DOUBLE MICRO-ELECTRODE CATHETER

摘要

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter for use in cardiac mapping and/or ablation. The catheter may include an elongate catheter shaft having a distal ablation electrode region capable of ablating tissue. A plurality of micro-electrode assemblies may be coupled to the distal ablation electrode region. At least one of the micro-electrode assemblies may include an inner electrode and an outer electrode disposed at least partially around the inner electrode. At least one of the inner electrode and the outer electrode may comprise a sensor.
