A steerable catheter having a catheter tip connected to an elongated catheter body, with the catheter tip having an elastomeric cylindrical body and one or more steering lumens each offset from the longitudinal axis of the elastomeric cylindrical body and extending substantially the length of the elastomeric cylindrical body so that increasing the internal pressure of one or more of the steering lumens using, for example, a pneumatic or hydraulic pressure source or heating a thermally expandable media in the steering lumens, operates to curl the longitudinal axis of the elastomeric cylindrical body towards the internally pressurized steering lumen or lumens for steering the catheter tip.
