An embodiment includes a system comprising: an artery, a vein, and a nerve; a first length of tubing adjacent at least one of the vein, artery, and nerve; a second length of tubing to couple to the first length of tubing; and a pump comprising a number of actuators; wherein when the system when operating is configured such that (b)(i) the second length of tubing couples to at least one of the number of actuators, (b)(ii) ends of the first and second lengths of tubing are closed, (b)(iii) a second end of the first length of tubing is operatively coupled to a second end of the second length of tubing, (b)(v) the pump pulsates fluid within the first length of tubing in response to the number of actuators intermittently contacting the second length of tubing.

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.

2. A system comprising: an artery, a vein, and a nerve; a first length of tubing adjacent at least one of the vein, the artery, and the nerve; a second length of tubing configured to couple to the first length of tubing; and a pump comprising a number of actuators; wherein when the system is in an operative orientation the system is configured such that (b)(i) the second length of tubing couples to at least one of the number of actuators, (b)(ii) a first end of the first length of tubing is closed, (b)(iii) a first end of the second length of tubing is closed, (b)(iv) a second end of the first length of tubing is operatively coupled to a second end of the second length of tubing, (b)(v) the pump pulsates fluid within the first length of tubing in response to the number of actuators intermittently contacting the second length of tubing.

3. A method comprising: coupling a second length of tubing to a first length of tubing, wherein (a)(i) the first length of tubing is adjacent a neurovascular bundle (NVB), (a)(ii) a first end of the first length of tubing is closed and a first end of the second length of tubing is closed, and (a)(iii) the first length of tubing has a first flexibility, the second length of tubing has a second flexibility, and the first flexibility is more flexible than the second flexibility; coupling the second length of tubing to a peristaltic pump, the peristaltic pump comprising a number of rollers that are less than four rollers; operating the peristaltic pump to radially pulsate the first length of tubing in response to the number of rollers intermittently contacting the second length of tubing.
