A tubular suturing device for suturing new types of tubular connectors to the ends of tubular structures such as blood vessels. The suturing device comprises a substantially rigid body containing multiple staples disposed within receptacles arranged radially along a suturing surface of the body, and an actuating mechanism moving in predetermined spaces producing multiple forces ejecting the staples in an approximately radial direction. Various embodiments and methods are provided for attachment of different types of tubular connectors to the external or internal surface of the tubular structures by staples ejected in an inward or outward radial direction; for new methods of clinching of the prongs of the ejected staples; for new surgical procedures and for new instruments facilitating their performance.
