An endoprosthetic device comprises a tubular main body having a length including proximal and distal portions, the tubular main body having a flexible portion between the proximal and distal portions, and at least one adjustable length docking branch extending laterally from the tubular main body, and having sections bearing a tab or loop graspable by a user, and optionally further having at least one auxiliary branch, and at least one access branch, for assembly with at least one tubular branch body having a laterally extending access branch, using a delivery system including a delivery shaft, and a retrieval capsule and corresponding press-fit retrieval pin and retrieval wire, wherein the delivery shaft is provided with a pivotal slotted housing serving as a user handle for the delivery shaft.

Aneurysms are treated by placing a scaffold across an aneurysmal sac to provide a blood flow lumen therethrough. An aneurysmal space surrounding the scaffold is filled with one or more expandable structures which are simultaneously or sequentially expanded to fill the aneurysmal space and reduce the risk of endoluminal leaks and scaffold migration. The expandable structures are typically inflatable and delivered by delivery catheter, optionally with an inflation tube or structure attached to the expandable structure.

A stent graft for placement in a vessel of a patient, the stent graft that has a tubular body of graft material, the tubular body having a proximal inflow end, a distal outflow end, a main lumen therethrough, a longitudinal access, and a sidewall from the first end to the second end. At least one stent is along the length of the tubular body. One or more shaped recesses are formed of a concave or recessed portion of graft material that extends into the lumen of the stent graft. A fenestration is in the recessed portion with a fenestration and an internal branch extends from the or each fenestration toward the proximal end of the tubular body of graft material. The internal branch may have a tubular portion and a funnel portion, wherein the tubular portion extends into the main lumen and the enlarged funnel portion is attached to sidewall and forms the at least one shaped recess.

Apparatus for progressively dilating the lumen of a narrow natural vessel such as an iliac artery and implanting a tubular device enabling access through the dilated lumen to conduct subsequent procedures via the dilated lumen, includes an inflatable integrated balloon locatable at least partially within the tubular device, the tubular device having a length L1 providing a self-expanding tubular body having at least a portion including stents, so that when the integrated balloon is removed the dilated lumen of the natural vessel remains dilated and supported by the tubular device.

Systems and methods for repairing aneurysms (e.g., abdominal aneurysm) are provided. The systems and methods provide stent-graft systems having a first stent and a main graft body wherein the main graft body is configured to be inserted through a blood vessel located above a diaphragm of the patient into a target blood vessel. In some instances, the first stent and the main graft body can be in a substantially end-to-end configuration. In some instances, the stent-graft systems and methods are configured for use in a single arterial puncture or incision in, for example, a blood vessel with a diameter less than or equal to the diameter of a femoral artery from the same patient or subject.

Controlled deployable medical devices that are retained inside a body passage and in one particular application to vascular devices used in repairing arterial dilations, e.g., aneurysms. Such devices can be adjusted during deployment, thereby allowing at least one of a longitudinal or radial re-positioning, resulting in precise alignment of the device to an implant target site.
