| titleOfInvention | Balloon catheter for drug application |
| abstract | A method, and an apparatus for use in practicing the method, are provided by which a highly concentrated medication or chemotherapeutic agent can be applied locally under sufficient pressure to cause the medication or agent to penetrate into localized tissue or a body lumen. The total volume of medication or agent is quite small, well below levels that might cause an adverse reaction in other parts of the body. The catheter includes a thin wall flexible balloon having two collars and a central region between the collars, when the central regions defines a plurality of regularly spaced minute perforations through which medication may weep at a controlled, low flow rate. The flow rate is controlled by the minute perforations and the diameter of the central region is less than the diameter of the collars. In practicing the method of the invention, the balloon is selected such that the inflated diameter of the collars will correspond to or be slightly greater than the diameter of lumen into which the balloon is placed, and the central region will be slightly less than that lumen diameter, thereby defining a distinct, annular medication reservoir between the balloon and body lumen. The depth of the reservoir reduces the risk of medicine jetting against the vessel lumen if excess pressure is applied. Inflation of the balloon with a medication will cause the medication to weep from the central region of the balloon, consequently filling the reservoir and bathing the lumen walls. After a predetermined time, a sufficient amount of medication will be absorbed by the lumen walls and the balloon will be deflated so that the catheter may be withdrawn from the lumen. The quantity of medication that ultimately flows into the vessel lumen is sufficiently small so as to not cause any other systemic damage to the patient. |
