Abstract: A stent for use in a medical procedure having opposing sets of curved apices, where the curved section of one set of apices has a radius of curvature that is greater than the curved section of the other set of apices. One or more such stents may be attached to a graft material for use in endovascular treatment of, for example, aneurysm, thoracic dissection, or other body vessel condition.

Abstract: An implantable medical device (30) for treating aortic dissections includes a stent graft part (34) having a bulbous section (48) of greater radial diameter than the radial diameter of first and second sections (60,62) of the stent graft part (34). The bulbous section (48) is able to close off the false lumen (10) of an aortic dissection, thereby to prevent any fluid backflow into the false lumen (10). Radiopaque markers (70) may be provided for orientation and deployment purposes. The device (30) is able to treat chronic dissections and reduce false lumen backflow, which remains otherwise an unresolved issue in the endovascular treatment of false lumen aneurysms.

Abstract: A delivery system for an occlusion balloon includes a delivery catheter and a balloon releasably detached thereto. The balloon can include a base portion that is threaded onto the end of the delivery catheter. The balloon can include a one-way valve or septum in the base portion, through which a filling needle is inserted into a cavity of the balloon. The balloon can be filled with a fluid to expand the balloon and fix the balloon within the patient's body. The balloon can be filled with a hardening material to assist in fixing the balloon in place and occluding the blood vessel. The balloon can include anchoring structure on its outer surface to assist in the fixing the location of the balloon. The delivery device and needle can be detached and withdrawn from the balloon, allowing the septum to close and seal the balloon, leaving the balloon fixed within the body vessel.

Abstract: A stent graft delivery device that is pre-loaded with a single guide wire for both tracking the device within a main vessel as well as for cannulating one or more branch vessels is described. The delivery device comprises a delivery catheter having a prosthesis releasably secured thereto and a nose cone extending from the proximal end of the catheter. In a delivery configuration, a secondary catheter is coaxial with the guide wire and extends through at least a portion of the prosthesis lumen and is held within a channel formed in the nose cone. In a released configuration, secondary catheter and guide wire are retracted distally out of the channel formed in the sidewall of the nose cone dilator and can be manipulated for cannulating a branch vessel.

Abstract: A pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. The indwelling guide wire are configured to receive the access sheaths. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate catheterization of a side branch or target vessel through the fenestration or be used to stabilize the access sheath during catheterization, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.

Abstract: An implantable medical device includes a support structure which is twistable in a longitudinal direction of the device. A sleeve of filter or occluding material is attached to the ends of the structure. The structure in practice twists on itself in the longitudinal direction, causing the sleeve to twist on itself and as a result to close the lumen through the sleeve. The device provides reliable closure and as a result occlusion of a vessel. It is also able to be delivered over a guide wire. In another embodiment, the support structure includes a wire which coils around the sleeve to constrict the sleeve and as a result to close a lumen of the sleeve.

Abstract: An introducer assembly includes a distal sheath and a proximal sheath. A splitting element is located at a proximal end of the distal sheath and is arranged to split the distal sheath in a distal direction, so as to deploy first a branch element of a medical device and thereafter the distal end of the medical device. The proximal sheath can then be retracted to release the proximal end of the medical device. Deployment of the medical device from the branch element first enables accurate positioning of the branch element prior to deployment of the main body portion of the medical device.

Abstract: A pre-loaded stent graft delivery device and stent graft, the stent graft delivery device. The stent graft has at least one fenestration or side arm and the fenestration is preloaded with an indwelling guide wire. Indwelling access sheaths are provided within auxiliary lumens of a pusher catheter and dilators are preloaded into the access sheaths along with the indwelling guide wire. A handle assembly at a distal end of the guide wire catheter. The handle includes a multiport manifold with access ports to the auxiliary lumens in the pusher catheter. Upon deployment of the stent graft into the vasculature of a patient, the indwelling guide wire can be used to facilitate cathertisation of a side branch or target vessel through the fenestration or be used to stabilise the access sheath during catheterisation, advancement of the access sheath into the target vessel and deployment of a covered or uncovered stent therein through the access sheath.
