Abstract: A steerable electrophysiology catheter includes a shaft having a distal ablation segment with one or more electrodes coupled to a source of electrical energy by a connector extending through the shaft. The distal ablation segment of the shaft is movable between a collapsed configuration sized for percutaneous introduction into the patient and/or endoluminal delivery to the target site and an expanded configuration, in which the distal ablation segment forms a substantially continuous surface transverse to the shaft axis for engaging the heart tissue and creating a linear lesion thereon. The catheter includes one or more force element(s) positioned to apply an axial force between the distal and proximal ends of the ablation segment. The force element(s) provide a sufficiently uniform force against the distal ablation segment to establish continuous contact pressure between the electrodes and the patient's heart tissue. This contact pressure allows the surgeon to engage the entire length of the distal ablation segment against the heart tissue to provide a relatively long linear lesion on this tissue.

Abstract: A variable zone high metal to vessel ratio stent includes a proximal high metal to vessel ratio zone, a central low metal to vessel ratio zone, and a distal high metal to vessel ratio zone. The proximal high metal to vessel ratio zone is deployed with fixation and sealing to healthy tissue of a main vessel superior to branch vessels and an aneurysm. The central low metal to vessel ratio zone is deployed directly on ostai of the branch vessels. However, as the central low metal to vessel ratio zone is highly permeable, blood flows from the main vessel through the central low metal to vessel ratio zone and into branch vessels.

Abstract: When a main stent-graft is placed in a vessel of a patient and a branch vessel is blocked by the main stent-graft, a RF plasma catheter is used to cut out a portion of the graft cloth of the main-stent graft adjacent to an ostium of the branch vessel to be perfused. To ameliorate possible adverse effects associated with the use of the RF plasma catheter, e.g., creation of coagulum, (desiccated, coagulated blood) or perhaps a cut stent strut, a special process using saline flushing, a novel RF plasma catheter with an insulated tip, or a combination of the two is used.

Abstract: A branch prosthesis configured for placement in a branch vessel includes an expandable tubular body portion, an expandable annular flange attached to a proximal end of the body portion, and a sealing sleeve proximally extending from the annular flange. The sealing sleeve is adapted to deform to a generally straight cylindrical hollow shape during implantation. When deployed, the sealing sleeve rolls up to a tightly-wound coil that bears against the annular flange. When used in conjunction with a main prosthesis having a side opening and deployed within in a main vessel, the annular flange of the branch prosthesis engages an outer surface of the main prosthesis around a perimeter of the side opening and the sealing sleeve engages an inner surface of the main prosthesis around the perimeter of the side opening to form a fluid-tight seal between the main prosthesis and the branch prosthesis.

Abstract: RF power is applied to a circular RF electrode cutting a side opening in a graft material of a main stent-graft in situ. As the side opening is formed by the applied RF power and the associated plasma discharge, the side opening is formed with a minimal application of force to the graft material. Further, the side opening is circular and has a fused edge.
