Closure device and method for sealing a puncture in a blood vessel

A closure device for sealing a percutaneous puncture in the wall of a blood vessel, comprising:

• an inner member,
• an outer member,
• an insertion tool having a housing and an actuator which is operable in a first mode in which the actuator is configured to cause deployment of the inner member inside the vessel and operable in a second mode in which the actuator is configured to cause tamping of the outer member on an outside of the vessel,
• wherein the actuator is arranged to be set into said second mode in response to a pulling force acting on a filament connecting the inner member and the outer member,
• wherein the actuator is configured to be both contacted and operated by a user in both the first and second modes,
• wherein in the second mode, movement of the actuator relative to the housing causes said tamping of the outer member,
• a seal assembly;
• wherein the housing is arranged to be positioned by a distal end of the housing for guidance of the seal assembly,
• the seal assembly comprising said inner member, attached to a distal end of said filament and said outer member, movably carried on the filament and spaced from the inner member;
• wherein the closure device further comprises:
• a pusher, guided in the housing, a distal end of the pusher detachably connected to the inner member;
• a tamping member, guided in the housing, the filament running through the tamping member and carrying the outer member and the inner member outside a distal end of the tamping member, and
• an actuator mechanism controlling the actuator in said first mode to drive the pusher for deployment of the inner member, whereupon the actuator mechanism is adapted to disable the actuator until a pulling force acting on the filament causes the actuator to be set into said second mode to drive the tamping member for tamping the outer member;
• a sleeve;
• a slider;
• wherein the sleeve is telescopically received in the housing, the actuator is telescopically received in the sleeve, the seal assembly is operatively connected to the slider, and the slider is engaged by the actuator in a first relative position to be moved by the actuator for deployment of the inner member, and displaceable relative to the actuator into a second relative position wherein the slider is engaged by the actuator to be moved thereby for tamping the outer member;
• wherein the slider is displaced from the first relative position to the second relative position in response to a pulling force being applied to the closure device and acting through the filament which is arrested by its distal end being attached to the inner member and by its proximal end being connected to the slider;
• wherein the actuator is temporarily arrested in the sleeve and disabled in the second mode of operation, to be released by action of the slider as the slider is displaced from said first to said second relative position;
• a cam formed on a distal end of the slider and arranged to disengage a snap lock connection between the actuator and the sleeve;
• and a compressible spring, acting between the sleeve and the actuator, effective for ejecting the actuator into said second mode.

• wherein the actuator is temporarily arrested in the sleeve and disabled in the second mode of operation, to be released by action of the slider as the slider is displaced from said first to said second relative position;
• wherein the proximal end of the filament is connected to the slider by a sliding connection having a bar, and captured by a beam formed on the sleeve so as to be released from the slider through relative movement of the beam as the slider moves with the actuator in said second mode.

• wherein the housing supports the actuator in both the first and second modes,
• wherein the insertion tool comprises a mechanism configured such that, when the actuator is set in said second mode, a separate operation of the actuator causes movement of the outer member along the filament and towards the inner member and causes tamping of the outer member,
• wherein the actuator portion is configured to be directly contacted by a user in both the first and second modes.
