Abstract
An integrated anastomosis tool may include an effector that both makes an opening in the wall of a target vessel and connects a graft vessel to the target vessel. The effector may include a cutter assembly and a connection module that are independently actuatable. The connection between the graft vessel and the target vessel may be compliant, and may be achieved by suturing an end of the graft vessel to the side of the target vessel with the connection module.
Claims15
A surgical method for connecting a graft vessel having a lumen therethrough to a target vessel having a lumen therethrough, where both the graft vessel wall and the target vessel wall provide natural hemostasis relative to blood flowing therethrough, the method comprising:
- providing an integrated anastomosis tool;
- moving said integrated anastomosis tool into proximity with the target vessel;
- creating only a single opening in the target vessel wall with said integrated anastomosis tool;
- placing the end of the graft vessel in proximity to the single opening in the target vessel wall such that the end of the graft vessel defines a perimeter around the single opening in the target vessel wall;
- suturing the end of the graft vessel to the side of the target vessel with said integrated anastomosis tool such that fluid can flow through the single opening in the target vessel wall into the lumen of the graft vessel, and such that hemostasis is substantially restored;
- maintaining the graft vessel completely outside of the single opening in the target vessel during said placing and said suturing;
- and
- withdrawing said integrated anastomosis tool away from the target vessel, wherein during said withdrawing the entirety of said integrated anastomosis tool is maintained outside the lumen of the graft vessel.
