piercing the cyst with a second needle assembly until a distal tip of said second needle assembly is positioned towards the far side of the cyst generally opposite said apex, said second needle assembly comprising a second trocar and a second stylet;
removing said first and second stylets and aspirating the contents of the cyst through said second trocar, said first trocar providing a vent to neutralize pressure variations within said cyst;
injecting a tissue sealant into the aspirated cyst through said second trocar.

Abstract
A method and kit for aspirating and treating a cyst is provided. In an embodiment, the method comprises aspirating fluid from the cyst through a first lumen, while venting the cyst using a second lumen, so as to stabilize pressure variations within the cyst. The aspirated cyst is then injected with a tissue sealant using the second lumen, while continuing to vent the cyst using the first lumen. To enhance visualization of the tissue sealant during imaging, the tissue sealant may be augmented so as to increase its radio-opacity.
