| 摘要 |
The invention provides a catheter assembly (20) including a catheter (21) having an elongate main body (22) extending longitudinally between proximal and distal ends. A top structure (26) is attached to the distal end of the main body and also extends longitudinally. The main body and tip structure combine to define side-by-side intake (28) and return (30, 51) lumens and the intake lumen terminates at a transverse intake opening (44) at the distal end of the main body. The return lumen terminates at the distal end of the tip structure at a transverse return opening (46) and a side opening (52) is provided adjacent the return opening. The assembly also includes a tubular applicator (54) which passes through the intake lumen, through the side opening and into the return lumen. This permits the assembly to be passed over a guide wire (55) by engaging the guide wire inside the tubular applicator and sliding the assembly over the guide wire. <IMAGE> |
