Abstract
A depth and puncture control system for a blood vessel hemostasis system includes a blood vessel puncture control tip which, when positioned in the lumen of a blood vessel, can inhibit the flow of blood out of the puncture site. When used together with a pledget delivery cannula and a pledget pusher, the control tip and the delivery catheter can both inhibit blood loss out the puncture site and inhibit the introduction of pledget material and tissue fragments into the blood vessel. The system also includes a handle which releasably connects together the control tip, pusher, and delivery cannula to permit limited longitudinal motion between the control tip and the delivery cannula, and between the pusher and the delivery cannula.
