Abstract: A system includes a screw tower, an instrument, and a housing. The instrument includes a driver shaft extendable longitudinally through the screw tower, and a threaded sleeve mounted on a proximal portion of the driver shaft. The housing includes one or more retention members coupleable to the screw tower, and a threaded button threadably coupleable to the threaded sleeve. The threaded sleeve is rotatable about a longitudinal axis to urge the driver shaft longitudinally relative to the screw tower.

Abstract: Active end-effectors for guiding an instrument during a robot-assisted surgery. The surgical robot system may include a robot having a robot base, a robot arm coupled to the robot base, and the active end-effector coupled to the robot arm. The active end-effector may have a slide mechanism, which may provide for a greater range of motion of a surgical instrument along a vertical axis.

Abstract: Expandable electrophysiology catheters having electrodes mounted on splines of an expandable member are described. The splines of the expandable member include subsegments between a proximal location and a distal intersection at a central axis. The subsegments can include respective top-down profiles, and at least one of the top-down subsegment profiles is straight between the central axis and an adjacent top-down subsegment profile. The subsegments can be interconnected to extend continuously about the central axis from the proximal location to the distal intersection. Other embodiments are also described.

Abstract: Expandable electrophysiology catheters having electrodes mounted on splines of an expandable member are described. The splines of the expandable member include subsegments between a proximal location and a distal intersection at a central axis. The subsegments can include respective top-down profiles, and at least one of the top-down subsegment profiles is straight between the central axis and an adjacent top-down subsegment profile. The subsegments can be interconnected to extend continuously about the central axis from the proximal location to the distal intersection. Other embodiments are also described.

Abstract: Processing user-triggered, broker-assisted workflows. A content management system is configured to host a hierarchy of content objects that are partitioned into two or more user contexts. A first workflow object is configured and then stored into a first one of the two or more user contexts. A computer-implemented service agent is configured to receive a workflow trigger from an event raised in a second one of the two or more user contexts. The computer-implemented service agent executes in the second one of the two or more user contexts while processing the first workflow object using permissions that are associated with the first one of the two or more user contexts. The computer-implemented service agent processes the workflow object in the context of the first one of the two or more user contexts. Results from execution of the workflow objects are provided to the process that raised the workflow trigger.
