    摘要: A method for the treatment of a stenosis or an occlusion in a blood vessel in which an occlusive device is first delivered and activated at a site distal to the occlusion to at least partially occlude the vessel. A therapy catheter is then introduced to treat the occlusion and a debris removal device is delivered to aspirate debris from the vessel. The present invention eliminates the need for a separate irrigation catheter and irrigation fluid which allows the procedure to be performed quickly and efficiently, and is especially useful in the removal of occlusion from saphenous vein graft, the coronary and carotid arteries, arteries above the aortic arch and vessels of similar size and pressure.

    摘要: The present invention provides an improved core wire for use in a medical catheter. In one aspect, the invention provides a core wire with a shapeable tip and method of manufacturing the same. A core wire previously made superelastic is subject to additional processing to remove its superelasticity thereby allowing the material to be shapeable to aid in advancing the core wire through a blood vessel or other body cavities. In another aspect of the present invention, a method is provided for securing the core wire to the distal end of an elongated catheter tubular body. The tubular body is mechanically crimped onto the core wire to secure the core wire in place. This crimping method has been found to increase the strength of the bond between the core wire and the catheter tube so that greater pull force is required to break the core wire off from the catheter.

    摘要: Disclosed herein is an improved core wire for use in a medical catheter. In one aspect, a tapering core wire is incorporated into the distal end of a catheter. The catheter has a tubular body. Both ends of an inflatable balloon are mounted to the tubular body. The core wire extends from the distal end of the tubular body. In one embodiment, substantially all of the taper of the core wire occurs in the extending portion of the core wire over a length of at least 15 mm but no more than 60 mm. In another aspect, a core wire with a shapeable tip and method of manufacturing the same are provided. A core wire previously made superelastic is subject to additional processing to remove its superelasticity thereby allowing the material to be shapeable to aid in advancing the core wire through a blood vessel or other body cavities. In another aspect of the present invention, a method is provided for securing the core wire to the distal end of an elongated catheter tubular body. The tubular body is mechanically crimped onto the core wire to secure the core wire in place. This crimping method has been found to increase the strength of the bond between the core wire and the catheter tube so that greater pull force is required to break the core wire off from the catheter.

    摘要: A dilatation or other similar catheter for intraluminal use which has an elongated shaft and an inflatable member or section on the distal extremity of the catheter shaft which has multiple working sections, a first working section which elastically expands upon inflation to a first pressure within a first pressure range and a second working section which elastically expands upon inflation to a second pressure within a second pressure range which is at least in part higher than the first pressure range. The first working section may be inflated to secure the catheter within the body lumen and then the second working section may be inflated to dilatate the body lumen.

    摘要: The mechanical properties of various angioplastic surgical devices are altered in order to enhance their transportability through the vascular system by changing their operating temperature while situated within the body. Temperature increases are utilized to increase flexibility or cause devices to assume certain configurations while a temperature decrease serves to increase stiffness and rupture strength.
