Abstract

A mechanotransductive bowel extender device that can be used to correct short bowel syndrome by applying tension to the bowel tissue which, via the process of mechanotransduction, grows in length in response to the applied tension. Such a device is placed within the small bowel and applies tension over a period of several days or weeks by attaching to the lumen of the bowel at two different locations and moving those two points apart, stretching the tissue between. The extender device further capable of localized application and/or evacuation of medically relevant liquid and other material within the bowel.
