A method includes, receiving multiple signals from multiple respective electrodes arranged along an inner circumference of a blood vessel that has been ablated. Based on the multiple signals, one or more quality measures of the ablated blood vessel are produced. A graphical presentation indicative of the one or more quality measures, is displayed to a user in a two-dimensional (2D) polar coordinate system.

An apparatus includes a shaft assembly, an end effector, and a drive member visualization assembly. The end effector includes a first jaw, a second jaw, a staple cartridge, and a drive member capable of actuating along a firing stroke to fire a plurality of staples out of the staple cartridge or to sever tissue. The drive member visualization assembly provides an electronic indication linked to a physical location of the drive member within the upper jaw and the lower jaw during the firing stroke.

A method for performing a procedure on a patient includes acquiring a three-dimensional image of a location of interest on the patient and a two-dimensional image of the location of interest can be acquired. A computer system can relate the three-dimensional image with the two-dimensional image to form a holographic image dataset. The computer system can register the holographic image dataset with the patient. The augmented reality system can render a hologram based on the holographic image dataset from the patient. The hologram can include a projection of the three-dimensional image and a projection of the two-dimensional image. The practitioner can view the hologram with the augmented reality system and perform the procedure on the patient. The practitioner can employ the augmented reality system to visualize a point on the projection of the three-dimensional image and a corresponding point on the projection of the two-dimensional image during the procedure.

A medical device navigation system includes a medical device assembly and a navigation device. The medical device assembly includes an adhesive patch configured to adhere to an outer surface of a patient and a tracking assembly coupled to the adhesive patch. The tracking assembly includes one or more reference markers. The navigation device is configured to receive image data representing one or more images from an imaging device. The one or more images indicate a relative position between the one or more reference markers and a treatment site in the patient. The navigation device is configured to determine, based on the image data, a percutaneous insertion path for an injection needle from an insertion point to the treatment site of the patient and output one or more parameters corresponding to the percutaneous insertion path.

Devices, systems, and methods for localized delivery of a chemotherapy, hormonal therapy, or targeted drug/biologic therapy to a target tissue area of an internal body organ of a patient. Computer systems may be used for planning and navigation in super selective drug delivery via a tracheobronchial airway. A catheter may be used to form a sealed treatment chamber in a natural lumen extending through the target tissue area. Air is purged from the chamber, which is then filled with a liquid drug solution for an adequate treatment session time, solution volume and drug concentration to saturate the target tissue area, thereby providing the treatment. The liquid drug solution may be circulated or recirculated through the chamber or maintained stationary therewithin to saturate the target tissue area. The chamber is evacuated at the end of the treatment session.

A robotic system includes an instrument including an elongate shaft, a robotic manipulator configured to manipulate the elongate shaft of the instrument, and control circuitry communicatively coupled to the robotic manipulator and configured to determine a first estimated position of at least a portion of the elongate shaft of the instrument based at least in part on robotic command data, determine a second estimated position of the at least a portion of the elongate shaft of the instrument based at least in part on position sensor data, compare the first estimated position and the second estimated position, and generate a third estimated position based at least in part on the comparison of the first estimated position to the second estimated position.

A vapor delivery system is provided that may include any of a number of features. One feature of the vapor delivery system is that it can apply condensable vapor energy to tissue, such as a prostrate, to shrink, damage, or denature the prostate. In some embodiments, the vapor delivery system can include safety features including prostate capsule detection, needle tracking, and treatment tracking. Methods for safe and effective treatment of prostate tissues are presented.

Systems and methods for electroporation are provided. An electroporation system includes a catheter including a plurality of electrodes, and a pulse generator coupled to the catheter, the pulse generator configured to generate a waveform to be delivered using at least one of the plurality of electrodes. The waveform includes a first pulse having a first polarity, a first pulse amplitude, and a first pulse width, and a second pulse having a second polarity, a second pulse amplitude, and a second pulse width, wherein the first and second pulses are separated by an interpulse delay, and wherein at least one of i) the first pulse amplitude is different than the second pulse amplitude and ii) the first pulse width is different than the second pulse width.

A tracking apparatus for tracking a bone of a patient limb is provided. The tracking apparatus includes a body configured to couple to the patient limb. The body includes first and second arms each including an exterior and opposing interior surface and opposing sides connecting the exterior and interior surfaces. The tracking apparatus also includes a wing portion extending from one of the sides of the first or second arm, the wing portion sharing the interior surface of the first or second arm. The tracking apparatus also includes one or more ultrasonic sensors coupled to the interior surface of the body and the interior surface of wing portion, the one or more ultrasonic sensor being configured to transmit ultrasonic waves to and receive ultrasonic waves from the bone. The tracking apparatus also includes one or more trackable elements coupled to the body and the wing portion.

The present disclosure relates to systems that comprise a millimeter size tetherless object powered by an external magnetic field, and an interactive hardware-software platform separate from the miniature device that generates, modulates and controls magnetic fields in a defined three-dimensional operational volume to propel, navigate the miniature device to a specific anatomical target to complete a (microsurgical) mission or task, as well as using such systems to perform microsurgery in the central nervous system (CNS).
