  • Patent number: 12350155
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, the catheter can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to a leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

  • Publication number: 20240231428
    Abstract: Disclosed embodiments describe techniques for personal area network (PAN) enablement. PAIN connection uses an interconnection laminate substrate for connectivity of personal area network components. The interconnection laminate substrate may be flexible or rigid. In one preferred form of the invention, the interconnection laminate substrate is flexible. A plurality of personal area network components is provided. An interconnection laminate substrate is provided within a manufactured article (e.g., a soft good assembly), where the interconnection laminate substrate enables connectivity among the plurality of personal area network components, and where the interconnection laminate substrate comprises interconnection wiring encapsulated in at least one protective encapsulation layer, with the interconnection wiring being coupled to a plurality of exposed connectors.

  • Patent number: 12010229
    Abstract: Systems and methods for enforcing durability of second level encryption keys by a key management system (KMS) are provided. In embodiment, a method includes: receiving a first request to encrypt a first level key, the request including the first level key and a second level key identification associated with a stored encrypted second level key; determining that a durability check of the encrypted second level key is required based on the request; determining a durability status of the encrypted second level key by comparing actual storage of the encrypted second level key in one or more storage locations with predetermined storage rules for a durability level of the encrypted second level key, wherein the durability status indicates that the storage of the encrypted second level key complies with the durability level; and sending a notification regarding the durability status to the data storage service.

  • Patent number: 11933528
    Abstract: Methods and systems provided for determining a phase state and/or for determining a degree of subcooling in a fluid. An exemplary method for operating a refrigeration cycle includes flowing a refrigerant through a metering device and calculating a pressure differential of the refrigerant across the metering device. Further, the method includes determining whether the refrigerant is a saturated liquid based on the pressure differential. The method includes, when the refrigerant is not a saturated liquid, cooling the refrigerant upstream of the metering device.

  • Publication number: 20230404756
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

  • Patent number: 11807074
    Abstract: A thermal management system for a vehicle includes a plurality of fluid flow circuits including a heating ventilation and air conditioning (HVAC) circuit circulating a flow of refrigerant therethrough and including an evaporator, a chiller heat exchanger, a first expansion valve located upstream of the evaporator, a second expansion valve located upstream of the chiller heat exchanger, and a heat exchanger located fluidly upstream of the expansion valves. A propulsion cooling circuit circulates a flow of coolant therethrough which is utilized to condition one or more propulsion components of the vehicle. The flow of coolant is directed through the heat exchanger, thus subcooling the flow of refrigerant. A controller is operably connected to one or more control points of the thermal management system and is configured to adjust the one or more control points to achieve a target amount of subcooling of the flow of refrigerant at the heat exchanger.

  • Patent number: 11685234
    Abstract: A control system includes a refrigerant recovery module and at least one of a valve control module and a compressor control module. The refrigerant recovery module is configured to generate a refrigerant recovery signal to initiate a recovery of refrigerant from a first heat exchanger of a thermal system for an electric vehicle, and to stop the refrigerant recovery based on a temperature of refrigerant circulating through the first heat exchanger. The valve control module is configured to open a first valve to allow refrigerant to flow through the first heat exchanger in response to the refrigerant recovery signal. The compressor control module is configured to increase a speed of a compressor disposed upstream from the first heat exchanger in response to the refrigerant recovery signal.

  • Patent number: 11666441
    Abstract: Methods and devices for transvascular prosthetic chordae tendineae implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet anchor having a leaflet suture is secured to the mitral valve leaflet. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae. The suture lock has a body with a suture path extending therethrough. A wall in the housing is movable to reduce the cross section of the suture path. A drive mechanism advances the movable wall to clamp sutures extending through the suture path, in response to rotation of a coupling on the housing.
