Bypass grafting method which uses a number of balloon catheters to inhibit blood flow to an anastomosis site

摘要

A method of securing an end portion of a graft to a blood vessel of a patient's circulatory system during a bypass grafting procedure includes the step of inhibiting blood flow to a region of the circulatory system by inflating a number of balloons within the circulatory system, wherein a segment of the blood vessel is located in the blood flow inhibited region. The method further includes the step of creating an arteriotomy in a sidewall of the segment of the blood vessel while the number of balloons are inflated within the circulatory system. Additionally, the method includes the step of anastomosing the end portion of the graft to the segment of the blood vessel during the blood flow inhibiting step.
