发明名称 A Catheter
摘要 A retrieval catheter (1) for retrieval of an embolic protection filter from a vasculature. The catheter (1) comprises a proximal hypotube (3), a radially offset distal shaft (4) and a centring shank. (9). A guidewire lumen (13) is provided through the shank (9) in communication with a larger guidewire lumen (7) through the shaft (4) for a continuous guidewire passageway to accommodate passage of a guidewire (21) through the shank (9), the shaft (4) and out through a proximal guidewire opening (6) to facilitate rapid exchange of the catheter (1) over a guidewire (21). The shank (9) is movable between an introduction configuration in which the shank (9) protrudes distally from the shaft (4) to centre the catheter (1) during advancement through a vasculature, and retrieval configuration in which the shank (9) is located within the guidewire lumen (7) to facilitate retrieval of an embolic protection filter into the shaft (4). <Figure 2>
