Advanced Materials

Specialty needles for complex diagnostics and treatments demand advanced performance characteristics such as the ability to negotiate tortuous anatomy, advanced visibility features or sharpness maintenance under repeat use.

Advanced materials such as Javelin™ contribute to advanced performance.

Javelin™ is a high performance alloy for specialty needle applications that enables better surgical outcomes.  The alloy is optimized for longer needles that must navigate long and complex anatomical paths or needles that sample difficult tissue types such as those with a dense mass.

Javelin™ enables better clinical outcomes through:

  • Superior physician control
  • Accurate navigation to sample site
  • Easier biopsy penetration
  • Maintenance of needle efficacy during repeat deployment
 

Superior Penetration

Javelin™ has greater penetration ability and exhibits superior hardness over Stainless Steel. In tests, Javelin™ demonstrated up to 24% increased hardness over 304SS.

Penetration Test

19G electro polished needles – Javelin™ and 304SS, with the same tip design were tested for penetration ability. Each needle was loaded in a mechanical tester and advanced under equal test parameters to penetrate a 3mm membrane - simulating in vivo use. 

304 SS 19G needle

  

           Needle is advanced               Needle reaches membrane      Needle buckles, fails to penetrate 

Javelin™ 19G needle


 

          Needle is advanced                 Needle reaches membrane            Needle penetrates

This test demonstrates that Javelin™ successfully penetrated the membrane while the Stainless Steel needle buckled and failed to penetrate the membrane.

Javelin™ - repeat deployment


The 304SS needle is permanently deformed after failing to penetrate the membrane. The Javelin™ needle both successfully penetrated the membrane and is capable of repeat deployment.
