Abstract: A bifurcated catheter and methods of use are disclosed herein. The bifurcated catheter can include a fixed flat wire that is configurable as a stabilization wire. The bifurcated catheter can be configured to improve the initial access and directability by application of a pull force to the stabilization wire, in addition to a push force from the proximal end of the bifurcated catheter. The stabilization wire is anchored once the bifurcated catheter is positioned. The anchored, bifurcated catheter provides stability and pushability to assist the procedural catheter in traversing the tortuous peripheral vasculature.

Abstract: Tortuosity of vessels at or leading to the site of minimally invasive procedures is a problem for conducting such procedures as they increase the difficulty to guide the procedural catheters through tortuous vessels. Methods and apparatus for stabilization of the sheaths and catheters during access, procedures, and withdrawal in these tortuous vessels are disclosed. The apparatus and method for improving access include application of a pull component to the stabilized procedural catheter using a stabilization catheter/wire in addition to a push component from the percutaneous access to make the access easier while enabling use of more flexible catheters and softer wires. These methods and devices address the problems of trauma to the vessels during access, procedure and removal of catheters and wires, improve pushability of softer catheters and wires, and also substantially reduce substantially the procedure time.

Abstract: Systems and methods to provide end to end stabilization support to the operational catheter and reduce the need to stabilize or push from the lateral wall of the aorta during coronary interventions. This reduces the potential for stroke from plaque breaking off the wall of the aorta during intervention procedures. A support and stabilization wire having one end at the femoral percutaneous access and the second end at a radial percutaneous access is established for end to end stabilization. A bifurcated catheter having a wide lumen for procedural catheters and a narrow lumen for the support wire or catheter is advanced over the support wire to the aortic arch. A procedural catheter and a variety of different shaped guide wires may be deployed from the wide lumen of the bifurcated catheter into the right or left coronary artery to accommodate a range of aortic anatomical considerations during the coronary interventions.

Abstract: A guide sheath device with an integrated stabilization wire is provided. The guide sheath device includes an elongate member having a proximal and distal end and a lumen there between and a stabilization wire integrated to the elongate member. The guide sheath is configured to access the lower vasculature via a contralateral percutaneous access. The stabilization wire is configured to exit the vasculature at an ipsilateral percutaneous access and be locked in place at the exit. The proximal end of the guide sheath and the distal end of the stabilization wire being accessible outside the vasculature enable stabilization of the stabilization wire and the guide sheath. The stabilization enables stabilization of procedural catheters and instruments as they access the site of a procedure within the lower vasculature.

Abstract: The use of bifurcated catheter is disclosed for stabilizing working catheters for carotid percutaneous intervention of vessels originating from a tortuous aortic arch, which uses guide wires that used to enable the catheters accessing the left or right carotid arteries (CA). Also disclosed is the use of two independent catheters or a catheter and snare wire within a single sheath, as well as the implementations, associated problems and corrective solutions to the identified problems. Further additional uses of the bifurcated catheter/dual catheter, for access to and treatment of other exemplary tortuous locations where stability of the procedural catheter would make a difference are also disclosed in the current application.
