Abstract: A self-catheterization aid for use by male patients having impaired wrist, hand and finger movement due to traumatic spinal cord injury or neuromuscular diseases. The self-catheterization aid comprises a strip of flexible material having an arcuate semi-annular shape. The patient fits the device around his penis to form a circumferential tubular support platform that stabilizes the penis to allow for self-catheterization with either an indwelling catheter or an intermittent internal catheter. The device is easily manipulated by patients having impaired hand and wrist movement.
