A recently granted patent (Publication Number: US11918765B2) discloses an assembly designed for accessing a patient's superior vena cava without the need for visualizing the patient's vasculature. The assembly includes a stylet with a unique core wire configuration that transitions between pre-formed shapes to facilitate insertion. The core wire features specific bends and segments, including a narrow segment with a reduced width to enhance deflection of the distal tip towards the target area. Additionally, the core wire is designed to automatically align the distal tip towards the superior vena cava during insertion, improving accuracy and efficiency.

Furthermore, the assembly incorporates a conductive coil for passive sensor coil capabilities, aiding in navigation during the procedure. The core wire, made of a nickel titanium alloy, is conductive of an electrocardiogram (ECG) signal, enhancing its functionality. The assembly's innovative design, including specific angles and lengths of pre-formed bends, aims to optimize the access to the superior vena cava while ensuring minimal torqueability of the core wire. Overall, this patented assembly represents a significant advancement in medical devices for accessing critical vascular structures with precision and effectiveness.
