In some aspects, the disclosure provides arrangements that align a covering material of a stent graft with an opening in the vessel wall before, during, and/or after expansion of the stent graft within the vasculature of a patient. In some instances, systems and devices include a sheath with a side aperture arranged to align a portion of the sheath and/or a portion of a stent graft contained within the sheath with the mouth of an aneurysm. Similarly, the present disclosure also provides embodiments in which the stent graft comprises an aligning member arranged to align the stent graft and/or a sheath with the mouth of an aneurysm. Other embodiments are disclosed. ## Claims ### Claim 1 A system for delivering a stent graft within vasculature of a patient, comprising: a delivery member, a stent graft, and an aligning member; said stent graft having a supporting structure expandable between a first configuration arranged for delivery of said stent graft with the delivery member and a second configuration arranged for deployment in a vessel; said stent graft having a covering material extending along a portion of said stent graft; said aligning member coupled to said stent graft and extending from an area of said stent graft covered by said covering material; wherein said delivery member comprises a sheath having a distal end region, a proximal end region, and a sidewall extending between said distal and proximal end regions; said sidewall defining a lumen extending along a length of said sheath and a side aperture extending through said sidewall and communicating with said lumen; said side aperture arranged to slidably receive said aligning member; said stent graft slidably positioned within said lumen; said side aperture having a portion positioned proximally of said distal end region of said sheath; wherein said side aperture is a slot extending along a length of said sheath; wherein said slot comprises a distal slot end and a proximal slot end and tapers inwardly along a length of said slot starting from said distal slot end and extending towards said proximal slot end; wherein a first portion of said sidewall extends along a first side of said lumen and a second portion of said sidewall extends along a second side of said lumen opposite said first side; wherein said distal slot end is defined by said first portion of said sidewall; and wherein a distal surface of said second portion is distal of said distal slot end and curves in a concave direction towards said proximal end region. ### Claim 2 (depends on 1) The system of claim 1, wherein: said aligning member comprises a wire guide slidably extending through a portion of said stent graft. ### Claim 3 (depends on 2) The system of claim 2, wherein: said aligning member extends through an opening in said covering material. ### Claim 4 (depends on 3) The system of claim 3, wherein: said opening is defined by separable, overlapping portions of said covering material; and wherein said overlapping portions include a first overlapping edge portion extending over a second overlapping edge portion and said aligning member extends between said first and second overlapping edge portions. ### Claim 5 (depends on 2) The system of claim 2, wherein: said delivery member and said wire guide are arranged to rotate at least a portion of said delivery member within the vessel of the patient so as to align said covering material of said stent graft with an opening in a vessel wall. ### Claim 6 (depends on 2) The device of claim 2, comprising a wire guide diverting member positioned within the lumen of the sheath, the wire guide diverting member comprising an arcuate surface arranged to divert portions of the wire guide through a side of the stent graft. ### Claim 7 (depends on 1) The system of claim 1, wherein: said aligning member is fixedly coupled to said stent graft and is arranged to extend away from said stent graft. ### Claim 8 (depends on 1) The device of claim 1, wherein the slot is tapered along the entire length extending from the distal slot end to the proximal slot end. ### Claim 9 (depends on 1) The device of claim 1, wherein the sheath has a rounded distal tip. ### Claim 10 (depends on 1) The device of claim 1, wherein said distal slot end is at least twice as wide as said proximal slot end. ### Claim 11 A device for deploying a stent within the vasculature of a patient, comprising: a sheath having a distal end region, a proximal end region, and a sidewall extending between said distal and proximal end regions; said sidewall defining a lumen extending along a length of said sheath and a side aperture extending through said sidewall and communicating with said lumen; said side aperture having a portion positioned proximally of said distal end region of said sheath; wherein said sheath is arranged to retain a stent for delivery within the vasculature of the patient; wherein said side aperture is arranged to slidably receive an aligning member; wherein said side aperture is a slot extending along a length of said sheath; and wherein said slot comprises a distal slot end and a proximal slot end and tapers inwardly along a length of said slot starting from said distal slot end and extending towards said proximal slot end; wherein a first portion of said sidewall extends along a first side of said lumen and a second portion of said sidewall extends along a second side of said lumen opposite said first side; wherein said distal slot end is defined by said first portion of said sidewall; and wherein a distal surface of said second portion is distal of said distal slot end and curves in a concave direction towards said proximal end region. ### Claim 12 (depends on 11) The device of claim 11, wherein: said side aperture is arranged to slidably receive an aligning member comprising a wire guide. ### Claim 13 (depends on 11) The device of claim 11, wherein the slot is tapered along the entire length extending from the distal slot end to the proximal slot end. ### Claim 14 (depends on 11) The device of claim 11, comprising a wire guide diverting member positioned within the lumen of the sheath, the wire guide diverting member comprising an arcuate surface arranged to divert portions of a wire guide through the slot. ### Claim 15 (depends on 11) The device of claim 11, wherein the sheath has a rounded distal tip. ### Claim 16 (depends on 11) The device of claim 11, wherein said distal slot end is at least twice as wide as said proximal slot end. ### Claim 17 A device for deploying a stent within the vasculature of a patient, comprising: a sheath having a longitudinal axis, a distal end region, a proximal end region, and a sidewall extending between said distal and proximal end regions; said sidewall defining a lumen extending along a length of said sheath and a side aperture extending through said sidewall and communicating with said lumen; said side aperture having a portion positioned proximally of said distal end region of said sheath; wherein said sheath is arranged to retain a stent for delivery within the vasculature of the patient; wherein said side aperture is arranged to slidably receive an aligning member; wherein said slot comprises a distal slot end and a proximal slot end and tapers inwardly along a length of said slot starting from said distal slot end and extending towards said proximal slot end; and wherein said distal slot end is at least twice as wide as said proximal slot end.
