Enhanced System for Treating Bifurcations with Minimized Vessel Trauma

An improved system and method for treating bifurcated vessels, minimizing vessel trauma and reducing the risk of guidewire entanglement, thereby enhancing patient safety and treatment outcomes.

The original patent disclosed a system and method for treating bifurcated vessels using two delivery catheters and stents. However, this approach had inherent limitations, including the potential for vessel trauma and guidewire entanglement. The present inventive concept addresses these limitations by introducing a novel system and method that enables simultaneous advancement of the delivery catheters against the carina of the bifurcation, reducing vessel trauma and the risk of guidewire entanglement.

The enhanced system for treating bifurcations comprises two delivery catheters, each having an expandable member and a stent disposed over the expandable member. The delivery catheters are designed to be simultaneously advanced against the carina of the bifurcation, thereby minimizing vessel trauma. The system may also include a single guidewire, over which both delivery catheters are advanced, reducing the risk of guidewire entanglement. The method of treating a bifurcation using this system involves advancing the delivery catheters simultaneously against the carina of the bifurcation and deploying the stents from the delivery catheters, treating the bifurcation in a single procedure. The system and method may be used under fluoroscopic guidance, enabling real-time visualization of the bifurcation treatment.

The present inventive concept introduces the novel feature of simultaneous advancement of the delivery catheters against the carina of the bifurcation, reducing vessel trauma and the risk of guidewire entanglement. This is a significant improvement over the original patent, which did not provide for simultaneous advancement of the delivery catheters. The use of a single guidewire and the alignment of the proximal ends of the stents to create a continuous, unobstructed lumen across the bifurcation are also novel and non-obvious features of the present inventive concept.

Alternative embodiments of the inventive concept may include variations in the design of the delivery catheters, such as using different materials or geometries. The system may also be adapted for use in other types of bifurcations, such as those found in coronary or peripheral vessels. Additionally, the system may be used in conjunction with other medical devices, such as balloons or atherectomy devices, to enhance the treatment of bifurcations.

The enhanced system for treating bifurcations has significant commercial potential in the medical device industry, particularly in the fields of interventional cardiology and peripheral vascular disease. The system's ability to minimize vessel trauma and reduce the risk of guidewire entanglement makes it an attractive solution for clinicians and patients alike. The market for bifurcation treatment systems is expected to grow as the prevalence of vascular disease continues to increase, and the present inventive concept is well-positioned to capture a significant share of this market.
