Biodegradable stents: truly biodegradable with good tissue harmony

Biodegradable stents: truly biodegradable with good tissue harmony.

A 48-year-old man presented to our hospital with corrosive (sulfuric acid)-induced esophageal and pyloric strictures and a barium study showing narrowing of a long segment in the distal esophagus (●" Fig.1a), reduced capacity of stomach, and antropyloric narrowing (●" Fig.1b). Balloon dilation (Boston Scientific, Natick, Massachusetts, USA) of esophageal and pyloric strictures was done over a p...

Drug-eluting/biodegradable stents.

Computational modeling of coated biodegradable stents

Biodegradable stents are a promising technological development, as they temporarily support the stenotic blood vessel during its healing period, leaving no obstacle for possible future interventions and avoiding long term side effects of conventional drug eluting stents. Moreover, the biodegradable stent material forms an ideal vehicle for local drug delivery [1]. Finite element computer simula...

Water-dispersible and biodegradable polymer micelles with good antibacterial efficacy.

New amphiphilic ABC triblock copolymers have been designed and self-assembled into water-dispersible and biodegradable polymer micelles, which exhibit good antibacterial activities without quaternary ammonium moieties or the loading of any external antibiotics due to the increased local concentration of cationic charge in the polymer micelles compared to the un-self-assembled individual polymer...

Adverse cardiovascular events associated with biodegradable polymer drug-eluting stents and durable polymer everolimus-eluting stents

BACKGROUND Controversies have been observed among network meta-analyses comparing biodegradable polymer drug-eluting stents (BP-DES) with durable polymer drug-eluting stents (DP-DES). We aimed to compare the adverse cardiovascular events associated with BP-DES and durable polymer everolimus-eluting stents (DP-EES) using a large number of patients obtained from randomized controlled trials (RCTs...
