Deflectable renal nerve ablation catheter

摘要

Medical devices including catheters for renal nerve ablation and/or modulation as well as methods for making and using such devices are disclosed. An example catheter may, have a proximal region and a distal region. The catheter may be configured to shift between a first straightened configuration and a second deflected configuration. The catheter may also include an ablation member coupled to the distal region and a handle coupled to the proximal region. The handle may include an actuation member for shifting the catheter between the first configuration and the second configuration. A lock may be coupled to the handle that maintains the catheter in either the first configuration or the second configuration.
