A handle for deploying a sealing device, the handle comprising: a housing having a slot with a length; a sealing device having an expandable wire frame comprising a distal bumper, distal eyelet, a locking loop (111, 206), a proximal eyelet and an optional center eyelet; a first tube having an opening at a distal end for the locking loop (111, 206) through which the locking loop (111, 206) protrudes to retain the sealing device on the first tube during deployment; a second tube housed within the first tube and threaded through the eyelets (202, 203, 204) of the sealing device; and a first linear actuator located within the slot, said first linear actuator operable to advance the first tube, the second tube, and the sealing device by advancing the first linear actuator along the length of the slot, and operable to retract the first tube, the second tube, and the sealing device by retracting the first linear actuator along the length of the slot, and wherein: - the first linear actuator is operable to move in the slot to prevent the second tube from moving either proximally or distally, such that proximal movement of the first linear actuator translates the first tube and proximal end of the sealing device proximally, thus elongating the sealing device; and - the first linear actuator is operable to move in the slot, such that distal movement of the linear actuator causes the first tube and proximal eyelet of sealing device to move distally to deploy the device. a housing having a slot with a length; a sealing device having an expandable wire frame comprising a distal bumper, distal eyelet, a locking loop (111, 206), a proximal eyelet and an optional center eyelet; a first tube having an opening at a distal end for the locking loop (111, 206) through which the locking loop (111, 206) protrudes to retain the sealing device on the first tube during deployment; a second tube housed within the first tube and threaded through the eyelets (202, 203, 204) of the sealing device; and a first linear actuator located within the slot, said first linear actuator operable to advance the first tube, the second tube, and the sealing device by advancing the first linear actuator along the length of the slot, and operable to retract the first tube, the second tube, and the sealing device by retracting the first linear actuator along the length of the slot, and wherein: - the first linear actuator is operable to move in the slot to prevent the second tube from moving either proximally or distally, such that proximal movement of the first linear actuator translates the first tube and proximal end of the sealing device proximally, thus elongating the sealing device; and - the first linear actuator is operable to move in the slot, such that distal movement of the linear actuator causes the first tube and proximal eyelet of sealing device to move distally to deploy the device. - the first linear actuator is operable to move in the slot to prevent the second tube from moving either proximally or distally, such that proximal movement of the first linear actuator translates the first tube and proximal end of the sealing device proximally, thus elongating the sealing device; and - the first linear actuator is operable to move in the slot, such that distal movement of the linear actuator causes the first tube and proximal eyelet of sealing device to move distally to deploy the device.
