Abstract
An endovascular implant for forming a fistula includes a body including a wall forming a lumen having a distal opening and a proximal opening. An anchor is coupled to a distal end of the body adjacent the distal opening. The anchor may include a first anchor extending from a first side of a distal end of the body, and a second, separate anchor may extending from a second side of the distal end of the body. A retriever may be coupled to a proximal end of the body adjacent the proximal opening.

An endovascular implant for forming a fistula, comprising:
- a body including a wall forming a lumen, the body including a distal end having a distal opening and a proximal end having a proximal opening;
- and
- an anchor coupled to a distal end of the body adjacent the distal opening, the anchor including a first anchor extending from a first side of a distal end of the body, and a second anchor extending from a second side of the distal end of the body, the second anchor separated from the first anchor;
- and
- a single retriever formed by a pair of interconnected hooks having a juxtaposed, abutting relationship.
An endovascular implant for forming a fistula, comprising:
- a body including a wall forming a lumen, the body including a distal end having a distal opening and a proximal end having a proximal opening;
- and
- an anchor coupled to the distal end of the body adjacent the distal opening,
- a retriever coupled to the proximal end of the body adjacent the proximal opening, the retriever formed by a pair of interconnected hooks having a first longitudinal portion including a partial twist.
An endovascular implant for forming a fistula, comprising:
- a body including a wall forming a lumen, the body including a distal end having a distal opening and a proximal end having a proximal opening;
- an anchor coupled to a distal end of the body adjacent the distal opening, the anchor including a first anchor extending from a first side of a distal end of the body, and a second anchor extending from a second side of the distal end of the body, the second anchor separated from the first anchor;
- and
- a retriever comprising a pair of hooks bonded together by a weld in a juxtaposed, abutting relationship each hook of the pair of hooks having a first longitudinal portion extending from and unitarily formed with the wall and a second portion connected to the first longitudinal portion, each hook being formed of the material of the wall having the thickness.
