What's more, radiation sometimes contributes to a blockage by exacerbating vessel damage at the edges of the stent
, Stone says.
The third type of stent
was a self-retaining H-shaped silicone tube, which was used for procedures that involved a type III revision (figure 3).
stated that, "These results have also led us to conclude that the CYPHER([R]) Stent
is clinically superior to bare-metal stents
and the Taxus Stent
when the safety and effectiveness outcomes in this analysis are taken into account.
A direct comparison of stenting and plaque-removing surgery, called endarterectomy, now finds that the two approaches benefit patients about equally, with a slight edge going to stents
, scientists report in the Oct.
Together this partnership will accelerate the commercialization of MIVT technologies that could successfully address the well publicized issues facing the current drug eluting stent
In the 1980s, scientists devised mesh cylinders called stents
that prop open the arteries after the balloon is withdrawn.
Unlike other stents
and techniques used to treat bifurcation lesions, Tryton's stent
is easy-to-deliver as it uses standard equipment and techniques compatible with 5 and 6 French guiding catheters.
Angioplasty and a stent
provided the less expensive approach but were more likely than bypass surgery to eventually lead to additional angioplasty or a follow-up round of bypass surgery, says study leader Patrick W.
Dake reported that the Zilver Drug eluting stent
showed an equal MAE rate to conventional angioplasty for treating SFA lesions.
After 1 year, only 8 patients given abciximab with a stent
had died, compared with 19 of those given a stent
without the drug and 17 who received angioplasty and abciximab.
The Company's novel polymer-free drug-eluting technologies based on Hydroxyapatite could also provide an attractive alternative to current polymer-based drug-eluting coatings on the stent
market, which have been associated with undesirable medical effects.
The Endeavor drug-eluting stent
system is an investigational device and not yet approved in the United States.
