A treatment apparatus system includes a plurality of needles configured to provide radio frequency energy, a source of radio frequency energy for supplying radio frequency energy to the plurality of needles, and a driving unit configured to insert the plurality of needles to different dermal depths. A user interface is configured to allow a user to select a plurality of depths the needles are to be inserted and, at each depth, an energy level to be applied. A controller subsystem is responsive to a user selected plurality of depths and a user selected energy level at each depth and is configured to control the driving unit to insert the plurality of needles to the user selected plurality of depths and, at each depth, control the source of radio frequency energy to apply the user selected energy level. A computer safety routine is configured to limit a user selected energy level when a user selected depth is less than a predetermined minimum depth from the skin surface.

Systems and methods for neuromodulation therapy are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, intravascularly positioning a plurality of ablation electrodes within a blood vessel lumen at a treatment site. The method can include analyzing a renal neuromodulation target site of a patient to obtain patient-specific data related to the renal neuromodulation target site, and based on the patient specific data, delivering neuromodulation treatment to the patient via one or more of the ablation electrodes.

Ablation systems and methods of the present disclosure control lesion depth and width such that, for example, wide and shallow lesions can be formed in target tissue in an anatomic structure of a patient during a medical procedure. Such wide and shallow lesions can be useful for treating, for example, thin tissue such as atrial tissue in atria of the heart of the patient.

A treatment of obstructive lung disease includes aiming a condensable vapor towards the airway wall, causing a band-shaped lesion to grow to a depth into the airway wall. Ablation parameters are set to control the depth of the band-shaped lesion to encompass the epithelial layer and exclude the smooth muscle layer of the airway. A wide variety of configurations of the vapor delivery are described to create ablation patterns in the airways of the patient with particular emphasis on treating chronic bronchitis.

An electrosurgical system includes an electrosurgical unit electrically coupled to a surgical retractor. The electrosurgical unit includes an RF output and an RF return. The surgical retractor includes a return pad electrically coupled to the RF return of the electrosurgical unit. The electrosurgical unit includes an RF output configured to be coupled to an electrosurgical device, such as an electrosurgical device configured in a monopolar mode. A controller is configured to determine an impedance in tissue at a surgical area electrically disposed between the RF output and the and the RF return. The surgical retractor includes a handle and a blade configured to interface with tissue. The blade includes a return electrode.

Various adaptive surgical visualization systems are disclosed. Surgical visualizations can compensate for obscured, incomplete, damaged, or interfered with portions of captured images by substituting those portions of the images with corresponding portions of other images. The other images could include images that were previously generated by the surgical visualization system or images that were generated using multispectral imaging techniques.

Ablation systems and methods of the present disclosure include a catheter including one or more image sensors. The one or more image sensors can facilitate, for example, positioning an ablation electrode at a treatment site of an anatomic structure and, additionally or alternatively, can facilitate controlling delivery of therapeutic energy to a treatment site of an anatomic structure.

Devices, systems, and methods of the present disclosure can overcome physical constraints associated with catheter introduction to facilitate the use of a catheter with a large distal portion as part of a medical procedure benefitting from such a large distal portion, such as, for example, cardiac ablation. More specifically, devices, systems, and methods of the present disclosure can compress an expandable tip of a catheter from an expanded state to a compressed state along a tapered surface of an insertion sleeve for advancement of the expandable tip into vasculature of a patient. The tapered surface of the insertion sleeve can, for example, apply compressive forces at an angle against the advancing expandable tip. As compared to other approaches to the application of compressive force to an expandable tip, compressing the expandable tip using an angled force can reduce the likelihood of unintended deformation of the expandable tip.

A surgical robot system comprising: a surgical robot, the surgical robot comprising a base, and an arm extending from the base to an attachment for an instrument the arm comprising a plurality of joints whereby the configuration of the arm can be altered; an instrument attached to the arm of the surgical robot; and a control unit configured to receive one or more inputs from an operator of the surgical robot in relation to movement of the instrument and translate the one or more inputs into one or more control signals in accordance with a set of control parameters to control the movement of the instrument, the set of control parameters being one of one or more sets of control parameters associated with the operator.
