An apparatus for sealing a puncture through a vessel wall including a positioning assembly, a sheath releasably engaged with the positioning assembly, and a support member axially advanceable through the sheath. The positioning assembly includes a positioning element positioned at a distal portion of the positioning assembly and a sealant disposed at a distal portion of the positioning assembly. The sheath guides the sealant and positioning assembly to the puncture in the vessel wall.

1. A method for sealing an arteriotomy comprising: inserting a sheath into the arteriotomy;inserting a cartridge assembly extending from a handle into the sheath until a proximal sheath hub engages a distal handle hub, the cartridge assembly comprising: an elongate member comprising a proximal end and a distal end,an expandable positioning element at the distal end of the elongate member, anda sealant adjacent the positioning element, and a support tube proximal of the sealant;expanding the positioning element;locking the positioning element in an expanded state;retracting the positioning element within a vessel having the arteriotomy until the positioning element abuts the arteriotomy;disengaging the sheath from the cartridge assembly, such that the sheath may be moved relative to the sealant;retracting the sheath to expose the sealant;tamping the sealant with the support tube;unlocking the positioning element to allow for the positioning element to be reduced in size;releasing a retraction lock that prevents the elongate member from moving proximally;retracting the positioning element from the sealant by withdrawing the elongate member proximally; andretracting the handle, cartridge assembly, and sheath from the arteriotomy leaving sealant to seal the arteriotomy. 2. The method of claim 1, wherein the locking is performed by actuating a first actuator on the handle. 3. The method of claim 1, wherein the disengaging is performed by actuating a second actuator on the handle. 4. The method of claim 1 wherein the retracting the sheath is performed by retracting the handle. 5. The method of claim 1, wherein the tamping is performed by actuating a third actuator on the handle. 6. The method of claim 1, wherein the retracting the positioning element from the sealant is performed by a fourth actuator on the handle. 7. The method of claim 1, wherein the locking is performed by actuating a first actuator on the handle, the disengaging is performed by actuating a second actuator on the handle, the tamping is performed by actuating a third actuator on the handle, and the retracting the positioning element from the sealant is performed by a fourth actuator on the handle, and wherein the first, second, third, and fourth actuators are positioned in the order recited along the handle. 8. The method of claim 1, wherein the steps are performed in the order recited. 9. A method for sealing an arteriotomy in a patient comprising: inserting a sheath into the arteriotomy;inserting a cartridge assembly extending from a handle into the sheath until the handle engages the sheath, the cartridge assembly comprising: an elongate member,a positioning element at a distal end of the elongate member, anda sealant adjacent the positioning element, and a support tube proximal of the sealant;retracting the positioning element within a vessel having the arteriotomy until the positioning element abuts the arteriotomy;disengaging the sheath from the cartridge assembly by actuating a first button, such that the sheath may be moved relative to the sealant;retracting the sheath to expose the sealant;tamping the sealant with the support tube by actuating a second button to advance the support tube distally, wherein the tamping is performed by displacing a spring member within the handle;retracting the positioning element from the sealant by actuating a third button; andretracting the handle, cartridge assembly, and sheath from the arteriotomy leaving sealant within the patient. 10. The method of claim 9, further comprising expanding the positioning element and locking the positioning element in an expanded state. 11. The method of claim 10, further comprising expanding the positioning element until an indicator indicates that the positioning element is fully expanded. 12. The method of claim 9, wherein retracting the positioning element from the sealant occurs after tamping the sealant. 13. The method of claim 9, wherein the handle is configured such that tamping the sealant can be performed using a single hand. 14. The method of claim 9, wherein disengaging the sheath, tamping the sealant, and retracting the positioning element are each performed by actuating a corresponding actuator, and wherein the actuators are positioned along the handle for actuation by a single hand. 15. The method of claim 9, wherein after retracting the sheath, the sheath reengages the cartridge assembly, such that the cartridge assembly and handle can be retracted together. 16. The method of claim 9, wherein disengaging the sheath from the cartridge assembly permits displacement of the spring member. 17. The method of claim 9, wherein tamping the sealant releases the elongate member from the support tube, such that the positioning element can move relative to the sealant. 18. The method of claim 9, further comprising a step of expanding the positioning element prior to retracting the positioning element within the vessel until the positioning element abuts the arteriotomy. 19. The method of claim 9, further comprising a step of deflating the positioning element prior to retracting the positioning element from the sealant. 20. The method of claim 9, wherein the step of actuating the third button releases a retraction lock that permits the elongate member to move proximally relative to the support tube to retract the positioning element from the sealant.
