Benefit Of Bioabsorbable Stents Is That The Material Could Be Changed And Reused Over
A stent is a metal object that's either inserted into an artery or other internal urinary duct to expand
it to stop a blockage or facilitate passage of a fluid. Traditionally, they are constructed with flexible
metal mesh and stay within the body until removed via subsequent surgical intervention or through
recovery. With the utilization of bioabsorbable polymers, a new class of stents called
Bioabsorbable Stents have now been developed. This class of stents doesn't use metal mesh but
has a firm core full of a liquid to counteract urinary stream pressures and thus is suited to external
An important benefit of this sort of stent when compared with traditional metal or glass-based stents
is its use of easily available materials. In traditional stents, metal and glass are generally required.
Other metals such as for example tin, copper, and even asbestos are also used. Another major
benefit of Bioabsorbable Stents is that the material could be changed and reused over time. The
recyclability of PVB-stented polymeric membranes is one step more than that of conventional
materials like polyurethane or magnesium-based scaffolds.
The key disadvantage of those polymeric scaffolds, compared to materials such as for example
metal and glass-based ones, is that the scaffold's core is a liquid and is subject to wear and tear
consequently of experience of air and moisture. This makes the dissolving process slower with a
better possibility of structural failures. Another disadvantage is that the scaffold must have its inner
surface manufactured from a specific polymer. Polymer-based scaffolds are easier molded into
different shapes while maintaining their core function. This causes it to be easier to obtain a regular
thickness through the entire material.
