First Claim
Patent Images
1. A method of producing a therapeutic agent in a body, the method comprising:
- electrochemically converting at least one substance present in a body fluid flowing in a body lumen into a therapeutic agent by implanting a tubular implant in the body lumen, the implant comprising an uncoated portion and a coated portion, the coated portion coated with an active metal, for electrochemically converting at least one substance present in a body fluid flowing in the body lumen into a therapeutic agent, wherein the implant is implanted with the body lumen such that one of the uncoated portion and the coated portion is disposed upstream of the other relative to the flow of the body fluid in the body lumen, wherein the coated portion and the uncoated portion are directly exposed to the flow of body fluid.

Abstract
A device and method are provided for spontaneous electrochemical production of therapeutic species, in vivo. An active metal is implanted in the tissue. The metal undergoes corrosion, thus acting as a reducing agent to constituents in the tissue, so as to cause these constituents to form the therapeutic agents.

1. A method of producing a therapeutic agent in a body, the method comprising:
electrochemically converting at least one substance present in a body fluid flowing in a body lumen into a therapeutic agent by implanting a tubular implant in the body lumen, the implant comprising an uncoated portion and a coated portion, the coated portion coated with an active metal, for electrochemically converting at least one substance present in a body fluid flowing in the body lumen into a therapeutic agent, wherein the implant is implanted with the body lumen such that one of the uncoated portion and the coated portion is disposed upstream of the other relative to the flow of the body fluid in the body lumen, wherein the coated portion and the uncoated portion are directly exposed to the flow of body fluid. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A method of producing an oxidizing agent in a body, the method comprising:
electrochemically converting at least one substance present in a body fluid flowing in a body lumen into an oxidizing agent by implanting a tubular implant in the body lumen, the implant being partially coated with an active metal, thereby forming a coated portion of the implant and an uncoated portion of the implant for electrochemically converting at least one substance present in a body fluid flowing the body lumen into an oxidizing agent, wherein the implant is implanted within the body lumen such that one of the uncoated portion and the coated portion is disposed upstream of the other relative to the flow of the body fluid in the body lumen, wherein the coated portion and the uncoated portion are directly exposed to the flow of body fluid. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
- 47. A method of reducing cell proliferation in a tissue, the method comprising electrochemically converting at least one substance present in a body fluid flowing in a body lumen into an oxidizing agent by implanting a tubular implant in the body lumen, the implant being partially coated with an active metal, thereby forming a coated portion of the implant and an uncoated portion of the implant for electrochemically converting at least one substance present in a body fluid flowing in the body lumen into an oxidizing agent in an amount sufficient for reducing cell proliferation in the body lumen, wherein the implant is implanted within the body lumen such that one of the uncoated portion and the coated portion is disposed upstream of the other relative to the flow of the body fluid in the body lumen, wherein the coated portion and the uncoated portion are directly exposed to the flow of body fluid.

63. A method of producing nitric oxide in a body, the method comprising:
electrochemically converting at least one substance present in a body fluid flowing in a body lumen into nitric oxide by implanting a tubular implant in the body lumen, the implant being partially coated with an active metal, thereby forming a coated portion of the implant and an uncoated portion of the implant for electrochemically converting at least one substance present in a body fluid flowing the body lumen into the nitric oxide, wherein the implant is implanted within the body lumen such that one of the uncoated portion and the coated portion is disposed upstream of the other relative to the flow of the body fluid in the body lumen, wherein the coated portion and the uncoated portion are directly exposed to the flow of body fluid. - View Dependent Claims (64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83)
