The McKesson Intermittent Catheters are high-quality intermittent catheters designed for quick and easy self-catheterization. These non-coated catheters are manufactured from clear polyvinyl chloride (PVC)and they are indicated for intermittent catheterization of the urethra for those individuals who are unable to promote a natural urine flow or for those individuals who have a significant volume of residual urine following a natural bladder-voiding episode. McKesson Urethral Catheters are designed to be inserted into the urethra to reach the bladder allowing urine to drain. These catheters contain staggered eyes for maximum urine flow; the polished eyes minimize urethral trauma and reduce the risk of bringing bacteria into the bladder.
