The device also includes an adapter assembly configured to selectively couple to the handle assembly, the adapter assembly including a stapling transmission assembly movable by the motor. The device also includes a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including a plurality of staples ejectable from the reload by the stapling transmission assembly. The device also includes an anvil assembly selectively couplable to the distal portion of the adapter assembly, the anvil assembly being movable relative to the reload, where the controller may be further configured to control the motor to move the stapling transmission assembly to eject the staples while compensating for mechanical losses of the stapling transmission assembly.
A system and method for enhanced surgical navigation and graphical user interfaces associated therewith. The system includes a 3D endoscope and a computing device including a display for displaying the graphical user interfaces. The 3D endoscope includes a camera source and a scan source and is utilized to generate a 3D spatial map of a surgical site. A position of a surgical tool is detected in the 3D spatial map, a distance between the position of the surgical tool in the 3D spatial map and a location of an anatomy is detected, and a warning is generated when it is determined that the distance between the position of the surgical tool in the 3D spatial map and the location of the anatomy is equal to or not greater than a threshold minimum distance.

PHYSIOLOGICAL MONITORING METHODS AND SYSTEMS UTILIZING DISTRIBUTED ALGORITHMS
Systems and methods are provided for operating a physiological monitoring system that comprises a distributed algorithm. The physiological monitoring system may comprise a sensor and a physiological monitor that may be communicatively coupled with the sensor. The sensor may store algorithm configuration data; and the physiological monitor may store an executable code segment configured to execute a first algorithm. The physiological monitor may be configured to receive the algorithm configuration data and to configure or modify at least part of the first algorithm based upon the algorithm configuration data to determine at least one physiological parameter of a subject based on physiological signal provided by the sensor.
A61B 5/1455 - Measuring characteristics of blood in vivo, e.g. gas concentration, pH-value using optical sensors, e.g. spectral photometrical oximeters

ROBOTICALLY AND MANUALLY OPERABLE UTERINE MANIPULATORS
A uterine manipulator includes a housing configured to be coupled to an instrument drive unit of a robotic system, a shaft extending distally from the housing, a tip hub pivotably coupled to a distal end portion of the shaft, an articulation disposed within the housing, and a handle operably coupled to either the housing or the shaft. The articulation assembly is configured to pivot the tip hub relative to the shaft and includes a drive cable operably coupled to the tip hub. The articulation assembly is actuatable manually by a user and robotically by the robotic system to pivot the tip hub relative to the shaft. The handle is configured to be manually gripped by a user for manual use of the uterine manipulator
A method for treating an aneurysm in accordance with a particular embodiment of the present technology includes intravascularly delivering a mixture including a biopolymer (e.g., chitosan) and a chemical crosslinking agent (e.g., genipin) to an aneurysm. The method further includes mixing the biopolymer and the chemical crosslinking agent to initiate chemical crosslinking of the biopolymer. The mixture is delivered to the aneurysm via a lumen and an exit port of a catheter while the chemical crosslinking is ongoing. The mixture exits the catheter as a single cohesive strand that at least partially agglomerates to form a mass occupying at least 75% of a total internal volume of the aneurysm. During delivery of the mixture, the method includes expanding a tubular flow diverter to reinforce a neck of the aneurysm.
A61B 17/12 - Surgical instruments, devices or methods, e.g. tourniquets for ligaturing or otherwise compressing tubular parts of the body, e.g. blood vessels or umbilical cord
A61L 31/14 - Materials characterised by their function or physical properties
A61L 31/18 - Materials at least partially X-ray or laser opaque
Devices, systems, and methods for treating aneurysms are disclosed herein. According to some embodiments, the present technology includes a treatment system comprising a delivery shaft, a manipulation shaft slidably positioned within the lumen of the delivery shaft, and an occlusive device configured for implantation within the aneurysm. The occlusive device can comprise a plurality of filaments that are secured to one another at a proximal end of the occlusive device by a cured material. The occlusive device can comprise inner and outer layers of braided filaments, wherein the proximal end region of the inner layer has an exposed portion that extends proximally beyond the proximal end region of the outer layer, and wherein the cured material extends into and fills interstices between the braided filaments at the proximal end regions of the inner and outer layers.
