Abstract: A non-transitory computer readable medium containing instructions that when executed by at least one processor, cause the at least one processor to perform operations for monitoring partitioning of a medical instrument during an endovascular procedure. The operations may further be configured to obtain an input to activate a partitioning mechanism associated with a medical instrument within a lumen of a catheter, the catheter being positioned within a body. Further, embodiments may be configured in response to the input, to activate the partitioning mechanism. The operations may further be configured, following the activation, to obtain partitioning outcome data. The operations may determine, based on the partitioning outcome data, whether the medical instrument may be in a severed state or a connected state. The operations may, if the severed state of the medical instrument is detected, output a success notification.
