Extracorporeal circulation is the only method used during cardiovascular surgery and requires the use of cannulas which are inserted into the arterial vessels: the cannulas on the market are unidirectional and only allow blood flow towards the heart. Especially in peripheral arterial cannulation, these cannulas can cause hypoperfusion distal to the cannula insertion site, potentially leading to ischemia of the affected organ.
The present invention proposes a multidirectional cannula that can be used both for surgical and percutaneous insertion. This also allows perfusion of the tissues located distal to the cannula itself, thus obviating the problem of hypoperfusion and related ischemic damage.
Therefore, without additional surgical procedures, this cannula would allow insertion on the arterial vessel (for example the femoral artery) with the usual method, and the multi-fenestrated basket design would provide adequate anchoring, whilst allowing blood flow in both retrograde and antegrade directions, ensuring both distal and proximal perfusion.

  • Walking simulator for prosthetic device testing

    The object of the patent is a walking simulator capable of reproducing the kinematics and kinetics of the leg during a wide variety of gait-related tasks (level/inclined/stairs walking...) and walking conditions (uneven/wet/muddy terrains...), with the purpose of collecting meaningful data[...]

  • miRNAs as diagnostic and prognostic biomarkers of oral squamous cell carcinoma

    In the last decades, the incidence of oral squamous cell carcinoma (OSCC) has been constantly increasing, yet the survival outcomes have remained essentially unchanged. This, in part, is due to a lack of efficient, non-complex and rapid diagnostic and prognostic[...]

  • Alternative arthropathy treatment

    The combined effect of the BPI protein (bactericidal/permeability-increasing protein) and hyaluronic acid has proven effective for the treatment of arthropathies. It may integrate or replace current anti-inflammatory therapies that at times have serious side effects. This pharmaceutical combination that contains[...]
