NAVIGATION ENABLED LEAD DELIVERY CATHETER
First Claim
1. A catheter system for positioning of a medical instrument, the catheter system comprising:
- a first elongate member that includes a first lumen;
a second elongate member that includes a second lumen that receives the medical instrument, the second elongate member being coupled directly to the first elongate member, the second elongate member being cuttable to allow removal of the medical instrument from the second lumen, the second elongate member being selectively collapsible and expandable to change a size of the second lumen; and
a navigation tool operable for allowing detection of a location of the catheter system, the navigation tool being received in the first lumen, wherein the second elongate member is cuttable without cutting the first elongate member and the navigation tool.

Abstract
A catheter system for positioning of a medical instrument includes a first elongate member having a first lumen. The 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 cuttable to allow removal of the medical instrument from the second lumen. The second elongate member is also selectively collapsible and expandable to change a size of the second lumen. Furthermore, the system includes a navigation tool operable for allowing detection of a location of the catheter system. The navigation tool is received in the first lumen, and the second elongate member is cuttable without cutting the first elongate member and the navigation tool.

14. A method of manufacturing a catheter system comprising:
-
directly coupling an outer surface of a first elongate member having a first lumen to an outer surface of a second elongate member having a second lumen such that a longitudinal axis of the first elongate member extends substantially in the same direction as a longitudinal axis of the second elongate member; reducing a size of the second elongate member from an expanded state to a collapsed state to reduce a size of the second lumen; and retaining the second elongate member in the collapsed state. - View Dependent Claims (15, 16, 17, 18, 19)

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, the navigation tool including an electrically conductive coil in which a current is induced in the presence of an electromagnetic field, the current being dependent on the location of the catheter system; 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 cuttable generally along a second longitudinal axis thereof to allow removal of the medical instrument from the second lumen, wherein the second elongate member is cuttable without cutting the first elongate member, the reinforcing member, and the navigation tool, 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.

21. A method of positioning a medical instrument comprising:
-
positioning a catheter system in a patient, the catheter system including a first elongate member that includes a first lumen and a second elongate member that includes a second lumen, the second elongate member being coupled directly to the first elongate member; expanding the second elongate member to increase a size of the second lumen; extending the medical instrument into the second lumen; and segmenting the second elongate member to move the medical instrument outside the second lumen. - View Dependent Claims (22, 23, 24, 25, 26)
