Steerable catheters in minimally invasive vascular surgery

THE INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY, Issue 4 2009
Yili Fu
Abstract Background Remote-controlled catheter navigation systems have recently been introduced into minimally invasive vascular surgery and some of them have already been applied in clinical practice. Steerable catheters with improved manoeuvrability play an important role in these innovations for conventional catheterization. Methods This review details the development of various steerable catheters, both in use clinically and under investigation. Comprehensive comparison and analysis in several key aspects are followed to reveal both the advantages and limitations of these catheters, as well as the requirements for relevant techniques. Results Steerable catheters are able to select direction in the distal end, and superior to conventional counterparts in many aspects. Differences between magnetic and active catheters mainly lie in function, safety, configuration of operating room and cost. They have similar requirements for miniaturization and slave insertion mechanisms. Conclusions Steerable catheters are rapidly evolving and still require technological refinements to extend current capabilities. Copyright © 2009 John Wiley & Sons, Ltd. [source]

Endocardial Ventricular Pacing Through a Bioprosthetic Tricuspid Valve

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 2 2007
DANTE ANTONELLI M.D.
A patient with bioprosthetic tricuspid valve was treated with ventricular endocardial pacing using a new delivery system consisting of a steerable catheter and a 4.1 F bipolar, fixed-screw, steroid eluting lead. The functioning of the lead and bioprosthetic tricuspid valve was excellent during the following year. [source]
