Removal tool for use with endoscopic device
A system for use with an endoscopic device. The system can include a shaft having a proximal end, a distal end, and at least one output port, wherein a portion of the shaft is surrounded by a single polyurethane expandable material, wherein the polyurethane expandable material is expandable from a diameter of at least approximately 5.0 mm to a diameter of approximately 25 mm. The system can also include a manifold connected to the proximal end of the shaft, the manifold including one or more fluid coupling ports for receiving an injected fluid, wherein at least one of the one or more fluid coupling ports is in fluid communication with the at least one output port and wherein when received, the system is configured to convey the injected fluid from the manifold to the shaft resulting, at least in part, in expanding the polyurethane expandable material.
1. A system for use with an endoscopic device, comprising:
a shaft having a proximal end, a distal end, and at least one output port, wherein a portion of the shaft is surrounded by a single polyurethane expandable material, wherein the polyurethane expandable material is expandable from a diameter of at least approximately 5.0 mm to a diameter of approximately 25 mm; and
a manifold connected to the proximal end of the shaft, the manifold comprising one or more fluid coupling ports for receiving an injected fluid, wherein at least one of the one or more fluid coupling ports is in fluid communication with the at least one output port and wherein when received, the system is configured to convey the injected fluid from the manifold to the shaft resulting, at least in part, in expanding the polyurethane expandable material.
2. The system of claim 1 , wherein each of the one or more fluid coupling ports is in fluid communication with only one of the at least one output port.
3. The system of claim 1 , wherein the shaft comprises a plurality of output ports comprising a distal output port, medial output port, and proximal output port.
4. The system of claim 3 , wherein the polyurethane expandable material is positioned over the medial output port.
5. The system of claim 3 , wherein the shaft is configured to convey fluoroscopic contrast dye to the distal output port.
6. The system of claim 3 , wherein the shaft is configured to convey fluoroscopic contrast dye to the proximal output port.
7. The system of claim 1 , wherein the injected fluid comprises a saline solution.
8. The system of claim 1 , wherein the shaft comprises a polyurethane material, and wherein a portion of the polyurethane expandable material is fused to the polyurethane material of said shaft.
9. The system of claim 1 , wherein the shaft comprises a polyolefin strain relief sheath.
10. The system of claim 1 , wherein at least a portion of the polyurethane expandable material comprises a cross-linked material.
