Abstract
Devices and methods for efficiently and reproducibly heating fluid for use in fluid enhanced ablation are disclosed herein. In one embodiment, an ablation device is provided having an elongate body, at least one wire extending through an inner lumen of the elongate body, and at least one spacer disposed within the inner lumen. The at least one wire extends through the at least one spacer such that the at least one spacer is effective to maintain an adjacent portion of the at least one wire in a substantially fixed geometric relationship with the inner lumen, thereby preventing electrical shorts and providing for the consistent and uniform heating of fluid flowing through the inner lumen of the elongate body.
