The present disclosure provides a method and a system for treating a tissue using photodynamic therapy (PDT). A photosensitizer is administered to the tissue and one or more optical fibers are placed in the tissue. A treatment light is applied to the tissue by way of the one or more optical fibers. A temperature of the tissue is measured during application of the treatment light, and a fluence rate of the treatment light is modified based on the temperature of the tissue. For example, the fluence rate may be modified to be lower if the temperature of the tissue is higher than a predetermined threshold.)

Devices and methods for monitoring the temperature of tissue at various locations in a treatment volume during fluid enhanced ablation therapy are provided. In one embodiment, an ablation device is provided having an elongate body, at least one ablation element, and at least one temperature sensor. The elongate body includes a proximal and distal end, an inner lumen, and at least one outlet port to allow fluid to be delivered to tissue surrounding the elongate body. The at least one ablation element is configured to heat tissue surrounding the at least one ablation element. The at least one temperature sensor can be positioned a distance away from the at least one ablation element and can be effective to output a measured temperature of tissue spaced a distance apart from the at least one ablation element such that the measured temperature indicates whether tissue is being heating to a therapeutic level.

A dispersive return pad for a radiofrequency ablation procedure includes a skin material adapted to be worn on a patient's skin, a conductive material positioned adjacent to the skin material, a non-conductive material surrounding the conductive material, and a phase-change material surrounding at least a portion of a side edge of the conductive material. Further, the phase-change material is configured to undergo a phase transition at a target temperature range corresponding to a non-damaging hyperthermic temperature range for the patient's skin. As such, the phase-change material is configured to absorb excess heating from the RF ablation procedure and to prevent burns to the patient's skin.

The present disclosure provides, according to some embodiments, methods and systems for selectively reducing, blocking or inhibiting at least part of the neural activity in an organ of a subject. In preferred embodiments, the method and system are used for selectively blocking at least part of the neural activity in a duodenum of a subject in need thereof. According to some embodiments, the selective blocking occurs through use of laser radiation. According to some embodiments, the selective blocking occurs through use of ultrasound energy. According to some embodiments, the selective blocking comprises causing damage to at least part of sensory nerves located within a target area while maintaining functional activity of tissue surrounding the sensory nerves by means of shielding it from the effects of laser radiation. According to some embodiments, the sensory nerves include neurons configured to transmit signals triggered by food passing through the duodenum, such as, but not limited to, neurohormonal signals.
