GUIDEWIRE ADVANCEMENT AND BLOOD FLASHBACK SYSTEMS FOR A MEDICAL DEVICE INSERTION SYSTEM

摘要

Embodiments of the present invention are directed to guidewire advancement and blood flashback systems. In particular, the insertion tool includes a frangible guidewire lever configured to break and prevent further movement of the guidewire if the guidewire becomes caught. Such a feature can prevent breakage of a distal portion of the guidewire which otherwise could undesirably lead to an embolism. The insertion tool can further include a blood flash indicator that has a simplified coupling with the needle. The insertion tool can further include a guidewire advancement assembly configured to allow the clinician to hold the insertion tool proximate a distal end and operate the guidewire advancement with one hand while providing increased control over the insertion tool. The insertion tool can further include a safety clip coupled with the catheter hub and configured to close about the needle tip when the catheter is detached from the device.
