Patent Images
1. A vascular closure device, comprising:
- a housing having an elongate configuration with an axial length greater than a transverse dimension thereof, a proximal end, a distal end and a distal section;
a plurality of anchor deployers which are slidably disposed within the housing adjacent each other at the distal section of the housing and which are configured to extend and spread from the distal section of the housing, each anchor deployer comprising;
an deployment rod which is slidably disposed relative to the housing and which includes an elongate resilient configuration and a distal end that extends distally and radially from the distal section of the housing, andan anchor which is secured to the distal end of the deployment rod and which is configured to grip tissue; and
a tissue grip which is deployable from the distal end of the housing.

24. A method for vascular closure, comprising:
-
disposing a distal end of a housing of a vascular closure device to a position adjacent a passage in a tissue layer; deploying a plurality of anchor deployers from a distal section of the housing by distally advancing deployment rods of the anchor deployers in a distal and radially outward direction from the housing into the tissue layer in positions disposed about the passage in the tissue layer; securing respective anchors of the anchor deployers to the tissue layer in positions disposed about the passage in the tissue layer; proximally retracting the deployment rods back into the distal section of the housing so as to draw the anchors and respective tissue layer portions secured thereto together adjacent the distal section of the housing; deploying a tissue grip over the anchors and onto the tissue layer portions secured to the anchors so as to secure the tissue layer portions together; and releasing the anchors from the tissue layer portions. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method for vascular closure, comprising:
-
disposing a distal end of a housing of a vascular closure device to a position adjacent a passage in a tissue layer; deploying a plurality of anchor deployers from a distal section of the housing by distally advancing deployment rods of the anchor deployers in a distal and radially outward direction from the housing into the tissue layer in positions disposed about the passage in the tissue layer; securing respective anchors of the anchor deployers to the tissue layer in positions disposed about the passage in the tissue layer; proximally retracting the deployment rods back into the distal section of the housing so as to draw the anchors and respective tissue layer portions secured thereto together adjacent the distal section of the housing; deploying a tissue grip over the anchors and onto the tissue layer portions secured to the anchors so as to secure the tissue layer portions together; and detaching each anchor from the respective deployment rod secured thereto. - View Dependent Claims (35)

36. A method for vascular closure, comprising:
-
disposing a vascular closure device adjacent a passage in a tissue layer which is disposed above and adjacent an access hole in a blood vessel of a patient; deploying a plurality of anchors from a distal section of the vascular closure device in a distal and radially outward direction therefrom and engaging the tissue layer in positions disposed about the passage in the tissue layer with the anchors; securing the anchors to the tissue layer in the positions disposed about the passage in the tissue layer; proximally retracting the anchors closer together so as to draw the anchors and respective tissue layer portions secured thereto together thereby closing the passage in the tissue layer; and deploying a tissue grip onto the tissue layer portions drawn together by the anchors so as to secure the drawn together tissue layer portions thereby closing the passage in the tissue layer and achieving vascular closure of the access hole in the blood vessel. - View Dependent Claims (37, 38)
