  • Patent number: 6865416
    Abstract: The invention provides methods for inducing or increasing the vasodilation of a vessel. The invention further provides methods for inducing or increasing the flow of fluid through a vessel. An electrical impulse is applied to the vessel in order to induce or increase vessel vasodilation or to induce or increase the flow of fluid through the vessel. In a particular embodiment, a novel double-balloon catheter system incorporating electroporation technology has been designed and is used to apply the electrical impulse endoluminally.

  • Publication number: 20020183684
    Abstract: The present invention provides methods for inhibiting or preventing hyperplastic intimal growth by intravascular administration of a composition comprising heparin, or a derivative thereof in conjunction with at least one electric pulse having sufficient strength and duration to cause electroporation of the cells lining the blood vessel. Such treatment inhibits or prevents hyperplastic intimal growth in vessels, such as arteries, as compared with a non-electroporated vessel to which the heparin, or derivative thereof, is administered.

  • Patent number: 6233482
    Abstract: A method and apparatus for in vivo electroporation therapy. Using electroporation therapy (EPT) as described in the invention, tumors treated by a combination of electroporation using the apparatus of the invention and a chemotherapeutic agent caused regression of tumors in vivo. In one embodiment, the invention provides a method of EPT utilizing low voltage and long pulse length for inducing cell death. One embodiment of the invention includes a system for clinical electroporation that includes a needle array electrode having a “keying” element that determines the set point of the therapy voltage pulse and/or selectable array switching patterns. A number of electrode applicator designs permit access to and treatment of a variety of tissue sites. Another embodiment provides a laparoscopic needle applicator that is preferably combined with an endoscope for minimally invasive EPT.
