Brief Summary:
The primary objective of this study is to compare the safety and performance of the Palmaz Genesis™ balloon expandable stent, with or without sirolimus coating in the treatment of renal artery stenosis, measured at 6 months follow up via angiography.

Condition or disease Intervention/treatment Phase
Renal Artery Stenosis Device: Sirolimus-eluting Palmaz Genesis peripheral stent Phase 2

Detailed Description:

Multi-center, prospective, controlled, non-randomized investigational feasibility study. One hundred (100) patients with de novo or restenotic renal artery lesions consisting of >= 50% stenosis and reference vessel of >= 4.0 to <= 8.0 mm in diameter will be sequentially included, 50 without sirolimus coating, followed by 50 with sirolimus coating Palmaz GenesisTM. Patients will be followed for 24 months post-procedure, with all patients having clinical assessments at discharge, 1,6, 12 and 24 months. This study will be conducted at twelve investigational sites.

It is anticipated that the total length of time required to complete the study will be 46 months.
