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.
Claims28
A method of infusing a fluid into a blood vessel comprising:
- reducing blood flow in the blood vessel;
- and
- administering the fluid into the blood vessel in programmed pulses defined by programmed pulse variables comprising a fluid flow rate, a frequency, and a duration.
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.
A computer readable medium comprising program code that when executed enables a user to determine values of programmed pulse variables for infusing a fluid in a blood vessel in programmed pulses defined by the programmed pulse variables comprising a fluid flow rate, a frequency, and a duration, while blood flow is reduced in the blood vessel.
