Studying And Troubleshooting Lubricity Test On Pressure Wire X Proximal And Distal Coatings, Usama A. Khan

All Graduate Theses, Dissertations, and Other Capstone Projects

Coatings of guidewires used in medical device manufacturing industry are one of the most important element aspects. It defines its efficiency to penetrate through tightest of canals and curves. Guidewires are put through controlled environment to accelerate its age and tested for its mechanical features. Pressure Wire X failed the lubricity testing after being tested by multiple operators and at alternate sites. A cause-and-effect diagram shows all potential causes of test failure. The human factor involved in the test failure was investigated through multiple Gage R&R and training records. Calibration error with the lubricity tester DL1000 was identified and solved …
