摘要： A catheterization system that includes an electrophysiologic (EP) catheter which has a lumen receiving an electrically conductive fluid delivered by a hydraulic line that is acted upon by a peristaltic pump advantageously avoids noise in intracardiac ECG signal recordings by using an electrical connection to short triboelectrical charge carried by the conductive fluid in the hydraulic line to an existing analog ground in the system. In one embodiment, the electrical connection includes an electrically conductive wire housed in the control handle and configured to provide electrical connection between the fluid and a pin on a printed circuit board housed in the control handle that is electrically connected to the analog ground. In another embodiment, the electrical connection shorts the electrically conductive fluid proximal of the control handle of the catheter.

摘要： An apparatus includes a shaft assembly, an end effector, and a sensor. The shaft assembly defines a longitudinal axis. The end effector is positioned at a distal end of the shaft assembly. A portion of the end effector is offset from the longitudinal axis. The sensor is configured to generate a signal in response to a magnetic field. The signal is configured to indicate a position of the end effector within three-dimensional space. The sensor is coaxially positioned about the longitudinal axis.

摘要： A method of treating a patulous Eustachian tube includes forming a first pocket in a wall of a nasopharynx region proximate to a pharyngeal ostium, inserting a resiliently biased implant within the first pocket, and allowing the resiliently biased implant to expand within the first pocket to thereby urge the Eustachian tube towards a closed state. The wire implant may include a resilient stent or other resilient wire structure. In some versions, a deployment device having a balloon is used to deploy a malleable implant. This deployment device has a malleable implant disposed around the balloon, which is disposed around a guide catheter. The balloon is inflated and expands the malleable implant. The malleable implant retains the expanded shape and urges the Eustachian tube toward a closed state.

摘要： A surgical instrument and method of tracking the surgical instrument includes a shaft, a cutting member, and navigation system. The shaft has a shaft lumen, a shaft window, and a shaft edge. The cutting member is disposed within the shaft lumen and is configured to cyclically move from a first position to a second position relative to the shaft. The cutting member includes a cutting window opening, a cutting edge, and a suction lumen to cut the tissue portion with the cutting member in the first position. The navigation system includes a navigation sensor positioned on at least one of the shaft or the cutting member that is configured to be tracked within a patient for identifying a positional movement of the shaft or the cutting member within the patient.

摘要： A dilation apparatus includes a handle assembly, a dilator, a guidewire, and a steering assembly. The dilator is connected to the handle assembly and is configured to transition between an unexpanded state and an expanded state. The guidewire is longitudinally fixed relative to the dilator. The steering assembly is configured to laterally deflect at least a portion of the guidewire relative to the handle assembly. The steering assembly includes an actuator coupled with the handle assembly and a pull wire extending between the actuator and guidewire. A portion of the pull wire is attached to the guidewire. The actuator is configured to move the pull wire relative to the handle assembly in order to laterally deflect the at least a portion of the guidewire.

摘要： An apparatus such as a suction instrument includes a position sensor proximate to a distal tip of a malleable shaft. A sensor wire couples the position sensor to a processor of an image guided surgery system such that signals generated by the position sensor can be interpreted to determine the position of the surgical instrument. The malleable shaft includes a malleable outer shaft and a flexible inner tube. The flexible inner tube includes a primary lumen that can provide suction, fluid, or various deployable surgical tools, and an inner lumen that holds the sensor wire. Protected within the inner lumen, the sensor wire runs the length of the shaft and exits the inner lumen and passes through a slot in the outer shaft to reach the position sensor. A heat shrink cover wraps the distal tip, sealing the components together and providing an opening suitable for suction.
