Rotatable connection between an intervention member and a manipulation member of an endovascular device

A medical device for removal of an occlusive thrombus from a blood vessel, the device comprising:

• an elongate manipulation member having a first connection member proximate a distal end of the elongate manipulation member;
• and
• an intervention member having a self-expanding structure and a second connection member, the self-expanding structure having a plurality of cells, the self-expanding structure 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 plurality of cells sized to penetrate into and capture thrombus upon expansion to the expanded configuration;
• and
• a third connection member connected to the first connection member and the second connection member such that the first connection member can rotate relative to the second connection member without deformation of any of the first connection member, the second connection member, or the third connection member,
• wherein the first connection member comprises a first loop, the second connection member comprises a second loop, and the third connection member comprises a third loop substantially permanently interlinked with the first loop and the second loop,
• wherein the first loop, then second loop, and the third loop comprising rigid materials, and
• wherein in the expanded configuration, the intervention member has a diameter than is greater than a maximum diameter of the elongate manipulation member.
