N-DEAVOUR®, produced by N-ovative Health Technologies (NHT), is Pakistan’s first Drug Eluting Coronary Stent System which prevents the recurrence of late stent restinosis. The drug in the mechanism is released in a controlled manner over time to not only save the coronary artery from future blockade, which is the mechanical function of a stent, but also from unhealthy cell growth as a response, which has been experienced widely by patients who implant a Bare Metal Stent.

Technical Details

N-DEAVOUR® is a combination product comprised of two key components: the stent (which includes a base coat of Poly Butyl Methacrylate (PBMA) and a top coat of PVDF-HFP (non-erodable polymer) and the active pharmaceutical ingredient Everolimus.

N-DEAVOUR® has an MP35NLT Cobalt-Chromium (major elements include Cobalt, Nickel, and Chromium) stent platform and is pre-mounted on a PTCA Balloon Dilatation Catheter

Everolimus is the active pharmaceutical ingredient in the N-DEAVOUR® stent. It is a semisynthetic macrolide immunosuppressant, synthesised by chemical modification of rapamycin (sirolimus). Drug content is 100µg/cm² Everolimus per/mm². The drug load is 100 μg/cm2 for all product sizes. The drug load is 100 μg/cm2 for all product sizes.

N-DEAVOUR® stent contains inactive ingredients including Poly N-Butyl Methacrylate (PBMA), a polymer that adheres to the stent and drug coating, and PVDF-HFP, which is comprised of vinylidene fluoride and hexafluoropropylene monomers as the drug matrix layer containing Everolimus.

PBMA is a homopolymer with a molecular weight (Mw) of 264,000 to 376,000 dalton. PVDF-HFP is a non-erodible semi-crystalline random copolymer with a molecular weight (Mw) of 254,000 to 293,000 dalton. The drug matrix copolymer is mixed with Everolimus (83%/17% w/w polymer/Everolimus ratio) and applied to the entire PBMA coated stent surface.

Product Illustrations

N-DEAVOUR®s Everolimus Eluting Coronary Stent System comprises two components:

Cardiovascular Implant

Cobalt-Chromium Bare Metal Stent

Delivery System

Rapid Exchange Semi Compliant Percutaneous Transluminal Angioplasty (PTCA) Balloon Catheter

Stent is mounted (crimped) on balloon portion of catheter
  • Gauge length of balloon is always kept 2±0.5 mm larger than the total length of stent.
  • Length of stent has a tolerance of ±0.5mm.
  • X-ray marker is placed inside the edge of gauge length of balloon, X-ray marker’s width is 1±0.25 mm.
  • Stent is placed in between two X-ray markers; distance from edge to edge of stent and X-ray marker is 1±0.5mm on each side.
Product Standard Compliance

N-DEAVOUR® stent is manufactured using biocompatible materials in compliance with EN ISO 10993-1 and is safe and compatible to Magnetic Resonance Imaging (MRI) environment in compliance with ASTM F2503, ASTM F2052, ASTM F2119, ASTM F2182, ASTM F2213.
