The resilient bulb portion is adapted and configured to transition, through engagement with an insertion device (120), between a first condition in which the bulb portion has a first diameter and a first length and a second condition in which the bulb portion has a second diameter and a second length for insertion and removal through a patient's abdominal wall, and to be retained in place therethrough. The second diameter is less than the first diameter, and the second length is greater than the first length.
