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.
Claims22
A catheter assembly for use in catheter procedures comprising:
- a generally elongate shaft formed of a polymeric layer having a proximal end and a distal end, with a lumen extending longitudinally between the proximal end and the distal end;
- and
- means insertable within the lumen of sufficient outside diameter for continual slidable contact with the shaft, thereby supporting and guiding the shaft during catheter placement.
A catheter assembly for use in catheter procedures comprising:
- a generally elongate shaft formed of a polymeric layer having a proximal end and a distal end, with a lumen extending longitudinally between the proximal end and the distal;
- means positioned over the shaft having a lumen of sufficient inside diameter for supporting the shaft during catheter placement;
- and
- means for securing the proximal end of the shaft to a proximal end of the means for supporting the shaft during catheter placement.
A method of supporting a catheter for positioning the catheter within a patient's vascular system, the method comprising:
- providing an elongate shaft including a core having a nonmetallic coating;
- inserting the shaft within the patient's vascular system;
- advancing an elongate tubular member formed of a polymeric layer over the shaft, the shaft being of sufficient outside diameter for continual slidable contact with the tubular member, thereby supporting and guiding the tubular member;
- positioning a distal end of the tubular member within the patient's vascular system.
A method of supporting a catheter for positioning the catheter within a patient's vascular system, the method comprising:
- providing a first elongate tubular member;
- inserting the first elongate tubular member within a second elongate tubular member to form a catheter assembly, wherein the first elongate tubular member is of a sufficient outside diameter for continual slidable contact with the second elongate tubular member, thereby supporting and guiding the second elongate tubular member within the catheter assembly;
- inserting the catheter assembly within a patient's vascular system;
- and
- positioning a distal end of the catheter assembly within the patient's vascular system.
