Abstract:
In at least one embodiment of the present invention, an access sheath for positioning in a patient's body is provided. The access sheath comprises an elongated member having a proximal portion extending to a distal portion and a plurality of lumens formed therethrough including a working lumen and a first additional lumen. The first additional lumen is configured to receive an optical system or an irrigation system. The proximal portion has a stiffening section that includes a first coil and one of a braiding and a second coil which are disposed about the working lumen in concentric relationship with each other. The distal portion has a tip and a first deflection section and a second deflection section. The first deflection section is proximal to the tip and distal to the second deflection section. The first deflection section is configured to be actuated to bend at a first angle to position the tip. The second deflection section is configured to bend at a second angle to reposition the tip.
