A delivery apparatus for delivering a surgical device comprising, a catheter having a distal segment, a proximate segment, and a lumen. The distal segment has a first configuration having a curved shape. A delivery component is then inserted within the lumen of the catheter where the delivery component has a first and a second segment wherein the first segment has rigidity greater than the catheter and the second segment having rigidity less than the catheter. The distal segment of the catheter is bent straight into a second configuration by the first segment of the delivery component that is more rigid than the catheter when that segment is moved along the entire distal end of the catheter. The catheter can then bend into a third configuration that is curved when the delivery component is moved so that a second segment of the delivery component comes into contact with lumen of the distal end of the catheter where the distal end of the catheter is more rigid than the second segment of the delivery component.

An insertion apparatus comprises an introducer sheath, a surgical component, at least two attachment wires, and a longitudinal wire. The insertion apparatus is used for deploying a surgical component to a site in a vessel. The introducer sheath has a lumen, a proximal opening and a distal opening with an appropriate diameter and length allowing fro insertion and navigation through the vessel. The surgical component has a tube portion with a top and at least one limb. The surgical component corresponds to the site in the vessel and fits within the lumen of the introducer sheath. The attachment wires have a first and a second end. The first end is releasably connected to the top of the surgical component and the second end converges above the top of the surgical component. The activation of a releasing mechanism releases the first end from the top of the surgical component. The longitudinal wire anchors from the second end extending through the surgical component and through the introducer sheath to the releasing mechanism outside the vessel.

Several embodiments of a penetration apparatus and methods for using the same during a surgical procedure are disclosed. The penetration apparatus comprises a thin elongated body having a first end, a second end, and a central longitudinal axis extending there between. The first end opposes the second and is aligned within a vessel matrix during the surgical procedure. The second end of the body is substantially free and may be rotated around the axis. The penetration apparatus may also be housed within a catheter that has a cavity that precisely accommodates the penetration apparatus. Activation and advancement of the penetration apparatus within the catheter forms an incision through a vessel matrix enabling the placement of a fastener or a plurality of fasteners therein.

An embodiment of the present invention relates to an apparatus and method for stabilizing a catheter during a surgical procedure. In particular, an embodiment of the present invention relates to a stabilizing surgical delivery apparatus that comprises a catheter and a plurality of micro-barbs located on an external surface of the catheter, wherein the micro-barbs are minimally exposed when the catheter is in a linear position and fully exposed when the catheter is in an articulated, non-linear position. The micro-barbs contact or may become embedded in an endolumenal surface opposite the surgical site to provide stabilization to the catheter during the surgical procedure.

The present invention depicts a method and apparatus for treating an aneurysm. The method of treating an aneurysm is to first, insert a flared stent having a lumen into an artery with the flared portion extending into the lumen of the aneurysm, second, insert a bifurcation graft through the lumen of the flared stent and attach the bifurcation graft to the artery; and finally, insert an inner stent into the lumen of the bifurcation graft.
