Abstract: The present invention provides a system and method for creating a percutaneous fluidic connection. In one embodiment, the system includes an endoscope having an end cap with a tube that defines a distal cavity and an internal magnet circumferentially arranged around the distal end of the tube. The internal magnet is delivered into the patient's stomach and pressed against an inner wall of the stomach. An external magnet is placed on an external surface of the patient's skin corresponding to the location of the internal magnet and the inner and external magnets are coupled together. An incision is made through the skin to access the distal cavity, and an overtube containing a PEG device is inserted into the distal cavity. The magnets are decoupled and removed, leaving the overtube in place, which is subsequently retracted from the PEG device, allowing the PEG device to be anchored in place.

Abstract: The present invention provides devices for creating an external percutaneous fluidic connections. In one embodiment, a needle is configured for extending through an endoscope. The needle includes a distal sharp tip and a lumen extending therethrough. The needle extends out of the endoscope within a body cavity to create an incision through a patient's skin. A safety cap is attached over the distal sharp tip without occluding the needle lumen. A wire is inserted through the needle lumen such that it extends from outside the body at the incision, through the body, and outside the body at the patient's mouth. After removing the needle and the endoscope from the body, a PEG device is coupled to the wire at the patient's mouth, and the PEG device is delivered through the upper GI tract and out through the incision.

Abstract: A percutaneous gastrostomy introduction system may include may include an elongate tube assembly including one or both of a dilator portion and a gastrostomy tube portion, which may be continuously formed or joined by one or more connection joints that may—in certain embodiments—provide for rotation about a common longitudinal axis. The dilator portion includes a helical surface for advancing contact with body tissue and may be disposed near (including up to and defining) a first end of the elongate tube assembly. An engagement structure, including—for example—one or more of a wire loop, a user-graspable handle, or another graspable structure may be included at the first end of the device. Device embodiments may be effective to lessen or prevent tenting of patient tissue during introduction.
