The device includes an automatic mechanism, a shaft fixedly connected to the automatic mechanism, a seal assembly attached to the distal end of the shaft, and a pushing rod also engaging the seal assembly, the automatic mechanism moving the pushing rod from a first position to a second position in response to the shaft being pulled distally a predetermined distance. ## Claims ### Claim 1 A device for sealing an opening in the wall of a blood vessel, the blood vessel having an interior wall surface, an exterior wall surface, and a lumen, the device comprising: a pushing rod, the pushing rod having an opening therealong; a shaft disposed within at least a portion of the opening of the pushing rod; a shaft retaining element fixedly attached to the shaft; a pusher, the pusher fixedly attached to the pushing rod; a spring; a spring retainer, the spring biased against at least one surface of the spring retainer; and at least one retention element rotatably movable between a first and a second position, the at least one retention element engages the spring retainer and the shaft retaining element in the first position; and a seal assembly having a first portion and a second portion, the seal assembly operatively attached at the first portion to the distal end of the shaft, the seal assembly configured to engage the interior wall surface and the exterior wall surface of the blood vessel, wherein the pushing rod operatively engages the seal assembly at the second portion and is movable relative to the shaft, the pushing rod moving from a first position to a second position in response to the shaft moving distally causing the first portion and the second portion of the seal assembly to move relative to one another. ### Claim 2 (depends on 1) The device for sealing an opening according to claim 1, wherein the at least one retention element comprises two retention elements. ### Claim 3 (depends on 1) The device for sealing an opening according to claim 1, wherein the at least one retention element has two legs, a first leg engaging the spring retainer and a second leg engaging the shaft retaining element. ### Claim 4 (depends on 3) The device for sealing an opening according to claim 3, wherein the second leg is longer than the first leg. ### Claim 5 (depends on 1) The device for sealing an opening according to claim 1, further comprising a safety latch, the safety latch movable between a first position and a second position, the safety latch engaging a slot in the pusher thereby preventing the pusher from moving the pushing rod. ### Claim 6 A device for sealing an opening in the wall of a blood vessel, the blood vessel having an interior wall surface, an exterior wall surface, and a lumen, the device comprising: a pushing rod, the pushing rod having an opening therealong; a shaft disposed within at least a portion of the opening of the pushing rod; a shaft retaining element fixedly attached to the shaft; a pusher, the pusher fixedly attached to the pushing rod; a spring; a spring retainer, the spring biased against at least one surface of the spring retainer; and at least one retention element rotatably movable between a first and a second position, the at least one retention element engages the spring retainer and the shaft retaining element in the first position; and a seal assembly having a first portion and a second portion, the seal assembly operatively attached at the first portion to the distal end of the shaft, the seal assembly configured to engage the interior wall surface and the exterior wall surface of the blood vessel, wherein the pushing rod operatively engages the seal assembly at the second portion and is movable relative to the shaft, the at least one retention element rotating from the first position to the second position in response to the shaft moving distally. ### Claim 7 (depends on 6) The device for sealing an opening according to claim 6, wherein the at least one retention element comprises two retention elements. ### Claim 8 (depends on 6) The device for sealing an opening according to claim 6, wherein the at least one retention element has two legs, a first leg engaging the spring retainer and a second leg engaging the shaft retaining element. ### Claim 9 (depends on 8) The device for sealing an opening according to claim 8, wherein the second leg is longer than the first leg. ### Claim 10 (depends on 8) The device for sealing an opening according to claim 8, wherein each of the first and second legs have a flat surface at one end thereof. ### Claim 11 (depends on 6) The device for sealing an opening according to claim 6, further comprising a safety latch, the safety latch movable between a first position and a second position, the safety latch engaging a slot in the pusher thereby preventing the pusher from moving the pushing rod. ### Claim 12 (depends on 6) The device for sealing an opening according to claim 6, Wherein the at least one retention element engages a surface of the spring retainer and also engages a surface of the shaft retaining element in the first position.
