简要总结
The objective of this study is to assess the performance and safety of a formulation of the antiproliferative agent, sirolimus coated on modified Bx VELOCITY Balloon-Expandable Stent mounted on the Raptor Over The Wire (OTW) Stent Delivery System (SDS) in patients with de novo coronary artery lesions.
详细描述
This is a single center, non-randomized study. Patients who meet the eligibility criteria will be treated with the sirolimus coated modified Bx VELOCITY Balloon-Expandable Stent mounted on the Raptor OTW SDS. Patients will be followed for five years post-procedure, with all patients having a repeat angiography at 6 months, 18 months, and 48 months.
