Abstract
An anorectal expulsion device includes a balloon having a wall that extends between proximal and distal ends of the balloon and defines a balloon interior. The balloon interior contains a self-expanding, low compression-set material (e.g., open cell foam). The device also includes a catheter that extends through the proximal end of the balloon and at least a portion of the balloon interior. An interior of the catheter is in fluid communication with the balloon interior. The device also includes a termination component (e.g., a cap or a valve) coupled to the catheter at a position along the catheter that is outside of and proximal to the proximal end of the balloon (e.g., at the proximal end of the catheter). The physical configuration of the termination component is adjustable, and controls whether the balloon interior is in fluid communication with the external environment.
