摘要
Needle devices for accessing lymph nodes and thoracic ducts. A needle device for insertion into a lymph node and secured after access to the lymph node is described. The needle can aspirate or introduce fluids through a needle aperture in the needle sidewall. The needle may be curved. The needle device may also have a channel for fluids. The channel can have an aperture in the sidewall or be a separate channel alongside the lumen and have a distal aperture. Securing the needle can be accomplished via a hook, spiraling element, balloon or glue, which can be introduced via an open needle tip or a channel aperture. The spiraling element may be attached to a drive configured to rotate the spiraling element.
