Multi-lumen shaft used with endoscopic device
Briefly, in accordance with one embodiment, a multi-lumen shaft may be used to with an endoscopic instrument.
1. A method of dislodging an object behind an ostium, comprising:
inserting a multi-lumen shaft into a duct and a location distal to the object;
inflating an expandable vessel, coupled to multi-lumen shaft, until the expandable vessel approaches a threshold volume;
dispensing a fluoroscopic contrast dye through a port of the multi-lumen shaft at a location proximal to the expandable vessel; and
dispensing a fluoroscopic contrast dye through a port of the multi-lumen shaft at a location distal to the expandable vessel.
2. The method of claim 1 , further comprising the step of drawing the multi-lumen shaft towards the ostium until the object passes the ostium.
3. The method of claim 1 , wherein the step of inflating of the expandable vessel comprises dispensing a saline solution to the expandable vessel.
4. The method of claim 1 , wherein the expandable vessel is composed of polyurethane.
5. The method of claim 1 , wherein the step of inflating of the expandable vessel in a duct will block fluid communication in the duct between the port of the multi-lumen shaft at a location proximal to the polyurethane expandable vessel and the port of the multi-lumen shaft at a location distal to the polyurethane expandable vessel.
