PTFE Implant Covering

Aran Biomedical offers PTFE stent encapsulation services for balloon and self-expanding stents. The company has significant expertise covering even the most challenging stent geometries and ensures minimum impact to sheath size when moving from a bare metal design.  During the development phase, material encapsulation can be optimised to suit individual stent designs and the indication for use. Multi-axial laser processing ensures an optimum finish for the covered stents and the scope to integrate features into the stent wall.

PTFE (PolyTetraFluoroEthylene)

PTFE is a well-established biomaterial with a long clinical history of implantation. It has been approved by regulatory bodies for several decades and is used extensively in a range of vascular indications.
The unique physical & mechanical characteristics of PTFE enable it’s use as a stand-alone, surgically implanted material, or for direct attachment to an implantable frame for transcatheter delivery.
