Abstract: Catheters for debonding fouling agents from an interior surface thereof and related methods are disclosed. According to an aspect, a catheter includes a lumen defining a flexible, interior surface that extends substantially along a length of the lumen for contacting a biological material. The catheter also includes cavities extending along the length and positioned within the lumen adjacent to the surface. The cavities each define a cavity opening. The catheter also includes an inflation hub defining hub openings connected to respective cavity openings. The inflation hub defines a pump port configured to interface with a pump. The inflation hub defines one or more fluid pathways that extend between the hub openings and the pump port for permitting flow of gas between the pump and the cavities.

Abstract: Disclosed herein are devices and methods for active biofouling control. According to an aspect, a device comprising a surface for contacting a biological material. The device also comprises a mechanism comprising a structure configured to change the surface between a first shape and a second shape. The change from the first shape to the second shape deforms the surface beyond a critical strain for debonding of a fouling agent from the surface when the fouling agent has bonded to the surface in the first shape.
