METHODS AND APPARATUS FOR ANALYZING AND LOCALLY TREATING A BODY LUMEN
First Claim
1. An apparatus for probing and treating internal body organs comprising:
- a catheter having a fiber probe arrangement and one or more treatment lumens;
a needle-tip inserter integrated with said fiber probe arrangement and said one or more treatment lumens;
a spectrometer connected to said fiber probe arrangement;
an analysis and treatment control system connected to said catheter and spectrometer, said analysis and control system programmed to characterize and locate damaged tissue within a wall of a body lumen and to treat said damaged tissue with said needle-tip inserter and said one or more treatment lumens.

Abstract
A method and apparatus for analyzing and treating internal lumens is provided. The apparatus includes a catheterized device integrating an optical probe and local treatment delivery system. The probe component includes fiber optic lines that can be used in conjunction with visible and/or near infrared spectroscopy to analyze various characteristics of tissues, including chemical, blood, and oxygen content, in order to locate those tissues associated with diseased lumens, to determine the best location for applying treatment, and to monitor treatment and its effects. Physically integrated with the probe component is a treatment component for delivering localized treatments including stem cells, antibiotics, gene therapy, neoplasty, and sclerosant drugs, etc. A control system coordinates operation of the catheter, including performing chemometric analysis with the use of model data, and for providing control and visual feedback to an operator.

10. A method for treating a body lumen, said method comprising:
-
inserting into a patient'"'"'s lumen a catheter integrated with a fiber optic analysis probe, an integrated inserter for perforating targeted tissue, and a treatment delivery conduit; characterizing and locating the tissue of the lumen to be treated with radiation delivered and collected through said fiber optic analysis probe; positioning said inserter to perforate targeted tissue and deliver treatment with information obtained through said fiber optic analysis probe; and injecting a therapeutic agent through said treatment delivery conduit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
