    Abstract: A device a catheter includes a lumen extending therethrough, the catheter being sized and shaped to extend through an endoscopic shaft to a target tissue within a living body. The device also includes a puncturing device sized and shaped to extend through the lumen of the catheter and distally out a distal end of the catheter. The device further includes at least one of the catheter and the puncturing device including an electrode formed thereon. The electrode is energizable from a handle of the device so that, when the puncturing device is extended distally out the distal end of the catheter. The electrode may be energized as the device punctures the target tissue.

    Abstract: A medical system includes a plurality of tubes configured to be arranged about a periphery of an insertion device. A lumen of each of the plurality of tubes is configured to receive a medical device. Each of the tubes is configured to be coupled to the periphery of the insertion device and is moveable from a collapsed configuration adjacent the periphery of the insertion device to an expanded configuration further radially outward of the periphery of the insertion device as compared to the collapsed configuration.

    Abstract: A medical system may comprise a catheter (101) for ablating tissue including a flexible longitudinal body including a distal end; and a distal portion extending distally from the distal end of longitudinal body. The distal portion may include a plurality of electrodes (103). The medical system may also comprise one or more control units (112) coupled to the catheter and configured to (1) control a supply of electrical energy to each of the plurality of electrodes and (2) automatically control a position of the distal portion of the catheter.

    Abstract: A medical system having a medical tool, including a handle, a shaft extending from the handle and defining a lumen, a wire attached to and extending from the handle through the lumen, expandable elements at a distal end of the wire. An electrical generator is coupled to a proximal end of the wire and supplies a first waveform to the wire and the expandable elements as the expandable elements expand from an unexpanded state to an expanded state within a tissue. The electrical generator supplies a second waveform to the wire and the expandable elements when the expandable elements are in the expanded state within the tissue. The first waveform cuts tissue, the second waveform ablates tissue using radiofrequency ablation or irreversible electroporation.
