Abstract
This invention disclosed herein provides methods, devices, software products, and systems for infusing a fluid into a blood vessel is provided that includes the step of administering the fluid into the blood vessel in programmed pulses. The programmed pulses generally defined by programmed pulse variables that include a fluid flow rate, a frequency, and a duration. Values of the programmed pulse variables may be determined based at least in part on a fluid property of the fluid to be infused that is relevant to streaming, blood flow in the blood vessel to be infused, a catheter size, or a patient profile.

11. A programmed pulse infusion device comprising:
-
a pump;
a controller with associated memory interfacing with the pump;
a fluid reservoir containing a fluid feeding the pump, the controller providing a drive signal for the pump to deliver the fluid for infusion into a blood vessel in programmed pulses defined by programmed pulse variables comprising a fluid flow rate, a frequency, and a duration; and
a balloon drive for operating an occlusion catheter for reducing blood flow in the blood vessel. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
