Stent Inventor's New Ideas

Abstract:
Stent pioneer Dr. Julio Palmaz was in the news this week regarding a $3 million investment made in his company Palmaz Scientific by the State of Texas. According to the San Antonio Express-News, the state's Emerging Technology Fund (ETF) investments "are designed to help start-up companies get their technology out of the lab and into the marketplace. The investments also give the state an equity position in the start-ups."

His company's technology utilizes nanotechnology and physical vapor deposition (PVD) to yield material of higher purity, lower profile and a micro-grooved flow surface so that the stent can have an all metal micromesh covering only 5 microns thick (about the size of a blood cell) with openings less than 100 microns. The concept is that this covering can act as a screen to prevent migration of the stent struts into the plaque, which can cause inflammation and embolization of the plaque, and that it can promote healing, resulting in reduced restenosis without having to subject the patient to long-term dual antiplatelet therapy or the risk of late stent thrombosis.
