Abstract

A catheter configured to be deployed in a urinary tract of a patient includes a proximal portion configured to pass through a percutaneous opening and a distal portion including a retention portion. The retention portion is configured to be deployed in a kidney, renal pelvis, and/or bladder of the patient. The retention portion includes one or more protected drainage holes, ports or perforations and is configured, when deployed, to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports, or perforations upon application of negative pressure through the catheter.
