The primary objective of this prospective, multicenter, single arm clinical study is to compare the rate of procedure success of the coraCross, coraForce, and coraFlex catheters in facilitating guidewire placement beyond coronary chronic total occlusions to a pre-defined performance goal based on literature. The study population will consist of those 18 years or older with symptomatic ischemic heart disease, undergoing clinically indicated percutaneous recanalization of an occlusive coronary lesion, and meeting all other eligibility criteria. Measures will be assessed through 30 days post-intervention.
The goal of this clinical trial is to evaluate the safety and effectiveness of the coraFlex, coraForce, and coraCross catheters for crossing chronic total occlusions of the coronary arteries. The study will compare the rate of procedure success to success rates from previous trials.~Participants will undergo percutaneous coronary intervention (PCI) for a chronic total occlusion and be followed for 30 days post-procedure.
