Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - MiStent DES
Treatment: Devices - Endeavor DES

Experimental: MiStent DES - The MiStent SES is a sirolimus-eluting absorbable polymer stent for coronary artery revascularization.

Active comparator: Endeavor DES - The Endeavor DES is an everolimus-eluting durable polymer stent for coronary artery revascularization.


Treatment: Devices: MiStent DES
The MiStent is a device/drug combination comprised of two components; a stent and a drug product (sirolimus within an absorbable polymer coating).

Treatment: Devices: Endeavor DES
The Endeavor is a device/drug combination comprised of two components; a stent and a drug product (everolimus within a durable polymer coating).
