Abstract
A catheter system for positioning of a medical instrument that includes a first elongate member having a first lumen. The catheter system also includes a second elongate member that includes a second lumen that receives the medical instrument. The second elongate member is coupled directly to the first elongate member, and the second elongate member is operable to be at least partially segmented generally along a second longitudinal axis thereof to allow movement of the medical instrument outside the second lumen. The second elongate member is selectively collapsible and expandable to change a size of the second lumen.

20. A catheter system for positioning of a medical instrument, the catheter system comprising:
-
a first elongate member that includes a first lumen and an outer surface; a reinforcing member that reinforces the first elongate member; a navigation tool with an electrically conductive coil operable for detecting a location of the catheter system, the navigation tool being received in the first lumen; a second elongate member that includes a second lumen that receives the medical instrument and an outer surface, the outer surface of the second elongate member being longitudinally coupled directly to the outer surface of the first elongate member, the second elongate member operable to be at least partially segmented generally along a second longitudinal axis thereof to allow movement of the medical instrument outside the second lumen, the second elongate member being selectively collapsible and expandable to change a size of the second lumen; and a port member having a first port in fluid communication with the first lumen and a second port in fluid communication with the second lumen, the navigation tool extending through the first port and into the first lumen, and the medical instrument extendable through the second port and into the second lumen.
