System for gas treatment of a cell implant
First Claim
1. A system for gas treatment of a cell implant, the system comprising:
- (a) an electrochemical device, the electrochemical device being configured to output a first gas from a first outlet and a second gas from a second outlet, wherein the first gas and the second gas are different from one another,(b) an implantable cell container, the implantable cell container comprising a first chamber configured to receive cells,(c) a first gas conduit for delivering the first gas from the electrochemical device to the implantable cell container, the first gas conduit comprising a first end and a second end, the first end of the first gas conduit being fluidly coupled to the first outlet of the electrochemical device, the second end of the first gas conduit being configured to deliver the first gas to the first chamber of the implantable cell container, wherein the second end of the first gas conduit is disposed within the implantable cell container, and(d) a second gas conduit for delivering the second gas from the electrochemical device to the implantable cell container, the second gas conduit comprising a first end and a second end, the first end of the second gas conduit being fluidly coupled to the second outlet of the electrochemical device, the second end of the second gas conduit being configured to deliver the second gas to the first chamber of the implantable cell container, wherein the second end of the second gas conduit is disposed outside of the implantable cell container.

Abstract
System for gas treatment of cellular implants. The system enhances the viability and function of cellular implants, particularly those with high cellular density, for use in human or veterinary medicine. The system utilizes a miniaturized electrochemical gas generator subsystem that continuously supplies oxygen and/or hydrogen to cells within an implantable and immunoisolated cell containment subsystem to facilitate cell viability and function at high cellular density while minimizing overall implant size. The cell containment subsystem is equipped with features to allow gas delivery through porous tubing or gas-only permeable internal gas compartments within the implantable cell containment subsystem. Furthermore, the gas generator subsystem includes components that allow access to water for electrolysis while implanted, thereby promoting long-term implantability of the gas generator subsystem. An application of the system is a pancreatic islet (or pancreatic islet analog) implant for treatment of Type 1 diabetes (T1D) that would be considered a bio-artificial pancreas.
