Nephrostomy Pigtail Drainage Catheter and Percutaneous Nephrostomy Set, Pigtail Drainage Catheter Needle Set, and Multipurpose Drainage Catheter and Set 25 April 2018 # Technological Characteristics: Performance and biocompatibility testing was conducted in accordance with applicable standards to confirm the reliable performance of device characteristics. The following tests have been conducted on the drainage catheters, subject of this submission, to ensure reliable design and performance under the specified design requirements: - Catheter/Set Compatibility Testing performed demonstrated the drainage . catheters and sets met the compatibility requirements. - Simulated Bile Soak Test articles studied in tensile, gravity flow rate, and kink . testing had undergone simulated bile soak prior to the tests. - . Tensile Testing – Testing performed on the components per applicable ISO and USP standards demonstrated that the devices met the acceptance criteria. - Gravity Flow Rate Testing Testing performed prior to kink and after kink . testing per applicable standards demonstrated that the devices met the acceptance criteria. - Kink Testing Testing characterized the kink radius of the drainage catheters. . - Radiopacity Testing Testing performed per applicable standards demonstrated . that the radiopacity of the drainage catheters met the acceptance criteria. - . Lubricity Testing – Testing performed demonstrated that the lubricity of the drainage catheters met the acceptance criteria. - . MRI Compatibility - Testing established the conditions for safety of the drainage catheters in the MR environment according to applicable standards. - . Biocompatibility Testing - Per ISO 10993-1 and FDA guidance, testing for Cytotoxicity, Sensitization, Irritation, Acute Systemic Toxicity, Subacute Toxicity, Subchronic Toxicity, Genotoxicity, and 4- and 13-Weeks Implantation demonstrated that the devices are biocompatible. For these tests, all pre-determined acceptance criteria were met. # Conclusion The results of the testing provide reasonable assurance that the subject devices have been designed so that they conform to the requirements of their intended use. The available evidence demonstrates that the subject devices are substantially equivalent to the predicate device, the Exodus Array Multipurpose Drainage Catheter, Exodus Nuance Nephrostomy Drainage Catheter, and Exodus Believe Biliary Drainage Catheter, cleared on September 24, 2015 (K152069).
