Abstract: A prosthetic heart valve includes a non-collapsible annular frame extending in a longitudinal direction between an inflow edge and an outflow edge, and a valve assembly connected to the frame. The frame includes a plurality of annularly spaced commissure posts adjacent the outflow edge, each of the commissure posts including a tip and a post slot spaced apart from the tip. The prosthetic heart valve further includes a radiopaque element including an elongated main body having a first end and a second end. The radiopaque element may extend around the tip and through the post slot of at least one of the commissure posts so that a portion of the main body extends between the slot and the tip. Alternatively or additionally, a radiopaque element may be positioned adjacent a base of the frame.

Abstract: Method and system that includes receiving an sensed data point from an industrial process; applying a mapping model to map the sensed data point to a respective embedding that has reduced dimensionality relative to the sensed data point; determining, based on a comparison of the respective embedding to prior embeddings, if the mapping model needs to be updated or not. When the mapping model needs to be updated, applying manifold learning to learn an updated set of model parameters for the mapping model. When the mapping model does not need to be updated, applying a classification model to the respective embedding to predict a classification for the sensed data point.

Abstract: A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft. The compartment may be sized to receive the prosthetic heart valve. The inner shaft and the distal sheath may be movable relative to one another. A spine may extend along the outer shaft, the spine biasing the outer shaft so that the outer shaft tends to bend in a pre-determined direction.

Abstract: MPC controller systems and methods are disclosed that may be applied to various different types of MPC controllers and methods for use in any desired or appropriate controller settings, such as physical systems with non-linearities that require careful modelling tactics, which are considered complex systems. Complex systems include fast systems which are those where solving the descriptive model of the system has the potential to surpass the closed loop sampling time required to control the system. Examples of complex fast systems are robot manipulators, quadracopters and injection speed of an injection molding process.

Abstract: A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft, the compartment being sized to receive the prosthetic heart valve in a collapsed condition. The inner shaft and the distal sheath may be movable relative to one another. The delivery device may also include a tube member and an outer sleeve overlying the tube member. The tube member may be configured to rotate or twist upon axial movement of the outer sleeve with respect to the tube member, the rotation or twisting of the tube member configured to rotate the prosthetic heart valve when the prosthetic heart valve is received within the compartment in the collapsed condition.

Abstract: A multi-sensor threat detection system and method for elevated temperature detection using commodity-based thermal cameras and mask wearing compliance using optical cameras. The proposed method does not rely on the accuracy of thermal cameras, but the combination of mathematics, statistics, machine learning, artificial intelligence, computer vision and Manifold learning to construct a classifier, or set of classifiers, that are able to, either alone or working as an ensemble, evaluate a person as being ‘normal temperature’ or ‘elevated temperature’ by virtue of ‘how they present to the camera’ vs. any absolute temperature measurements from the camera itself.

Abstract: An assembly for collapsing a prosthetic heart valve includes a compression member having a plurality of arms pivotable between a first orientation in which side edges of adjacent arms are spaced apart from one another and a second orientation in which the adjacent arms contact one another. A translating member is movable along the arms to pivot the arms from the first orientation to the second orientation to collapse the prosthetic heart valve. A separation tool includes ribs defining channels sized to receive the struts of a stent of a prosthetic heart valve to keep the struts separated from one another as the prosthetic heart valve is collapsed.

Abstract: A delivery system has a delivery capsule with a detachable portion including first and second open ends with a tapered wall extending therebetween to compress and guide a collapsible heart valve into the delivery capsule. The detachable portion may be detached from the delivery capsule after loading the collapsible heart valve to leave a smooth distal surface on the delivery capsule. Detachment of the detachable portion may occur by breaking or removing a frangible member interposed between the detachable portion and the delivery capsule.

Abstract: At least a portion of fabrics for use in medical devices is formed from polymeric materials. The fabrics may be uncoated, partially coated or fully coated with one or more layers of a polymer. The fabrics may be used for the leaflets and/or cuffs of prosthetic heart valves and as a component of other medical devices.

Abstract: An emulator is described herein, wherein the emulator is configured to emulate a rotary energy generator. The rotary energy generator can be one of a wind turbine, a diesel engine, or a hydrokinetic generator. The emulator includes an electromechanical motor that is mechanically linked to a generator. A motor drive is electrically coupled to the electromechanical motor, and controls torque at a rotor of the electromechanical motor. Electromagnetic torque produced by the generator is estimated, and the motor drive is controlled based upon the estimated generator torque.
