A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to heat tissue to create lesions without ablating the tissue. The system includes a first treatment device having at least one electrode for applying radiofrequency energy to tissue, a controller including a connector to which a first treatment device is coupled for use, and a generator for applying radiofrequency energy to the electrodes. The controller controls application of energy so that the tissue is thermally treated to create lesions but preventing thermal treatment beyond a threshold which would ablate the tissue.

A system for controlling operation of a radiofrequency treatment device to apply radiofrequency energy to tissue to treat tissue to create lesions without ablating the tissue. The system includes a first treatment device having a plurality of electrodes. The electrodes are maintained in axial alignment and fixed radial spacing in retracted and extended positions. The device includes a basket having a plurality of arms. The arms are maintained in a fixed radial spacing in the collapsed position of the basket.

A method, system, and device for predicting lesion quality. Specifically, lesion quality may be predicted based on an assessment of pulmonary vein occlusion using injection of an impedance-modifying agent and evaluation of changes in impedance measurements recorded by an electrode located distal to an occlusion element of the treatment device used to inject the impedance-modifying agent. The quality of the occlusion may be rated based on the changes in impedance over time within the pulmonary vein. For example, the quality of the occlusion may be rated as being good, fair, or poor. This assessment may be quickly and easily communicated to an operator.

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device an energy delivery device).

The present invention provides a medical device that may include a catheter body having proximal and distal portions, a fluid injection lumen disposed within elongate body, and a guidewire lumen disposed within the elongate body. A tip portion defining a cavity in fluid communication with the fluid injection lumen may be coupled to the distal end of the guidewire lumen, and an expandable element may be coupled to the distal portion of the catheter body and to the tip portion, such that the expandable element is in fluid communication with the fluid injection lumen. A shaping element may at least partially surround the expandable element, where the shaping element is configurable in a first geometric configuration and a second geometric configuration.
