A method and system to align a pin or drill a tunnel along a single line in space with a two degree of freedom (2-DOF) surgical device in a patient is provided. A plane is defined relative to a desired location for an implant or tunnel on a bone, where the implant or tunnel has an axis. An end-effector of the 2-DOF surgical device is aligned coincident with the plane, and the 2-DOF surgical device is moved side-to until a first indicator signals when the end-effector aligns with an entry point for the desired location for the implant or tunnel on the bone. A tip of the end-effector is anchored into the bone at the entry point; and the 2-DOF surgical device is rotated about the anchored tip until a second indicator signals when the end-effector aligns with the axis of the implant or tunnel at the desired location.

Disclosed herein are systems and techniques for compensating for insertion of an instrument into a working channel of another instrument in a surgical system. According to one embodiment, a method of compensation includes: detecting insertion of an insertable instrument into a working channel of a flexible instrument; detecting, based on a data signal from at least one sensor, a position change of a distal portion of the flexible instrument from an initial position: generating a control signal based on the detected position change; and adjusting a tensioning of a pull wire based on the control signal to return the distal portion to the initial position.

A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

Apparatus and methods for treating back pain are provided, in which an implantable stimulator is configured to communicate with an external control system, the implantable stimulator providing a neuromuscular electrical stimulation therapy designed to cause muscle contraction to rehabilitate the muscle, restore neural drive and restore spinal stability; the implantable stimulator further including one or more of a number of additional therapeutic modalities, including a module that provides analgesic stimulation; a module that monitors muscle performance and adjusts the muscle stimulation regime; and/or a module that provides longer term pain relief by selectively and repeatedly ablating nerve fibers. In an alternative embodiment, a standalone implantable RF ablation system is described.

Embodiments relate to surgical systems and methods. The system includes a main assembly having an IMU subsystem, camera, scope head assembly, and processor. Processor processes images and IMU information, including determining whether images include a distal end of the scope head assembly and a cannulation target. Responsive to a determination that images include the distal end of the scope head assembly, the processor generates 3-dimensional position of distal end of the scope head assembly. When images are determined to include the cannulation target, the processor generates 3-dimensional positions of the cannulation target. Processor also generates predictions of one or more real-time trajectory paths for the distal end of the scope head assembly to cannulate the cannulation target.

Systems and methods are described herein to generate a 3D surface scan of a surface profile of a patient's anatomy. The 3D surface scan may be generated by reflections of structured light off the surface profile of the anatomy. The 3D surface scan may be used during intra-operative surgical navigation by a localization system. Optionally, a pre-operative medical image may also be registered to the localization system or used to enhance the 3D surface scan.

Systems and methods for capturing and rendering light fields for head-mounted displays are disclosed. A mediated-reality visualization system includes a head-mounted display assembly comprising a frame configured to be mounted to a user's head and a display device coupled to the frame. An imaging assembly separate and spaced apart :from the head-mounted display assembly is configured to capture light-field data. A computing device in communication with the imaging assembly and the display device is configured to receive light-field data from the imaging assembly and render one or more virtual cameras. Images from the one or more virtual cameras are presented to a user via the display device.
