intrathecal injection

Lumbar intrathecal access port implantation for Cerebrospinal fluid (CSF) collection and/or intrathecal infusion in the non-human primate is being requested more frequently in the Safety Assessment world of biomedical research. Historically, performing a hemi-laminectomy to visualize and access the spinal dura for catheter cannulation has been the gold standard for the placement of these access catheters. There is an alternative. A minimally invasive technique using a Tuohy needle to access the intrathecal space and the advancing of an access catheter through this needle into the IT space with the need to perform a hemi-laminectomy, has proven to be an advantageous technique [...]
