Abstract: A probe may be inserted into a body cavity to perform diagnostic intervention(s), therapeutic intervention(s), or both. The probe may be inserted through a body aperture that is naturally occurring or man-made, intentionally or by accident. The body aperture may form a seal encircling the probe so that insufflation retention material may be effectively retained in the body cavity so that an operator can perform the intervention(s). However, there may be leakage of the insufflation material. The insufflation retention device is configured to form an effective seal contactingly adjacent the body aperture and to provide a passageway for the introduction of the probe into the body cavity, such that a diagnostic intervention or therapeutic intervention or both may be performed.
