Claim Text:
1. A thrombus removal system comprising: an axially elongate catheter tube having a proximal end, a distal end, and comprising a central lumen and a pressurization lumen extending from the proximal end toward the distal end; a fluid infusion port at the proximal end operably connected to the pressurization lumen of the catheter tube; a through port operably connected to the central lumen of the catheter tube; an expandable structure proximate the distal end of the catheter tube capable of enlarging or reducing in lateral dimension in response to axially longitudinal movement of a proximal end of the expandable structure relative to a distal end of the expandable structure, the proximal end of the expandable structure slidable along the catheter tube while having a constant diameter whether the expandable structure is enlarged or reduced in size, and the distal end of the expandable structure being fixed relative to the catheter tube; a bladder affixed at one end to the proximal end of the expandable structure and at another end to the catheter tube, wherein an inner volume of the bladder exists between the bladder and the catheter tube; and a pressurization port operably connecting the pressurization lumen with the inner volume between the bladder and the catheter tube.
