Devices, systems, and methods for simultaneous liquid infusion and catheter motion

An actuation device for a vascular treatment system, the actuation device comprising:

• a movement actuator configured to be operatively coupled to a vascular treatment device, the movement actuator being actuatable to move at least a portion of the vascular treatment device in a proximal direction within a treatment space of a subject;
• a liquid reservoir carrying a liquid;
• a liquid infusion actuator operatively coupled to the liquid reservoir, the liquid infusion actuator being actuatable to deliver the liquid from the liquid reservoir to the treatment space in a distal direction via the vascular treatment device;
• and
• a user input being actuatable to simultaneously actuate the movement actuator and the liquid infusion actuator.

A vascular treatment system, comprising:

• a vascular treatment device configured to be disposed within a treatment space of a subject;
• an actuation device operatively coupled to the vascular treatment device, the actuation device comprising:
• a movement actuator operatively coupled to the vascular treatment device, the movement actuator being actuatable to move the vascular treatment device in a proximal direction within the treatment space;
• a liquid infusion actuator configured to operatively couple to a liquid reservoir, the liquid infusion actuator being actuatable to deliver a liquid from the liquid reservoir to the treatment space in a distal direction via the vascular treatment device;
• and
• a user input being actuatable to simultaneously actuate the movement actuator and the liquid infusion actuator.
