View clinical trials related to Chronic Total Occlusion.
Filter by:Observational retrospective registry to compare effectiveness of paclitaxel-coated vs. non coated balloon angioplasty proximal to a Chronic Total Occlussion (CTO) after failed revascularization. Primary objective is to determine success rate after repeated percutaneous coronary intervention of a CTO 3 to 6 months after paclitaxel-coated balloon angioplasty proximal to the persistent lesion.
This is an open label, single-center, prospective, pivotal study in which the investigational device, NovaCross™ micro-catheter, will be tested in up to 15 patients scheduled to undergo CTO-PCI using an anterograde approach.
This is prospective cohort study in subjects with a planned percutaneous coronary intervention (PCI) of their chronic total occlusion (CTO). The study will enroll subjects who have been scheduled for a clinically-indicated cardiac catheterization, and will evaluate coronary microvascular function in all subjects meeting inclusion criteria with a coronary flow wire. Evaluation of coronary microvascular function may be performed using indirect methods, however the rationale behind the present study is to directly measure microvascular function using direct coronary flow measurements, since the subjects in the study are to undergo a clinically-indicated cardiac catheterization. The overall purpose of the study is to define the presence and severity of coronary microvascular dysfunction subjects with CTO. The study is designed to enroll 50 subjects with CTO in the span of 3 years. There will be a 6-month assessment of the outcomes of death and cardiovascular death. As the study includes FDA approved tests, there will be no safety endpoint per se, however there will be a mechanism for monitoring adverse events as will be described in detail.
The objective of this study is to evaluate angiographic confirmation of placement of any guidewire beyond the CTO, in the true vessel lumen, in patients undergoing CTO percutaneous coronary intervention (PCI) in which at least one Teleflex guidewire and at least one Turnpike catheter are used.
Trial is to evaluate the safety and performance of the NovaCross™micro-catheter in respect to providing additional guidewire support that is expected to allow easier crossing of femoropopliteal and infra-popliteal Chronic Total Occlusion (CTO) lesion. The procedure will be conducted on a patient diagnosed with a CTO in a peripheral vessel that requires revascularization.
Study of the OffRoad™ Re-entry Catheter System for subintimal recanalization of chronic total occlusions in native femoropopliteal arteries.
Study of the BridgePoint Medical System in the crossing of chronic total occlusions of the lower extremities.
The aim of the study is to assess the safety and efficacy of a Paclitaxel-eluting PTCA-balloon in combination with bare-metal stenting for treatment of chronic total occlusions in native coronary arteries with reference diameters between 2.5 mm and 4.0 mm.
