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.

Claims

1. A method for implanting an end portion of a graft within the body of a patient during a bypass grafting procedure using an elongated medical instrument having a lumen therein, the body having a circulatory system which includes a femoral artery and an aorta, the method comprising:

making an incision in the body of the patient to expose the method artery and an inguinal ligament;

advancing the medical instrument between the femoral artery and the inguinal ligament until a distal end of the medical instrument is positioned at a working site near the aorta within the body;

advancing the end portion of the graft within the lumen of the medical instrument between the femoral artery and the inguinal ligament to the working site; and

forming an anastomosis between the end portion of the graft and the aorta at the working site.

2. A method of implanting an end portion of a graft within the body of a patient during a bypass grafting procedure using a tubular medical instrument, the body having a circulatory system which includes a femoral artery and an aorta, the method comprising:

making an incision in the body to expose the femoral artery at least below the inguinal ligament.

positioning the medical instrument within the body with a distat end of the medical instrument positioned at a working site near the aora and with a proximal end of the medical instrument positioned outside of the body, and with an intermediate portion of the medical instrument interposed between the femoral artery and the inguinal ligament;

advancing the end portion of the graft through the medical instrument to the working site near the aorta; and

thereafter forming an anastomosis between the end portion of the graft and the aorta.

3. The method of claim 2, wherein:

the medical instrument is an endoscope having a lumen therein, and

advancing the end portion includes advancing the end portion of the graft through the lumen in the endoscope to the working site near the aorta.

4. The method of claim 2,

forming the anastomosis includes establishing fluid communication between the end portion of the graft and the aorta.

5. A method of delivering an implantable medical apparatus to a working site near the aorta within the body of a patient during a medical procedure using a medical instrument, the method comprising:

positioning the medical instrument within the body with a distal end of the medical instrument positioned at the working site near the aorta, and with an intermediate portion of the medical instrument interposed between the femoral artery and the inguinal ligament; and

advancing the implantable medical apparatus through the medical instrument to the working site near the aorta.

6. The method of claim 5, wherein the implantable medical apparatus includes an end portion of a graft.
