Abstract

Catheters for introducing fluids into a bodily lumen of a patient are disclosed. The fluids may include medicinal, imaging or other compounds. The catheters include a proximal tube, a core wire and a distal tube. The first end of the core wire is secured to the second end of the proximal tube. The core wire extends through the distal tube. A proximal lumen of the proximal tube is in communication with the distal lumen of the distal tube. A bridge tube may be provided between the proximal lumen and the distal lumen to facilitate communication of the proximal lumen and the distal lumen. The catheter may be configured with a relatively small diameter and low overall profile using aspects of the present inventions. The catheters may include a balloon at a distal end to receive the fluid. The fluid provided through the catheter may inflate the balloon. The catheter may include a distal outlet release a fluid into the patient.
