A system and method are provided for minimally-invasive selective fat removal from a target area by injecting the area with a solution of photo-absorbing nanoparticles and irradiating the injected area with a beam of near infrared (NIR) light. The NIR emission wavelength excites the nanoparticles to melt fat within the target area so that the liquefied fat can be aspirated from the target area. The nanoparticles may be gold nanorods having aspect ratios selected to produce surface plasmon resonance when irradiated with NIR light around 800 nm.

Methods and systems for detecting undesirable electrocautery arcing events during an electrocautery surgical procedure may include introducing an electrosurgical treatment instrument to a surgical site to perform an electrocautery surgical procedure. A healthcare provider may view the surgical site with a surgical camera assembly having a surgical field-of-view. The healthcare provider also may view a portion of the electrosurgical treatment instrument with an electrocautery arc detection system including an arc detection camera having an arc detection field-of-view different than the surgical field-of-view obtained by the surgical camera. The electrocautery arc detection system may identify thermal infrared emission or tissue color changes as indicators of undesirable electrocautery arcing. Some implementations alert a healthcare provider of undesirable electrocautery arcing.

A method for photothermolysis that includes applying galvanic current energy to skin at an area of a hair follicle and applying pulsed optical energy to the skin at the area of the hair follicle at an energy level and duration so as to cause thermal destruction of a hair papilla.

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.
