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.

An integrated vascular delivery system having a frame configured to receive a catheter insertable in a patient to deliver fluid at an insertion site. The frame includes a first hub, a second hub, and a pair of flexible lateral members extending between the hubs and including a tubular lateral member. The system also includes a fluidic channel that fluidically communicates with the catheter, wherein the fluidic channel passes through the tubular lateral member and at least one of the hubs, and includes a fixed turnabout portion in which fluid flows in a direction different from that within the catheter. The first and second hubs provide anchoring points on the patient distributed around the insertion site and on opposite ends of the catheter, thereby anchoring the frame to the patient and stabilizing the catheter. A method is provided for using an integrated vascular delivery system.
