SYSTEMS, APPARATUS, AND METHODS FOR PLACING A GUIDEWIRE FOR A JEJUNOSTOMY TUBE

Devices, systems, and methods for guidewire placement for a jejunostomy tube are described herein. A system can include an elongated tube having a first end, a second end, and an engagement portion at the first end configured for engagement with an endoscope. An inflatable member can be coupled to the elongated tube and configured to transition from an uninflated configuration to an inflated configuration. A magnetic member can be coupled to the elongated tube and configured such that, in response to disposing an external magnetic assembly on a surface of the abdomen of the patient, the inflatable member can be urged against an inner surface of a jejunum wall of the patient such that any intervening structure between the surface of the abdomen of the patient and the inner surface of the jejunum wall is disposed between the external magnetic assembly and the inflatable member with substantially no fluid gaps.
