The present invention relates to a stent device comprising a sleeve formed with a plurality of compactable spring ring elements arranged along its length, the sleeve having compacted and expanded states. Each said ring element has an undulating profile at the surface of the sleeve so that adjacent ring elements at least partially overlap along the longitudinal extent of the device, the ring elements being compactable against their natural resilience to reduce the outer diameter of the sleeve for allowing housing of the compacted stent device in a frangible sheath, with adjacent ring elements being inter-coupled so as to substantially maintain their axial spacing between the compacted and expanded states.

Stent device

A stent graft prosthesis includes a fabric sleeve supported by a series of ring stents, including ring stents having a saddle shape with peaks and valleys, the axial alignment of equivalently shaped ring stents in the series of ring stents being such that with respect to at least one shaped ring stent other shaped ring stents are angularly offset. Multiple series of ring stents may be interposed such that at least one ring stent in a first series of ring stents S-Sis located between two ring stents in at least one other series of ring stents S-S, the angular offset of ring stents in the first series S-Sbeing different from the angular offset of ring stents in at least one other series of ring stents (S-S). The offset changes the amount of fabric surface between peripheral contact points of successive shaped ring stents.

Endoprosthesis

A hybrid endoprosthetic device comprises a stented tubular part and a branched tubular body connected such that a main lumen of the stented tubular part communicates with a main lumen of the branched tubular body. The branched tubular body has multiple branch lumens for connection with natural vessels of the vasculature, and includes at least one branch lumen for access to facilitate delivery and implantation of the hybrid endoprosthetic device by an endovascular step in a hybrid surgical procedure. The hybrid endoprosthetic device is configured to replace a part of the aorta and common iliac artery. A delivery system for use with the device is also disclosed.

Hybrid prosthesis and delivery system

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 Lproviding 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.

Tubular medical device

A stent graft prosthesis includes spaced stent elements for location on a tubular graft. First and second stent elements are located in first and second locations on the graft. The second stent element includes a saddle shaped stent. The first stent element includes a ring shaped stent. Optionally a third stent element is also present. The tubular graft includes a graft sleeve. The prosthesis can be used for treatment of vascular disorders such as aortic aneurysm.
