Abstract
A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.
