Apparatus and methods for clot dissolution

Clot disruption and dissolution are achieved using a catheter having the ability to infuse a thrombolytic agent, aspirate clot and fluid, and allow passage of a guidewire. Optionally, the catheter may also include a mechanical agitator for further disrupt clot in the presence of the thrombolytic agent. A flow resistor in the catheter provides for infusion and/or aspiration to be concentrated primarily at a clot treatment area in a blood vessel while also providing optional infusion and/or aspiration distal to the treatment area. In some embodiments, infusion, aspiration and guidewire passage occur through a common lumen. The thrombolytic agent, such as tPA, streptokinase, or urokinase, is directly released into the clot at the point where the agitator is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.

Long Catheter Infusion Insertion Method and Apparatus

A long catheter can be inserted into a patient while eliminating the need for a sterile field by incorporating the long catheter into an infusion tubing and carrying it in with the infusion. The long catheter has a structure that prevents it from leaving the infusion set when fully extended and therefore becomes a connector for fluids to transfer down the long catheter by infusion through the infusion set. Use of an adjustable seal connector allows the catheter to be stopped at varying points during insertion and even to allow the catheter to be reversed by pulling suction on the infusion set and retracting the catheter back into the tubing. This also remains within the sterile confines of the infusion set and therefore is prevented from becoming contaminated.
