1. A system comprising:
a neurovascular bundle (NVB) comprising an artery, a vein, and a nerve, wherein (a)(i) the artery directly contacts at least one of the vein and the nerve, (a)(ii) the vein directly contacts at least one of the artery and the nerve, and (a)(iii) the nerve directly contacts at least one of the vein and the artery;
a first length of tubing directly contacting at least one of the vein, the artery, and the nerve;
a second length of tubing to couple to the first length of tubing; and
a peristaltic pump comprising a number of rollers and the number of rollers is no more than three rollers;
wherein in an operative orientation (b)(i) the second length of tubing directly contacts at least one of the number of rollers, (b)(ii) a first end of the first length of tubing is closed and a second end of the first length of tubing is open, (b)(iii) a first end of the second length of tubing is closed and a second end of the second length of tubing is open, (b)(iv) the second end of the first length of tubing is communicatively coupled to the second end of the second length of tubing, (b)(v) the peristaltic pump reciprocally moves fluid back and forth within the first and second lengths of tubing in response to the number of rollers intermittently contacting the second length of tubing.
