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. The straight design is for patients who have chronic bladder problems and able to perform the catheterization themselves.
