Vascular hole closure device
First Claim
1. A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall, the device comprising:
- a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture;
first and second retainers positionable external of the vessel and being movable independently, the first and second retainers being one of substantially cylindrical and substantially pill shaped;
a first flexible connecting member operatively connecting the first retainer to the covering member, the first flexible connecting member movable proximally to advance the first retainer toward the covering member and;
a second flexible connecting member operatively connecting the second retainer to the covering member, the second flexible connecting member movable proximally to advance the second retainer toward the covering member.

Abstract
A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall. The device includes a covering member positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture. First and second retainers are positionable external of the vessel and have a tip of a smaller transverse dimension and facing in a direction toward the covering member for advancement toward the covering member. A flexible connecting member operatively connects the covering member and the first retainer and moves the first retainer toward the covering member.

9. A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall, the device comprising:
-
a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture; first and second retainers positionable external of the vessel and proximal of the covering member, the first and second retainers each having a body of a first transverse dimension and having a substantially cylindrical configuration with a longitudinal axis transverse to the longitudinal axis of the covering member in a placement position; and a first flexible connecting member operatively connecting the covering member and the first retainer and a second flexible connecting member operatively connecting the covering member and the second retainer, the first flexible connecting member movable to move the first retainer toward the covering member and the second flexible connecting member movable to move the second retainer toward the covering member, the first and second flexible connecting members being independently movable. - View Dependent Claims (10, 11, 12)

13. A device for closing an aperture in a vessel wall, the aperture having an external opening in an external region of the vessel wall and an internal opening in an internal region of the vessel wall, the device comprising:
-
a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture, the covering member having a dimension to prevent egress of fluid through the aperture, the covering member having a first opening and a second opening; first and second retainers positionable external of the vessel and proximal of the covering member in a placement position, the first and second retainers each having a body having a substantially cylindrical configuration, the first and second retainers being independently movable toward the covering member; and a first flexible connecting member operatively connecting the covering member and the first retainer, the first flexible connecting member being fixedly secured to the first retainer at one end wherein the first flexible connecting member is movable to move the first retainer toward the covering member as a second end of the first flexible connecting member is moved proximally, the first retainer remaining fixedly secured to the first flexible connecting member at the first end to maintain its position on the first flexible connecting member as it is moved toward the covering member, the second opening in the covering member configured to enable unrestricted movement of the first flexible connecting member through the second opening and the first opening in the covering member configured to restrict movement of the first flexible connecting member until a predetermined force is applied. - View Dependent Claims (14, 15, 16, 17, 18)
