| 摘要 |
Disclosed is an infusion device (10) and a method of use thereof comprising the steps of, and means for, introducing an elongated infusion device (10) having an elongated body, an internal lumen, and a distal infusion segment (22) through a patient's vascular system to the site of an obstruction (14), the infusion device (10) having an infusion port in the distal infusion segment (22) leading to the infusion lumen for infusing a dissolving agent in proximity with the obstruction (14), applying force axially along the body of the infusion device (10) against the resitance of the obstruction (14), thereby storing potential energy in the infusion device (10), delivering the dissolving agent through the infusion device lumen and out of the infusion port and into the obstruction (14), and longitudinaly extending the infusion device (1) distally under the force of the potential energy as the resistance of the obstruction (14) diminishes as it is dissolved.
