System and methods for clot dissolution

Clot disruption and dissolution are achieved using a catheter having both an agitator and the ability to deliver a thrombolytic agent. The catheter is introduced to a target region with a blood vessel and the agitator manipulated to engage and disrupt a region of clot therein. 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.

Method and apparatus for uniform electropolishing of damascene ic structures by selective agitation

The present invention pertains to apparatus and methods for planarization of metal surfaces having both recessed and raised features, over a large range of feature sizes. The invention accomplishes this by increasing the fluid agitation in raised regions with respect to recessed regions. That is, the agitation of the electropolishing bath fluid is agitated or exchanged as a function of elevation on the metal film profile. The higher the elevation, the greater the movement or exchange rate of bath fluid. In preferred methods of the invention, this agitation is achieved through the use of a microporous electropolishing pad that moves over (either near or in contact with) the surface of the wafer during the electropolishing process. Thus, methods of the invention are electropolishing methods, which in some cases include mechanical polishing elements.
