Clinical Trial Summary

The Linear II study is a prospective, single center, non-randomized, interventional feasibility study with the purpose of assessing acute safety of the Multi-Electrode Linear Type Ablation Catheter and the performance of the product when used for the treatment of symptomatic CTI (cavotricuspid isthmus) dependent right atrial flutter.

- Uncontrolled heart failure or NYHA function class IV

- MI within the past 2 months

- Any cardiac surgery (i.e. CABG) within the past 2 months

- Subjects that have ever undergone valvular cardiac surgical procedure (ie, ventriculotomy, atriotomy, and valve repair or replacement and presence of a prosthetic valve)

- Awaiting cardiac transplantation or other cardiac surgery within the next 6 months

- Documented thromboembolic event (including TIA) within the past 12 months

- Significant congenital anomaly or medical problem that in the opinion of the investigator would preclude enrollment in this study

- Unstable angina

- History of blood clotting or bleeding abnormalities

- Contraindication to anticoagulation (eg, heparin or warfarin)

- Life expectancy less than 6 months

- Presence of intracardiac thrombus, myxoma, interatrial baffle or patch, tumor or other abnormality that precludes catheter introduction or manipulation

- Presence of a condition that precludes vascular access

Outcome

Type Measure Description Time frame Safety issue
Primary Safety Incidence of early onset (within 7 days of ablation procedure) primary AEs 7 Days Yes
Primary Acute performance Acute procedural success as confirmed complete bidirectional conduction block across the CTI (assess =30 min following last RF application) This outcome measure will be assessed during the procedure but after 30 minutes (or more) of the initial ablation No
Secondary Safety Incidence of Serious Adverse Events during follow-up Until one-month follow-up Yes
Secondary Acute Efficacy Right atrial flutter recurrence within 30 days Within 30 Days No
Secondary Procedural data Ablation parameters, including:
Total RF ablation time
Temperature
Contact Force Procedural time Total fluoroscopy time
During Procedure No
