Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Magnetecs Catheter Guidance Control and Imaging (CGCI) system is a magnetic remote navigation system which is comprised of a magnetic chamber of eight electromagnets around the patient torso. The system can change the magnetic field almost instantaneously and enables almost real time manipulation of a special magnetic catheter (Maxwell mapping catheter) which results in accurate, repeatable, rapid and safe target acquisition within the four chambers of the human heart.

The trial is a prospective, non-randomized, clinical one designed to test the study hypotheses of (a) technical equivalence of the study device in comparison to other magnetic remote navigation systems, (b) performance equivalence or non-inferiority of the study device target acquisition capability compared to presently used catheter navigation techniques, and (c) safety equivalence or non-inferiority of the study device in comparison to catheter navigation devices using other navigation techniques.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The CGCI system is comprised of (a) magnetic chamber of eight electromagnets around the patient torso, (b) the Maxwell ©, a 7Fr. Inquiry™ catheter with an attached magnetic pellet manufactured by St. Jude Medical, Inc. The Maxwell © is equivalent to a 7 Fr. Inquiry™ cleared under 510(K) K022380, and (c) a Agilis ES Active Sheath© which is a modified 7.5 Fr. Steerable Introducer is equivalent to the Agilis NxT™ Steerable Introducer, manufactured by St. Jude Medical, Inc. and cleared under 510(K) K061363.

Study Rationale: Current manual manipulations of mapping catheters are imprecise and difficult to control. The Magnetecs CGCI system enables almost real time manipulation of the Maxwell mapping catheter which results in accurate, repeatable, rapid and safe target acquisition. The CGCI System is intended to navigate a magnetic catheter within the four chambers of the human heart by orienting and moving the catheter tip to designated anatomically significant targets.

Design: A prospective, non-randomized, clinical trial designed to test the study hypotheses of (a) technical equivalence of the study device in comparison to other magnetic remote navigation systems, (b) performance equivalence or non-inferiority of the study device target acquisition capability compared to presently used catheter navigation techniques, and (c) safety equivalence or non-inferiority of the study device in comparison to catheter navigation devices using other navigation techniques.

Target Population:Patients who have recurrent cardiac rhythm disturbances and who meet clinically recognized indications for performance of an intracardiac mapping procedure.

Planned Number of Subjects: A total of 40 patients

Study Objectives: This study is designed to collect data to test the target acquisition performance efficacy and safety of the CGCI for intracardiac navigation.

The objective is to achieve the navigation performance criteria for the primary efficacy endpoints for reaching preselected anatomically significant targets in the right and left heart chambers, respectively. The secondary efficacy endpoints are obtained by measurements of stimulation thresholds at selected anatomic sites, and by analyzing surface and intracardiac signal recordings during target acquisition with the CGCI magnetic system.

The primary safety endpoints are defined as the rate of procedure related incidence of serious acute Adverse Events due to manipulation of the magnetic catheter. Verification of these adverse events will be by fluoroscopy, echocardiograms and physician observations, and the results will be subjected to statistical evaluation.

The claims of substantial technical equivalence to other magnetic remote navigation systems will be verified by collecting data at the outset of each clinical procedure, measuring maximum magnetic field strength at the center region and around the outside perimeter of the CGCI device, and by measuring the maximum force available at the catheter tip.

Success will be evaluated in accordance with the primary efficacy and safety endpoint specifications, and by the technical equivalency tests. Data collection and sample size are defined to comply with FDA (1992) 80/20 ruling to adequately power the hypothesis tests.
