Abstract: A catheter system for pressure wave and inertial impulse generation for intravascular lesion disruption includes a balloon coupled to an elongate shaft, and a first and second light guide disposed along the elongate shaft. The first and second light guides each include a diverting feature in optical communication with at least one light window to direct light to exit each light guide toward a side surface portion thereof and toward the balloon. A method includes expanding the balloon from a collapsed configuration to a first expanded configuration, and activating a light source in optical communication with each light guide to provide sub-millisecond pulses of light to the diverting features, thereby inducing plasma formation in a balloon fluid, causing rapid bubble formation, and imparting pressure waves upon the treatment site.

Abstract: A transmission includes a first housing part, a second housing part connected to the first housing part, and bearings accommodated in the first housing part and supporting an input shaft in a rotatable manner. The input shaft projects through a recess that extends through the second housing part, and a cover part is connected to the first housing part. The cover part or a flange part inserted into the cover part accommodates a sealing system, which provides sealing with respect to the input shaft. The second housing part has an inlet for lubricating oil, which terminates in an axial bore being open with respect to the side of the first housing part facing the cover part, and in a second annular space. The opening of the axial bore facing the cover part is covered and/or sealed by the cover part, and rolling elements of two bearings at least also restricting and/or surrounding the second annular space together with the first housing part.

Abstract: Robots and/or a robot coordinator are provided to execute an overall task by partitioning the task into subtasks and by coalescing results and/or output of the subtasks. The robot coordinator may coordinate, control, and/or program a set of robots to operate within different sections of a site and to execute subtasks associated with different tasks that fall within their respective sections in parallel. The robot coordinator may coordinate, control, and/or program the same or different set of robots to coalesce results and/or output for subtasks for a particular task from the different sections to complete the overall task. For instance, a first set of robots may retrieve objects that are stored at storage locations within the sections in which each robot operates, and a second set of robots may rotate moveable storage apparatus across the sections so that each storage apparatus stores all objects of a particular order.

The system also includes a display device and a coordinating device that detects retrieval of an object, determines that the object belongs to a particular customer order, selects, based on the second mapping, a particular container that is used to store objects of the particular customer order, and directs the transfer of the object to the particular container by modifying the display device to present a particular visual identifier of the particular container.

Abstract: Transaction handling computing elements comprise a network core that processes transaction requests into a blockchain, wherein a data block is a collection of transactions, and wherein an Unspent Transaction Output (UTXO) supporting the blockchain is an output from a finalized transaction. The elements interoperate with a transaction signing mechanism that associates a set of addresses on the blockchain with a delegate address, the delegate address having a set of signing public keys corresponding to one or more signing private keys used to sign UTXOs. In association with a new transaction being processed by the set of transaction handling components, a signing public key for an associated UXTO is located by following an address chain that includes an address in the set of addresses together with the delegate address. The signing public key is retrieved from a location associated with the delegate address and then used to sign (unlock) the associated UXTO.

Abstract: A robot may include a spatiotemporal controller for controlling the kinematics or movements of the robot via continuous and/or granular adjustments to the actuators that perform the physical operations of the robot. The spatiotemporal controller may continuously and/or granularly adjust the actuators to align completion or execution of different objectives or waypoints from a spatiotemporal plan within time intervals allotted for each objective by the spatiotemporal plan. The spatiotemporal controller may also continuously and/or granularly adjust the actuators to workaround unexpected conflicts that may arise during the execution of an objective and delays that result from a workaround while still completing the objective within the allotted time interval. By completing objectives within the allotted time intervals, the spatiotemporal controller may ensure that conflicts do not arise as the robots simultaneously operate in the site using some of the same shared resource.

Abstract: An atherectomy system includes an advancer assembly and a drive assembly that is adapted to translate relative to the advancer assembly. A control knob extends from the drive assembly such that translating the control knob results in the drive assembly translating relative to the advancer assembly.

A feedback modifier is operably coupled between the drive assembly and the advancer assembly and is adapted to provide a user of the atherectomy system with similar feedback via the control knob regardless of whether the user is moving the drive assembly in an anterograde ablation direction or a retrograde ablation direction.
