SHIELDED TIP CATHETER

摘要

A multi-lumen catheter assembly is disclosed. The assembly includes an elongated body (108) having a proximal end (102) and a distal end (104) and a first lumen (110) having a sidewall (118) extending between the proximal end (102) and the distal end (104), a first distal opening (151) disposed at the distal end (104), and a first guide wire opening (152) disposed proximally of the distal end (104) and co-planar with the sidewall (118). The assembly also includes a second lumen (112) connected to the sidewall (118) and extending from the proximal end (102) toward the distal end (104), proximally of the distal end (104). The second lumen (112) includes a second opening (115) extending obliquely away from the sidewall (118) distally toward the first distal opening (151) and a second guide wire opening (156) disposed proximally of the second opening (115) and in a plane generally parallel to the sidewall (118). A method of inserting the catheter into a vessel is also disclosed.
