VASCULAR CONDUIT AND DELIVERY SYSTEM FOR OPEN SURGICAL PLACEMENT
First Claim
1. A device for intraoperative repair of a damaged portion of a body vessel, the body vessel having a vessel wall including a tunica intima, a tunica media, and a tunica adventitia, comprising:
- a tubular conduit having a wall defining a lumen about a longitudinal axis between a first axial end and a second axial end; and
a first connector and a second connector disposed at 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 at least one shaped member extending radially therefrom, the at least one shaped member dimensioned and arranged along the second portion to penetrate and anchor into said tunica intima and tunica media of said vessel wall upon insertion of said device into said body vessel.

Abstract
A vascular conduit device and a delivery system for intraoperative repair damaged portion of an artery or vein and methods of use are provided. The device has a cylindrical body and may include a shaped member, such as a microbarb, configured to anchor into the tunica intima and the tunica media of the vessel wall, and not to the tunic adventitia and vasa vasorum. Various configurations and orientations of the microbarbs are provided, including microbarbs that are preferably aligned at an acute angle in the range of about 5 to 30 degrees and having a substantially parallel surface. The delivery system preferably has a translatable dilator tip that when retracted is configured to engage with the device during delivery. When the dilator tip is extended, the device can be implanted into the vessel wall. The vascular conduit device can be assembled during the emergency open surgical procedure.

10. A delivery system for deploying a tubular medical device in a body vessel, the tubular medical device having a proximal end and a distal end and a lumen therebetween, the delivery system comprising:
-
an elongated tubular member having a lumen about a longitudinal axis and a proximal end and a distal end, the elongated tubular member sized to extend through the lumen of said tubular medical device; a handle attached to the proximal end of the elongated tubular member, the handle having a lumen about the longitudinal axis and a proximal end and a distal end, the lumen of the handle in communication with the lumen of the elongated tubular member; a dilator tip disposed at the distal end of the elongated tubular member, the dilator tip sized and configured to receive the distal end of the elongated tubular member and to engage the distal end of said tubular medical device; and a controller to manipulate the dilator tip disposed at the handle, the controller including a control member extending through the lumens of the respective elongated tubular member and the handle, the control member having a distal end attached to the dilator tip and a proximal end attached to the controller, wherein the controller is configured to retract the dilator tip in a proximal direction to a retracted position and to extend the dilator tip in a distal direction to an extended position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of delivering a medical device system for intraoperative repair of a damaged portion of a body vessel having a vessel wall defining a lumen, the steps comprising:
-
providing a medical device system 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 at least one shaped member dimensioned and arranged along the second portion to penetrate and to anchor into the vessel wall of said body vessel; 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 system into the respective first and second portions of said body vessel with a delivery system; and engaging the tubular conduit to the first connector and the second connector to form the medical device system to repair the damaged portion of the body vessel intraoperatively.
