Methods and devices are provided for providing sterilize access to a body cavity through the wall of a body lumen. In one exemplary embodiment, a translumenal access device is provided having an outer elongate tubular member with an attachment housing located on a distal end thereof and adapted to form a seal with a tissue wall. The device can further include an inner sheath extending through a passageway of the outer elongate tubular member and adapted to isolate the sealed region of the tissue wall from the inner lumen in the elongate tubular member. The inner sheath can be removably mated to the device to allow any bacteria present within the sheath to be removed from the device after the sealed region of tissue is sterilized. The tubular member will be thus provide a sterile pathway which can be used to access a body cavity through the sealed tissue region. |
