Tissue puncture closure device

摘要

The present disclosure relates generally to methods and devices for closing and/or sealing an opening in a vessel wall and/or an adjacent tissue tract. In one illustrative embodiment, a device is provided for delivering and deploying an anchor, plug, suture, and/or locking element adjacent to the opening in the vessel wall and/or tissue tract.

主权项

1. A method of deploying a vascular sealing plug in a patient, comprising:
obtaining a vascular closure system, the vascular closure system comprising:
an insertion sheath having a lumen therethrough;a device sheath adapted to be inserted into the lumen of the insertion sheath, the device sheath fixedly coupled to a handle extending therefrom, the handle adapted to be coupled to the insertion sheath;wherein the handle includes a stored energy source, a control system, and a motor each disposed therein; anda sealing assembly including an anchor disposed at a distal end of the device sheath and a suture operatively connecting the anchor to a vascular plug disposed within the distal end of the device sheath; inserting a distal end of the insertion sheath into a puncture through a wall of a blood vessel into a lumen of the blood vessel; inserting the device sheath into the insertion sheath with the anchor generally oriented axially to align with the device sheath; advancing the device sheath distally through the lumen of the insertion sheath until the anchor extends past the distal end of the insertion sheath; coupling the handle to the insertion sheath; after coupling the handle to the insertion sheath, actuating a seating mechanism to translate the anchor against the distal end of the insertion sheath and orient the anchor generally transverse to the insertion sheath; wherein coupling the handle to the insertion sheath activates a position trigger within the handle, wherein activating the position trigger automatically actuates the seating mechanism; withdrawing the insertion sheath and the handle proximally until the anchor is seated against an interior surface of the wall of the blood vessel; retracting the insertion sheath from the wall of the blood vessel while maintaining the device sheath and the handle in position for deployment of the vascular plug; actuating the motor, wherein the motor drives a push rod distally to deploy and axially compress the vascular plug at a controlled rate within the distal end of the device sheath; releasing the suture from the handle; withdrawing the handle, the device sheath, and the insertion sheath from the patient after releasing the suture.
