摘要：
A system for treating a blood clot includes a microcatheter extending through an optional aspiration catheter, and a guidewire subassembly extending through and beyond the microcatheter, the guidewire assembly having a guidewire, an element coupled to and extending around a portion of the guidewire, and a balloon coupled to and extending around the element. The balloon includes or is coupled to a proximal seal in contact with the inner surface of the microcatheter and has at least one radially arranged pore. Infusate flows through the microcatheter into the element and between the element and the guidewire, and out and into the balloon to pressurize the balloon. The infusate escapes the balloon through the pores.
