Method for the percutaneous suturing of a vascular puncture site

A method of suturing a puncture site in a blood vessel wall, the method comprising:

• positioning a length of suture into a lumen of the blood vessel;
• forming at least two penetrations in the blood vessel wall at the end of a tissue tract adjacent the puncture site with more than one needle;
• passing a first end of a length of suture through one of the penetrations outwardly from the lumen and a second end of the length of suture through another penetration outwardly from the lumen with the needles;
• and
• securing the first and second ends of the suture to close the aperture.

A method for suturing vascular tissue, the method comprising:

• forming at least two penetrations in one or more layers of vascular tissue at the end of a tissue tract with more than one needle;
• passing a first end of a length of suture through one of the penetrations and a second end of the length of suture through the other penetration with the needles;
• and
• securing the first and second ends of the suture to pull the penetrations in one or more layers of vascular tissue together.

A method for suturing vascular tissue having a distal side and a proximal side, the method comprising:

• penetrating a layer of vascular tissue at the end of a tissue tract with at least one needle;
• drawing a length of suture proximally through the penetration with the needle;
• and
• detaching the length of suture from the needle to free the length of suture for fastening to the same length.
