Abstract

Methods and apparatus for delivering and installing a new length of tubing between two sections of a patient'"'"'s existing body organ tubing and at least partly outside of that existing structure. For example, the new length of tubing may be for the purpose of providing the patient with a coronary bypass. The new tubing may be an artificial graft, a natural graft (harvested elsewhere from the patient), or both. The new tubing is installed at the operative site primarily by providing at least one graft location with instrumentation inserted through the patient'"'"'s existing tubular body organ structure. Assistance in installing the new tubing may be provided by minimally invasive surgical access openings in the patient'"'"'s chest. The tubing may be delivered through the patient'"'"'s existing tubular body structure or, alternatively, through the surgical access openings.
