A stent graft delivery device includes a handle body, a distal handle, a proximal handle, a guidewire lumen, a nose cone, a rigid outer catheter, a graft push lumen, a sheath lumen, an inner sheath and a locking ring. The locking ring is switchable between an advancement position and a delivery position. The stent graft delivery device is employed in methods for endovascular delivery of stent grafts.

Stent graft delivery device

A method for implanting a prosthesis centrally within a curved lumen includes loading a prosthesis into a delivery sheath, advancing the sheath in a patient towards the curved lumen to place at least the proximal end of the prosthesis within the curved lumen, and centering the proximal end of the prosthesis and/or the distal end of the sheath within the curved lumen. In a first advancing step, the outer catheter containing the inner sheath is advanced together towards the curved lumen to a location proximal of the curved lumen and, in a second advancing step, the inner sheath containing the prosthesis is advanced into the curved lumen to place at least the proximal end within the curved lumen while the outer catheter substantially remains at the location. After centering, the proximal end of the prosthesis is deployed centered within the curved lumen.

Delivery system and method for self-centering a proximal end of a stent graft

A delivery system for delivering and deploying stent grafts having a proximal stent includes a first lumen and a stent capture device including a capture portion fixedly connected adjacent a first lumen distal end. An outer catheter has a catheter distal end and a catheter inner diameter. A second lumen having a second distal end is slidably disposed about the first lumen and within the outer catheter. A stent graft sheath has a sheath proximal end connected to the second distal end and disposed about the first lumen. The sheath has a sheath distal end and a sheath inner diameter greater than the catheter inner diameter for holding a compressed stent graft. A distal nose cone has a cone proximal end connected to either the capture portion or the first distal end. The nose cone and the capture portion are movably adjustable to selectively capture the sheath distal end therebetween.

Stent graft with a longitudinal support member

A system for implanting a prosthesis includes a prosthesis that extends about a major longitudinal axis and an alignment device connected to the prosthesis. The alignment device appears asymmetric across a plane coplanar to a longitudinal axis of the prosthesis when viewed both along the plane and transversely to the longitudinal axis of the prosthesis delivery and also lies in a plane parallel to and spaced apart from the longitudinal axis of the prosthesis. The alignment device is visible to a user, thereby indicating a rotational and an axial position of the prosthesis with respect to the treatment site prior to implantation of the prosthesis at a treatment site. In an embodiment, the system includes a guidewire catheter that is asymmetric along a major longitudinal axis.

Vascular repair devices

A method for automatic endovascular alignment of a prosthesis includes loading the prosthesis in a distal delivery assembly, positioning a guidewire into a curved implantation site, and threading a guidewire lumen over the guidewire with the delivery assembly and into an implantation site to at least approximately align the curved distal portion to a curve of a curved implantation site and, thereby aligning the prosthesis.

Methods of self-aligning stent grafts

A stent graft includes a graft sleeve, a bare stent and at least one stent at the proximal end of the graft sleeve distal to the bare stent. The at least one stent includes proximal apices that are nested between adjacent distal apices of the bare stent, and an amplitude defined as a distance extending along the longitudinal length of the stent graft. The at least one stent has a relaxed diameter greater than that of a diameter of the graft sleeve and is secured along its entirety to the graft sleeve. The amplitude of the at least one stent is less than that of the bare stent amplitude. An outward radial force of the at least one stent against the graft sleeve at any given diameter of the stent graft is greater than that of the bare stent. Stent grafts may be used in methods to treat vascular disease.

A system for implanting a prosthesis includes a prosthesis delivery device having a handle, an inner lumen, a nose cone, an intermediate lumen, a prosthesis sheath at the distal end of the intermediate lumen for holding therein a prosthesis to be implanted, and an outer lumen fixedly connected to the handle. The system can include a lumen control assembly operable to move the intermediate lumen with the prosthesis sheath between a retracted position and an extended position.

Sheath capture device for stent graft delivery system and method for operating same

A vascular repair device includes a tubular graft body and a structural framework having at least two stents. A first stent of the stents is connected to the tubular graft body along an entirety of the first stent and a second of the stents includes a periodically changing shape that defines proximal apices having a first radii of curvature and distal apices having a second radii of curvature that is less than the first radii of curvature. The second stent is connected to the tubular graft body at the distal apices.

A delivery system for delivering and deploying a stent graft includes a guidewire catheter, an apex release catheter, an apex capture device, a relatively rigid, hollow catheter, and a distal nose. The apex capture device includes a distal capture portion fixedly connected to the distal end of the guidewire catheter and having a distal portion and a proximal stopper having an exposed side facing distally in a plane approximately perpendicular to a longitudinal axis of the guidewire catheter. The apex capture device also includes a proximal capture portion fixedly connected to the distal end of the apex release catheter and has fingers extending toward the distal capture portion in a distal direction that define an interior cavity to receive the proximal stopper. The proximal and distal capture portions of the apex capture device define a stent capture state.
