Radio-opaque hemostatic agents and devices and methods for the delivery thereof

摘要

A radiographic composition for promoting the formation of clots in blood includes a zeolite and iodine. A device for promoting the clotting of blood at an internal wound site includes a catheter; a delivery instrument insertable through the catheter; a radioopaque blood clotting agent that deliverable through the delivery instrument; and a positive pressure apparatus that can dispense the blood clotting agent to the wound site through the delivery instrument. A system for radiographically imaging an internally bleeding wound includes means for delivering a radioopaque blood clotting agent and means for radiographically imaging the radioopaque blood clotting agent. A method of imaging an internally bleeding wound includes the steps of inserting a catheter into a patient; advancing the catheter to a point adjacent the bleeding wound; depositing a radioopaque zeolite at the bleeding wound; and imaging the radioopaque zeolite to monitor blood-clotting caused by the zeolite.
