Anatomy of the Gertie Marx Spinal Needle

Not all spinal needles are created equally. There are a number of reasons why the Gertie Marx atraumatic spinal needle outperforms its competitors.


One of the most impressive features of the Gertie Marx needle is its patented tip. They are designed to fit perfectly in the subarachnoid space. The Gertie Marx tip creates a very distinct “pop” when the dura is punctured. Due to this design, the Gertie Marx needle is the only needle on the market that reduces the occurrence of PDPH to less than 1%.


The Gertie Marx Needle is offered in the largest variety of spinal needle sizes on the market, ranging in widths from 22G to 27G and in lengths from 50mm to 215mm (2” to 8.5”). Whether you have a pediatric patient who needs a smaller needle or a larger patient who would benefit from the extended length, we have the size to fit them properly.


Our atraumatic needle has thin walls and is engineered to fit the dural space perfectly, allowing for fast flash of CSF to confirm needle placement.
