摘要：
Methods, devices, apparatus, assemblies, and kits for performing a vascular anastomosis are disclosed. A device for a vascular anastomosis includes tissue engaging portions that can move between at least two configurations. In some embodiments, the tissue engaging portions move without the aid of moving parts, while in other embodiments the tissue engaging portions extend from one or more movable wings. The tissue engaging portions may be separated by a first distance when in a pre-deployment configuration and by a second distance when in a deployed configuration. A method includes engaging a plurality of tissue engaging members of a coupling device against first end tissue. After selectively engaging the tissue engaging members and first end tissue, the first end tissue is stretched by at least moving the tissue engaging members. The stretched first end tissue is coupled to the second end tissue by mating the coupling device to a mating anastomosis device.
