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: 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.

Abstract: For percutaneous minimally-invasive intervention in vessels originating from other tortuous vessels, such as the tortuous aortic arch, guide wires/catheters are used to enable procedural catheters to access the vessels where an interventional procedure is needed. Two new methods for fixing a stabilization wire/catheter and providing the needed tension and stabilization without a second percutaneous access are disclosed (1) using a micro-anchor and pin and (2) using a modified Fogarty Balloon. These methods are also usable for access to and treatment of peripheral embolisms in tortuous vessels as well as renal and other visceral interventions.

Abstract: A system for the intravascular placement of a medical device including a guidewire having a first end and a second end, the first end having a microwhisk positional between a feeding state and a deployed state, a guidewire sheath surrounding the guidewire; and an anchoring device for cooperatively fixing the microwhisk relative to a patient. Also, the method of the intravascular placement of the medical device by inserting the medical device through the body with the guidewire and the microwhisk contained within the guidewire sheath, driving the microwhisk out of the guidewire sheath to position the microwhisk to its deployed state, and engaging the anchoring device from the outside of the body through a body surface into the microwhisk, and further into a stabilizing body component.

Abstract: A steerable intravascular anchor comprises an anchor portion that is steerable to a position and then pinned thereto by an external device protruding through the superficial temporal artery. The pin is steered through the skin into the anchor under, for example, by fluoroscopic guidance. The anchor portion, in one embodiment, may have a figure-eight shape, and that comprises two wires, each wire forming a ring. The rings may be located in the same plane or at an angle with respect to one other. Alternatively, the anchor portion comprises a plurality of wires, each wire forming a ring, each ring being connected to at least one other ring. It will be appreciated that other wire shapes may be used, including loops, triangles, squares, pentagons, hexagons, and the like, and combinations thereof.

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: 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.

Abstract: Systems and methods for addressing the percutaneous intervention related trauma to the vessels that arise from type-III hostile aortic arches, from uncontrolled prolapse of sheaths, embolic protection devices and stent delivery systems, by stabilizing the systems while stenting of the left and right carotid arteries. Guide wires to stabilize catheters used to access the left or right carotid arteries (CA) for carotid percutaneous intervention of the vessels originating from a tortuous aortic arch are disclosed. A bifurcated catheter for stabilizing the catheters is also disclosed. The bifurcated catheter has a main catheter that divides into two separate catheters forming a “Y” shape. One leg of the catheter has a smaller diameter with a smaller working lumen (inner diameter) to carry the stabilizing wire and the other leg of the catheter has a larger working lumen for arterial stenting operations.
