Trial Outcomes & Findings for Predictive Factors of a Successful Implant of the CapsureFix MRI Model 5086 (NCT NCT01522755)

NCT ID: NCT01522755

Last Updated: 2025-07-02

Results Overview

Ease of implant as experienced by the implanting physician on maneuverability of the catheter. This was measured by a questionnaire for which each criterion was coded as Very Good, Good, Fair, Poor, Very Poor. Coding 9, 7, 5, 3, 1 was applied for each response with 9 representing Very Good. An average was calculated for each evaluation and for each probe implantation site.
