摘要： A steerable guide wire includes a core wire having a proximal end and a distal end. A braided filament is affixed to the distal end of the core wire. An outer coil surrounds at least a portion of the core wire and the braided filament. A proximal end of the braided filament is secured to a distal end of the coil. By locating the braided filament in the distal tip portion of the guide wire, a guide wire is provided that is highly flexible, has a high degree of tensile integrity, and is highly steerable, even in tortuous vasculature. Filter and balloon catheters having braided filaments at the distal end are also described.

摘要： A wire control catheter for aligning and guiding a guide wire through a lesion in a vessel is provided. The wire control catheter includes a shaft having a guide wire lumen and a control wire lumen. A control wire passes through the control wire lumen and is used in combination with an articulation structure to deflect or curve a distal tip portion of the catheter. The distal catheter shaft may include a centering device for centering the catheter within the vessel. The distal catheter shaft also may include a pre-dilation balloon for dilating the lesion prior to performing angioplasty or other treatment on the lesion. Additionally, a sliding sheath catheter may be used to provide additional support to the guide wire. The sliding sheath catheter is sized to fit within the guide wire lumen of the control catheter and to allow the guide wire to pass through it. A method of treatment of a blood vessel includes inserting a guide wire into the blood vessel and advancing a control catheter over the guide wire until the distal tip of catheter is near the occlusion in the blood vessel. The tip of the catheter then is deflected via a control wire and an articulation structure. The guide wire is then advanced across the occlusion. The control catheter also may be advanced across the occlusion simultaneously with the guide wire or subsequent to the guide wire crossing. Prior to crossing the occlusion, the wire control catheter may be centered using a centering device. Subsequent to crossing the occlusion, the occlusion may be pre-dilated with a pre-dilation balloon of the wire control catheter.

摘要： An evacuation sheath assembly and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. The evacuation sheath assembly includes an elongated tube defining an evacuation lumen having proximal and distal ends. A proximal sealing surface is provided on a proximal portion of the tube and is configured to form a seal with a lumen of a guided catheter. A distal sealing surface is provided on a distal portion of the tube and is configured to form a seal with a blood vessel. Obturator assemblies and infusion catheter assemblies are provided to be used with the evacuation sheath assembly. A method of treatment of a blood vessel using the evacuation sheath assembly includes advancing the evacuation sheath assembly into the blood vessel through a guide catheter. Normal antegrade blood flow in the blood vessel proximate to the stenosis is stopped and the stenosis is treated. Retrograde blood flow is induced within the blood vessel to carry embolic material dislodged during treating into the evacuation sheath assembly. If necessary to increase retrograde flow, the coronary sinus may be at least partially occluded. Alternatively, antegrade flow may be permitted while flow is occluded at the treatment site.

摘要： A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating an endoscope lumen through the balloon dilation catheter.
