Abstract

Surgical eversion apparatus for preparing a conduit for anastomosis in a human patient comprises an everting member having a loop shaped portion adapted to be inserted into an end portion of a conduit harvested from a human patient and configured to fold a portion of the conduit end portion over itself when moved proximally away from the end of the conduit and along the conduit while a portion of the conduit is held fixed relative thereto. A method of everting a graft comprises positioning a graft in a support device such that an end portion of the graft extends therefrom; introducing a generally looped shaped member into the end portion of the graft extending from said support device; and moving the looped shaped member over the support device to fold at least a portion of the end portion of the graft over the support device.

Description

FIELD OF THE INVENTION

[0001] This invention relates to apparatus and methods for preparing a tubular graft for an anastomosis procedure. More particularly, the invention involves apparatus and methods for everting a graft prior to anastomosing the graft to another tubular structure such as an aorta. BACKGROUND OF THE INVENTION

[0002] The occlusion of the arteries can lead to insufficient blood flow resulting in discomfort and risks of angina and ischemia. Significant blockage of blood flow in the coronary artery can result in damage to the myocardial tissue or death of the patient. In most cases, occlusion of the artery results from progressive long term deposits of plaque along the artery wall. While such deposits may be concentrated and occlude the artery at a particular site, the deposits are most certainly present throughout the arteries and the vascular system.

[0003] Coronary artery bypass graft (CABG) surgery is a surgical procedure performed in severe cases of coronary bloc...
