      tPA by Endovascular Administration for the Treatment of Submassive PE Using CDT for the Reduction of Thrombus Burden
      Recruiting
                          Multiple Locations
        The BashirTM Endovascular Catheter has been designed to administer therapeutic agents in the peripheral vasculature. Because of the unique design of the catheter, with its six expandable infusion limbs, the BashirTM Endovascular Catheter has the ability to: 1. Create a much larger central channel for blood flow, thereby utilizing the body's own endogenous fibrinolytic agents to lyse the clot, and 2. Greatly enhance the radial dispersion of a catheter-administered thrombolytic agent throughout the thrombus. Expansion of the multiple arms of the basket in the infusion catheter causes fissuring of the clot. The net result is that a greater surface area of clot is exposed to both endogenous and exogenously administered lytic agents, thereby promoting clot dissolution.

    A Study to Analyze the Role of Sympathetic Nervous System in Spontaneous Coronary Artery Dissection
      Recruiting
                          Minnesota
        Have you had a heart attack caused by spontaneous coronary artery dissection (SCAD)? Most patients with SCAD do not have traditional risk factors such as tobacco use, high cholesterol, diabetes, but rather, they the heart attack is caused by other problems with the heart. In this clinical trial, researchers are studying people who have had SCAD to understand what may cause this to happen. The study is taking place in Rochester, Minnesota.
