Abstract
A tissue closure device includes a collapsible plug and an actuator. The plug has a surface extending between a proximal face and an opposing distal face. A lumen extends through the plug between the proximal and distal faces along a longitudinal axis. The plug is collapsible between a non-collapsed state in which the lumen is open and a collapsed state in which the lumen is closed. The actuator is configured to move the plug between the non-collapsed state and the collapsed state by being pulled proximally, such as through the lumen.
Claims19
A closure device for closing an opening in tissue having an interior surface, the closure device comprising:
- a collapsible plug having an outer surface extending between a proximal face and an opposing distal face, a lumen extending through the plug between the proximal and distal faces along a longitudinal axis, the plug being collapsible between a non-collapsed state in which the lumen is open and a collapsed state in which the lumen is closed, the plug being configured to close the opening in the tissue in the collapsed state;
- and
- an actuator configured to move the plug between the non-collapsed state and the collapsed state by being pulled through the lumen from a distal end of the lumen formed at the distal face of the plug to the proximal face of the plug.
A closure device for closing an opening in tissue having an interior surface and an exterior surface, the closure device comprising:
- a collapsible plug having a surface extending between a proximal face configured to engage the interior surface of the tissue and an opposing distal face, a lumen extending through the plug between the proximal and distal faces along a longitudinal axis, a plurality of tissue engaging members projecting from the proximal face and configured to engage the interior surface of the tissue, the plug being collapsible between a non-collapsed state in which the lumen is open and a collapsed state in which the lumen is closed, the plug being configured to close the opening in the tissue when the plug is collapsed and a portion of the proximal face of the plug enters the opening in tissue;
- and
- an actuator having a shaft extending between a proximal end and a distal end, an engaging element being positioned at the distal end of the shaft, the shaft slidably engaging with and extending through the lumen of the plug, and the engaging element engaging with the distal face of the plug, the actuator being configured to move the plug between the non-collapsed state and the collapsed state by being pulled through the lumen from a distal end of the lumen formed at the distal face of the plug to the proximal face of the plug.
