Core-to-tip heavier-weight wire with a polymer-wrapped tip to access highly stenosed lesions

Jul 29, 2019 · Antegrade wiring (also called antegrade wire escalation) is the most widely used CTO crossing technique. 31,60–62 Various guidewires are advanced in the antegrade direction (original direction of blood flow). Guidewire choice depends on CTO characteristics.

Boston Scientific brings you the one proven system for bridging coronary CTOs via the true lumen or subintimal pathways. Designed to quickly and safely deliver a guidewire via true lumen or subintimal pathways, CrossBoss gives you total access to coronary chronic total occlusions.

All HI-TORQUE™ Guide Wires are intended to facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). Refer to the device label for any additional product-specific indications that may apply.

While not necessary for expert use, understanding basic guidewire construction provides insights that can aid operators to assemble a manageable range of wires in their laboratories, make rational wire choices for specific procedural needs, and create a framework for analyzing wirebased CTO failures.

Length, diameter, gram strength, and hydrophilic coating are important wire characteristics that should be taken into account when crossing a lesion. This article presents a few strategies for wire escalation as well as techniques to successfully cross and treat CTOs encountered when treating patients with CLI.

For a focal lesion (<10–20 mm length), tapered, straight CTO without a side branch, the first choice is a soft, tapered, polymer-coated wire for initial (micro) channel tracking. However, it is essential to be aware that wire manipulation is often tricky, and …

Effective wiring technique is the key to success of PCI in CTO, which requires more patience and skill of the operator. The author herein intends to explore in detail the different wiring strategies such as antegrade approach, dissection and reentry, retrograde and hybrid approach.

Nov 12, 2024 · This review aims to outline how to perform a CTO analysis, clarify the fundamental features of guidewires and provide insights into both antegrade and retrograde wire-based approaches. Keywords

Jun 9, 2015 · Antegrade wire escalation is the most commonly used CTO crossing approach. 1,22 A microcatheter is advanced to the proximal cap of the occlusion, followed by crossing attempts using various guidewires. Currently, the most common initial guidewire choice is a soft tip, polymer-jacketed tapered guidewire (such as the Fielder XT, Asahi Intecc).
