Cardioblate™ Gemini Irrigated RF Surgical Ablation System

Irrigated radiofrequency for effective box lesions in beating heart concomitant and standalone AF procedures.

Summary

Simple - Fast - Reproducible

The Medtronic Cardioblate™ Gemini™-S Surgical Ablation System combines the efficacy of irrigated RF energy with a bipolar design to create clamped box lesions in open and minimally invasive procedures.

The Gemini-S model features:

  • Cardioblate™ iRF is the only surgical ablation system that combines a smart-energy algorithm with irrigation to consistently create deep, wide lesions.
  • A moderate curve designed to facilitate a lateral port access.
  • The jaw design accommodates varying degrees of tissue thickness.
  • Flexible neck that allows for an easier procedure.
  • QuickConnect guide-jaw system creating pathways for Gemini™-S to follow in thoracoscopic procedures.
  • Handle is designed for one-handed control.

Clinical highlights

The bipolar irrigated RF box-lesion is a safe and effective procedure for minimally invasive treatment of stand-alone AF.1

Thoracoscopic PVI and box isolation is highly effective in restoring sinus rhythm in long-standing persistent AF, reaching a success rate of more than 90% after 12 months.2

The box lesions created by the irrigated Bipolar Gemini™-s clamp provide a more effective isolation of the posterior left atrium wall and pulmonary veins when compared to the non-clamping box lesion with non-irrigated Isolator®* Synergy™* and Coolrail®* Linear Pen, (Atricure, Inc.). In fact, repeat catheter interventions were required in only 10% of Gemini™-s procedures versus 21% of Isolator®* Synergy™* and Coolrail®* Linear Pen, (Atricure, Inc.).2

These findings are consistent with a recent study in which complete isolation of the posterior Left Atrial Wall was only achieved in 23% of the patients treated with Isolator®* Synergy™* and Coolrail®* Linear Pen (AtriCure, Inc.) and the majority of patients required endocardial catheter ablation to complete the linear ablation lesions.3

Important Safety Information

Possible complications related to the ablation of cardiac tissue in combination with open heart surgery are: tissue perforation, extension of extracorporeal bypass, perioperative heart rhythm disturbances (atrial and/or ventricular), postoperative embolic complications, pericardial effusion or tamponade, injury to the great vessels, valve leaflet damage, conductions disturbances (SA/AV node), acute ischemic myocardial event and thrombus formation.
