Abstract
Treatment of aneurysmal blood vessels with local delivery of therapeutic agents thereby reduces or lessens the severity of an aneurysm, and, where used in conjunction with the placement of an excluding device, provides for more rapid recovery of the blood vessel from any disturbance occurring during placement of the excluding device. Therapeutic agents are placed in the aneurysmal site in a time-release carrier medium, such that the therapeutic agent is released into the aneurysmal site over a period of time without the need to provide systemic introduction of the therapeutic agent. The carrier may be introduced through the patient's dermis, such as with the use of a laparoscope, or intravacularly, through the use of a catheter. The carrier may be in a solid matrix, viscous liquid or liquid form.
