  • Blood vessel occlusion means suitable for use in anastomosis
    Patent number: 4168708
    Abstract: A T-shaped blood vessel occluder has a stem with a pair of opposing arms at one end forming a bar. Generally conically shaped solid bulbs are connected to the extremities of the bar. The occluder is insertable through an incision in the blood vessel with the arms and bulbs extending in opposite directions along the vessel. A section of the blood vessel is thus sealed off at both ends for anastomosis for other purposes.
