Systems and methods for embolizing blood vessels

A system comprising:

• an assembly that is at least partially insertable into a patient, the assembly comprising:
• a catheter that is insertable into an artery, wherein the catheter has an outlet, wherein the catheter is configured to receive therethrough an embolic agent and deliver the embolic agent through the outlet;
• an occlusion device coupled to the catheter, wherein the occlusion device is configured to fully occlude the artery;
• a pressure sensor that is configured to determine a pressure within the artery at a location proximal of the occlusion device;
• a display;
• and
• a computing device in communication with the display and the pressure sensor, the computing device comprising a memory and at least one processor in communication with the memory, wherein the memory comprises instructions that, when executed by the at least one processor, cause the at least one processor to:
• receive a first pressure reading from the pressure sensor with the occlusion device in a non-occluding configuration, wherein the first pressure reading is indicative of a baseline pressure without the artery being occluded;
• receive a second pressure reading from the pressure sensor with the occlusion device in an occluding configuration, wherein the second pressure reading is indicative of the artery being fully occluded;
• receive at least one additional pressure reading from the pressure sensor;
• compare the at least one additional pressure reading to the second pressure;
• and
• display, on the display, a progress indicator indicating a proximity of the at least one addition pressure reading to the second pressure relative to the first pressure.

A method comprising:

• receiving, from a pressure sensor within an artery, a first pressure reading indicative of a baseline pressure without the artery being occluded;
• occluding, with an occlusion device, the artery;
• receiving, from the pressure sensor within the artery proximal of the occlusion device, a second pressure reading indicative of the artery being fully occluded;
• and
• determining a threshold stop pressure based on a difference between the first pressure reading and the second pressure reading.
