| 摘要 |
The present invention is primarily directed to a rapid exchange catheter that permits axial movement of an inner conduit within an outer conduit comprising:•an outer conduit;•an inner conduit, suitable for total or partial passage over a guide wire, wherein said inner conduit is movably disposed within the lumen of said outer conduit, wherein the proximal end of said inner conduit is angled such that it pierces the wall of said outer conduit;•means for permitting axial movement of said inner conduit within said outer conduit, such that said movement is not hindered by the passage of the angled proximal part of the inner conduit through said outer conduit; and•means, situated at the proximal end of the outer conduit, for causing axial pushing-pulling movements of said inner conduit. |
