1. A device for forming and/or maintaining a percutaneous access pathway into a body of a patient, comprising:
an access pathway configured to allow access to an internal portion of a patient's body from an external environment, the access pathway comprising an access pathway port configured to maintain a non-pierceable barrier between the internal portion of the body and the external environment when in a closed position, wherein the access pathway port connects through a distal opening to an access pathway catheter extending at least partially into the internal portion of the body and allowing access into the internal portion of the body when the access pathway port is open; and
an attachment device connectable to the access pathway port and configured to open the access pathway port, the attachment device comprising an internally sterile attachment device sheath at least partially surrounding an internal equipment component of the attachment device, the attachment device sheath configured to enable insertion of at least part of the internal equipment component into the internal portion of the body through the access pathway when the attachment device is connected to the access pathway port.
