An apparatus for delivering a clip includes an introducer sheath including an outer surface extending between its proximal and distal ends. A clip is carried on the outer surface, e.g., on a carrier assembly that is slidable along the outer surface from the proximal end towards the distal end. A skin overlies the outer surface of the sheath and the carrier assembly that is separable from the outer surface as the carrier assembly is advanced from the proximal end towards the distal end of the sheath. During use, the distal end of the sheath is inserted into an opening through tissue, e.g., into a puncture communicating with a blood vessel. The carrier assembly is advanced towards the distal end of the sheath, causing the skin to separate from the outer surface of the elongate member, and the clip is deployed from the carrier to seal the opening.
1. A method for closing an opening in a blood vessel, comprising: introducing a vessel closure system toward the opening in the blood vessel;locating the opening in the blood vessel;advancing an obturator from the vessel closure system and into the blood vessel, the obturator comprising a biodegrada
1. A method for closing an opening in a blood vessel, comprising: introducing a vessel closure system toward the opening in the blood vessel;locating the opening in the blood vessel;advancing an obturator from the vessel closure system and into the blood vessel, the obturator comprising a biodegradable distal tip distal a positioning element;orientating the obturator transverse to a longitudinal axis of the vessel closure system in a deployed state by actuating a shaft attached to the obturator;engaging an inner surface of the blood vessel with an upper surface of positioning element of the obturator to locate the blood vessel; andmanipulating an actuator to deploy a closure element from the vessel closure system to close the opening in the blood vessel, a portion of the obturator remaining in the blood vessel and extending into a passage extending proximally from the opening. 2. The method as recited in claim 1, wherein advancing the obturator comprises advancing a portion of the obturator to advance from a distal end of the vessel closure system. 3. The method as recited in claim 1, wherein advancing the obturator comprises deploying a spline of the obturator transverse to a longitudinal axis of the shaft of a portion of the vessel closure system. 4. The method as recited in claim 1, wherein engaging the inner surface of the blood vessel comprises distally moving the obturator against the inner surface of the blood vessel. 5. The method as recited in claim 1, further comprising manipulating a trigger to release the obturator. 6. The method as recited in claim 1, wherein manipulating the actuator to deploy the closure element comprises distally advancing another shaft extending from a proximal end toward a distal end of the vessel closure system. 7. The method as recited in claim 6, further comprising manipulating the actuator to deploy the closure element to engage tissue surrounding the opening in the blood vessel. 8. A method for closing an opening in a blood vessel, comprising: locating the opening in the blood vessel using a bleedback indicator;advancing a bioabsorbable obturator from a vessel closure system and into the blood vessel;orientating the obturator transverse to a longitudinal axis of the vessel closure system in a deployed state by actuating a shaft attached to the obturator;engaging an inner surface of the blood vessel with an upper surface of the obturator;depressing a plunger to deploy a closure element from the vessel closure system to penetrate a portion of tissue of the blood vessel surrounding the opening to close the opening in the blood vessel and leave a portion of the obturator remaining in the blood vessel; andwithdrawing the obturator through the opening and into a portion of a passage extending from a patient's skin toward the opening proximal the closure element and detaching a bioabsorbable distal tip of the obturator into the portion of the passage to enhance sealing of the opening. 9. The method as recited in claim 8, wherein locating the opening comprises advancing a portion of the vessel closure system into the blood vessel until blood exits the bleedback indicator. 10. The method as recited in claim 8, further comprising advancing a portion of an outer member of the vessel closure system into contact with a patient's skin. 11. The method as recited in claim 10, wherein advancing the portion of the outer member occurs prior to deploying the closure element from a distal end of the vessel closure system. 12. The method as recited in claim 8, further comprising distally advancing an outer member about the shaft, with a portion of the shaft extending proximally from the outer member. 13. The method as recited in claim 8, wherein depressing the plunger to deploy the closure element further comprises depressing the plunger to move one or more telescoping members. 14. The method as recited in claim 13, wherein the one or more telescoping members extend distally from a handle of the vessel closure system during deployment of the closure element. 15. A method for closing an opening in a blood vessel, comprising: introducing a vessel closure system over a guidewire toward the opening in the blood vessel;locating the opening in the blood vessel using a bleedback indicator;advancing a bioabsorbable obturator from the vessel closure system and into the blood vessel;orienting the obturator transverse to a longitudinal axis of the vessel closure system in a deployed state by actuating a shaft attached to the obturator;engaging an inner surface of the blood vessel with an upper surface of the obturator;depressing a plunger to deploy an annular closure element from the vessel closure system to close the opening in the blood vessel, the closure element being disposed in a portion of a wall of the blood vessel surrounding the opening, the closure element being fabricated from bioabsorbable materials; andwithdrawing a distal tip of the obturator from within the blood vessel and proximally through the opening and detaching the bioabsorbable distal tip of the obturator in a portion of a passage extending to a patient's skin to enhance sealing of the opening. 16. The method as recited in claim 15, wherein the blood vessel is the femoral artery. 17. The method as recited in claim 15, wherein the vessel closure system further comprises a sleeve extending towards a distal end of the shaft. 18. The method as recited in claim 15, wherein an opening through tissue communicates with the blood vessel, and wherein the deploying step comprises substantially sealing the opening from blood flow therethrough with the closure element. 19. The method as recited in claim 15, wherein the orienting step further comprises withdrawing the obturator towards a wall of the blood vessel. 20. The method as recited in claim 15, further comprising manipulating a trigger to release the obturator. 21. The method as recited in claim 15, wherein advancing the bioabsorbable obturator comprises advancing a portion of the obturator to advance from a distal end of the vessel closure system.
