Methods, systems and devices for performing multiple treatments on a patient

Abstract

Methods, systems and devices for treating a patient include performing a first treatment to treat a first portion of tissue and performing a second treatment to treat a second portion of tissue. The second portion of tissue is treated at least twenty-four hours after the first portion of tissue is treated. In particular embodiments, the first portion of tissue includes duodenal tissue, and the second portion of tissue includes duodenal or other gastrointestinal tissue.

         2 . A method for treating a patient comprising:
 selecting a patient diagnosed with diabetes;   performing an ablative treatment comprising ablatively treating one or more portions of the gastrointestinal tract of the patient; and   performing a non-ablative treatment comprising non-ablatively treating a portion of the gastrointestinal tract of the patient that is different than the one or more portions treated in the ablative treatment.   
     
     
         3 . The method according to  claim 2 , wherein the portion of the gastrointestinal tract treated in the non-ablative treatment comprises treating a portion of the stomach. 
     
     
         4 . The method according to  claim 2 , wherein the portion of the gastrointestinal tract treated in the non-ablative treatment comprises treating a portion of the ileum. 
     
     
         5 . The method according to  claim 2 , wherein the portion of the gastrointestinal tract treated in the non-ablative treatment comprises treating a portion of the stomach and the ileum. 
     
     
         6 . The method according to  claim 2 , wherein the ablative treatment is performed with a first treatment device, wherein the non-ablative treatment is performed with a second treatment device, and wherein the first treatment device and the second treatment device are dissimilar. 
     
     
         7 . The method according to  claim 6 , wherein the first treatment device is configured to ablate one or more portions of the duodenum via heating of mucosal tissue of the one or more portions. 
     
     
         8 . The method according to  claim 2 , wherein the method is performed to treat a disease or disorder selected from the group consisting of: diabetes; obesity; insulin resistance; a metabolic disorder and/or disease; and combinations thereof. 
     
     
         9 . The method according to  claim 2 , wherein the ablative treatment comprises a treatment selected from the group consisting of: delivery of thermal energy from a balloon filled with fluid at an ablative temperature; RF energy ablation; delivery of an ablative fluid directly to tissue; cryoablation; delivery of laser energy; delivery of sound energy, such as subsonic sound energy or ultrasonic sound energy; and combinations thereof. 
     
     
         10 . The method according to  claim 2 , wherein the method further comprises expanding one or more layers of duodenal tissue. 
     
     
         11 . The method according to  claim 10 , wherein the tissue expansion comprises expansion of duodenal submucosal tissue. 
     
     
         12 . The method according to  claim 2 , wherein the non-ablative treatment is performed at least 24 hours after the ablative treatment is performed. 
     
     
         13 . The method according to  claim 12 , wherein the non-ablative treatment is performed at least 1 week after the ablative treatment is performed. 
     
     
         14 . The method according to  claim 2 , wherein the non-ablative treatment is performed after a time period has elapsed since the ablative treatment, and wherein the time period duration is determined prior to the performance of the ablative treatment. 
     
     
         15 . The method according to  claim 2 , wherein the ablative treatment comprises treating at least a portion of the mucosal layer of the duodenum. 
     
     
         16 . The method according to  claim 2 , wherein the ablative treatment comprises treating at least a full circumferential portion of duodenal mucosa. 
     
     
         17 . The method according to  claim 2 , wherein the ablative treatment and the non-ablative treatment are performed in the same clinical procedure. 
     
     
         18 . The method according to  claim 2 , wherein the ablative treatment and the non-ablative treatment are performed in different clinical procedures.
