Abstract
Implantable device embodiments, such as stents, and particularly esophageal stents, formed of a scaffolding structure are disclosed. The scaffolding structure is formed of one or more strand elements arranged in a braided pattern. A covering may coat the scaffolding structure. A valve can be secured to the scaffolding structure and/or the covering. Anti-migration features may be formed by bends in the one or more strand elements. The bends forming the anti-migration features protrude outwardly away from an outer surface of the implantable device.
Claims23
An implantable device to be disposed within a body lumen, the implantable device comprising:
- a scaffolding structure configured to provide support to the body lumen, the scaffolding defining a generally cylindrical shape and a lumen through the scaffolding structure, wherein the scaffolding structure comprises one or more strand elements braided in a braid pattern;
- and
- a valve coupled to an inside diameter of the scaffolding structure.
An implantable device to be disposed within a body lumen, the implantable device comprising:
- a scaffolding structure defining a generally cylindrical shape and a lumen through the scaffolding structure, wherein the scaffolding structure comprises one or more braided strand elements and comprises a first zone and a second zone, the second zone having a lower degree of compressibility and a higher braid angle than the first zone;
- and
- a valve coupled to an inside diameter of the second zone of the scaffolding structure.
An implantable device to be disposed within a body lumen, the implantable device comprising:
- a scaffolding structure defining a generally cylindrical shape and a lumen through the scaffolding structure, the scaffolding structure comprising one or more strand elements braided according to a braid pattern, the scaffolding structure configured in a plurality of zones;
- a reinforcement member integrated into the scaffolding structure to define a reinforced zone of the plurality of zones, the reinforced zone having a lower degree of compressibility than another zone of the plurality of zones;
- and
- a valve coupled to an inside diameter of the reinforced zone of the scaffolding structure.
