Abstract
A method of providing a colonic lavage includes the steps of delivering a predetermined volume of lavage liquid to the colon to fill the colon with lavage liquid to a predetermined level, substantially maintaining the predetermined level of lavage liquid within the colon for a predetermined time in a hold cycle to hydrate impacted material within the colon, inducing a pulsed motion of the lavage liquid within the colon during the hold cycle to enhance hydration and break up of impacted material within the colon and to induce peristaltic activity of the colon, and draining lavage liquid from the colon. The step of inducing pulsed motion of the lavage liquid within the colon may be accomplished through an inverse pulsed technique or a pulsed hold technique.
