A fenestrated graft deployment system, with a delivery catheter having a catheter body, a first fenestration alignment device, and an endoluminal prosthesis having a main graft body having a lumen therethrough and a first opening laterally therein. The first fenestration alignment device is configured to extend through at least a portion of the delivery catheter and is configured to be axially moveable relative to the first guidewire. The first fenestration alignment device can cause the main graft body adjacent to the first opening to move with the end of the first fenestration alignment device to allow an operator to align the first opening in the side of the endoluminal prosthesis with an ostium of a target branch vessel into which said first opening is to extend and act as a guide and seal for a subsequently delivered branch graft endoluminal prosthesis.

Apparatus and method of placement of a graft or graft system

A complex coil and a fixture for forming same configured such that loops are formed having various configurations relative to each other. The configurations provide improved thrombus formation and reduced rotation or tumbling once implanted. The complex coil is formed of a material that may deformed for purposes of placing the complex coil into a catheter and returns to a complex shape that includes said loops once deployed.

Embolectomy catheters, rapid exchange microcatheters, systems and methods for removing clots or other obstructive matter (e.g., thrombus, thromboemboli, embolic fragments of atherosclerotic plaque, foreign objects, etc.) from blood vessels. This invention is particularly useable for percutaneous removal of thromboemboli or other obstructive matter from small blood vessels of the brain, during an evolving stroke or period of cerebral ischemia. In some embodiments, the embolectomy catheters of this invention are advanceable with or over a guidewire which has been pre-inserted through or around the clot. Also, in some embodiments, the embolectomy catheters include clot removal devices which are deployable from the catheter after the catheter has been advanced at least partially through the clot. The clot removal device may include a deployable wire nest that is designed to prevent a blood clot from passing therethrough. The delivery catheter may include telescoping inner and outer tubes, with the clot removal device being radially constrained by the outer tube. Retraction of the outer tube removes the constraint on the clot removal device and permits it to expand to its deployed configuration. An infusion guidewire is particularly useful in conjunction with the embolectomy catheter, and permits infusion of medicaments or visualization fluids distal to the clot.

A resheathing apparatus for a tube that is insertable through an endovascular catheter includes a guide that has a proximal end, a distal end, at least one lumen extending from the proximal end to the distal end, and a branch extending away from the lumen at one end of the guide. A sheath may be placed over the tube by sliding the resheathing apparatus along the length of the tube. The resheathing apparatus may also include a guide tube that fits over the branch of the guide and directs a sheath over the tube that is insertable through an endovascular catheter. The resheathing apparatus may be used with vascular embolization devices, and may be used with devices that are delivered via microcatheter systems. Methods of using the resheathing apparatus are also disclosed.
