A modular energy system including a header module configured to removably connect to an energy module. The energy module can comprise a port configured to deliver one or more energy modalities to a surgical instrument connected thereto. The header module can comprise a display screen configured to display a user interface. The header module can further include a control circuit configured to detect attachment of energy modules to the modular energy system and control the display of the user interface to display UI portions for each connected module and reconfigure the displayed UI portions to accommodate the new UI portions as additional energy modules are connected to the modular energy system.

An ultrasonic surgical tool system with a tip capable of simultaneously vibrating in plural modes. The system includes a console capable of supplying a drive signal to the tip that includes plural components. Each component has a frequency characteristic that is based in part on the equivalent of current through the mechanical components of the tip. The frequency components are different from each other. Based on the application of drive signal the tip undergoes non-linear vibrations.

An apparatus includes a body, a shaft assembly, and an end effector. The shaft assembly includes an outer tube, an inner tube, and an acoustic waveguide. The end effector includes an ultrasonic blade and a clamp arm. The ultrasonic blade is acoustically coupled with the acoustic waveguide. A first portion of the clamp arm is pivotably coupled with a distal end of the outer tube. A second portion of the clamp arm is pivotably coupled with a distal end of the inner tube. The outer tube and the inner tube are configured to removably couple with the body such that the outer tube, the inner tube, and the clamp arm are configured to removably couple with the body and the remainder of the shaft assembly and end effector as a unit.

An ultrasonic surgical instrument includes a body, an ultrasonic supported by the body, a shaft extending distally from the body and defining a shaft axis, a waveguide extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade coupled to a distal end of the waveguide and having a primary blade treatment surface configured to treat tissue, and a clamp arm coupled to the distal end of the shaft. The shaft and the waveguide are selectively rotatable relative to one another about the shaft axis through a predefined range of angular motion between an assembly state and an operational state. In the assembly state, the clamp arm and the primary blade treatment surface are rotationally offset from one another. In the operational state, the clamp arm and the primary blade treatment surface are rotationally aligned.

An ultrasonic surgical instrument includes a handpiece casing and an electromechanical transducer assembly disposed inside the handpiece casing, where the transducer assembly includes a front driver and the transducer assembly has a longitudinal axis. A probe is operatively connected to the front driver at an acute angle to the longitudinal axis of the transducer assembly. A sheath surrounds the probe and is connected at a proximal end to the handpiece casing. The sheath is attached to the casing by a twist quick release coupling. A diaphragm seal inside the proximal end of the sheath blocks liquid irrigant in a cylindrical space between the sheath and the probe from penetrating proximally of a port feeding irrigant to the space. The front driver is geometrically configured to enable an angled connection of probe to handpiece proximate a nodal plane.

An ultrasonic surgical blade includes a body having a proximal end, a distal end, and an outer surface. The distal end is movable relative to a longitudinal axis in accordance with ultrasonic vibrations applied to the proximal end. At least a portion of the outer surface of the body comprises a lubricious coating adhered thereto. The lubricious coating has a coefficient of friction that is less than the coefficient of friction of the outer surface of the body.

A surgical instrument is disclosed including a transducer, an ultrasonic blade, a protective sheath, and a non-vibrating clamp arm assembly. The ultrasonic blade extends along the longitudinal axis coupled to the transducer. The ultrasonic blade comprises a body having a proximal end and a distal end. The distal end is movable along the longitudinal axis by vibrations produced by the transducer. The protective sheath comprises a proximal end and a distal end and disposed adjacent to the body. The protective sheath further comprises a pad positioned toward the distal end of the protective sheath and located between the body and the distal end of the protective sheath. The non-vibrating clamp arm assembly has a proximal end and a distal end and pivotally positioned adjacent to the body. The clamp arm assembly is pivotally moveable from an open position to a closed position.

A system for creating an arteriovenous (AV) fistula comprises a vessel access sheath having a hollow interior and an exit port, a side access needle catheter configured to fit within the hollow interior of the sheath, a needle configured to be inserted into a blood vessel through the side access needle catheter, a toggle delivery catheter configured to fit within the hollow interior of the sheath, and a toggle apparatus configured to be delivered into a vessel through the toggle delivery catheter. The toggle apparatus comprises a shaft and a toggle member pivotably attached to a distal end of the shaft. A source of RF energy or resistive heat energy may be provided for application to the toggle member and/or to a heater insert in the toggle delivery catheter, for the purpose of creating the fistula.

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).

An apparatus comprises an electrically power surgical instrument having a handle assembly. The apparatus also comprises a communication device positioned within the handle assembly. The communication device is operable to communicate with at least a portion of the electrically powered surgical instrument. The apparatus further comprises an external device in wireless communication with the communication device. The external device is operable to receive information from the communication device and the external device is operable to provide an output viewable to the user.
