Stent devices and methods to increase patency of a body opening

A stoma device configured for deployment in a stoma, said stoma stent comprising:

• a radially-expandable stent
• having a retention member disposed on an end thereof;
• wherein said retention member is configured to be placed external to the stoma and sized and shaped and further configured to cover the stoma and to adapt said stoma device for use in the stoma.

A method of inhibiting migration of a stoma, said method comprising:

• inserting a stoma device, having a radially-expandable saddle region and a retention member disposed on one end of the saddle region, into the stoma, the stoma device movable between an unexpanded configuration, with a compressed diameter sized to pass into the stoma, and an expanded configuration with an expanded diameter larger than the compressed diameter and sized to support the stoma;
• and
• selecting the stoma device to exert a radially-expansive force on the stoma to retain the stoma device in place relative to the stoma to prevent migration of both the stoma device and the stoma.
