    摘要: The present embodiments provide apparatus suitable for treating a medical condition at a target site. In one embodiment, the apparatus comprises a plurality of strands, each having proximal and distal regions, wherein the plurality of strands are twisted in a generally helical manner to form a tubular shape. The proximal and distal regions of each of the plurality of strands comprise a contracted configuration adapted for delivery to the target site. Further, the distal region of at least one of the plurality of strands comprises an expanded, radially deployed configuration adapted to facilitate treatment of the medical condition. The distal region of at least one of the plurality of strands may be deployed in a self-expanding or balloon-expandable manner.

    摘要: Embolectomy procedures can be performed under conditions to effectively remove thrombus/emboli with little risk of injuring the vessel wall and while effectively capturing and removing emboli. Desired embolectomy devices present a polymer matrix against the vessel wall. Suction can be used to facilitate the embolectomy process and to remove emboli loosened in the procedure. Some devices combine features to present a polymer matrix against the vessel wall while corresponding providing sufficient support to effectively loosen thrombus. Combinations of embolectomy and/or filter elements can be used.

    摘要: An apparatus and system for removing an obstruction from a body lumen simultaneously mechanically dislodges the obstruction, macerates the obstruction, and aspirates the effluent caused thereby. The maceration is effected by directing pressurized fluid to the obstruction, while the obstruction is dislodged by a tip portion formed on the end of a guidewire. The apparatus includes a flexible catheter having at least two channels individually accommodating fluid flow paths towards and away from the obstruction. The guidewire may be disposed in either of the channels or a third channel formed in the flexible catheter. The apparatus also includes a drive unit for rotating the guidewire. The drive unit may be an external drive unit, such as an electrical motor, or may include drive elements formed on the guidewire within a drive chamber, across which the fluid flows and imparts energy against the drive elements to cause rotation of the guidewire.
