The application of a tensile force at least partially straightens the serpentine fibrils, thereby elongating the article. The expanded polytetrafluoroethylene membrane may include a microstructure of substantially only fibrils. The articles can be elongated to a predetermined point at which further elongation is inhibited by a dramatic increase in stiffness. In one embodiment, the articles are used to form a covered stent device that requires little force to distend in the radial direction to a first diameter but is highly resistant to further distension to a second diameter (stop point). A large increase in diameter can advantageously be achieved prior to reaching the stop point.07-18-2013
20120290069PARAPLEGIA PREVENTION VALVE FOR STENT GRAFTS - A stent graft defining a main lumen bounded by a wall of graft material is disclosed. The stent graft has a valve portion between proximal and distal portions. The valve portion is formed by a wall portion having a part-circumferential double layer portion comprising an inner underlap portion and an outer overlap portion, the double layer portion forming a passageway parallel to the main lumen. The passageway has an entrance mouth and an exit mouth. The passageway has an open condition where the underlap and overlap portions are spaced apart to form a vent lumen. The wall portion is broken by a narrow cut. The cut is openable by relative radial movement between its edges. This allows re-perfusion of an aneurism and perfusion of blood from within the lumen out towards blood vessels such as intercostals and can assist in minimising the chance of paraplegia.11-15-2012
20120290068STEERABLE ILIAC BRANCH DEVICE - A prosthesis may be used for treatment of an aneurysmal body vessel. The prosthesis may include a prosthetic trunk and a prosthetic branch. The prosthetic trunk may include a graft body, an open first end, an open second end, and a trunk lumen extending therebetween. The prosthetic branch may include a graft body, an open first end, an open second end, and a branch lumen extending therebetween. The first end of the prosthetic branch may be attached to the prosthetic trunk, and the branch lumen may be in fluid communication with the trunk lumen. The prosthetic branch may be movable in relation to the prosthetic trunk between neutral, right biased, and left biased configurations. First and second releasable steering members may be associated with the respective first and second biased configurations and may cooperatively retain the prosthetic branch in the neutral configuration.11-15-2012
20120029611Stent Graft System and Method of Use - A stent graft system and method of use including a stent graft system with a first stent graft component and a second stent graft component. A first tubular graft of the first stent graft component has an integral first body and first leg, with the first body defining a first crown opening and a first substantially elliptical opening. The second body of the second stent graft component is disposed in the first body of the first stent graft component with the second leg of the second stent graft component disposed through the first substantially elliptical opening of the first stent graft component with the perimeter of the first elliptical opening of the first stent graft component in contact with the second body of the second stent graft component.02-02-2012
20120296414THORACIC AORTA STENT GRAFT - A stent graft for placement in the thoracic arch of a patient has a tubular body defining a main lumen therethrough, a plurality of zig zag stents along the tubular body, each of the stents comprising a plurality of struts and bends, the bends being between adjacent struts. At least a first stent and an adjacent second stent having at least a pair of adjacent bends on the first stent aligned with an adjacent pair of bends on the second stent, whereby a first pair of adjacent struts of the first stent and a second pair of adjacent struts of the second adjacent stent together define a diamond shape region. A recess is within the diamond shaped region with the recess extending into the lumen of the tubular body. A fenestration extending into the tubular body within the recess in the diamond shaped region and a graft tube leading from the fenestration into the main lumen. There can be one, two or three diamond shaped regions, recesses, fenestrations and graft tubes Proximally of the or each diamond shaped region the tubular body has a first diameter, distally of the diamond shaped region the tubular body has a second diameter and in the region of the tubular body around the diamond shaped region the tubular body has a third diameter, the first diameter being greater than the second diameter and both the first and second diameter being greater than the third diameter whereby a central region is defined which will allow circumferential blood flow during an operation out of the graft tube into the recess and then into the central region.11-22-2012
20130103135FENESTRATED INFLATABLE GRAFT - The endovascular graft includes a tubular structure having a first end and a second end. The tubular structure has a wall which defines a lumen between the first and second ends. A fenestration is located between the first and second ends to extend through the wall of the tubular structure. A sealing ring is circumferentially disposed within or on, including without limitation secured to, the tubular structure. The sealing ring is adjacent to the fenestration. The sealing ring may be inflatable.04-25-2013
20130204347LATTICE - The invention relates to medical devices and methods of using them. The devices are prostheses which can be percutaneously deliverable with (or on) an endovascular catheter or via other surgical or other techniques and then expanded. The prostheses are configured to have a lattice resistant to dilation and creep, which is defined by a plurality of openings. The prosthesis may also optionally have a stent disposed proximal to the lattice. In exemplary embodiments, the fluoropolymer is expanded polytetrafluoroethylene. The composite materials exhibit high elongation while substantially retaining the strength properties of the fluoropolymer membrane. In at least one embodiment, the lattice is made of a composite material that includes a least one fluoropolymer membrane including serpentine fibrils and an elastomer. A lattice including a generally tubular member formed of a composite material including a least one fluoropolymer membrane containing serpentine fibrils and an elastomer is also provided.08-08-2013
