    Abstract: A medical device configured to perform an endovascular therapy can include an elongate manipulation member and an intervention member. The elongate manipulation member can include a distal end portion. The intervention member can include a proximal end portion and a mesh. The proximal end portion can be coupled with the distal end portion of the elongate manipulation member. The mesh can have a plurality of cells in a tubular configuration and being compressible to a collapsed configuration for delivery to an endovascular treatment site through a catheter and being self-expandable from the collapsed configuration to an expanded configuration. The mesh can include an anodic metal and a cathodic metal. The anodic metal and the cathodic metal can each form a fraction of a total surface area of the mesh.

    Abstract: Retrieval of material from vessel lumens can be improved by use of a distal element comprising an expandable mesh. a treatment device includes an elongated member having a proximal portion and a distal portion configured to be positioned within a blood vessel at a treatment site at or near a thrombus. A distal element comprising a plurality of woven filaments defining a shaft at a proximal portion and a body distal of the shaft is coupled to the distal portion of the elongated member via a connection assembly. In an expanded state, at least a portion of the distal element is configured to be in apposition with the blood vessel wall at the treatment site to anchor or stabilize the elongated member with respect to the blood vessel. The distal element can be electrically coupled to an extracorporeal current generator.
