  • miniature uniaxial force sensor for use within a beating heart during mitral valve annuloplasty
  • provides a hollow core to pass instrumentation
  • Fiber optic transduction eliminates electrical circuitry within the heart, and acetal components minimize ultrasound-imaging artifacts
  • ...4 more annotations...
  • 0–4-N force range
  • errors of 0.13 N (<3.2%)
  • MINIMALLY invasive surgery (MIS)
  • surgeons lose the critical sense of touch during MIS because instruments are passed through ports that mask the surgeon's feel of the internal operating environment.
