Abstract
A device for closing an aperture in a vessel wall comprising an elongated member positionable inside the vessel against an internal opening of the aperture and having a dimension exceeding a dimension of the internal opening of the aperture to prevent egress of fluid through the aperture. At least two curved legs are coupled to the elongated member, curve in a direction substantially perpendicular to the longitudinal axis of the elongated member, and are positionable outside the vessel to help retain the elongated member in position the legs.
Claims21
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:
- an elongated member formed from a first material and having a longitudinal axis extending through a vessel engaging surface, the elongated member positionable inside the vessel against the internal opening of the aperture, the vessel engaging surface configured with a dimension at least substantially equal to a dimension of the internal opening of the aperture to prevent egress of fluid through the aperture and configured to extend along the length of the vessel wall;
- and
- at least two curved legs formed from a second material different than the first material, the legs formed from a single element of metallic material and positionable outside the vessel to help retain the elongated member in position, the legs extending from the vessel engaging surface during insertion and placement of the elongated member and curved in different directions in the placement position,
- wherein the elongated member has a configuration and is movable between first and second positions with respect to the curved legs such that it is pivotable from a first insertion position to a second placement position at an angle to the first position, the elongated member maintaining the configuration in the first and second positions.
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 non-penetrating elongated patch member with non-sharpened edges having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture, the elongated member having a vessel engaging surface extending in a direction along the longitudinal axis and having a dimension at least substantially equal to a dimension of the internal opening of the aperture to prevent egress of fluid through the aperture by covering the aperture;
- and
- at least two curved legs formed from a single element of metallic material and positionable outside the vessel to help retain the elongated member in position, the legs being uncovered and curved in different directions and having free fully exposed ends curving inwardly toward each other.
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:
- an elongated member having a longitudinal axis and positionable inside the vessel against the internal opening of the aperture, the elongated member having a vessel engaging surface with a dimension at least substantially equal to a dimension of the internal opening of the aperture to prevent egress of fluid through the aperture, the elongated member being movable between a first insertion orientation and a second placement orientation to enable the vessel engaging surface to prevent egress of fluid;
- and
- at least two curved legs positionable outside the vessel to help retain the elongated member in position, the legs initially extending in a direction away from a top surface of the elongated member and then curving downwardly toward the top surface of the elongated member, each of the legs having a first free end to engage tissue and a second end attached to and extending from the elongated member.
