摘要： A dilation catheter device and system for dilating an opening in a paranasal sinus and/or other passageways within the ear, nose or throat is disclosed. A dilation catheter device and system is constructed in a manner that facilitates ease of use by the operator and, in at least some cases, allows the dilation procedure to be performed by a single operator. Additionally, the dilation catheter device and system may be useable in conjunction with an endoscope and/or a fluoroscope to provide for easy manipulation and positioning of the devices and real time visualization of the entire procedure or selected portions thereof. In some embodiments, shaft markers are disposed on a shaft of the dilation catheter and have a light color to contrast with a dark color of the dilation catheter shaft. The high contrast between the markers and catheter shaft allows for easy viewing of the markers in low light and operation conditions.

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： Aspiration catheters and methods for the treatment of an occlusion in a blood vessel. These catheters and methods are especially useful in the removal of occlusions from saphenous vein grafts, the coronary and carotid arteries, arteries above the aortic arch and even smaller vessels. The catheters of the present invention are provided in either over-the-wire or in single operator form. Radiopaque markers are preferably incorporated into distal ends of the catheters, and visual markers are incorporated into the proximal end of the catheters, to facilitate their positioning within the body. The catheters are provided with varying flexibility along the length of the shaft, such that they are soft and flexible enough to be navigated through the vasculature of a patient without causing damage, but are stiff enough to sustain the axial push required to position the catheter properly and to sustain the aspiration pressures. Support mandrels and support sheaths may also be added to impart additional strength to the length of the catheter.
