VASCULAR CLOSURE DEVICE
First Claim
Patent Images
1. A vascular closure device for closing a passage through tissue proximate to a blood vessel, the vascular closure device comprising:
- an elongated housing having a proximal end and a distal end, the distal end adapted to be proximate the tissue;
a first and a second engagement member releasably arranged with the elongated housing;
a deployment member arranged with the elongated housing and adapted to deploy the first and the second engagement member at a distance from each other in engaged contact with said tissue, without engaging a wall portion of the blood vessel; and
a retraction member arranged with the elongated housing and adapted to reduce the distance between the first and the second engagement member to close said passage.

29. A method of closing a passage through tissue 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 and a second engagement member releasably arranged with the elongated housing; a deployment member arranged with the elongated housing; and a retraction member arranged with the elongated housing positioning the distal end of the vascular closure device proximate to the tissue, deploying, using the deployment member, the first and the second engagement member from the vascular closure device to engage with said tissue at a distance from each other, without engaging a wall portion of the blood vessel, and applying a predetermined retraction force, using the retraction member, to reduce the distance between the first and the second engagement member to close said passage. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

41. A vascular closure device for treating a passage in a blood vessel by closing a passage through tissue proximate to a blood vessel, the vascular closure device comprising:
-
an elongated housing having a proximal end, a distal end, and a distal section; a plurality of engagement members which are each adapted to be secured to tissue upon deployment into tissue; a plurality of deployment members adapted to extend from the distal section of the elongated housing in a distal and radially outward direction, each of the deployment members being adapted to deploy at least one of the engagement members into the tissue proximate to the blood vessel such that the engagement members are secured to the tissue proximate to the blood vessel and disposed at a distance from each other in engaged contact with said tissue, without engaging a wall portion of the blood vessel; a plurality of elongate flexible tension elements, each tension element being secured to at least one engagement member; and a retraction member coupled in operative arrangement with the tension elements and adapted to apply axial tension to the tension elements and reduce the distance between the engagement members to a radially retracted state to close the passage in the tissue proximate to the blood vessel. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)
