| 摘要 |
An introducer catheter includes a percutaneously insertable shaft (23) which is configured to engage and to be supported by the inner luminal surface (21) of a blood vessel (20). The distal tip (30) of the catheter shaft is disposed along a central axis (28) of the catheter such that when the catheter is disposed in the blood vessel (20), the distal tip (30) will be disposed substantially along that axis and substantially in the center of the blood vessel lumen. The probe (16) passed through the catheter thus will emerge from the distal outlet orifice (32) of the catheter into the blood vessel at the central axis of the blood vessel (20). <IMAGE> |
