3. Subjects with contralateral disease of the common femoral vein, external iliac vein, common iliac vein, or any combination thereof with planned treatment within 30 days after enrollment
4. Subjects with a life expectancy \< 12 months
5. Female of childbearing potential who is pregnant or plans to become pregnant during the duration of the clinical study (Note: subjects who plan to become pregnant after 12-month follow-up visit may be included in the trial at the discretion of treating physician)

2. Subjects where the obstruction extends into the inferior vena cava or below the level of the lesser trochanter
3. Subjects whose vein diameters are not within limits stated in the Instructions for Use of study device as determined by venogram and/or IVUS
4. Subjects who do not meet the venogram or IVUS binary stenosis by the definition above (IC3), as determined by the treating physician
5. Subjects who are judged by treating physician to have a lesion that prevents completed inflation of a balloon dilation catheter or proper placement of the stent or the stent delivery system
