<p>An inflatable stent (10) is provided for placement within the biliary duct to facilitate drainage therethrough and maintain the patency of the duct. The biliary stent includes a tubular member (12), an inflatable reservoir (30) and a port (40) located at a proximal portion (20) of the tubular member. The tubular member has interior (16) and exterior (18) surfaces and an inflatable reservoir disposed circumferentially between the interior and exterior surfaces. An inflation fluid, such as a liquid or gas, may be inserted through the port and contained within the inflatable reservoir to expand the diameter of the biliary stent. The biliary stent may be removed from the patient by deflating the inflatable reservoir and using a removal device such as a forceps or snare.</p> |
