BIOABSORBABLE RAPAMYCIN ELUTING
CORONARY STENT SYSTEM
Bioheart bioabsorbable drug-eluting stents provide good biocompatibility and its degradation products can be absorbed by the human body. Based on its own function, the product can repair and reconstruct tissue function for patients, specifically revascularization, functional recovery and stent absorption. During the revascularization period, the stent provides radial support to the vessel at the lesion site, lasting for no less than 6 months (clinical results show that the lumen diameter tends to be stable about 3 months after PTCA). With the precise release control design of the drug coating, the stent can adequately endothelialize (the stent structure is completely covered by neointima, and the degradation debris will not protrude into the blood vessel to avoid affecting blood flow or developing embolism).During the functional recovery period of PTCA, the stent no longer restricts the contraction and expansion of blood vessels, allowing them to make natural responses to physiologic stimulation and gradually reduces the radial strength, until it loses structural continuity in the course of self-degradation. In the absorption phase, the stent is degraded into carbon dioxide and water, which is absorbed benignly by the human body.
ULTRA THIN-WALL BIOABSORBABLE
RAPAMYCIN ELUTING CORONARY
STENT SYSTEM
A thinner-wall generation of fully absorbable coronary stents has the minimum thickness, less than 100μm. With a thinner wall, the product will bring the following benefits.
① Brings a smaller profile (contour diameter) of the stent, offering better controllability and flexibility, and providing convenience for the operator to deliver the stent to the target lesion;
② A thinner wall enables good lumen gain immediately after stent implantation;
③ Better stent apposition after implantation;
④ There is minimal turbulence around the stent struts, reducing the possibility of aggregation of platelets to cause thrombus in stent;
⑤ More consistent Endothelialization of the stent after implantation;
⑥ The thinner-wall stent reduces the number of implants, which is beneficial to absorption by the human body;
