Drug solution infusion catheter

摘要

A drug solution infusion catheter includes a distal end wall made of an elastic material. The distal end wall closes a distal end surface of the catheter. A center portion of the distal end wall is thinner than a peripheral edge portion of the distal end wall. The center portion of the distal end wall defines a hole or an incision. The hole or the incision closes normally. When a guide wire is pressed against the hole or the incision from an inner side of the catheter or an outer side of the catheter, the hole or the incision elastically opens to allow the guide wire to pass therethrough. An outside of the peripheral edge portion of the distal end wall makes up the distal end surface of the catheter.
