The disclosure provides for an isovolumetric pump system for the removal of a thrombus and a method of use thereof. The isovolumetric pump system includes at least one inflow container connected to an output of the treatment region, at least one outflow container connected to an input of the treatment region, and a drawbar connecting the inflow container and the outflow container. As the drawbar is drawn back, the same quantity of fluid is drawn from the treatment region into the inflow container and injected into the treatment region from the outflow container.

An apparatus includes an end effector and a drive system. The drive system is configured to drive a jaw closure assembly to provide the end effector in a first closed position. The drive system is further configured to operatively disengage the jaw closure assembly and operatively engage a firing assembly, then distally advance a firing member to actuate the end effector. The drive system is further configured to detect an initiation condition; and in response to detecting the initiation condition, operatively disengage the firing assembly and operatively re-engage the jaw closure assembly. The drive system is further configured to drive the jaw closure assembly to provide the end effector in a second closed position, then operatively disengage the jaw closure assembly and operatively re-engage the firing assembly. The drive system is further configured to distally advance the firing member further within the end effector to further actuate the end effector.

A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.

A method of displaying an operational parameter of a surgical system is disclosed. The method includes receiving, by a cloud computing system of the surgical system, first usage data, from a first subset of surgical hubs of the surgical system; receiving, by the cloud computing system, second usage data, from a second subset of surgical hubs of the surgical system; analyzing, by the cloud computing system, the first and the second usage data to correlate the first and the second usage data with surgical outcome data; determining, by the cloud computing system, based on the correlation, a recommended medical resource usage configuration; and displaying, on respective displays on the first and the second subset of surgical hubs, indications of the recommended medical resource usage configuration.

A stimulation device includes an adapter component to increase the usability of the stimulation device. The adapter may be a bipolar adapter arranged to connect to the housing of the stimulation device. The adapter may include a clip having a first channel configured to receive an operative element therein and a second channel having a return operative element therein. The return operative element is in electrical communication with an electrical circuit of said stimulation control device. Alternatively, the adapter may be a percutaneous adapter comprising a connector configured to connect to an operative element of a stimulation device and a lead wire connected to the connector. A needle may be connected to the lead wire to deliver a electrical stimulation signal to a target tissue located beneath the skin of a subject patient.

Aspects of embodiments pertain to a perineal protection device for reducing the risk or preventing perineal tear during birth. The device may comprise a reinforcement shield that is releasably connectable to a female perineum of a subject, the reinforcement shield having a surface geometry substantially corresponding to an underlying perineal muscle structure and being configured to reduce deformation of the perineum during childbirth. Optionally, the perineal protection device further comprises a fastener arrangement for releasably securing the reinforcement shield to the female perineum. The fastener arrangement may comprise a support pad that is adhesively engageable with the subject and/or straps for strapping the reinforcement shield to the subject.

A surgical stapling apparatus includes an end effector and an electronics assembly, the end effector having an anvil assembly and a cartridge assembly. The anvil and cartridge assemblies are positionable between an open position and a closed position to selectively grasp tissue therebetween. The electronics assembly is supported in the end effector and configured to determine a condition of the grasped tissue based on an amount of current in an electrical circuit defined by the anvil and cartridge assemblies.

A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

Various systems and methods for controlling the activation of energy surgical instruments are disclosed. An advance energy surgical instrument, such an electrosurgical instrument or an ultrasonic surgical instrument, can include one or more sensor assemblies for detecting the state or position of the end effector, arm, or other components of the surgical instrument. A control circuit can be configured to control the activation of the surgical instrument according to the state or position of the components of the surgical instrument.

An ultrasonic device may include an electromechanical ultrasonic system defined by a predetermined resonant frequency, in which the system may include an ultrasonic transducer coupled to an ultrasonic blade. A method of estimating a state of an end effector of the ultrasonic device may include applying a drive signal defined by a magnitude and a frequency to the ultrasonic transducer, sweeping the frequency of the drive signal from below a first resonance to above the first resonance of the electromagnetic ultrasonic system, measuring and recording, impedance/admittance circle variables R.sub.e, G.sub.e, X.sub.e, and B.sub.e, comparing, the measured impedance/admittance circle variables R.sub.e, G.sub.e, X.sub.e, and B.sub.e to reference impedance/admittance circle variables R.sub.ref, G.sub.ref, X.sub.ref, and B.sub.ref, and determining, a state or condition of the end effector based on the result of the comparison. An electromechanical ultrasonic system may include a control circuit to effect the method.
