ABSTRACT:
An insertion device (82) to aid introduction of an overtube (90) into a colon over a previously inserted colonoscope (2). The insertion device (82) comprises an elongate tubular sheath (80), which defines a lumen to receive the colonoscope (2) and the overtube (90), a band (61) of resilient material to hold the sheath (80) to the colonoscope (2) during introduction of the colonoscope (2) with the insertion device (82) mounted thereto into a colon, and an inflatable holder (81) for gripping the sheath (80) to the colonoscope (2) during insertion of the overtube (90) into the sheath (80). The holder (81) is deflated to release the grip on the colonoscope (2) and the insertion device (82) is at least partially removed from the colon after the overtube (90) has been inserted into the colon.
