Abstract
Guide catheter incorporating a braidless construction having increased performance characteristics for catheterization procedures. The guide catheter may include a tracking wire, inner or outer guide for positioning the guide catheter within the patient's vascular system.
Claims26
A catheter assembly for use in catheter procedures, comprising:
- a guide catheter comprising a braidless shaft, wherein the shaft comprises a proximal end, a distal end, and a lumen extending longitudinally therethrough, the guide catheter sized to extend within the vasculature from an entry location in the femoral artery to a blood vessel in the upper abdomen of a human patient;
- an inner guide member comprising an elongate shaft, wherein the elongate shaft comprises a proximal end, a distal end, and a lumen extending longitudinally therethrough;
- and
- the inner guide member is adapted for insertion within the lumen of the guide catheter, thereby supporting the guide catheter shaft during catheter placement.

- wherein the shaft comprises a polymer layer and a lubricous inner coating;
- an inner guide member comprising an elongate shaft, wherein the elongate shaft comprises a proximal end, a distal end, and a lumen extending longitudinally therethrough;
- and
- the inner guide member is adapted for insertion within the lumen of the guide catheter, thereby supporting the guide catheter shaft during catheter placement, wherein the lubricous inner coating allows for near frictionless movement of the inner guide member within the guide catheter lumen.
2 more elements
A method of supporting a catheter for positioning the catheter within a patient's vascular system, the method comprising:
- providing a catheter assembly, the catheter assembly including a guide catheter comprising a shaft, wherein the shaft comprises a proximal end, a distal end, and a lumen extending longitudinally therethrough, wherein the shaft comprises a polymer layer and a lubricous inner coating;
- an inner guide member comprising an elongate shaft, wherein the elongate shaft comprises a proximal end, a distal end, and a lumen extending longitudinally therethrough;
- and the inner guide member is adapted for insertion within the lumen of the guide catheter, thereby supporting the guide catheter shaft during catheter placement, wherein the lubricous inner coating allows for near frictionless movement of the inner guide member within the guide catheter lumen;
- inserting the inner guide member within the patient's vascular system;
- advancing the guide catheter over the inner guide member, the inner guide member being of sufficient outside diameter for continual slidable contact with the guide catheter, thereby supporting and guiding the guide catheter;
- and
- positioning the distal end of the guide catheter within the patient's vascular system.
