Abstract
A trocar useful for forming an incision in a target vessel for placement of an anastomosis device which may have an inner flange formed by radial expansion of the device and an outer flange formed by axial compression of the device. The trocar can have a smaller size during formation of the incision and a larger size when retracted over a deployment tool used to deploy the anastomosis device.
