Abstract
The present invention contemplates a surgical device for both ablating a channel in a patient's tissue and also delivering a therapeutic agent. The device includes an elongated multi-lumen tube, an elongated tissue ablating assembly, and a therapeutic agent delivery assembly. The therapeutic agent is capable of being delivered into the channel and/or to the surrounding tissue. The device may further include a second multi-lumen tube also capable of delivering therapeutic agents. Although suitable for many operations, the device is particularly well suited for transmyocardial revascularization operations. The present invention also contemplates a procedure for using such a surgical device to ablate a channel in a patient's tissue and also deliver a therapeutic agent.
