  • Catheter having oval aspiration lumen and method of making
    Patent number: 8298210
    Abstract: Catheters for aspiration of thrombotic, atherosclerotic or other particulate embolic debris from a blood vessel. An elongate flexible aspiration tube has an aspiration lumen defined by a reinforced tube wall. A guidewire tube is secured alongside the aspiration tube extending proximally from a distal end thereof to define either over-the-wire or single operator catheter configurations. The portion of the aspiration tube alongside the guidewire tube has an oval transverse cross section with a minor axis extending transversely through the guidewire tube. The oval cross section of the aspiration tube improves the catheter's efficient use of cross sectional space by making the overall catheter transverse cross section nearly equal in orthogonal dimensions. Methods of making aspiration catheters are also disclosed, including permanently deforming the portion of the aspiration tube into an oval transverse cross section.

  • Aspiration catheter with tracking portion
    Publication number: 20060041246
    Abstract: A catheter having one or more radially expanded portions that comprise a guidewire lumen. The guidewire lumen and the main lumen of the catheter are not separate and share the same fluid space. The catheter maintains a large, circular lumen for aspiration or delivery. The catheter is made by lacing a guidewire lumen mandrel through openings made in the catheter shaft and then forcing the shaft to expand radially to create a guidewire lumen.
