Abstract
A method for open surgical repair of a damaged portion of an artery or vein. A tubular medical assembly may include one or more shaped members, such as microbarbs, configured to anchor into the tunica intima and the tunica media of the vessel wall, and not to the tunic adventitia and vasa vasorum. The medical assembly is delivered to the damaged vessel portion via a delivery device through an open air pathway, and forms a conduit between transected ends of the damaged vessel.
Claims16
A method for open surgical repair of a damaged portion of a body vessel having a vessel wall defining a lumen, the vessel wall including a tunica intima, a tunica media, and a tunica adventitia, the steps comprising:
- providing a medical device including a first connector and a second connector and a tubular conduit, the tubular conduit having a wall defining a lumen about a longitudinal axis between a first axial end and a second axial end, and the first and second connectors disposable with the respective first and second axial ends of the tubular conduit, each of the first and second connectors having a first portion engageable with the wall of the tubular conduit, and a second portion having a plurality of shaped members dimensioned and arranged therealong to penetrate and anchor into the vessel wall;
- transecting said body vessel to form a first portion and a second portion of said body vessel;
- deploying the first and second connectors of the medical device into the respective first and second portions of said body vessel with a delivery system, such that the shaped members of the first and second connectors penetrate and anchor into the tunica intima and tunica media of the respective first and second body vessel portions, and not into the tunica adventitia;
- and
- engaging the first axial end of the tubular conduit to the first connector and the second axial end of the conduit to the second connector to form the medical device to repair the damaged portion of the body vessel.
A method for open surgical repair of a damaged portion of a body vessel of a patient, the body vessel having a vessel wall including a tunica intima, a tunica media, and a tunica adventitia, comprising:
- loading a medical assembly onto a delivery system for deployment at said damaged vessel portion, the medical assembly comprising a tubular conduit having a first axial end and a second axial end, and a first connector disposed at said first axial end, said first connector comprising a first portion engaged with the first axial end of the tubular conduit and a second portion having a plurality of microbarbs dimensioned and circumferentially arranged along a surface thereof to penetrate and to anchor into the wall of said body vessel;
- transecting said damaged body vessel through an open surgical pathway to form a first end portion and a second end portion of said body vessel;
- advancing an end of the delivery system through the open surgical pathway into said first end portion of the body vessel such that said microbarbs penetrate and anchor into the tunica intima and tunica media of the body vessel wall, and not into the tunica adventitia;
- removing said delivery system end from the first vessel end portion;
- loading a second connector onto said delivery system, said second connector comprising a first portion engageable with the second axial end of the tubular conduit and a second portion having at least one shaped member dimensioned and arranged along a surface thereof to penetrate and to anchor into the wall of said body vessel;
- advancing an end of the delivery system through the open surgical pathway into said second end portion of the body vessel such that the at least one shaped member of the second connector penetrates and anchors into the body vessel wall;
- and
- joining the first portion of the second connector with the second axial end of the tubular conduit.
A method for open surgical repair of a damaged portion of a body vessel of a patient, the body vessel having a vessel wall including a tunica intima, a tunica media, and a tunica adventitia, comprising:
- transecting the body vessel at said damaged portion through an open air surgical pathway to form a first vessel end portion and a second vessel end portion;
- positioning a first connector for insertion through said open air pathway, said first connector comprising a first portion and a second portion, said second portion having at least one shaped member dimensioned and arranged along a surface thereof to penetrate and anchor into a wall of the first vessel end portion, said at least one shaped member of said first connector comprising a plurality of microbarbs spaced along a circumference of said surface, and inserting said second portion of said first connector through said open air pathway into said first vessel end portion a distance such that said microbarbs penetrate and anchor into the tunica intima and tunica media of said wall of said first vessel end portion, and not into the tunica adventitia;
- positioning a second connector for insertion through said open air pathway, said second connector comprising a first portion and a second portion, said second portion having at least one shaped member dimensioned and arranged along a surface thereof to penetrate and anchor into a wall of the second vessel end portion, and inserting said second portion of said second connector through said open air pathway into said second vessel wall portion a distance such that said at least one shaped member penetrates and anchors into said wall;
- inserting a first axial end of a tubular conduit through said open air pathway and thereafter joining said first axial end with the first portion of the first connector;
- and
- joining a second axial end of the tubular conduit with the first portion of the second connector.
