Claims8
A method for implanting a prosthetic device in a body comprising:
- placing a first suture through tissue at a first position using a first needle of a suture system;
- placing a second needle of a suture system having an associated double stranded suture in the tissue at a distance from the first position, different strands having different indicators such that the different strands can be identified;
- placing additional sutures using additional needles through the tissue;
- placing the first suture through a cuff of the prosthetic device using the single-threaded needle of the suture system;
- placing the second needle and an associated double-stranded suture in the prosthetic device;
- placing additional sutures using additional double-stranded sutures along the prosthetic device;
- and
- securing the prosthetic device into position.
