Devices and methods for enteral feeding

A medical device, comprising:

• an adapter including one or more passages;
• a shaft, including:
• a proximal portion coupled to the adapter,
• one or more lumens in fluid communication with the one or more passages of the adapter, and
• a distal portion;
• and
• an expandable member coupled to the distal portion of the shaft, and in fluid communication with the one or more lumens, the expandable member configured to extend at least partially into an opening in tissue, and to expand the opening when the expandable member moves from an unexpanded state to an expanded state, a portion of the expandable member having one or more markings, the one or more markings being configured to provide a visual indication of a characteristic of the opening when the expandable member extends at least partially into the opening.

A method for placing a feeding device in an opening through tissue of a patient, the method comprising:

• inserting at least a portion of an expandable member of a dilation device into the tissue opening;
• expanding the expandable member from an unexpanded state to an expanded state, to expand the tissue opening;
• comparing one or more markings on the expandable member to at least a portion of the tissue opening when the expandable member extends at least partially into the tissue opening, to obtain an indication of a characteristic of the tissue opening;
• selecting a feeding device based at least in part on the indication of the characteristic of the tissue opening;
• and
• inserting at least a portion of a tubular member of the feeding device into the tissue opening.
