Method and apparatus for removing blood clots and other objects |
摘要 |
A catheter has a central lumen so that it may be positioned by a guidewire within a tubular structure of the human body. The catheter has attached to its distal end an inflatable cuff featuring an inflation space with a ring-like cross section. A pouch is circumferentially attached to the cuff The catheter features an inflation lumen that is in communication with the inflatable cuff. The proximal port of the inflation lumen receives a syringe so that the cuff may be inflated when the cuff and pouch are positioned within a tubular structure. A filament passes through the inflation space of the cuff and the inflation lumen and exits the proximal port of the inflation lumen. As a result, the cuff may be cinched so that the pouch is closed in a purse-string fashion to capture an object in the tubular structure. The object may then be removed from the patient's body.
