Abstract: The present invention is a minimally invasive articulating configured to be advanced through tortuous anatomy, particularly within a lung, and subsequently deliver at least two separately deployable ablation devices to a target site located at a bifurcated section of the lung (i.e., at a bronchial airway bifurcation). The pair of ablation devices are separately steerable towards respective first and second pathways extending from the bifurcation, such that each of the ablation devices can be positioned on either side of a target tissue proximate the bifurcation. The first and second ablation devices include expandable distal tips configured to transition to a deployed configuration, in which each expands in diameter and is configured to apply a degree of compression and/or RF energy emission to target lung tissue (i.e., diseased tissue, such as cancer or emphysema-related damaged tissue) for subsequent ablation thereof.

Abstract: The invention generally relates to a tissue ablation system including an ablation device to be delivered to a target site and achieve both resection and coagulation of tissue. The ablation device can be used during an electrosurgical resection procedure to both resect tissue and further selectively coagulate surrounding tissue in the resection site so as to prevent or stop fluid accumulation (e.g., blood from vessel(s)) as a result of the resection of tissue.

Abstract: The invention is an accessory configured to be fitted to an electrical surgical device and provide suction at a surgical site in which the electrical surgical device is being used. In particular, the accessory is in the form of a suction collar configured to be releasably coupled to the electrical surgical device, generally adjacent to a working end thereof, and provide suction to minimize the accumulation of excess steam, fluid, and/or debris from the surgical site during the treatment procedure. The suction collar is further configured to apply a sufficient suction force to a patient's skin surrounding the surgical site to aid in stabilizing the electrosurgical device in place and maintain the working end to the electrosurgical device within the surgical site during the procedure.

Abstract: The present invention relates to an electrosurgical system including an electrosurgical device to be delivered to a wound site to provide chronic wound treatment. The device can be used during a wound care procedure to provide targeted energy at a wound site for reducing the accumulation of biofilm present and removing necrotic tissue and debris so as to promote, stimulate, and stabilize the wound healing process. The device can further be used during a surgical procedure, such as preparation for an orthopedic implant, in which the device is configured to selectively coagulate one or more pockets prepared within bone tissue for holding an implant so as to prevent or stop fluid accumulation (e.g., blood from vessel(s)) as a result of the implant preparation.

Abstract: The invention is a tissue ablation system including an ablation device having an electrode array configured for the ablation of tissue, wherein the electrode array includes a plurality of conductive wires electrically isolated and independent from one another and configured to receive electrical current from a source and emit radiofrequency (RF) energy in response. The ablation system further includes a controller configured to control an emission pattern from the electrode array, either by independently controlling activation of one or more conductive wires or by actively blocking emission of energy from a selected one or more conductive wires or by adjusting flow of a conductive fluid for carrying RF energy emitted in a virtual electrode arrangement. Accordingly, the system provides a user with custom ablation shaping including custom, user-defined ablation geometries or profiles for RF emission in a desired shape or pattern so as to deliver targeted treatment to marginal tissue.
