Brief Summary:
Prospective, non-randomized, multicenter study in subjects with coronary artery chronic total occlusions (CTOs). Published results of safety and effectiveness of conventional techniques will be used for comparison. Enrollment of up to 149 subjects with a CTO refractory to currently marketed guidewire use and meeting all inclusion/exclusion criteria at up to 15 US clinical sites. Hypothesis is that the BridgePoint Medical System is safe and effective in treating coronary CTOs compared to CTO literature.

Condition or disease Intervention/treatment Phase
Coronary Artery Chronic Total Occlusion Device: Recanalization of a coronary chronic total occlusion Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 147 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Facilitated Antegrade Steering Technique in Chronic Total Occlusions
Study Start Date : March 2009
Actual Primary Completion Date : August 2010
Actual Study Completion Date : September 2010

Arm Intervention/treatment
Experimental: BridgePoint Medical System
Attempt to cross CTO with the BridgePoint Medical System after an attempt to cross the CTO with a currently marketed guidewire
Device: Recanalization of a coronary chronic total occlusion
Crossing a CTO to allow definitive treatment via balloon angioplasty and/or stent placement
Other Names:
  • CrossBoss Catheter
  • Stingray Catheter
  • Stingray Guidewire

Primary Outcome Measures :
  1. Technical Success [ Time Frame: Intraprocedural ]
    Defined as the ability of the BridgePoint Medical System to successfully facilitate placement of a guidewire beyond a chronic total occlusion (CTO) in the true vessel lumen in cases that were otherwise refractory to treatment with a currently marketed guidewire

  2. 30-day Major Adverse Cardiac Event (MACE) Rate [ Time Frame: 30 Days ]
    Defined as cardiac death, Q-wave and non-Q-wave [total creatinine kinase (CK) >2x upper limit of normal with a positive myocardial band (MB) fraction] myocardial infarction (MI), target lesion revascularization (TLR), and emergency bypass surgery.

Secondary Outcome Measures :
  1. Total Procedure Time [ Time Frame: Intraprocedural ]
    Minus any time to determine CTO was refractory to standard guidewire

  2. Total Procedural Fluoroscopy Time [ Time Frame: Intraprocedural ]
    Minus any time to determine CTO was refractory to standard guidewire
