20160100969 | STENT GRAFT - A stent graft comprises a hollow cylindrical body and a sleeve catheter, wherein the body comprises at least a self-expanding stent and prosthetic material, wherein the body has a circumference in a compressed state which is smaller than a circumference of the body in an expanded state. The sleeve catheter is embodied as a flap-shaped compression element comprising two longitudinal edges, wherein a first longitudinal edge is attached to the body, wherein an extent of the flap-shaped compression element perpendicular to the first longitudinal edge is smaller than the circumference of the body in the expanded state, wherein, for compressing the body, the flap-shaped compression element can be placed around the body and a free second longitudinal edge is detachably fixable to fixation points arranged on the body and/or on the flap-shaped compression element. | 04-14-2016 |
20160051387 | PUSHER-ASSEMBLY FOR AN INSERTION SYSTEM FOR A SELF-EXPANDABLE VASCULAR IMPLANT - The invention relates to a pusher assembly for an insertion system for a vascular implant. The pusher assembly has a catheter tube. The catheter tube has a tubular cavity for accommodating a guide wire and has a proximal catheter tube segment and a distal catheter tube segment adjoining the proximal catheter tube segment. The distal catheter tube segment is provided at least partially for movably accommodating a vascular implant on the distal catheter tube segment. The catheter tube also has a pusher unit for releasing the vascular implant, said pusher unit being proximally adjacent to a vascular implant loaded onto catheter tube. The pusher assembly is characterized in that the pusher unit is formed by individual, segment-like elements, which are arranged on behind the other and adjacent to each other and are arranged on the catheter tube in order to proximally adjoin the vascular implant. | 02-25-2016 |
20150250629 | VASCULAR IMPLANT WITH ASYMMETRICAL STENT SPRINGS - The invention relates to a self-expanding vascular implant for implanting into a blood vessel, the implant comprising a hollow cylindrical body with a proximal and a distal end and with a longitudinal axis; comprising stent springs, which are successively arranged and spaced from one another over the longitudinal axis of the body, each stent spring meandering; and comprising an implant material, which is fixed to the stent springs and connects same. The stent springs have pointed arches which alternately point toward the proximal and distal direction and comprise alternating crests and troughs that are connected to one another via legs of different lengths, whereby a stent spring has pointed arches, which are circumferentially and successively arranged and which have different heights, said pointed arches consisting of higher and shorter pointed arches. | 09-10-2015 |
20150250626 | VASCULAR IMPLANT WITH SIDE BRANCH - The present invention relates to a self-expanding vascular implant for implanting into a blood vessel of a patient. The vascular implant has a main body and at least one side body, and has integrally formed, one-piece stent springs, which are successively arranged in the longitudinal axis of the main body, with each stent spring meandering perpendicular to the longitudinal axis, and an implant material which is fixed to and connects the stent springs. The stent springs have pointed arches that alternately point toward the proximal end and the distal end of the main body and parallel to the longitudinal axis thereof. The at least one side body that branches off from the main body is, in the self-expanded state, set out at an angle relative to the longitudinal axis of the main body. | 09-10-2015 |
20120150273 | ONE-PIECE BIFURCATION GRAFT - The present invention relates to an endoluminal prosthesis to be deployed at a vessel bifurcation, comprising a one-piece graft sleeve with a branching portion, defining a first prosthesis lumen and having, in its deployed state, a first diameter, said branching portion being reinforced by stent elements, and a trunk portion, defining a second prosthesis lumen in fluid communication with said first prosthesis lumen and having, in its deployed state, a second diameter. Said trunk portion is essentially free from reinforcing stent-material (FIG. | 06-14-2012 |
20090216307 | BRAIDED STENT TO BE IMPLANTED IN A BLOOD VESSEL - A braided stent to be implanted in a blood vessel comprises a hollow body which is stretchable in its longitudinal direction and whose circumferential surface is formed by a braid of a multiplicity of filamentary elements which, in the expanded state of the braided stent, intersect a plane, perpendicular to the longitudinal direction, at a braiding angle. The braided stent has a smaller braiding angle in a central portion than in its distal and proximal portions which adjoin the central portion in the longitudinal direction. | 08-27-2009 |
