A ground-breaking invention which clears smoke created during surgery has created clear economic impact and societal benefits for patients worldwide.

Reducing surgical smoke

Surgical smoke is a significant issue during laparoscopic surgery. Smoke created by cutting instruments rapidly builds up in the abdominal cavity, severely impairing the quality of the visual field and slowing down the procedure. The subsequent release of surgical smoke into the operating theatre is also unpleasant for the surgical team and there is a potential risk that chronic exposure may have long-term health implications.

Over six million laparoscopic procedures are carried out globally every year. Research and feedback shows previous products are largely ineffective in meeting the needs of the surgical team. The solution, Ultravision™, was conceived by Dr Neil Warren, a specialist at the forefront of minimally invasive surgery training at Cardiff University.

The ground breaking invention silently, effortlessly and unobtrusively clears the visual field of surgical smoke and prevents its release in to the operating theatre to allow best practice in laparoscopic surgery. UltravisionTM is the first product to be launched by Alesi Surgical (previously Asalus Medical Instruments Limited), the company established to commercialise the inventions of the Welsh Institute of Minimal Access Therapy (WIMAT).

The technology underpinning Ultravision™, electrostatic precipitation, is the subject of three patent filings originally identified by Dr Eryl (Cox) Francis, Commercial Development Manager during a meeting with the inventor, the first of which is now granting in territories worldwide.


Ultravision™ won the 2013 Cutlers Prize awarded by the UK's Royal College of Surgeons for outstanding advance in design of a surgical instrument or technique. The company won the UK's Praxis Unico Impact Award for Business Aspiring in 2014, and the MediWales Innovation Award 2014. It also won the New Ventures and People's Choice awards at the 2014 Cardiff University Innovation Network Awards ceremony.

Furthermore, Ultravision™ was awarded the CE mark in 2014, allowing hospitals to use the system on patients undergoing laparoscopic surgery in the European Union member states.

The company has since appointed distributors in 25 countries and secured £2.1m to drive the further commercialisation of its lead product. The new investment provides capital to drive adoption of Ultravision, which has already been trialled across a spectrum of the most commonly performed laparoscopic procedures in gastrointestinal, gynaecological, urological and colorectal surgery.

The Ultravision story has been an excellent example of best practice collaborative IP commercialisation. Cardiff University immediately recognised the potential value, rapidly filed IP and provided translational funding to create prototypes. The commercialisation team then secured funding from Fusion IP, Finance Wales and IP Group to create Asalus. Five years later we have a launched product and are attracting distribution partners in 25 countries worldwide, and we are working towards an FDA regulatory submission this year.
