A recently granted patent (Publication Number: US11925778B2) discloses a method for treating a patient involving a unique catheter insertion device. The method includes inserting a catheter with a needle and guidewire into a patient's blood vessel, rotating a thumbwheel to advance the guidewire without moving the catheter, extending the catheter further into the vessel over the guidewire, and finally removing the needle and guidewire from the catheter. The device also features a blood flashback chamber for observing blood in the chamber before advancing the guidewire, ensuring proper placement.

Furthermore, the patent claims detail additional features of the catheter insertion device, such as the orientation of the thumbwheel, engagement with a friction wheel for guidewire advancement, and the design of the guidewire with a coiled configuration. The method also involves an actuator mechanism for retracting the needle and guidewire simultaneously, enhancing the efficiency of the procedure. The patent highlights various configurations of the guidewire coils and their transition during the insertion process, emphasizing the precision and effectiveness of the device in treating patients. Overall, the patented method and device offer a novel approach to catheter insertion, potentially improving patient outcomes and procedural efficiency in medical settings.
