WOUND CLOSURE DEVICE AND METHOD

摘要

An apparatus and method are provided for closing a perforation in a wall of a patient's blood vessel or other organs. The apparatus includes an elongated support member having a distal end supporting one or more tissue engaging hooks configured to engage fibrous vessel tissue when moved in a first direction and to disengage the tissue when moved in a second direction, and a proximal end for applying rotational torque to the support member to cause the hooks to engage collagen fibrous tissue in the adventitia of the blood vessel or fibrous tissue in other body organs. The hooks engaging the collagen fiber causes the blood vessel tissue surrounding the perforation to be drawn into close proximity such that the perforation can be closed. The apparatus is deployed in an outer sheath with the hooks encased until a selected engaging location has been achieved. Puncture closure can be accomplished by various techniques, including stasis, cauterizing, or by clamping.
