PTQ Implants

PTQ is an injectable soft-tissue bulking agent for implantation in the Internal Anal Sphincter (IAS) used to treat passive faecal incontinence due to a weak or disrupted internal anal sphincter.

The procedure is minimally invasive and technically simple (Ref 1). It can be performed under local anaesthesia in an outpatient setting.


Proven Performance

  • Up to 95% of patients show a significant improvement in incontinence scores (Ref 2,3)
  • Provides sustainable improvement for 12-24 months (Ref 2-10)
  • Improves patient quality of life (Ref, 2-4, 7, 11)
  • Reinjection is safe and effective (Ref 5)
  • Helps improve anal asymmetry index which may be linked to increased maximum resting anal canal pressures (Ref 2)
