  • Patent number: 11452590
    Abstract: A stent graft (2) for placement in the thoracic arch of a patient has a first tubular body portion (6) with a first lumen therein for placement in the ascending aorta of a patient and a second tubular body portion (8) to extend along the thoracic arch and down the descending aorta. The second tubular body portion is of a lesser diameter than the first tubular body portion. There is a step portion (10) between the first body portion and the second body portion. The step portion is joined to and continuous with the first portion and the second portion. A first side of each of the first body portion, the step portion and the second body portion are substantially aligned so that there is a step (18) defined on a second side opposite to the first side of the body portion. There is an aperture (30) in the step portion and an internal tube (32) extending from the aperture towards the first body portion.

  • Patent number: 10143576
    Abstract: A stent graft has a tubular body with a first bifurcation with first and second legs extending from the bifurcation. One of the legs has a further bifurcation to define a side arm. The stent graft can be deployed into the vasculature of a patient with the tubular body being in an aorta of the patient, a first leg extending down an iliac artery, a second leg being directed towards a contralateral iliac artery and the side arm directed to an internal artery of one of the iliac arteries. One of the legs can include a valved aperture to enable the placement of an indwelling catheter therethrough.

  • Patent number: 9833345
    Abstract: The present embodiments provide a stent for use in a medical procedure that comprises a series of proximal apices disposed at a proximal end of the stent and a series of distal apices disposed at a distal end of the stent. In a first embodiment, a first proximal apex comprises a bore for receiving a trigger wire, and a second proximal apex, disposed adjacent to the first proximal apex, comprises at least one barb. In an alternative embodiment, a first proximal apex comprises a first bore and a second, adjacent proximal apex comprises a second bore, such that a single trigger wire may be disposed through the first and second bores to restrain the first and second proximal apices during delivery.

  • Patent number: 9504555
    Abstract: A method of assembling of a stent graft (20) including temporarily diameter reduction arrangements to enable partial release of a stent graft to assist with positioning before complete release. The diameter reduction arrangement includes a release wire (72) and flexible threads (74, 80) extending to struts (76) of a self expanding stent (70) either side of the release wire and being pulled tight. Removal of the release wire enables full expansion of the self expanding stent.
