SYSTEM AND METHOD FOR VISUALIZING TISSUE WITH AN ICG DYE COMPOSITION DURING ABLATION PROCEDURES

摘要

A system is provided for identifying the sufficiency of lesions formed during a tissue ablation procedure. The system and method include administering an ICG composition to the patient and forming one or more lesions at a surgical site. The method further includes applying energy of a type and in an amount sufficient to cause ICG in the patient to fluoresce. An image of the tissue and lesion at the surgical site is obtained while the ICG fluoresces. The lesion is distinguished from surrounding de novo tissue based on areas of fluorescence to allow a user to evaluate the quality of the lesion.

主权项

1. A tissue ablation system for identification of a lesion formed by directed energy emission at a surgical site of a patient, the tissue ablation system comprising:
a source of an indocyanine green (ICG) composition for delivery into a body of the patient including to the surgical site; a tissue ablation instrument includes an inflatable balloon for contacting tissue and for use at the surgical site and having:
a movable directed first energy emitter configured to emit a variable amount of directed energy for ablating tissue and forming a lesion at the surgical site;a second energy emitter for applying energy of a type and in an amount sufficient to cause the ICG composition to fluoresce; an imaging device that is configured to obtain an image of the surgical site while the ICG fluoresces with the lesion being visually identifiable relative to de-novo tissue based on a lack of observable fluorescence at locations of the lesion, while the de-novo tissue is characterized by areas of fluorescence; and a display for displaying the image; wherein the first and second energy emitter are disposed within the inflatable balloon of the ablation instrument and are movable therein.
