Abstract:

The device comprises a hemostatic staple or bar comprising a bridge and pair of pins. It is designed to be engaged with the pins straddling the edges of the inferior vena cava (“IVC”), and subsequently seated under manual pressure into the underlying bone of the vertebral column. It is intended that one bar each be applied at sites above and below the injured segment of IVC. With the devices properly engaged, the pressure held between the bar and the vertebral column mechanically approximates and fixes the anterior wall of the IVC against the posterior wall, obliterating the lumen, thereby ensuring hemostasis at the isolated (injured) segment of vein. The bars are engaged with a “pusher” or delivery rod positioned perpendicular to the IVC. The delivery rod is preferably engaged to the hemostatic bar by a clip or screw mechanism to allow rapid preparation and deployment, as well as single-handed seating of the device by the surgeon. Following the repair of the IVC, the delivery rod may be re-engaged and the bars removed, or alternatively, in an unstable patient, the bars might be left in place indefinitely.
