Abstract
Devices and methods used to drain a spinal cyst are disclosed. An opening may be created by a medical device, such as a nested needle assembly, that is inserted percutaneously into a facet joint adjacent to the cyst. The needle assembly may include a first elongate member, needle or introducer cannula; a second elongate member, inner cannula, needle, or trocar; and a piercing needle. The piercing needle may be used to microfenestrate a wall of the cyst such that fluid within the cyst is permitted to drain from the cyst.
