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 distal covering member positionable inside the vessel against the internal opening of the aperture, the covering member having a first opening, a second opening, a third opening and a fourth opening;
a proximal first retainer positionable external of the vessel;
a proximal second retainer positionable external of the vessel; and
a first flexible connecting member operatively connecting the first retainer to the covering member and a second flexible connecting member operatively connecting the second retainer to the covering member, the first flexible connecting member advancing the first retainer toward the covering member, the first opening of the covering member restricting movement of the first flexible connecting member and the second opening of the covering member providing for freer movement of the first flexible connecting member, the second flexible connecting member advancing the second retainer toward the covering member, the third opening of the covering member restricting movement of the second flexible connecting member and the fourth opening of the covering member providing for freer movement of the second flexible connecting member.

Abstract
A device for closing an aperture in a vessel wall comprising a covering member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture and having a dimension to prevent egress of fluid through the aperture and having a first opening. A first retainer is positionable external of the vessel. A flexible connecting member operatively connects the covering member and the first retainer, wherein the first opening of the covering member is configured to restrict movement of the connecting member.

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 distal covering member positionable inside the vessel against the internal opening of the aperture, the covering member having an upper surface, a lower surface and a first opening extending through the upper surface and lower surface; a proximal first retainer positionable external of the vessel; and a first flexible connecting member operatively connecting the first retainer and the covering member, the first flexible connecting member having a first portion, a second portion and an intermediate portion between the first and second portions, a first portion of the first flexible connecting member secured to the first retainer by securement within the first retainer and terminating at the first retainer, the first opening of the covering member restricting movement of the first flexible connecting member, wherein the first opening retains the flexible connecting member in a fixed position along a length and a sufficient proximal force on the second portion moves the first flexible connecting member within the first opening and advances the first retainer toward the distal covering member, wherein when the sufficient proximal force is terminated, the flexible connecting member is restricted from movement by the first opening. - View Dependent Claims (14, 15, 16, 17, 18)

19. 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 distal covering member positionable inside the vessel against the internal opening of the aperture, the covering member having a first opening; a proximal first retainer positionable external of the vessel; and a first flexible connecting member operatively connecting the first retainer and the covering member, the first flexible connecting member having a first portion, a second portion and an intermediate portion between the first and second portions, the first retainer secured to a first portion of the first flexible connecting member, the first opening of the covering member restricting movement of the first flexible connecting member, wherein the first opening retains the flexible connecting member in a fixed position along a length and a sufficient proximal force on the second portion moves the first flexible connecting member within the first opening and advances the first retainer toward the distal covering member, wherein when the sufficient proximal force is terminated, the flexible connecting member is restricted from movement by the first opening and further including a second retainer positionable external of the vessel, wherein the first retainer is advanceable from a first position within a delivery device to a second position outside a distal opening of the delivery device and the second retainer is advanceable from a first position within the delivery device to a second position outside the distal opening of the delivery device subsequent to advancement of the first retainer outside the distal opening of the delivery device. - View Dependent Claims (20)
