摘要： Methods and devices for providing temporary placement of a filter in a blood vessel are disclosed. A filter delivery system in accordance with one exemplary embodiment of the present invention includes a catheter having an elongate shaft and a tubular member disposed within a shaft lumen defined by the elongate shaft. The elongate shaft also includes a proximal end, a distal end, and a wall defining the shaft lumen. The tubular member has a first end fixed to the wall of the elongate shaft, and a second end disposed within the shaft lumen. The tubular member defines a guidewire lumen that is in fluid communication with a distal guidewire port defined by the second end of the tubular member. The catheter also includes a proximal guidewire port extending through the wall of the elongate shaft. A filter may be disposed within a distal portion of the shaft lumen. A distal end of a guidewire is fixed to the filter. The guidewire preferably extends through the distal guidewire port, the guidewire lumen, and the proximal guidewire port.

摘要： An evacuation sheath assembly and method of reducing or removing a blockage within a vessel without permitting embolization of particulate matter is provided. The evacuation sheath assembly includes a first elongate tubular member, having proximal and distal ends and a main lumen configured to be placed in fluid communication with a blood vessel. An expandable member is provided on a distal portion of the tubular member and is configured to form a seal with the blood vessel. The evacuation assembly further includes a second elongate tubular member having proximal and distal ends and an inflation lumen configured to be placed in fluid communication with the expandable member and a gas inflator. The gas inflator includes a high pressure gas source and a mechanism for regulating the pressure of the gas delivered by the gas inflator. The gas inflator is configured to be placed in fluid communication with the proximal end of the inflation lumen in order to provide a regulated pressure gas source for inflating the expandable member. 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. The expandable member is inflated to provide form a seal between the blood vessel and the guide catheter and a vacuum is applied to the main lumen of the first elongate tubular member to cause retrograde blood flow and carry fluid into the main lumen of the evacuation sheath assembly.
