Claim 0:
1. A system for creating an arteriovenous fistula in a patient, the system comprising:
a vascular implant; and
a delivery device for delivering the implant between a first vessel and a second vessel, comprising:
an outer sheath configured to constrain the implant in a low-profile configuration at a distal end of the outer sheath; and
a nose cone comprising a proximal end and a distal end and a cavity, wherein the distal end of the outer sheath is insertable into the cavity to position a distal segment of the implant at least partially within the cavity for advancement of the nose cone, the distal end of the outer sheath, and the distal segment of the implant through the first vessel and into the second vessel;
wherein the proximal end of the nose cone is at an angle relative to a longitudinal length of the nose cone to define an inclined opening into the cavity, wherein the angled proximal end of the nose cone is configured to engage a near wall of the second vessel after the nose cone is advanced into the second vessel;
wherein the outer sheath is retractable in a proximal direction relative to the nose cone to expand the distal segment of the implant within the cavity;
wherein the outer sheath is further retractable in the proximal direction relative to the nose cone to expand a proximal segment of the implant at least partially within the first vessel; and
wherein the nose cone is distally advanceable relative to the distal segment of the implant after the proximal segment is expanded at least partially within the first vessel to release the distal segment of the implant from the cavity within the second vessel.
