摘要： A medical system includes a flexible catheter, an imaging probe, a working catheter, and a positioning system. The flexible catheter includes a plurality of first lumens and a sealing device having one or more balloons to seal the anatomic passageways at a sealing location and one or more flaps or valves to remove air from the anatomic passageways. The imaging probe and working catheter are receivable within the plurality of first lumens and extend through the sealing device. The working catheter includes one or more second lumens to receive a medical instrument. The positioning system is configured to determine a position of a distal portion of the flexible catheter, the imaging probe, or the working catheter. The medical system is configured to collapse a portion of the anatomic passageways distal of the sealing location by removing air from the anatomic passageways to facilitate ultrasound imaging using the imaging probe.

摘要： A method for controlling fluid delivery to a medical instrument comprises releasing, from a reservoir of a known size and having fluid at a volume and a first fluid pressure, a released fluid volume of the fluid to the medical instrument. The method also comprises measuring a vented fluid volume and determining a discharged fluid volume through the medical instrument based on the released fluid volume and the vented fluid volume.

摘要： Systems and methods for integrated real-time visualization while performing a minimally invasive procedure within anatomic passageways include a flexible catheter having one or more first lumens and a first positioning system, an imaging probe having one or more imaging elements, and a sealing device. In some embodiments, the sealing device includes a plurality of second lumens and the flexible catheter and the imaging probe are each optionally deployed through a respective one of the second lumens. In some embodiments, the one or more imaging elements include one or more ultrasound transducers. In some embodiments, the sealing device seals the anatomic passageways at a sealing location using one or more balloons, and the anatomic passageways distal to the sealing location are collapsed. In some embodiments, the first positioning system includes one or more position sensors. In some embodiments, the procedure is performed after the passageways are collapsed.

摘要： A medical system comprises an elongate device, an elongate sheath configured to extend within the elongate device, and an imaging probe configured to extend within the elongate sheath. The elongate sheath includes an identification feature. The medical system further comprises a control system configured to receive imaging data from the imaging probe. The imaging data is captured by the imaging probe. The control system is further configured to analyze the imaging data to identify an appearance of the identification feature within the imaging data. The control system is further configured to, based on the appearance of the identification feature, register the imaging data to a reference frame of the elongate device.

摘要： Flexible elongate device systems and methods include a flexible elongate device having a flexible body and an axial support structure. The axial support structure includes at least one groove extending along a length of the axial support structure. The flexible elongate device further includes a plurality of control elements for actuating the flexible elongate device. Each of the plurality of control elements extends through one of the at least one groove of the axial support structure. In some embodiments, the at least one groove includes a plurality of grooves spaced circumferentially around the axial support structure. In some embodiments, the flexible body includes lumens that extend through the at least one of the grooves. The control elements are disposed in the lumens. In some embodiments, the flexible body includes a main lumen that extends centrally through the flexible body. The main lumen provides a channel for a medical tool.
