<p>The application addresses the need for novel hemostatic clips that are used advantageously when control of a vessel has not been obtained or when a vessel is lacerated or divided inadvertently. These clips urge closure of a perforation in the wall of a vessel, and reduce the necessity for suturing the vessel. In addition, the disclosure addresses the need for a hemostatic clip that can be used to efficiently ligate a severed vessel. The invention provides a hemostatic clip for closing a perforation in the wall of a vessel. The clip has a unitary clip body that defines an annular strip formed in a saddle shape to adapt to the walls of the vessel. In a further aspect, the invention provides a hemostatic clip for ligating a severed vessel which has a unitary clip body that defines side by side and opposed pad members. An arcuate link member joins between and interconnects the pad members to clamp the lumen of a severed vessel closed. In a still further aspect, hemostatic clips are disclosed that can be applied by endoscopic methods through surgical access ports that dictate that the clip applicator approach the vessel parallel rather than normal to the longitudinal access of the vessel.</p> |
