The present application discloses a covered stent and a method for navigating the covered stent to a branch vessel, the covered stent comprising a main body and at least one lateral side branch connected to the main body, wherein the lateral side branch is flexible and expandable. A system of covered stents and a method for interconnecting the covered stents is also disclosed.

A sealable vascular endograft system for placement in a vascular defect includes a delivery catheter shaped to be disposed within a blood vessel. The delivery catheter includes an implant delivery catheter sheath defining an implant delivery catheter lumen and an endovascular implant removably disposed within the implant delivery catheter lumen in a compressed or folded state for delivery thereof to the vascular defect. The endovascular implant includes a tubular implant body and a sealable circumferential collar including a variable sealing device and a control lead traversing from the variable sealing device to a user and controlling variability of the variable sealing device by the user. The sealing device and the control lead cooperate to reversibly expand and contract the sealable circumferential collar to circumferentially adjust during deployment thereof to achieve a repositionable fluid-tight seal between the sealable circumferential collar and the internal walls proximal to the vascular defect.

A bifunctional expandable stent delivery assembly having a bifunctional expandable stent, a breakable cover, and a balloon. The bifunctional expandable stent has a balloon-expandable body portion and a self-expandable trumpet portion. The breakable cover fits over only the self-expandable trumpet portion and prevents self-expansion. The balloon is used to expand the balloon-expandable portion, which breaks the breakable cover and allows the self-expandable trumpet portion to self-expand. A method of stenting a patient using the bifunctional expandable stent delivery assembly is also provided.

The present invention comprises a highly conformable stent graft with an optional portal for a side branch device. Said stent graft comprises a graft being supported by a stent, wherein said stent comprises undulations each which comprise apices in opposing first and second directions and a tape member attached to said stent and to said graft such that the tape member edge is aligned to the edge of the apices in the first direction of the each of the undulations, thus confining the apices in the first direction of the undulations to the graft and wherein the apices in the second direction of the undulation are not confined relative to the graft; wherein said graft forms unidirectional pleats where longitudinally compressed and wherein said apices in the first direction of said undulation is positioned under an adjacent pleat when compressed. The invention also discloses and claims methods of making and using said highly conformable stent graft and method of making the optional portal.

A handle assembly for a prosthesis delivery device is disclosed. The handle assembly comprises a stationary main handle having a proximal end and a distal end and an outer surface extending therebetween. A first helical groove is formed in at least a portion of the outer surface of the main handle and a first trigger wire actuation mechanism disposed about the main handle and rotatably moveable relative to the main handle. A first trigger wire is operatively connected to the first trigger wire actuation mechanism, the first trigger wire having a prosthesis capture condition and a prosthesis release condition. Movement of the first trigger wire actuation mechanism causes movement of the first trigger wire thereby moving the first trigger wire from the prosthesis capture condition to the prosthesis release condition. Additional trigger wire actuation mechanisms operatively connected to one or more additional trigger wires may also be disposed about the main handle.

A device and method for repair of a patient's aorta is disclosed. The device includes a first component including an outer diameter equal to a first diameter, a second component attached to a distal end of the first component, and a plurality of third components positioned in a chamber defined in the second component. The second component includes a proximal surface extending outwardly from the distal end of the first component, and a plurality of openings defined in the proximal surface. Each third component includes a passageway extending inwardly from an opening of the plurality of openings defined in the proximal surface. Each passageway is sized to receive a tubular conduit, and the proximal surface has an outer edge that defines a second diameter greater than the first diameter.

A stent delivery system includes a self expanding stent positioned about a distal support segment of a catheter, which includes a proximal segment. A constraint has a wrapped configuration, which has a hollow elongated shape, and an unwrapped configuration, which is a continuous length of a strip. The stent is in contact with, and held in a compressed state by, the constraint in the wrapped configuration, and the stent is in an expanded state out of contact with the constraint in the unwrapped configuration. The constraint may move from the wrapped configuration toward the unwrapped configuration responsive to tension in a control line connected to one end of the strip.
