Abstract
Provided herein are novel devices for the formation of arteriovenous fistulas, which may aid subjects in need of hemodialysis. The novel devices are provided in a non-surgical procedure, greatly decreasing the cost and increasing the convenience of placing an arteriovenous fistula. The devices are atraumatic, and consist of a sutureless anastomosis device and conduit. Methods and tools for placing the devices in vivo are disclosed, including a magnetic-assisted method.
Claims15
A method of bringing into contact a wall of a first blood vessel and a wall of a second blood vessel in a subject, the method comprising:
- advancing a first catheter having a magnetized end face through the first vessel to a target site;
- advancing a second catheter having a magnetized end face through the second vessel to the target site, wherein magnetic attraction between the magnetized end faces of the first and second catheters brings a wall of the first blood vessel into contact with a wall of the second blood vessel at the target site, wherein the first blood vessel is a deep artery and the second blood vessel is a superficial vein.
