Abstract

The present invention relates to a fluid flow device. The device includes an elongate body having a proximal end, a distal end, and a length therebetween, at least one source fluid inflow port, at least one waste fluid outflow port, at least one well inlet port positioned at the distal end of the elongate body, at least one well outlet port positioned at the distal end of the elongate body, at least one conduit connecting the at least one source fluid inflow port to the at least one well inlet port, and at least one conduit connecting the at least one waste fluid outflow port to the at least one well outlet port.

Claims (7)

1. A method of applying fluid flow to biological cells in a culturing well, comprising:

positioning a fluid flow device in a culturing well of a multiwell cell culture plate, the device comprising an elongate tubular body having an upper proximal end, a lower distal end, and a length therebetween, the distal end of the elongate tubular body configured for insertion into a well of a multiwell cell culture plate; at least one first source port positioned on the distal end; at least one first waste port positioned on the distal end; at least one second source port positioned on the elongate tubular body above the at least one first source port; at least one second waste port positioned on the elongate tubular body above the at least one first waste port; at least one source conduit positioned within the body connecting a single first source port out of the at least one first source port(s) to a single second source port out of the at least one second source port(s); and at least one waste conduit positioned within the body connecting a single first waste port out of the at least one first waste port(s) to a single second waste port out of the at least one second waste port(s), such that the at least one first source port and the at least one first waste port are positioned within the well; and

flowing a fluid through the device;

wherein the fluid applies a shear stress to the cells in the culturing well.

2. The method of claim 1 , wherein flowing fluid through the device further comprises activating a pump in line with the at least one second source port.

3. The method of claim 2 , wherein the flow rate of the fluid is adjustable.

4. The method of claim 1 , wherein shear stress is about 4 dynes/cm 2 .
