A recently granted patent (Publication Number: US11925772B2) discloses a catheter system comprising a catheter hub with a hub body designed to connect to a catheter. The hub passage extends longitudinally between the proximal and distal ends of the hub body, connecting to a catheter passage to create a continuous passage. The catheter connector assembly, located adjacent to the hub passage, includes hub electrical contacts in electrical communication with the catheter via a magnetic attachment mechanism. The assembly is recessed with respect to the catheter hub, providing a unique design for catheter connection.

Furthermore, the catheter system includes various configurations such as lateral and distal orientation of the catheter connector assembly, a hollow portion in the catheter hub with wires connecting the electrical contacts, and a magnetic attachment mechanism with horizontally and vertically facing magnets. The system also features a vertical ridge near the magnetic attachment mechanism and a catheter with a tubular structure and a braided structural layer for communication with electrically powered components. The distal end of the catheter hub comprises a tip with multiple electrical contacts for connection to the catheter. Overall, the patent highlights innovative features aimed at improving catheter systems for medical applications.
