  • Guiding tool for wound closure element
    Patent number: 6712837
    Abstract: A guiding tool for controllable and reversible folding or deformation of a wound closure element before insertion into a percutaneous incision or puncture in the wall of e.g. a blood vessel, said incision or puncture being smaller than said wound closure element in an unfolded or undeformed state. It comprises a tubular member having a lumen. The lumen has inner walls provided with wound closure element guiding surfaces, adapted to reversibly reduce the spatial extension of a wound closure element during its passage through the guiding tool. A system for the introduction and securing of a wound closure element into a percutaneous incision or puncture in the wall of a vessel comprises such a guiding tool.
