An object sizing system sizes an object positioned within an anatomical feature. The object sizing system navigates an elongate body to a location within an anatomical feature and proximate to the object. An imaging sensor coupled to the elongate body captures images of the object. The object sizing system captures the object with a basket. The object sizing system captures an image of the object with the imaging sensor. The object sizing system detects a basket marker in the captured image. The object sizing system determines a distance from the object to the imaging sensor based on the detected basket marker. The object sizing system determines an estimated size of the object based at least in part on the distance.

A robotic system for cochlear implantation (CI) is described herein. The system includes a robotic tool configured to hold a cochlear implant electrode array and a controller that is operably coupled to the robotic tool. The controller includes a processor and a memory. The memory has computer-executable instructions stored thereon that, when executed by the processor, cause the processor to control the robotic tool with the degrees of freedom of a human hand.

Devices, systems, methods, and computer program products for performing medical procedures are disclosed herein. In some embodiments, a system for planning a medical procedure is configured to receive a three-dimensional (3D) model of an anatomic region of a patient. The 3D model can include a set of linked structures and at least one isolated structure spaced apart from the linked structure. The system can output a graphical representation of the linked structures and the at least one isolated structure, and can receive operator input indicating a set of locations on the graphical representation. The set of locations can represent a connection between the at least one isolated structure and the linked structures. Based on the operator input, the system can generate a bridge structure connecting the at least one isolated structure to the linked structures.

Flexible robotic systems are provided for guidance and to facilitate reliable suturing within the gastrointestinal tract. Such robotic systems provide assistance, assurance, and/or validation to compensate for the level of skill and experience of the operator, and to expedite completion of bariatric procedures approached from within the stomach.

A surgical image acquisition system includes multiple illumination sources, each source emitting light at a specified wavelength, a light sensor to receive light reflected from a tissue sample illuminated by each of the illumination sources, and a computing system. The computing system may receive data from the light sensor when the tissue sample is illuminated by the illumination sources, and calculate structural data related to one or more characteristics of a structure within the tissue. The structural data may be a surface characteristic such as a surface roughness or a structure composition such as a collagen and elastin composition. The computer system may further transmit the structural data to a smart surgical device. The smart devices may include a smart stapler, a smart RF sealing device, or a smart ultrasonic cutting device. The system may include a controller and computer enabled instructions to accomplish the above.

The present invention relates to a visualization system disposed in a human body, including, a nanobot configured to be disposed within the human body, the nanobot having at least one embedded biosensor, the biosensor which operates in real-time to continuously obtain data from within the human body; a visualization device configured to be integrated and/or embedded within the nanobot to provide real-time visualization data in the human body; a transmitter/receiver disposed on the nanobot which transmits data from the nanobot to an external transmitter/receiver, the transmitted data including the data from the biosensor and the data from the visualization device; and a processor configured to receive the data from the external transmitter/receiver of the nanobot and analyze the visualization data to determine the anatomic localization of the nanobot at a specific anatomic position within the human body.

Certain aspects relate to systems and techniques for driving a medical instrument having an inner body and an outer body. In one aspect, a system includes a medical instrument comprising an outer body and an inner body configured to be driven through a lumen in the outer body. The system may further include a set of one or more instrument manipulators configured to control movement of the outer and inner bodies and a set of one or more processors configured to: receive a change drive mode command, and in response to receiving the change drive mode command, change a drive mode of the medical instrument from a paired drive mode to an unpaired drive mode.

A method comprises identifying linked anatomical structures in stored images of a patient anatomy and modeling a structure of linkage elements. Each linkage element corresponds to one of the linked anatomical structures. The method also includes modeling a portion of the patient anatomy as a plurality of search slabs and assigning each of the linkage elements to one of the plurality of search slabs. The method also includes receiving tracking data corresponding to a sensed instrument portion. The tracking data includes position information and orientation information for the sensed instrument portion. The method also includes identifying one of the plurality of search slabs which includes the position information for the sensed instrument portion and matching the sensed instrument portion to a matched linkage element from among the linkage elements assigned to the identified one of the plurality of search slabs.

The apparatus of one embodiment of the present invention is comprised of a flexible sheath instrument, a flexible guide instrument, and a tool. The flexible sheath instrument comprises a first instrument base removably coupleable to an instrument driver and defines a sheath instrument working lumen. The flexible guide instrument comprises a second instrument base removably coupleable to the instrument driver and is threaded through the sheath instrument working lumen. The guide instrument also defines a guide instrument working lumen. The tool is threaded through the guide instrument working lumen. For this embodiment of the apparatus, the sheath instrument and guide instrument are independently controllable relative to each other.

A medical robotic system includes an entry guide with surgical tools and a camera extending out of its distal end. To supplement the view provided by an image captured by the camera, an auxiliary view including articulatable arms of the surgical tools and/or camera is generated from sensed or otherwise determined information about their positions and orientations are displayed along with indications of range of motion limitations on a display screen from the perspective of a specified viewing point.
