Abstract
Non-migrating stent devices and methods for using the devices are provided for treatment of visceral anastomosis strictures or vascular ostium high grade stenosis. For example, placement of a non-migrating stent may be appropriate following a surgical procedure such as hollow visceral anastomosis.
Claims25
A medical device configured to expand or fortify a stricture comprising:
- a central conduit section;
- at least one anchoring section;
- and
- at least one transitional section positioned between the conduit section and the at least one anchoring section.
1 more element
A medical device for treatment of a stricture, wherein said device can assume at least two configurations, comprising:
- a first substantially cylindrical configuration of the device, and
- a second configuration of the device wherein at least one region along the cylindrical length of the device is expanded from the initial cylindrical plane.
A method for using a medical stent device to treat a stricture, comprising:
- placing the device into the stricture in a first configuration having a first outer diameter that is relatively constant along the longitudinal axis and that allows the structure to be inserted in the stricture;
- and
- deploying the device into a second configuration having a second outer diameter that is larger than the first outer diameter, so as to secure the device in place.
