Methods, Apparatuses, and Systems of operating a laser atherectomy system to perform an endoscopic atherectomy procedure within a vessel at a therapeutic region of an anatomical condition by use of an atherectomy laser device coupled to an ultrasound imaging probe. The atherectomy laser device operates to generate photoacoustic signals from a light source of the atherectomy laser device to for guidance within the vessel and to characterize tissue about the therapeutic region by delivery of pulsed wavelengths within the vessel, and to perform operations of tissue ablation directed to the anatomical condition. This enables guidance of the atherectomy laser device by feedback from the viewing of photoacoustic images based on photoacoustic signals generated the atherectomy laser device and created in response to changes in acoustic intensity due to changes of optical wavelength monitored by the ultrasound imaging probe.

A system is configured to delivering radiofrequency power to the endometrial lining tissue of a uterine cavity, including modulating the delivered power so that a measured impedance of the endometrial lining tissue tracks a target impedance as a function of time, wherein the target tissue impedance is derived from a function that approximates a preferred endometrial lining tissue ablation impedance curve that is determined based upon a measured impedance of the endometrial lining tissue after RF power has been delivered for a predetermined initial time period.

A probe is configured with a flushing port and an evacuation port to establish a flow path to remove blood from a resected tissue. The probe comprises a balloon configured to expand and contact the resected tissue to compress filaments and improve access to the underlying blood vessels for coagulation with an energy source. An endoscope can be used to view the tissue, and the balloon may comprise a transparent material or a viewing port to allow imaging of the bleeding tissue through the balloon. The probe may have a light source to illuminate the tissue with a beam oriented at an oblique angle to the tissue surface, which can decrease interference from blood and may allow more localized coagulation of the blood vessel.
