Abstract: A medical assembly includes a guide catheter with a lumen extending therethrough and an electrocautery member slidingly disposed within the lumen. The electrocautery member has an elongate shaft with a proximal shaft segment and a distal shaft segment adapted to be movable between a puncture position and a laceration position. In some cases, a hinge segment is disposed between the proximal shaft segment and the distal shaft segment and includes a leading edge adapted to form a puncture within a cardiac valve leaflet when the distal shaft segment is in its puncture position and a trailing edge adapted to lacerate the cardiac valve leaflet when the distal shaft segment is in its laceration position. In some cases, the electrocautery member includes electrically isolated puncture and lacerating electrodes.

An engine comprising an engine surface in an airflow path, a sensor positioned on the engine surface, and a smart-material-based feature positioned on the engine surface, the smart-material-based feature triggered to modify the airflow path when the sensor outputs an indication of a detected deviation from a reference value of an operating parameter of the engine.

Abstract: A medical system for performing a procedure within a heart of a patient includes an elongate member having a proximal portion and a pre-formed distal portion. The pre-formed distal portion is configured to contact a portion of a fossa ovalis of the heart. The elongate member includes a lumen extending from the proximal portion to a location proximal of the pre-formed distal portion. The system includes a perforating device having a proximal portion and a distal portion including a puncturing tip. The perforating device is configured to translate within the lumen. The puncturing tip is located substantially in the center of the pre-formed distal portion when the pre-formed distal portion is in contact with the fossa ovalis.

The controller is configured to track catheter assembly positions within the organ based on a plurality of electrical signals from the tracking sensor, determine a first catheter assembly position based on a first electrical and determine a second catheter assembly position based on a second electrical signal, constrain the second position with the first position, and generate an anatomical map of an organ of the electrophysiological procedure with a visualization of the catheter assembly having the second position constrained with the first position.

Abstract: Mapping of database partitions to available nodes. Metric information related to the partitions of the database are stored. One or more metrics associated with the partitions are gathered. A plurality of potential mappings of partitions to nodes are evaluated. One of the potential mappings of partitions to nodes to result in improved metric distribution among the nodes and the partition moves are within a pre-selected move constraint is selected. The selected potential mapping is implemented by moving one or more partitions between one or more nodes.

Abstract: The described technology is generally directed towards processing various customer input data to extract frequently recurring customer experience themes, including positive and negative sentiment regarding customer experiences. Natural language processing, image processing, speech recognition and/or computer vision techniques can be used on customer-related data to determine themes, tests and scenarios, as well as discover insights that can be used to improve customer experiences. The technology can be used to recreate a customer engagement, journey and overall experience by designing test scenarios around failure themes.

Abstract: A system, apparatus, and method of using the same are disclosed for carrying out a transvascular procedure such as a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure using energy to create a tract between the hepatic vein and the portal vein. The present invention provides a method using a flexible radiofrequency (RF) catheter having a lumen therethrough. The method involves the steps of advancing the flexible RF catheter into a first vessel; advancing a guiding sheath overtop of the flexible RF catheter; steering the guiding sheath to direct a distal tip of the RF catheter towards a second vessel; and, delivering RF energy via the flexible RF catheter, forming a tract from the first vessel and entering the second vessel.
