An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, “ultra-MIS” techniques.

The gear assembly including a gear rack provided on the driving member; and a main gear operatively connected with the gear rack, the motor spinning the main gear such that rotary motion of the main gear moves the driving member in an axial direction such that the driving member actuates the end effector to perform the surgical function.

Various surgical systems are disclosed. A surgical system can include a surgical robot and a surgical hub. The surgical robot can include a control unit in signal communication with a control console and a robotic tool. The surgical hub can include a display. The surgical hub can be in signal communication with the control unit. A facility can include a plurality of surgical hubs that communicate data from the surgical robots to a primary server. To alleviate bandwidth competition among the surgical hubs, the surgical hubs can include prioritization protocols for collecting, storing, and/or communicating data to the primary server.

A tissue suturing guidance system includes an image capturing device, a display, and a processor in communication with the image capturing device and the display. The image capturing device is configured to capture a suture site. The display is configured to display an image of the suture site. The processor is configured to: determine, based on the image of the suture site, a geometric tissue representation of the suture site; access measured properties of the suture site; determine, based on the measured properties of the suture site, a biomechanical tissue representation of the suture site; and generate, based on the geometric tissue representation and biomechanical tissue representation of the suture site, a suturing configuration for the suture site.

A generator, ultrasonic device, and method for controlling a temperature of an ultrasonic blade are disclosed. A control circuit coupled to a memory determines an actual resonant frequency of an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade by an ultrasonic waveguide. The actual resonant frequency is correlated to an actual temperature of the ultrasonic blade. The control circuit retrieves from the memory a reference resonant frequency of the ultrasonic electromechanical system. The reference resonant frequency is correlated to a reference temperature of the ultrasonic blade. The control circuit then infers the temperature of the ultrasonic blade based on the difference between the actual resonant frequency and the reference resonant frequency. The control circuit controls the temperature of the ultrasonic blade based on the inferred temperature.

An ultrasonic device may include an electromechanical system defined by a resonant frequency and further include an ultrasonic transducer coupled to an ultrasonic blade. The device may be composed of two or more components, one of which is reusable and one of which is disposable. A method of detecting a proper installation of the components may include determining a spectroscopy signature of the blade coupled to the transducer, comparing the signature to a reference signature, determining an installation state of the components based on the comparison, and controlling a delivery of power to the transducer based on the comparison. The method may include enabling an operation of the device when the installation state of components is proper. The method may further include disabling the device when the installation state is not proper and generating a warning. The warning may be visible, audible, or tactile.

Disclosed are methods and devices for obtaining patent hemostasis of the radial artery by compressing the ipsilateral ulnar artery to increase radial artery flow. Also disclosed are methods, devices and system for minimizing radial artery occlusion when performing complex PCI procedure using transradial access and transradial catheterization using a large bore sheath. The device comprises a band having at least two inflatable bladders, at least one inflatable bladder used for applying pressure to the radial artery. and at least one inflatable bladder used for applying pressure to the ipsilateral ulnar artery.

A device is disclosed for occluding an anatomical passage between first and second anatomical structures. The device includes a tip portion having a proximal element connected to a distal element through a member. The proximal element and/or distal element is movable axially along the tip portion while the other element preferably remains fixed in place. A handle is coupled to a proximal end of the tip portion through a shaft. The tip portion is positioned across the anatomical passage so that the proximal element occludes a first side of the passage and the distal element occludes a second side of the passage. A locking structure, such as a nut, is positioned or crimped against the proximal element, and, once done, the tip portion is released at the occluded passage.

Methods for treating hypertension and associated systems and methods are disclosed herein. One aspect of the present technology, for example, is directed to methods for therapeutic renal neuromodulation that partially inhibit sympathetic neural activity in renal nerves proximate a renal blood vessel of a human patient having a 24-hour heart rate at or above a median heart rate for a population of hypertensive patients. This reduction in sympathetic neural activity is expected to therapeutically treat one or more conditions associated with hypertension of the patient. Renal sympathetic nerve activity can be modulated, for example, using an intravascularly positioned catheter carrying a neuromodulation assembly, e.g., a neuromodulation assembly configured to use electrically-induced, thermally-induced, and/or chemically-induced approaches to modulate the renal nerves.

Aspects of embodiments pertain to an intraoperative ophthalmic tissue monitoring system, comprising at least one sensor configured to sense a physical quantity relating to an ophthalmic tissue characteristic of an eye. The system is further configured to provide, responsive to sensing the physical quantity, a sensor output relating to the sensed physical quantity. The system additionally comprises a processor, and a memory comprising for storing software executable by the processor for enabling the following: controlling, based on the sensor output, a characteristic of ultrasound energy for performing phacoemulsification of a lens of the eye.
