Anorectal physiology and biofeedback
Funded and developed by the NHS
Designed for use consistent with IAPWG and the London Classification for Disorders of Anorectal Function.
I came up with the concept of Anisys GO, a smaller, more cost effective and easier to use device for clinicians to address this unmet need and bring care closer to the patient’s home, reducing waiting times.’

The NHS is targeted to reduce waiting times, improve patient pathways and bring care closer to home (Reforming Elective Care for Patients, Jan 2025)
Anisys GO provides a quick and easy, comprehensive physiology assessment, earlier in the patient pathway to enable more appropriate referrals, thereby reducing backlog and fewer patient appointments (potentially closer to home).
'We are finding that our patients are better engaged and keen to come back to the clinic to track their progress with Anisys GO.
We believe that patients need fewer appointments due to their increased engagement.'

2005: Professor Shaheen Hamdy identifies a need for improved diagnosis and treatment of ano-rectal disorders, envisioning a portable, multi-functional device.
2005-2015: Collaborative research and technology development begins with University of Manchester support (UMIP/Innovation Factory, MIMIT).
2015-2018: Lucid Innovation joins the project, developing prototypes and securing NHS funding (SBRI Stage 1 & 2, Pitch for Titch). Paediatric applications are explored with Alder Hey and Royal Manchester Children’s Hospitals, and Bladder & Bowel UK.
2019: Health Innovation Manchester Momentum Award funds integrated care pathway development, involving nurses, clinicians, and physiotherapists.
2020: Distribution agreement signed with deSmit Medical for the Anisys GO range.
2020-2023: Lucid funds and manages ongoing development, manufacturing, usability studies, and regulatory processes.
2023: UKCA mark achieved; deSmit Medical begins UK distribution.
2023-2024: Innovate UK funding secured with Bladder & Bowel UK to integrate patient diaries and forms into Anisys GO.
