Abstract: A device comprises a cylinder and a tank. The cylinder includes a first disc and a second disc, multiple struts arranged orthogonally between the first disc and the second disc, and a plurality of walls, parallel to the first disc and the second disc. The struts generally form a circumference with spaces between each of the struts along the circumference; the walls extend through the space between the struts and beyond the circumference of the struts; and the walls form a plurality of tracks around the circumference of the struts. An axle extends orthogonally between the first disc and the second disc, and at least a portion of the cylinder rotates about the axle. The tank includes a basin to hold a liquid solution. When a catheter is wound around the cylinder, the rotation of the cylinder causes the catheter to be coated in the liquid solution from the basin.
