Abstract
An aortic closure device for trans-caval procedures having a deployment assembly having a housing, a release tube, and a delivery tube disposed within the release tube, a tamper disposed within the delivery tube, a sealing element, a suture assembly, and an actuator.
Claims20
An aortic closure device, comprising:
- a deployment assembly configured to be inserted in a puncture in an aorta;
- a tamper carried by the deployment assembly, the tamper having a tamper channel that extends therethrough;
- a sealing element captured by the deployment assembly;
- a suture assembly that extends through the tamper channel such that tamper is movable along the suture assembly, the suture assembly being releasably coupled to the sealing element;
- and
- an actuator coupled to the release tube, the delivery tube, and the tamper tube, the actuator having a) a first actuation phase that causes the deployment assembly to release the sealing element therefrom while remaining coupled to the suture assembly, b) a second actuation phase that causes the tamper to move in the distal direction toward contact with the sealing element, and c) a third actuation phase that causes the tamper to move in a proximal direction that is opposite the distal direction to release the suture assembly from the sealing element.

A tamper, comprising:
- a tamper body that is elongate along a longitudinal direction, the tamper body defining a distal end, a proximal end opposite the distal end, and an outer surface;
- a tamper channel that extends from the proximal end to the distal end along the longitudinal direction, the tamper channel configured to receive a suture assembly therethrough,
- at least one first cut at the distal end and that extends from the outer surface toward the tamper channel;
- and
- at least one second cut at the distal end opposite the first cut and that extends from the outer surface toward the tamper channel, wherein the at least one first cut and the least one second cut are configured to permit the distal end of the tamper to flex.

A method for sealing a puncture of an artery, the method comprising the steps of:
- advancing a tamper that extends through at least a portion of a sealing element along a guidewire in a distal direction toward the puncture, the sealing element being coupled to a suture assembly, and, wherein a deployment assembly supports the tamper and releasably holds the sealing element;
- inserting the deployment assembly through the puncture of the artery;
- during a first phase, actuating an actuator of the deployment assembly in a first direction until the deployment assembly releases the sealing element therefrom while remaining coupled to the suture assembly;
- during a second phase, actuating the actuator in a second direction until the tamper moves in the distal direction toward contact with the sealing element;
- and
- during a third phase, actuating the actuator in the first direction until the tamper moves in a proximal direction that is opposite the distal direction and releases the suture assembly from the sealing element.
