摘要: A system may include an elongate flexible device, a flexible instrument, and a processor. The elongate flexible device may include a first shape sensor configured to generate first shape data corresponding to a shape of the elongate flexible device. The flexible instrument may include a second shape sensor configured to generate second shape data corresponding to a shape of the flexible instrument. The processor may be configured to register the flexible instrument to the elongate flexible device based on the first shape data and the second shape data. The first shape data and the second shape data may be generated while the flexible instrument is mated with the elongate flexible device.

摘要: Approaches to addressing asymmetric loads at the distal end of a flexible elongate device are disclosed herein. In some embodiments, symmetry is recovered by mechanically redesigning the flexible elongate device to counter the asymmetric load. In other embodiments, symmetry is recovered by altering the controls scheme for managing the control elements in a flexible elongate device. Generally, a flexible elongate device includes a plurality of control elements able to actuate the distal section. The amount of force applied to each control element can be changed so that the plurality of control elements is able to collectively apply a bending moment that counters the asymmetric load.

摘要: A system may comprise a sensing instrument including an elongate flexible member with a channel extending therein. The elongate flexible member may include a proximal portion, a distal portion, and a flexure portion between the distal and proximal portions. The sensing instrument may also include a flexure at the flexure portion of the elongate flexible member, a sensing element coupled at the distal portion of the elongate flexible member, and a flexure control apparatus extending within the elongate flexible member and configured to bend the flexure to change an orientation of the sensing element relative to the proximal portion of the elongate flexible member. The sensing instrument may also include an exit port in the proximal portion of the elongate flexible member.

摘要: An energy delivery system and methods for an ablation procedure may include a generator configured to generate an electrical signal having an operating frequency for an ablation operation and an ablation probe coupled to the generator and configured to receive the electrical signal from the generator. The ablation probe may include a flexible body portion including an inner conductor, an outer conductor, and a dielectric between the inner and outer conductors. The ablation probe may further include a radiating portion electrically coupled to the inner conductor, where the radiating portion is configured to radiate energy received from the electrical signal. A length of the radiating portion may be between 0.35 and 0.65 times an operating wavelength, where the operating wavelength is dependent on the operating frequency of the electrical signal.

摘要: A system may comprise an elongate flexible instrument including an imaging device disposed at a distal end portion of the elongate flexible instrument. The imaging device may include a multi-directional imaging array. The elongate flexible instrument may also include a localization sensor extending within the elongate flexible instrument. The system may also comprise a controller comprising one or more processors configured to register the localization sensor to a patient anatomy and receive orientation data for the distal end portion of the elongate flexible instrument from the localization sensor. Based on the orientation data, an imaging plane of the imaging device may be selected. An image in the selected imaging plane may be displayed. The image may be generated by imaging data from the multi-directional imaging array of the imaging device.

摘要: A system may comprise an elongated tool through which a lumen extends and may comprise a stylet including an expandable electrode portion. The expandable electrode portion may have a collapsed configuration within the lumen and may have an expanded configuration outside of the lumen. A diameter of the expandable electrode portion may be larger in the expanded configuration than the collapsed configuration. In the expanded configuration, the expandable electrode portion may be configured to create a plurality of path segments in a target tissue. Each path segment in the plurality of path segments may be extended in a different direction. The expandable electrode portion in the expanded configuration may be configured to deliver energy to ablate the target tissue.
