A RICC assembly can include a RICC, an introducer, and a coupling system configured to couple the RICC and the introducer together. A catheter tube of the RICC includes a side aperture in a distal-end portion of the catheter tube, which opens into an introducing lumen extending to a distal end of the RICC. The introducer includes an introducer needle extending through the distal end of the RICC when the RICC assembly is in at least a ready-to-deploy state thereof. The introducer is configured to be actuated with a single finger of a hand while holding a distal-end portion of the introducer between a thumb and another finger or fingers of the hand. The coupling system includes a distal coupler slidably attached to the catheter tube proximal of the side aperture. ## Claims ### Claim 1 A syringe, comprising: a barrel having a syringe tip in a distal-end portion of the barrel; a plunger disposed in the barrel; and a syringe housing encircling the barrel, the syringe housing either integral with or coupled to a proximal-end portion of the plunger. ### Claim 2 (depends on 1) The syringe of claim 1, wherein the plunger is withdrawn from the barrel by proximally sliding the syringe housing relative to the barrel. ### Claim 3 (depends on 1) The syringe of claim 1, further comprising a push tab proximally extending over the barrel from the distal-end portion of the barrel to which the push tab is coupled. ### Claim 4 (depends on 3) The syringe of claim 3, the push tab is coupled to the distal-end portion of the barrel by an integrated connector around the syringe tip. ### Claim 5 (depends on 3) The syringe of claim 3, wherein the push tab is configured for pushing against with a single finger of a hand while holding a distal-end portion of the syringe housing between a thumb and another finger or fingers of the hand to proximally slide the syringe housing relative to the barrel and withdraw the plunger from the barrel. ### Claim 6 (depends on 1) The syringe of claim 1, wherein the syringe tip in the distal-end portion of the barrel is configured to couple to a needle hub of an introducer needle. ### Claim 7 (depends on 1) The syringe of claim 1, further comprising an access guidewire disposed in an access-guidewire lumen formed of at least a plunger lumen of the plunger. ### Claim 8 (depends on 7) The syringe of claim 7, wherein the access guidewire has a length sufficient for extension of the access guidewire through the syringe tip and into a blood-vessel lumen of a patient. ### Claim 9 (depends on 7) The syringe of claim 7, wherein the plunger includes a sealing mechanism in a distal-end portion of the plunger for sealing off the access-guidewire lumen distal of the sealing mechanism. ### Claim 10 (depends on 9) The syringe of claim 9, wherein the sealing mechanism is configured to maintain a vacuum for aspirating blood when the plunger is withdrawn from the barrel. ### Claim 11 (depends on 7) The syringe of claim 7, further comprising a slider distally extending over the barrel from the syringe housing configured for actuating the access guidewire. ### Claim 12 (depends on 11) The syringe of claim 11, wherein the slider includes an extension extending through a longitudinal slot in each of the barrel and the plunger into the access-guidewire lumen where the extension is coupled to the access guidewire. ### Claim 13 (depends on 11) The syringe of claim 11, wherein the access guidewire is actuated by sliding the slider over the barrel with a single finger of a hand while holding a distal-end portion of the syringe housing between a thumb and another finger or fingers of the hand. ### Claim 14 A method for establishing access to a blood-vessel lumen of a patient, comprising: obtaining an introducer including a syringe coupled to an introducer needle, the syringe including: a barrel having a syringe tip in a distal-end portion of the barrel; a plunger disposed in the barrel; and a syringe housing encircling the barrel, the syringe housing either integral with or coupled to a proximal-end portion of the plunger; and establishing a needle tract from an area of skin to the blood-vessel lumen of the patient with a needle shaft of an introducer needle. ### Claim 15 (depends on 14) The method of claim 14, further comprising aspirating blood with the syringe to confirm a needle tip of the introducer needle is disposed in the blood-vessel lumen of the patient, the aspirating by proximally sliding the syringe housing relative to the barrel to withdraw the plunger from the barrel. ### Claim 16 (depends on 15) The method of claim 15, further comprising pushing against a push tab proximally extending over the barrel from the distal-end portion of the barrel to which the push tab is coupled with a single finger of a hand while holding a distal-end portion of the syringe housing between a thumb and another finger or fingers of the hand to proximally slide the syringe housing relative to the barrel and withdraw the plunger from the barrel. ### Claim 17 (depends on 14) The method of claim 14, further comprising advancing an access guidewire disposed in an access-guidewire lumen formed of at least a plunger lumen of the syringe and a needle lumen of the introducer needle into the blood-vessel lumen of the patient beyond a needle tip of the introducer needle. ### Claim 18 (depends on 17) The method of claim 17, further comprising sliding a slider distally extending over the barrel from the syringe housing with a single finger of a hand while holding a distal-end portion of the syringe housing between a thumb and another finger or fingers of the hand to advance the access guidewire. ### Claim 19 (depends on 18) The method of claim 18, wherein the slider includes an extension extending through a longitudinal slot in each of the barrel and the plunger into the access-guidewire lumen where the extension is coupled to the access guidewire. ### Claim 20 (depends on 17) The method of claim 17, wherein the plunger includes a sealing mechanism in a distal-end portion of the plunger for sealing off the access-guidewire lumen distal of the sealing mechanism, the sealing mechanism configured to maintain a vacuum for aspirating blood when the plunger is withdrawn from the barrel.
