    摘要: A support catheter that can puncture a heart septum with a guidewire without buckling and that can access difficult to reach arteries such as carotid or renal arteries from the aorta under difficult circumstances is provided. The support catheter comprises a catheter body having a proximal end, a distal end, and an interior wall surface defining a first lumen extending from the proximal end toward the distal end. A second lumen is disposed between the interior wall surface and an outer surface of the catheter body. A plurality of stiffening members is disposed around the second lumen, the plurality of stiffening members being engageable to selectively stiffen the catheter body. In another configuration, the catheter further comprises a second plurality of stiffening members disposed between the first lumen and the second lumen.

    摘要: A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.

    摘要: This invention describes a guidewire placement device for facilitating the delivery of multiple guidewires to the branches of a tubular system. The invention also includes a method for placing guidewires in the branches of a tubular system using a device in accordance with the present invention, while mitigating guidewire entanglement. The present invention may be utilized during percutaneous treatment of vascular and non-vascular disease, and in particular to complement the use of balloon angioplasty and the deployment of balloon-expanded or self-expanding stents into a bifurcated vessel system.

    摘要: A contoured intraluminal stent for deployment proximate a bifurcated vessel is disclosed. The contoured stent is configured to seat within a side branch of the bifurcated vessel so as to acceptably cover a curvilinear ostium defined at the intersection of the side branch with a main branch of the vessel. A stent deployment system includes a first guidewire positioned in the vessel main branch and a second guidewire that extends through the main branch and into the vessel side branch, wherein the intersection of the branches defines an ostium having a three-dimensionally curvilinear shape. A balloon catheter is tracked along the second guidewire to a position in the side branch proximate the ostium. A contoured stent disposed about the balloon includes a proximal end that defines a curvilinear profile that at least approximately matches the curvilinear shape of the ostium when the stent is deployed in the side branch.
