Claim 18:
19. A device for sealing an aperture in a tissue, the device comprising:
a. an implant configured to seal the aperture when positioned adjacent to the aperture, the implant comprising:
(i) a foot including a distal portion configured to be disposed distally beyond a distal surface of the tissue when the device is in a sealing position, and a proximal portion having a longitudinal axis and configured to extend proximally through the aperture and proximally beyond a proximal surface of the tissue when the device is in the sealing position; and
(ii) a thin flexible wing having at least one surface and a longitudinal plane; and
b. a delivery shaft configured to engage the implant to allow the implant to be maneuvered into sealing engagement with a distal surface of the tissue, the delivery shaft comprising:
(i) a handle coupled to the delivery shaft;
(ii) an actuator moveable between a first position and second position relative to the handle; and
(iii) a depressable lock member, moveable between a first position and a second, depressed position, such that in the first position, the lock member engages the actuator in the actuator's first position, and in a second position, the lock member disengages the actuator,
wherein a guidewire extends through the handle, wherein the implant comprises a guide channel configured to receive the guidewire,
wherein the lock member comprises a mechanism to prevent inadvertent depression prior to removal of the guidewire,
wherein the mechanism comprises a projection on the lock member and a recess on the handle,
wherein the mechanism is locked when the projection is received in the recess and the mechanism is unlocked when the projection is out of engagement with the recess,
wherein the mechanism must be unlocked in order to depress the lock member, and
wherein a user must apply a proximally directed force to the lock member to unlock the mechanism.
