Systems, apparatus, and methods for placing a guidewire for a gastrostomy tube

A method, comprising:

• translating an inflatable member of an elongated tube through an orifice of a patient and to a first location within the patient;
• inflating the inflatable member via a lumen of the elongated tube such that the inflatable member transitions from an uninflated configuration to an inflated configuration;
• inserting a first end of a needle through a tissue wall of the patient and through a sidewall of the inflatable member;
• translating a coupling member of a guidewire assembly through the tissue wall of the patient at least partially through a lumen of the needle to a second location within the patient near the first location, the guidewire assembly including a guidewire having a first end coupled to the coupling member and a second end disposed outside the patient, the guidewire extending through the tissue wall;
• coupling the coupling member to the inflatable member;
• and
• withdrawing the elongated tube through the orifice such that the coupling member and the first end of the guidewire are withdrawn from the orifice and such that the guidewire extends through the orifice, the first location, and the tissue wall of the patient and the second end of the guidewire is disposed outside of the patient.
