  • Patent number: 12544130
    Abstract: A catheter system for ablation of tissue around a blood vessel, e.g., the pulmonary artery, to reduce neural activity of nerves surrounding the blood vessel. The catheter system includes an elongate shaft having a proximal portion coupled to a handle, and a distal portion. The distal portion includes a transducer and an expandable anchor, which may be actuated to transition between a collapsed delivery state and an expanded deployed state where the anchor centralizes the transducer within the blood vessel. The transducer may be actuated to emit energy to reduce neural activity of the nerves surrounding the blood vessel. Systems and method are further provided for confirming that neural activity of the nerves surround the blood vessel has been sufficiently reduced.

  • Publication number: 20250352264
    Abstract: A catheter system for ablation of tissue around a blood vessel, e.g., the pulmonary artery or the subclavian artery, to reduce neural activity of nerves surrounding the blood vessel, e.g., nerves surrounding the pulmonary artery or nerves of the stellate ganglion adjacent to the subclavian artery. The catheter system includes an elongate shaft having a proximal portion coupled to a handle, and a distal portion. The distal portion includes a transducer and an expandable anchor, which may be actuated to transition between a collapsed delivery state and an expanded deployed state where the anchor centralizes the transducer within the blood vessel. The transducer may be actuated to emit energy to reduce neural activity of the nerves surrounding the blood vessel.

  • Patent number: 9723433
    Abstract: A medical monitoring and communication system for wireless communication between an implantable medical device, a mobile user device, and a remote server includes a sensor device coupled to the implantable medical device. The sensor device is configured to default to a master mode prior to pairing with the mobile user device, listen for a request to connect from the mobile user device, refrain from communicating with the mobile user device responsive to the request to connect from the mobile user device being invalid, and switch to a slave mode to allow cooperative pairing with the mobile user device responsive to the request to connect from the mobile user device being valid. The mobile user device facilitates communication between the sensor device and the remote server when the mobile user device and the sensor device are cooperatively paired.
