Abstract

Systems, devices, and methods for treating a medical condition of a patient are described. The system for treating a medical condition of a patient includes: a catheter for insertion into the intestine, the catheter having an elongate shaft with a distal portion; and a functional assembly positioned on the elongate shaft distal portion and including at least one treatment element. The at least one treatment element treats target tissue located in the small intestine of the patient by delivering electrical energy to the target tissue. The delivery of the electrical energy electroporates cells of the target tissue.
