The Lumbar Catheter application segment is divided into Spinal Anesthesia and Lumbar Drainage. Spinal Anesthesia, accounting for 65% of the market, is widely utilized in surgeries requiring rapid, localized nerve blockades, driven by rising orthopedic and urological procedures. Lumbar Drainage, representing 35%, addresses cerebrospinal fluid (CSF) management in neurological disorders, trauma, or post-operative care. Growth in this segment correlates with increasing neurological disease prevalence and procedural adoption in neurosurgical settings. Both applications directly influence market dynamics, with Spinal Anesthesia dominating due to procedural frequency and cost-efficiency.
