    摘要： An electrode is provided at a distal end of a catheter and dimensioned for deployment within a renal artery. A deformable cover of the electrode incorporates a force-activatable conduction apparatus. The cover is configured to conduct electrical energy only through a region or regions of the cover subject to deformation due to contact with a wall of the target vessel. The electrical energy is sufficient to ablate perivascular renal nerves proximate the deformed region or regions of the electrode cover. The cover is configured to prevent conduction of electrical energy through the cover in the absence of a deformation force applied to the cover.

    摘要： An elongated flexible medical device is inserted into a patient's body via a natural orifice, and advanced through the natural orifice to a location proximate innervated tissue that influences renal sympathetic nerve activity. The medical device can be advanced into a body organ and to a location within the organ proximate the innervated tissue. The organ may comprise an organ of the gastrointestinal tract or urinary tract. The medical device may be advanced through and beyond an access hole in a wall of the organ, and situated at a location proximate the innervated tissue. One or both of imaging and ablation energy is delivered from a distal end of the medical device to the innervated tissue. Innervated renal tissue can be ablated using various forms of energy, including RF energy, ultrasound energy, optical energy, and thermal energy.

    摘要： The present invention relates to a support structure/membrane composite device which includes a support structure, such as a radially expandable stent, a porous non-textile polymeric membrane adjacent to said stent and a thermoplastic anchor means attaching said stent to said porous non-textile polymeric membrane. The porous non-textile polymeric membrane is preferably made from expandable fluoropolymer materials. The anchoring means is a thermoplastic material which is dissolvable at the interface between the support structure and membrane by a suitable solvent which wets the membrane surface and deposits the thermoplastic material within the pores of the membrane. Methods of preparing the device are also disclosed.

    摘要： A composite intraluminal device is deployable within a body vessel. The composite device includes an elongate radially expandable tubular stent having an interior luminal surface and an opposed exterior surface extending along a longitudinal stent axis. A stent cover is formed of unsintered ePTFE which is expandable. The stent cover is positioned about the stent so as to permit expansion of the cover upon the radial expansion of the stent.
