Systems and methods for applying a selected treatment agent into contact with tissue
View Patent ↗Systems and methods that treat disorders of the gastrointestinal tract by applying one or more treatment agents to tissue at or near the region where abnormal neurological symptoms or abnormal tissue conditions exist. The treatment agent is selected to either disrupt the abnormal nerve pathways and/or to alleviate the abnormal tissue conditions. The treatment agent can include at least one cytokine and/or at least one vanilloid compound to evoke a desired tissue response. The systems and methods can be used a primary treatment modality, or as a neoadjuvent or adjuvant treatment modality.
1. A method of treating tissue within a body comprising
selecting at least one treatment agent comprising at least one of a vanilloid compound and a cytokine compound,
providing a source of the treatment agent,
deploying an endoscope to a targeted tissue region the endoscope having an interior lumen,
visualizing the targeted tissue region with the endoscope,
deploying through the interior lumen of the endoscope a catheter carrying on its distal end a tissue-piercing element adjacent to the targeted tissue region visualized by the endoscope,
coupling the catheter to the source of the treatment agent, and
applying through the tissue-piercing element the treatment agent into contact with the targeted tissue region visualized by the endoscope.
2. A method according to claim 1
wherein the applying includes injecting the treatment agent into subsurface tissue in the targeted tissue region.
3. A method according to claim 1
further including providing a guide wire to facilitate deployment of the endoscope and/or catheter.
