STERILE TRANSCOLONIC ACCESS DEVICE

摘要

Devices and methods useful for translumenally accessing a body cavity are disclosed. In one embodiment, a translumenal access device adapted to be inserted through a body lumen is provided and can include an inner shaft having an opening at its distal end and adapted to be positioned adjacent to an inner wall of a body lumen. The inner shaft can include one or more sealing mechanisms, such as one or more seals with suction ports formed thereon for isolating a portion of a body lumen. The isolated portion may be sterilized and serve as an access point or otomy site for penetrating the wall of the body lumen to access a body cavity.
