AI Technical Summary

Technical Problem

Existing minimally invasive tissue ablation techniques are difficult to effectively treat targeted tissues, especially gastrointestinal tissues, and traditional electrode treatment systems lack flexibility in deployment and treatment, making it difficult to meet the needs of multi-regional treatment.

Method used

Employing a rollable flexible substrate design, the electrodes are deployed and retracted through independent driving elements. Combined with reversible electroporation and electrolysis technologies, it promotes the ablation and regeneration of targeted tissues.

Benefits of technology

This system enables compact deployment and flexible treatment of the electrode therapy system, reduces invasiveness to patients, improves treatment efficiency, promotes tissue regeneration and the formation of healthy tissue, and avoids the formation of scars and fibrosis.

Abstract

Devices, systems, and methods for providing controlled delivery of electrolytes and cell permeabilization therapy to a tissue site are disclosed. Systems, devices, and methods may include designs having features for efficiently deploying a flexible substrate having an electrode at a tissue site for treatment and for facilitating retraction of the electrode into a housing for removal after completion of treatment. The systems, devices, and methods may further include an expansion member for radially expanding the flexible substrate to assist in positioning the electrode adjacent tissue to facilitate treatment.
