Abstract: In some embodiments, a system or apparatus includes an elongated tubular member having a first end and a second end. The elongated tubular member defines a first lumen extending from the first end to the second end, and a second lumen extending from a first port, which is defined in a sidewall of the elongated tubular member, to a second port in the second end of the elongated tubular member. An inflatable member is coupled to the elongated tubular member. The inflatable member is configured to define an echogenic volume in an inflated condition. A magnetic member is disposed within the elongated tubular member. A position of the inflatable member and the first end of the elongated tubular member within a cavity of a patient can be controllable via magnetic attraction between the magnet and an external magnetic source disposed external to the patient.

Abstract: 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.

Abstract: Devices, systems, and methods for guidewire placement for a gastrostomy tube are described herein. A system can include an elongated tube, an inflatable member, and a guidewire assembly. The elongated tube can have a first end, a second end, and can define a lumen. The inflatable member can be coupled to the first end of the elongated tube and can be fluidically coupled to the lumen such that the inflatable member can receive fluid via the lumen. The guidewire assembly can include a guidewire having a first end and a second end. The first end of the guidewire assembly can include a coupling member, the coupling member configured to couple to the inflatable member such that translation of the elongated tube translates the guidewire assembly.

Abstract: Devices, systems, and methods for creating a percutaneous tracheostomy are described herein. In some embodiments, a system can include an inflation assembly and a guidewire assembly. The inflation assembly can include an elongated tube, an inflatable member, and a magnetic member. The elongated tube can have a first end, a second end, and can define a lumen. The inflatable member can be coupled to the first end of the elongated tube and can be fluidically coupled to the lumen such that the inflatable member can receive fluid via the lumen. The magnetic member can be coupled to the first end of the elongated tube. The first end of a guidewire of the guidewire assembly can include a coupling member, the coupling member configured to couple to the inflatable member such that translation of the elongated tube translates the guidewire assembly.
