The BridgePoint devices to facilitate recanalization of chronic total coronary occlusions through controlled...

Area of Science:

• Interventional Cardiology
• Medical Device Technology

Background:

• Chronic total coronary occlusion (CTO) presents a significant challenge in interventional cardiology.
• Despite advances like drug-eluting stents, CTO procedures have a low primary success rate, often due to difficulties in wire navigation.
• Failure typically stems from inability to cross the proximal cap or guide the wire into the distal true lumen, frequently resulting in subintimal positioning.

Purpose of the Study:

• To introduce the BridgePoint family of devices designed to overcome CTO procedural challenges.
• To describe the CrossBoss catheter's function in traversing the proximal occlusion cap.
• To explain the Stingray balloon's role in facilitating true lumen reentry from a subintimal space.

Main Methods:

• Utilizing the CrossBoss catheter with its blunt tip for manual rotation to penetrate the proximal cap.
• Employing the Stingray balloon for controlled reentry into the distal true lumen when wire position is subintimal.
• Evaluating the potential for these devices to be used independently or as a bailout strategy.

Main Results:

• The CrossBoss catheter facilitates passage through the proximal cap.
• The Stingray balloon enables guided reentry from the subintimal space into the true lumen.
• These devices offer an alternative to complex and potentially riskier retrograde techniques.

Conclusions:

• The BridgePoint device system addresses key failure modes in CTO interventions.
• These tools can improve success rates and simplify procedures, potentially reducing the need for retrograde approaches.
• The CrossBoss and Stingray offer a valuable solution for otherwise failed CTO attempts.
