摘要： Systems and methods of in situ unclogging a working channel in a medical device during a procedure are disclosed. An exemplary unclogging system comprises a flow sensor to sense a flow rate through a working channel, and a control module to detect a channel state indicating a presence or absence of clogging based on the flow rate. In the presence of channel clogging, the control module can control one or more of an irrigation source or a suction source to provide respectively irrigation fluid or suction pressure to unclog the obstructed channel. The control module can adjust one or more of an irrigation flow rate or a suction flow rate through the working channel to maintain a desired pressure of the anatomical environment at the anatomical site, or to maintain a desired flow condition in the working channel, during the procedure.

摘要： An apparatus includes a catheter shaft assembly and an end effector positioned at a distal end of the catheter shaft assembly. The end effector includes a balloon, one or more electrodes on the balloon, and a tip assembly at a distal end of the balloon. The balloon defines an interior configured to receive a fluid to inflate the balloon. The balloon is sized and configured to fit within a cardiovascular anatomical structure. The tip assembly includes a pressure relief valve that is configured to transition between a sealing state and a pressure-relieving state. In the sealing state, the pressure relief valve is configured to prevent fluid from leaking out from the interior of the balloon via the pressure relief valve. In the pressure-relieving state, the pressure relief valve is configured to provide a path for fluid to leak from the interior of the balloon via the pressure relief valve.

摘要： A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector disposed at a distal end of the shaft, an actuator operably coupled to the housing, an actuation assembly, and a sensor module. The actuation assembly extends through the housing and the shaft and includes a distal end operably coupled to the end effector or a component associated therewith, a proximal end operably coupled to the actuator, and a spring. Actuation of the actuator manipulates the end effector or deploys the component relative thereto. The sensor module is disposed within the housing and configured to sense a property of the spring indicative of an amount the spring has been compressed. The sensor module is further configured, based upon the sensed property, to determine a condition of the end effector or the relative position of the component.

摘要： Devices and methods for monitoring the temperature of tissue at various locations in a treatment volume during fluid enhanced ablation therapy are provided. In one embodiment, an ablation device is provided having an elongate body, at least one ablation element, and at least one temperature sensor. The elongate body includes a proximal and distal end, an inner lumen, and at least one outlet port to allow fluid to be delivered to tissue surrounding the elongate body. The at least one ablation element is configured to heat tissue surrounding the at least one ablation element. The at least one temperature sensor can be positioned a distance away from the at least one ablation element and can be effective to output a measured temperature of tissue spaced a distance apart from the at least one ablation element such that the measured temperature indicates whether tissue is being heating to a therapeutic level.

摘要： Systems and methods for assessing sympathetic nervous system (SNS) tone for renal neuromodulation therapy are disclosed herein. A system configured in accordance with embodiments of the present technology can include, for example, a detector attached to or implanted in a patient and a receiver communicatively coupled to the detector. The detector can measure cardiac data and the receiver and/or a device communicatively coupled thereto can analyze the cardiac data to provide one or more SNS tone indicators. The SNS tone indicators can be used to determine whether a patient will be responsive to a neuromodulation therapy and/or whether a neuromodulation therapy was effective.

摘要： A catheter enables real-time light measurements, for example, without limitation, diffuse reflectance, fluorescence, etc., from biological materials, such as tissue (including blood), while performing RF ablation. The catheter tip design isolates illumination and collection paths within the tip electrode such that light for illuminating the tissue of interest (e.g., cardiac tissue or blood) is isolated within the tip electrode from light that returns from the tissue to the catheter tip, and vice versa. Such a design advantageously avoids saturation of the optical detector, and ensures diffusion of the illumination light within the medium of interest. The catheter has a catheter body and a tip electrode with a shell wall and a hollow cavity. The shell wall has at least an illumination opening and a collection opening. The catheter further includes a first fiber optic cable in communication with the illumination opening, and a second fiber optic cable in communication with the hollow cavity, wherein light emitted from the first fiber optic cable exits the tip electrode to reach tissue through the illumination opening in defining a first path and returns to the tip electrode from the tissue into the hollow cavity through the collection opening in defining a second path, the first and second paths being optically isolated from each other within the tip electrode. The invention also includes a method of making an ablation electrode tip defining isolated optical paths with in the tip electrode for light exiting the tip electrode and light returning to the tip electrode.
