Novel applications in catheter ablation.
ABSTRACT Catheter based treatment of arrhythmia has gained significant attention during the last two decades. Due to the explosive development in ablation treatment of atrial fibrillation, huge interest in new tools was born to help in the atrial fibrillation ablation procedures. The aim of this review is to describe the role of these novel techniques and tools aimed at improving the implementation of catheter based ablations of atrial arrhythmias by focusing on the use of intra-cardiac echocardiogram and robotic navigation.

ABSTRACT: The development of clinical data base structures frequently presents a situation in which the number and type of data items are highly variable or entire data structures require modification over time. Traditional approaches to handling such non-deterministic data (e.g., leaving space for expansion, redefining items no longer used, etc.) have frequently proven to be restrictive and occasionally counter-productive.Computer Applications in Medical Care, 1983.

ABSTRACT: A complex arrhythmia is one where successful ablation represents a serious challenge to the treating physician, and in this situation an advanced solution such as the combination of imaging with mapping and the ability to deliver a newer energy form using remote navigation may be a combined option some may wish was presently available. As will be discussed, there have been many advancements in the armamentarium of the electrophysiologist, and the above scenario may not be too far removed. This is not an exhaustive review, but serves to highlight some of the issues. Hopefully some, if not all, of the advances discussed will assist us in improving success rates, while decreasing risks and complications. The ability to allow less experienced and busy electrophysiology centers to perform complex ablation with similar success and risk as more experienced labs may also be a possibility.Journal of Cardiovascular Electrophysiology 12/2006; 18(s1):S2 - S10.

Article: Flexible robotics: a new paradigm.[Show abstract] [Hide abstract]
ABSTRACT: The use of robotics in urologic surgery has seen exponential growth over the last 5 years. Existing surgical robots operate rigid instruments on the master/slave principle and currently allow extraluminal manipulations and surgical procedures. Flexible robotics is an entirely novel paradigm. This article explores the potential of flexible robotic platforms that could permit endoluminal and transluminal surgery in the future. Computerized catheter-control systems are being developed primarily for cardiac applications. This development is driven by the need for precise positioning and manipulation of the catheter tip in the three-dimensional cardiovascular space. Such systems employ either remote navigation in a magnetic field or a computer-controlled electromechanical flexible robotic system. We have adapted this robotic system for flexible ureteropyeloscopy and have to date completed the initial porcine studies. Flexible robotics is on the horizon. It has potential for improved scope-tip precision, superior operative ergonomics, and reduced occupational radiation exposure. In the near future, in urology, we believe that it holds promise for endoluminal therapeutic ureterorenoscopy. Looking further ahead, within the next 3-5 years, it could enable transluminal surgery.Current Opinion in Urology 06/2007; 17(3):151-5. DOI:10.1097/MOU.0b013e3280e126ab · 2.12 Impact Factor
