Patent Images
1. A method of closing a passage through tissue which is proximate to a blood vessel, the method comprising:
- providing a vascular closure device, the vascular closure device comprising;
an elongated housing having a proximal end and a distal end,a first engagement member and a second engagement member releasably arranged with the elongated housing,a first deployment member and a second deployment member arranged with the elongated housing, anda first tension element secured to the first engagement member and a separate second tension element secured to the second engagement member;
positioning the distal end of the elongated housing proximate to the tissue which is proximate to the blood vessel;
deploying the first engagement member with the first deployment member and deploying the second engagement member with the second deployment member in a distal and radially outward direction from the elongated housing of the vascular closure device and engaging the first engagement member and second engagement member with the tissue which is proximate to the blood vessel at a distance from each other and without engaging the blood vessel; and
applying a retraction force to the first engagement member with the first tension element and to the second engagement member with the second tension element to reduce the distance between the first engagement member and the second engagement member to close the passage in the tissue which is proximate to the blood vessel.
