Multifunctional Balloon Catheter

Multifunctional Balloon CatheterMaterials that integrate directly with the thin elastic membranes of otherwise conventional balloon catheters can provide diverse, multimodal functionality suitable for clinical use. As examples, we present sensors for measuring temperature, flow, tactile, optical and electrophysiological data, together with radiofrequency electrodes for controlled, local ablation of tissue. Use of such 'instrumented' balloon catheters in live animal models illustrates their operation, as well as their specific utility in cardiac ablation therapy.
