ABSTRACT:
A method and systems for treating chronic total occlusions, particularly those that are difficult to treat, is disclosed. In this approach, recanalizing the CTO is achieved using a combined antegrade and retrograde approach. The proximal end of the occlusion is penetrated using an antegrade wire, using a traditional approach. Using collateral vessels, the distal end of the occlusion is crossed in a retrograde fashion and by appropriately maneuvering each member, a continuous channel is created. Additional elements such as capture devices, dilators and injection catheters are also disclosed.
