APPARATUS AND METHOD FOR IMPROVED ACCESS OF PROCEDURAL CATHETER IN TORTUOUS VESSELS

Номер: US20200038210A1
Автор: SHAIKH Azim, SYED Mubin I.
Принадлежит: RAM MEDICAL INNOVATIONS, LLC

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. 1. A percutaneous intervention system comprising:a bifurcated catheter comprising a first procedural lumen and a second stabilization lumen, the bifurcated catheter comprising a proximal end and a distal end;a stabilization wire slideably insertable through the stabilization lumen configured to provide end to end stabilization during procedure, the stabilization wire lockable to the distal end of the bifurcated catheter; anda procedural catheter slideably insertable through the first procedural lumen and configured to be delivered to a treatment site for a treatment procedure,wherein the bifurcated catheter is configured to be pushed from the proximal end and pulled from the distal end by the stabilization wire during delivery of the procedural catheter to the treatment site.2. The percutaneous interventional system of claim 1 , wherein the bifurcated catheter is inserted via a first percutaneous access.3. The percutaneous interventional system of claim 2 , wherein the first percutaneous access is a groin access.4. The percutaneous interventional system of ...

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. 1. A system comprising:a bifurcated catheter for enabling access for a procedural catheter to a site in a vasculature, the bifurcated catheter comprising a proximal end and a distal end, and a side hole near the distal end of the bifurcated catheter; anda stabilization wire attached to the bifurcated catheter, wherein the stabilization wire is configured to emerge from the side hole.2.
