CORONARY INTERVENTION - XPERIA
Xperia - Stainless Steel Coronary Stent System
Stent & balloon induced acute mechanical arterial injury during expansion is an important determinant of restenosis. The cellular signaling mechanisms that result in platelet deposition, thrombus formation, & smooth muscle cell proliferation begin in response to arterial injury. It has been shown that deep injury to the media & superficial injury to the endothelium occur during stent expansion. Stent implantation imparts extreme vascular strain & focal mechanical injury to the vessel wall ranging from denudation of the endothelial cell mono layer, to progressive laceration of the deeper vascular structures. The amount of injury inflicted by the stent and balloon is a function of stent geometry.
Xperia coronary stent is the next generation Uniform sinusoidal cell geometry stent, designed to minimize stent induced arterial injury. It is carefully designed to incorporate controlled stent expansion characteristics, better stent-artery compliance, superior acute gain, optimum cell sizes & shape, lower strut thickness and high flexibility.
 

Unique Design Features

Unique edge design offers controlled stent expansion.

Edge injuries are caused by both stent edge flaring during expansion & balloon "Dog Boning". Conventional stent designs expand as "Edge First Expansion" resulting in injury at the edges. The stent balloon mismatch also causes injury at the edges due to "Dog Boning" effect. Xperia incorporates wide closed cells at the stent edges that will minimize edge flaring & knife edge focal injury during expansion. Also the stent & balloon is precisely matched to minimize "Dog Boning" effect.
 

Optimum cell size & shape

Generally during stent expansion, due to the intra cellular balloon protrusion, the expansion energy from the balloon is transferred to the arterial wall causing injuries. This is cell size & shape dependent. Xperia has optimum cell size & shape to minimize injuries.
 

Lower strut thickness

Xperia has thin struts to minimize focal mechanical injury to the vessel wall.
 

Better stent artery compliance

During the stent expansion, artery experiences extreme strain. Greater the strain greater is the injury. Xperia is designed to minimize arterial strain due to stent-artery compliance mismatch.
 

Superior acute gain-more vessel area

Xperia tends to recoil less than 2% when fully expanded, whereby offering superior acute & more vessel area.
 

High flexibility & lower crossing profile to address complex anatomies.

Lower strut thickness offers lower crossing profile & multi axial high flexibility while negotiating complex anatomies. Vessels do not tend to straighten after the stent expansion.

designed for optimal strength and flexibility
