AI Technical Summary

Problems solved by technology

It has been found to be difficult to place these coils in the exact desired position because of the relative lack of stability of the deployment device within the vessel during the introduction of the embolic coil to an aneurysm.

Embodiment Construction

[0023]FIG. 1 generally illustrates the construction of a preferred embodiment of the delivery catheter of the present invention which generally comprises a dual lumen catheter 10 having a “Y” connector 12 coupled to the proximal end of the catheter. More particularly, the dual lumen catheter includes a first lumen 14 and a second lumen 16. The second lumen 16 extends from the proximal end of the catheter to the distal end of the catheter and also communicates with a lumen 18 which extends from the distal end to the proximal end of the “Y” connector 12. As illustrated, a side opening 20 extends from the second lumen 16 through the side wall of the catheter at a position which is slightly proximate the distal tip of the delivery catheter 10. This side opening, as will be subsequently explained in more detail, serves to permit the introduction of an embolic coil deployment device into an aneurysm for placement of an embolic coil into the aneurysm.

Abstract

A method and apparatus for placing a medical agent, such as an embolic coil into a vessel, or aneurysm, by utilizing a stabilizing catheter to retain or support a medical agent deployment device.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention concerns a novel method and apparatus for placing a medical agent into a vessel of the body, and in particular concerns a novel method for placing embolic coils within an aneurysm of the brain. [0003] 2. Description of the Prior Art [0004] The use of embolic coils placed within an aneurysm for treating the aneurysm within the brain is well known. Various devices are known for delivering embolic coils through the patient's vessel to the aneurysm. Typically these embolic coils, which generally take the form of helically wound coils, or random wound coils, are carried by a coil deployment device which serves to introduce the coils into the aneurysm. The coils are then released by the coil deployment device using one of various types of release mechanisms. [0005] An example of such a coil deployment device is disclosed in U.S. Pat. No. 6,113,622 entitled, “Embolic Coil Hydraulic Deployment System”, issued...
