Abstract
A system may include a pump. A system may include a catheter including a plurality of spaced apart orifices. A system may include a controller operatively coupled to the catheter, the controller being configured to control fluid flow to the catheter.
Claims20
A system comprising:
- a pump;
- a catheter including a plurality of spaced apart orifices;
- and
- a controller operatively coupled to the catheter, the controller being configured to control fluid flow to the catheter.
1 more element
A computer implemented method of delivering a homogenous fluid, comprising:
- determining a plurality of orifice sizes to maintain homogenous flow rates through a catheter;
- and
- controlling a valve of the catheter so that fluid flows through orifices corresponding to the plurality of orifice sizes that will maintain the homogenous flow rates through the catheter.
A non-transitory computer readable medium having instructions stored thereon, wherein execution of the instructions by a processor causes the processor to:
- receive accelerometer information;
- determine a supine position or an upright position based on the accelerometer information;
- control operation of a pump based on the determination of the supine position or the upright position;
- and
- provide flow from the pump to a catheter defining a first aperture, a second aperture, and a third aperture,
- wherein the first aperture, the second aperture, and the third aperture are spaced equidistantly along a longitudinal axis,
- wherein the first aperture defines a first diameter, the second aperture defines a second diameter, and the third aperture defines a third diameter,
- wherein the third diameter is greater than the second diameter, and
- wherein the second diameter is greater than the first diameter.
