DOYLESTOWN, Pa., May 29 Three patients with establishedcardiac ischemia recently became the first recipients of the vProtect LuminalShield, a self-expanding intracoronary prosthesis designed to limit arterialinjury that typically occurs when stents are deployed. The Shield alsoprovides robust biocompatible support for the vessel to ensure that the targetcoronary artery will remain patent after placement.

The patients were treated May 8-9 by Juan F. Granada, MD (CardiovascularResearch Foundation, New York, NY) and Juan A. Delgado, MD (CorbicInstitute-MUA) at the Corbic Institute-MUA in Envigado, Colombia. The targetlesions ranged from 60% to 80% stenosis before the vProtect Luminal Shieldswere deployed.

In the first patient, a 75% occlusion in the mid-circumflex coronaryartery underwent pre-dilatation at low pressure with a 2.5 x 9 mm balloon andthen received a 3.5 x 15 mm luminal shield. After gentle post-dilatation,angiography revealed that blood flow had been restored to the distal portionof the treated vessel.

In the second patient, an 80% occlusion in the middle of the left anteriordescending (LAD) branch required pre-dilatation with a 2.5 x 9 mm balloon.Additional lumen gain was achieved by Shield placement and post-dilatation,again achieving restoration of blood flow distal to the treated segment.

The third patient was a challenging case with a 65% occlusion in themid-LAD, located in a bend near a side branch ostium. The vProtect LuminalShield was chosen for this patient based on its mechanical properties,including high vascular conformability. Because of its flexibility, thevProtect Luminal Shield was able to access the tortuous anatomy and cross thelesion successfully. Restoration of flow was achieved without angiographicevidence of straightening of the target vessel, a common occurrence with rigidballoon-expandable stents. In addition, the side branch was preserved withoutevidence of plaque shifting or worsening stenosis.

"The vProtect Luminal Shield and delivery system performed extremelywell," according to Dr. Granada. "The three patients we treated presented withlesions representative of what we see in daily clinical practice and we wereable to cross these lesions and deliver the device safely in each case.Although the vProtect Luminal Shield has ultra-thin struts to promote healing,it maintains an intrinsic radial force that matches the vessel compliance. Iam very pleased with these early results," Dr. Granada said.
