Abstract: A new flexible surgical drain/catheter system is provided. The flexible system encompasses a flexible section that can be incorporated in the design of surgical drains/catheters of any kind. By incorporating this flexible system, a surgical. drain/catheter will possess three significant additional characteristics. These additional characteristics will make the herein designs superior to the existing designs. The first characteristic is that the surgical drain/catheter can be bent without causing any fold/crease to its outer and inner surfaces. The second characteristic prevents internal occlusions while the drain/catheter is bent. The third characteristic is that the flexible section can also be used as a reliable region of drain/catheter anchorage to the patient's body.
