Abstract
A catheter device and manufacturing process for manufacturing the catheter device, wherein the catheter device has a halo-shaped coiled portion extending away from a perpendicular stem portion through a swan neck portion. Eyelets on the halo coil portion and swan neck portion facilitate flow out of the bladder through the catheter device vertical to the catheter, rather than perpendicularly as is the case with existing catheters. The catheter device is formed by using a straight catheter tube, heating and cooling it within a formed mold to have the halo coil and swan neck, such that it can be straightened using a pusher and stylet, inserted into the body while straightened, and thereafter return to its coiled shape when the stylet is removed.
