Pioneering the use of compliant mechanisms, Tranquil is a flexible interbody device.

Spinal bone is 1/7 the stiffness of PEEK. Tranquil is too. And it matters.

Tranquil is different than any other interbody. Contact us to see the data.



Tranquil matches the stiffness of spinal bone. PEEK doesn’t, it is substantially stiffer than spinal bone. 3D titanium implants are even stiffer than PEEK.1

Loaded just below the force required for burst fracture.



Tranquil’s chemistry, surface energy, roughness, and texture make it more osteoinductive and more osteoconductive than predicates.2


Tranquil’s pore size, shape, volume and flexibility provides substantially more bone thru-growth than predicates.3
