Cryo-fixation lead extraction device with cryogen supply line
A cryo-fixation lead extraction device has been granted a patent, US11896281B2, for its innovative design and functionality. The device comprises a lead extraction catheter with a liner that selectively accepts a lead being extracted longitudinally. The liner includes at least one cryogen supply line to generate a frozen zone adjacent the distal catheter end, facilitating lead extraction. A cutting feature is also included to mechanically cut into the frozen tissue zone. The device is designed for rotational movement, and a distal freezing chamber ensures a closed cryogen loop to prevent fluid passage distally.
Furthermore, the patent also covers a cryo-fixation lead extraction system that includes a cryogen fluid source, regulator, operator interface, and computing device for controlling and monitoring the device during operation. The system features a portable mounting frame for easy transport and operation. The method of lead extraction using cryogenics involves directing cryogen fluid to create a frozen zone, cutting into the tissue to loosen the lead, and moving the lead proximally. The method also includes using a stylet for assistance and ensuring a closed cryogen loop for efficient operation. The temperature of the frozen tissue zone is maintained between -5°C to -30°C for optimal results.
