Dual coil ablation systems are provided. Methods of using the systems to ablate tissue are also provided. The dual coil ablation systems can include a first guide needle and a second guide needle, and the methods can include securing the tissue and guiding the dual coil ablation system into the tissue for the ablation, the securing and the guiding facilitated by the first guide needle and the second guide needle. The dual coil ablation systems can also include a phase-offset between the coils to achieve a significant and surprising enhancement to the energy density provided by the systems, and the uniformity of ablation provided by the methods.

A method comprises the steps of: imaging a patient anatomy; selecting an implant strategy for at least one bone fastener having a first member; registering the imaging of the patient anatomy with imaging of at least a portion of a robot; engaging the first member with tissue of the patient anatomy via robotic guidance according to the implant strategy; and subsequently, manipulating the patient anatomy. Systems, spinal constructs, implants and surgical instruments are disclosed.

Devices for transferring fluid to or from a subject include a plunger assembly coupled to or coupleable to a cannula assembly to allow target fluid to be “front-loaded” into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.

A percutaneous targeting device comprises a body holding an extension. The body has a target guide holding a target pin which may be a K-wire. The extension has two guide sleeves, holding a guide wire. All wires are held in a common plane. The guide wires serve as a guide for cannulated fixation screws. The extension is movable against the body to adjust the angle between the target pin and the guide wires.

A medical device and a method of using same are provided. The medical device includes a first arm and a second arm mounted on a support rail, each of the first arm and the second arm having a bone contacting region. The medical device also includes a mechanism for reducing a distance between the bone contacting regions hereby applying a force to a bone or bones positioned therebetween and a force gauge for indicating a force applied by the bone contacting regions.

A minimally invasive precision cutting guide, targeting guide, implant, and other instruments comprise a system that permits a physician to surgically correct a bunion or similar deformity with a minimum disruption of surrounding soft tissue. The precision cutting guide ensures that the physician cuts bone in the proper location and orientation. Each of the instruments is designed to minimize disruption to surrounding soft tissue. The system also precisely locates an orthopedic implant such that it can fixate two bone fragments after an osteotomy, or two bones after surgery. The precision cutting guide, targeting guide, implant, and other instruments are provided in a sterile kit for the convenience of the surgeon and safety of the patient.

A number of improvements are provided relating to computer aided surgery. The improvement relates to both the methods used during computer aided surgery and the devices used during such procedures. Some of the improvement relate to controlling the selection of which data to display during a procedure and/or how the data is displayed to aid the surgeon. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled automatically to improve the efficiency of the procedure. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure.

A computer-assisted teleoperated surgical system includes one or more manipulator devices and other components. A manipulator device includes a first link, a second link coupled to a distal end of the first link, a third link coupled to the second link, and an instrument actuator coupled to the third link. A joint that couples the second link to the first link defines a yaw axis. A joint that couples the third link to the second link defines a pitch axis. The instrument actuator defines an insertion axis. The yaw, pitch, and insertion axes are fixed in relation to each other and intersect at a remote center of motion. The instrument actuator may insert a surgical instrument along the insertion axis roll and may roll the surgical instrument around the insertion axis. The proximal end of the first link may be coupled to a repositionable setup structure, which may optionally be mechanically grounded to an operating room table. A user control unit includes a processor that acts as a controller, and user inputs at the user control unit teleoperated the manipulator device via the controller.
