Endoscopic bypass grafting method utilizing an inguinal approach
First Claim
1. A method for connecting a graft conduit to the aorta in a patient'"'"'s body, the method comprising:
- forming an incision in the body of the patient to expose a femoral artery;
extending upwardly through the incision toward the aorta an elongated surgical instrument including a lumen therein between distal and proximal ends thereof;
performing an aortotomy at a site along the aorta through the lumen of the surgical instrument;
positioning one end of the graft conduit at the site through the lumen of the surgical instrument;
forming an anastomosis of the one end of the graft conduit with the aorta at the site of the aortotomy; and
attaching another end of the graft conduit to a blood vessel in the body of the patient.

Abstract
A method for implanting an end portion of a graft within the body of a patient during a bypass grafting procedure is disclosed. The body has a circulatory system which includes a femoral artery and an aorta. The method includes the steps of (i) making an incision in the body of the patient so as to expose the femoral artery and an inguinal ligament, (ii) advancing an endoscope between the femoral artery and the inguinal ligament until a distal end of the endoscope is positioned at a working site within the body, (iii) advancing the end portion of the graft between the femoral artery and the inguinal ligament to the working site, wherein said end portion advancing step includes the step of advancing the end portion of the graft through the endoscope, and (iv) forming an anastomosis between the end portion of the graft and the aorta at the working site.

2. A method for connecting to the aorta in a patient'"'"'s body a graft conduit including a body portion and an end portion, the method comprising:
-
forming an incision in the body of the patient to expose a femoral artery; extending through the incision toward the aorta an elongated surgical instrument including a lumen therein between distal and proximal ends thereof; performing an aortotomy at a site along the aorta through the lumen of the surgical instrument; collapsing the graft conduit to dimension smaller than the cross-sectional dimension of the lumen of the surgical instrument; positioning one end of the graft conduit at the site through the lumen of the surgical instrument; expanding the end portion of the graft conduit into contact with the walls of the aorta to secure the body portion of the graft conduit in position through the aortotomy; forming an anastomosis of the one end of the graft conduit with the aorta at the site of the aortotomy with the end portion positioned along the aorta and with the body portion protruding through the aortotomy; attaching the end portion of the graft conduit to the aorta with the body portion protruding outside the aorta; and attaching another end of the graft conduit to a blood vessel in the body of the patient. - View Dependent Claims (3)
