The device is inserted in a vessel wall with the shank traversing an opening in the vessel with the blunt end being positioned exterior to the outer surface of the vessel and the head of the device abutting the inner surface of the vessel at the opening. The portion of the shank that projects outwards from the vessel wall is connected to one end of a flexible cannula such that the other end of the cannula can be used to access blood within the vessel. ## Claims ### Claim 1 A sterile vessel wall traversing device shaped like a blunt-ended nail and comprising a hollow shank portion, a head portion having a width larger than the width of the shank portion, and a bore extending the entire length of the shank portion, wherein the shank has a length of between about 4-12 mm and a width of between about 1-4 mm; the head has a width of between about 2-6 mm and a length between about 0.7-3 mm; and the bore has a diameter of between about 0.8-1.3 mm. ### Claim 2 (depends on 1) The sterile vessel wall traversing device of claim 1, wherein the vessel wall traversing device is reversibly attached to an applicator. ### Claim 3 (depends on 1) The sterile vessel wall traversing device of claim 1, wherein the vessel wall traversing device comprises a biocompatible plastic. ### Claim 4 (depends on 1) The sterile vessel wall traversing device of claim 1, wherein the vessel wall traversing device comprises an anti-microbial agent. ### Claim 5 (depends on 1) The sterile vessel wall traversing device of claim 1, wherein the vessel wall traversing device comprises an anti-thrombogenic agent. ### Claim 6 A kit comprising a hermetically sealed container housing a sterile vessel wall traversing device shaped like a blunt-ended nail and comprising a hollow shank portion, a head portion having a width larger than the width of the shank portion, and a bore extending the entire length of the shank portion, wherein the shank has a length of between about 4-12 mm and a width of between about 1-4 mm; the head has a width of between about 2-6 mm and a length of between about 0.7-3 mm; and the bore has a diameter of between about 0.8-1.3 mm. ### Claim 7 (depends on 6) The kit of claim 6, wherein the container further comprises an applicator which is reversibly attached to the vessel wall traversing device. ### Claim 8 (depends on 6) The kit of claim 6, wherein the vessel wall traversing device comprises a biocompatible plastic. ### Claim 9 (depends on 6) The kit of claim 6, wherein the vessel wall traversing device comprises an anti-microbial agent. ### Claim 10 (depends on 6) The kit of claim 6, wherein the vessel wall traversing device comprises an anti-thrombogenic agent. ### Claim 11 (depends on 6) The kit of claim 6, wherein the kit further comprises a micropuncture needle. ### Claim 13 (depends on 6) The kit of claim 6, wherein the kit further comprises a flexible cannula. ### Claim 14 (depends on 6) The kit of claim 6, wherein the kit further comprises a stiff dialator having an end sized to fit the head portion of the vessel wall traversing device. ### Claim 15 A kit comprising (i) a hermetically sealed container housing at least a first and a second sterile vessel wall traversing device each shaped like a blunt-ended nail and comprising a hollow shank portion, a head portion having a width larger than the width of the shank portion, and a bore extending the entire length of the shank portion, wherein the shank has a length of between about 4-12 mm and a width of between about 1-4 mm; the head has a width of between about 2-6 mm and a length of between about 0.7-3 mm; and the bore has a diameter of between about 0.8-1.3 mm; and (ii) at least a first and second flexible cannula. ### Claim 16 (depends on 15) The kit of claim 15, wherein the first flexible cannula has a different color than the second flexible cannula. ### Claim 17 (depends on 15) The kit of claim 15, wherein a portion of the first flexible cannula comprises a scar-promoting material. ### Claim 18 (depends on 17) The kit of claim 17, wherein the scar-promoting material comprises a polyethylene terephthalate cuff. ### Claim 19 (depends on 17) The kit of claim 17, wherein the scar-promoting material is between 0.2-2 cm in length along the longitudinal axis of the cannula, and extends between 0.05-0.3 cm from the outer surface of the cannula.
