Evaluating the Technical Specifications and Clinical Performance of Different Percutaneous Epidural Neuroplasty Catheters

This study identified substantial variations in catheter characteristics across different products. Increased catheter flexibility after guidewire removal may lead to positional instability, requiring careful consideration during PEN procedures. Larger catheter diameters were correlated with increased advancing force, which could influence ease of insertion and patient comfort. These findings emphasize the need for standardized PEN catheter specifications to optimize safety and efficacy in clinical practice.
